    SUMMARY: The Intermodal Surface Transportation Efficiency Act of 1991 
    (ISTEA) restricts the operation of longer combination vehicles (LCV's) 
    on the Interstate Highway System and commercial motor vehicle (CMV) 
    combinations with two or more cargo-carrying units on the National 
    Network (NN) to the types of vehicles in use on or before June 1, 1991, 
    subject to whatever State restrictions were in effect on that date. The 
    ISTEA also includes special variances from the June 1 date for Alaska, 
    Ohio, and Wyoming. As required by the ISTEA and based on information 
    provided by the States, industry, and the public, the final rule lists 
    applicable limitations by specific vehicle combination, by State, in 
    effect on June 1, 1991, and does not further restrict the operation of 
    any vehicle in lawful operation on or before June 1, 1991. This rule 
    also establishes criteria for States to make minor adjustments to the 
    list of limitations; defines certain terms, such as ``nondivisible 
    load,'' ``beverage container,'' and ``maxi-cube'' vehicle; makes 
    technical amendments to the list of federally-designated routes on the 
    NN; and makes other minor changes to conform existing regulations to 
    the ISTEA.
    
    EFFECTIVE DATE: July 13, 1994.
    
    FOR FURTHER INFORMATION CONTACT: Mr. Thomas Klimek, Office of Motor 
    Carrier Information Management, at (202) 366-2212 or Mr. Charles 
    Medalen, Office of the Chief Counsel, at (202) 366-1354, Federal 
    Highway Administration, Department of Transportation, 400 Seventh

    SUPPLEMENTARY INFORMATION: Section 1023 of the ISTEA (Pub. L. 102-240, 
    105 Stat. 1914, 1951, codified at 23 U.S.C. 127(d)) required States, 
    within 60 days of the date of enactment, to submit to the Secretary of 
    Transportation for publication in the Federal Register 30 days 
    thereafter a complete list of (1) all operations of LCV's being 
    conducted as of June 1, 1991; (2) State laws, regulations, and any 
    other limitations and conditions, including routing-specific and 
    configuration-specific designations governing the operation of LCV's; 
    and (3) a copy of such laws, regulations, limitations, and conditions. 
    An LCV is defined in the ISTEA as any combination of a truck tractor 
    and two or more trailers or semitrailers which operates on the 
    Interstate System at a gross vehicle weight greater than 80,000 pounds.
        Similarly, section 4006 of the ISTEA (49 U.S.C. app. 2311(j)) 
    required the States to submit a complete list of State length 
    limitations applicable to CMV combinations with two or more cargo-
    carrying units in effect on or before June 1, 1991. This section 
    prohibits States from allowing the operation (by statute, regulation, 
    permit, or other means) of CMV's with cargo-carrying unit lengths that 
    exceed the length, by specific configuration, allowed and in actual, 
    lawful operation on a regular or periodic basis (including continuing 
    seasonal operation) on the NN in that State on or before June 1, 1991. 
    The NN is defined in 23 CFR 658.5, and includes the Interstate System, 
    with minor exceptions, and selected non-Interstate routes. The non-
    Interstate NN highways are listed in appendix A to part 658.
        Sections 1023 and 4006 provide that no statute or regulation shall 
    be included on the list submitted by a State or published by the 
    Secretary merely on the grounds that it authorized, or could have 
    authorized, by permit or otherwise, the operation of LCV or CMV 
    combinations not in actual operation on a regular or periodic basis on 
    or before June 1, 1991.
        States may continue to issue special permits, in accordance with 
    applicable State laws, for those vehicles and loads which cannot be 
    easily dismantled or divided. A definition of such nondivisible loads 
    is included in this final rule.
        The ISTEA included three narrow exceptions to the June 1, 1991, 
    freeze date. Wyoming would have been able to allow the operation of 
    additional vehicle configurations not in actual operation on June 1, 
    1991, provided they were authorized by State law not later than 
    November 3, 1992. No additional vehicles were authorized, however, and 
    accordingly no additional vehicles are included in appendix C over 
    those listed in the previous two rulemakings on this issue.
        Ohio may allow LCV's with three cargo-carrying units of 28.5 feet 
    each (not including the truck tractor) not in actual operation on June 
    1, 1991, to be operated within its boundaries on the 1-mile segment of 
    Ohio State Route 7 which begins at, and extends south of, Exit 16 on 
    the Ohio Turnpike. Alaska may continue to allow the operation of CMV's 
    which were not in actual operation on June 1, 1991, but which were in 
    actual operation prior to July 6, 1991.
        A preliminary list of the information provided by the States in 
    response to sections 1023 and 4006 was published in the Federal 
    Register as a notice of proposed rulemaking (NPRM) on March 20, 1992 
    (57 FR 9900). A second proposed list of vehicles and restrictions, 
    including corrections, clarifications, and additional material 
    submitted to the docket in response to the NPRM was published as a 
    supplemental notice of proposed rulemaking (SNPRM) on February 25, 1993 
    (58 FR 11450). In the NPRM the information provided by the States was 
    organized into appendices C and D to part 658; in the SNPRM that 
    information was combined into a single list of vehicles and 
    restrictions and presented as a new appendix C. The format of the SNPRM 
    has been retained for the final rule.
        In response to publication of the SNPRM, 154 sets of comments were 
    received from 136 separate entities. The vast majority of those 
    comments deal with specifics on the information published in the SNPRM, 
    and they will be discussed under individual topical headings. Four of 
    the commenters, however, the American Trucking Associations, Inc. 
    (ATA), the Wyoming Trucking Association, Inc. (WTA), the Alaska 
    Department of Transportation and Public Facilities, and the Citizens 
    for Reliable And Safe Highways (CRASH), provided comments concerning 
    the rulemaking in general, and the philosophy used by the FHWA in 
    presenting the information. These particular comments provide an 
    opportunity for the FHWA to explain its approach.
        The ISTEA stipulates that the ``final list'' of LCV operational 
    requirements for each State be published in the Federal Register not 
    later than 180 days after the date of enactment. That date was June 15, 
    1992. The lead comment by the CRASH in its docket submission was that 
    publication of the final list by the FHWA was ``long overdue.'' The 
    CRASH contends that since the freeze does not take effect until the 
    Secretary publishes the final list, the FHWA's delay in publication has 
    prevented the law from taking effect. This in turn means that LCV's may 
    today be operating on highways from which Congress intended they be 
    barred. It concludes this comment by stating that the review and 
    correction process included with the final rule can be used to make 
    corrections after publication of the rule.
        As the FHWA stated in the Supplementary Information section of the 
    SNPRM, the content of the States' original responses to the ISTEA 
    request for LCV operational information covered the full range of what 
    could be supplied, both in terms of items covered and volume of 
    material. The diversity of the contents of the responses was so great 
    that the FHWA determined that before any list could be finalized, 
    increased uniformity both in terms of items covered and the type of 
    information would be necessary. Thus, despite the likelihood that the 
    statutory due date for a final rule might be missed, the FHWA 
    determined that it was in the public's interest to publish a SNPRM 
    soliciting further public comment on revisions to the initial list. The 
    FHWA considered publishing a ``final list'' without this additional 
    public procedure, but believed that the list published at that stage 
    would have required numerous subsequent changes. We believe that the 
    intent of Congress in including a correction process was to take care 
    of relatively minor single-issue situations which may be discovered 
    after publication of this final rule, not to make wholesale changes in 
    a State's submission without good cause.
        The WTA expressed concern that the interpretations used by the FHWA 
    in developing this rule have involved many combination vehicles that, 
    until passage of the ISTEA, were not considered by anyone to be LCV's. 
    In a similar vein, Alaska commented that the SNPRM ``seeks to 
    significantly expand the ISTEA legislation and, we believe, severely 
    constrains the states' abilities to legitimately regulate commercial 
    traffic within each state.''
        This final rule implements two similar, yet separate provisions of 
    the ISTEA. Section 1023, as discussed earlier, involves LCV's and 
    includes an LCV definition. The scope of vehicle combinations covered 
    by this section is narrow. The definition requires that an LCV 
    combination include a truck tractor, which by previous congressional 
    action (section 411(f), Surface Transportation Assistance Act (STAA) of 
    1982) is defined as a noncargo-carrying power unit and two or more 
    trailers or semitrailers. The combination must operate on the 
    Interstate System, and its gross vehicle weight must be in excess of 
    80,000 pounds. The vehicles listed in appendix C as a result of this 
    statutory definition include only what might best be described as the 
    ``traditional'' LCV's, that is, the ``Rocky Mountain'' and ``Turnpike'' 
    Doubles and the ``Triple.'' Under the definition of LCV provided by the 
    ISTEA, it is true that the State of Alaska has no LCV's because it has 
    no Interstate System mileage in the sense used in the ISTEA; that is, 
    Alaska does not have Interstate System mileage designated under 23 
    U.S.C. 103(e), 139(a), or 139(b). Accordingly, all references to LCV's 
    for Alaska have been deleted from this final rule.
        Alaska does, however, have mileage that is part of the NN. Section 
    4006 of the ISTEA requires the FHWA to include in the final list ``any 
    commercial motor vehicle combination * * * with 2 or more cargo 
    carrying units.'' A ``cargo-carrying unit'' is defined as ``any portion 
    of a commercial motor vehicle combination * * * used for carrying 
    cargo, including a trailer, semitrailer, or the cargo carrying section 
    of a single unit truck.'' While section 1023 is relatively narrow in 
    scope, section 4006 has very widespread applicability. If, as the WTA 
    contends, vehicles not previously considered to be LCV's are covered by 
    this final rule, it is because of section 4006. This section is also 
    the reason that vehicles are listed in appendix C for Alaska. Thus, 
    vehicles not previously considered LCV's are included in this final 
    rule, because the statute applies to more than just LCV's.
        The ATA expressed concern that the FHWA's attempt to organize the 
    vehicles subject to the freeze into four basic categories requires the 
    FHWA to go beyond the role established for it in the ISTEA. The ATA 
    contends that the ISTEA limits the role of the Secretary to reviewing 
    for accuracy and publishing State information and that the 
    categorization made by the FHWA involves the interpretation of State 
    laws and regulations. Similarly, Alaska commented that the nomenclature 
    used in designating the four basic categories ``is not universally 
    acceptable.'' The categories used in appendix C, as included in the 
    SNPRM, were (1) Rocky Mountain Doubles, (2) Turnpike Doubles, (3) 
    Triples, and (4) Other. These names were chosen in an attempt to 
    describe the vehicles covered by the freeze in terms commonly used in 
    the trucking industry. Since there is no industry-wide or statutory 
    definition for categories 1, 2, or 3, a degree of confusion remained as 
    to just what vehicle combinations were covered, especially by 
    categories 1 and 2.
        The ISTEA required the FHWA to list vehicles by ``configuration 
    type'' (section 1023) or ``specific configuration'' (section 4006). In 
    creating the basic configuration categories used in the NPRM and SNPRM, 
    the FHWA believed it had to go beyond just publishing State-submitted 
    information. For example, many States do not differentiate between a 
    ``Rocky Mountain'' and ``Turnpike'' Double in the statutes or 
    regulations which authorize their operation. Typically, these States 
    allow a truck tractor-semitrailer-trailer, or a truck tractor and two 
    trailing units where each trailing unit can be up to some maximum 
    length. Interpretations were required to develop the maximum parameters 
    that would apply if the State did differentiate by vehicle type.
        The FHWA has re-examined the meaning of ``configuration,'' however, 
    and determined that there is no statutory requirement to classify 
    vehicle combinations according to industry usage.
        In order to reduce confusion and simplify the description of 
    vehicles covered by the freeze, the vehicles described in appendix C of 
    this final rule have therefore been regrouped into three categories: 
    (1) Truck tractor and two trailing units, (2) Truck tractor and three 
    trailing units, and (3) Other. This preserves the freeze required by 
    the ISTEA without limiting the discretion allowed by some States before 
    June 1, 1991.
    
    Vehicles Submitted by States but Excepted From or Not Subject to 
    Section 4006 of the ISTEA
    
        In preparing the March 20, 1992, NPRM and the February 25, 1993, 
    SNPRM, the FHWA decided not to include certain vehicle combinations 
    submitted by the States, which it determined Congress did not intend to 
    include in the ISTEA freeze. No additional information regarding 
    conditions, routes, or authority to operate these vehicles was 
    required. In addition to describing the categories of vehicles proposed 
    for exemption, a detailed listing by State of the vehicles submitted 
    but exempted was contained in the SNPRM.
        In its comments, the ATA urged the FHWA to include in the 
    regulatory language of the final rule the list of exempted vehicles 
    included in the preamble to the SNPRM. The basis for the ATA's 
    suggestion was ``to ensure that only the vehicles intended by Congress 
    are restricted and to help clarify the intent of the restriction for 
    enforcement and judicial purposes.'' The ATA's proposal was to include 
    the list of excepted vehicles in an expanded definition of LCV in the 
    final rule.
        The categories of multiple cargo unit vehicles exempted from 
    coverage by the freeze include: (1) Truck tractor-semitrailer-trailer 
    and truck tractor-semitrailer-semitrailer combinations with a maximum 
    length of the individual cargo units of 28.5 feet or less, (2) 
    conventional automobile and boat transporters with an overall length of 
    65 feet or less, (3) stinger-steered automobile and boat transporters 
    with an overall length of 75 feet or less, (4) truck-trailer and truck-
    semitrailer combinations with an overall length of 65 feet or less, (5) 
    maxi-cubes, (6) most tow trucks with vehicles in tow, and (7) 
    combination vehicles which include a truck tractor containing a 
    dromedary box, deck, or plate, and one semitrailer or trailer. With 
    respect to the dromedary equipped vehicle exclusion, strict 
    interpretation of ISTEA section 4006 would include this equipment under 
    the freeze. By its function, a dromedary box, deck, or plate is a 
    cargo-carrying unit. When combined with a semitrailer, the result is 
    technically a combination with two cargo-carrying units, thus 
    subjecting the combination to the freeze. However, dromedary equipped 
    truck tractors in actual operation on December 1, 1982, are 
    grandfathered under Sec. 658.13(f), causing a combination consisting of 
    one of these units and a semitrailer to be considered as simply a truck 
    tractor-semitrailer under the provisions of part 658. Dromedary 
    equipped semitrailer combinations are a minor segment of the industry 
    which probably escaped the notice of Congress, and which would require 
    a good deal of additional time and effort to list. Should States or 
    carriers try to evade the ISTEA freeze mandate by expanding the size of 
    these unlisted combinations, the FHWA may have to initiate rulemaking 
    to close this loophole.
        The exclusion information is codified by this final rule at 
    Sec. 658.23(b)(1) through (b)(5). The list of exempted vehicles by 
    State included in the SNPRM has not been codified, however, because of 
    the likelihood that it is not a complete list. The original instruction 
    to the States about these vehicles was to submit anything they thought 
    might be covered by the freeze. Since the effect of ATA's comment would 
    be to exempt only those vehicle combinations listed, some States could 
    be penalized in terms of allowing certain vehicles simply because they 
    reviewed the guidelines and made a decision that certain vehicles were 
    not involved in the freeze coverage.
        The definition of LCV used throughout this proceeding is that 
    established in the ISTEA. In the interest of avoiding confusion with 
    respect to terminology, the FHWA will not amend the LCV definition at 
    this time.
    
    Documentation of Actual Operation
    
        Under the terms of ISTEA section 1023, an LCV may continue to 
    operate only if on or before June 1, 1991, the specific configuration 
    was (1) legally allowed in the State and (2) was in actual lawful 
    operation on a regular or periodic basis. Under section 4006, the 
    overall length of two or more cargo-carrying units used in a specific 
    configuration may not exceed the length allowed by State law, and in 
    actual lawful operation on a regular or periodic basis, on or before 
    June 1, 1991. If a specific multi-trailer configuration was authorized 
    by State statute or regulation, but not in actual lawful operation on a 
    regular basis on or before June 1, 1991, it may not now be put into 
    service.
        All of the vehicles listed in appendix C meet the requirements for 
    continued operation set forth in ISTEA sections 1023 and 4006.
        The information on these vehicles which the States supplied in 
    response to the ISTEA, the March 20, 1992, NPRM and the February 25, 
    1993, SNPRM, satisfies the legal requirement for operation, i.e., 
    authorized by State law. In a similar manner, various commenters, 
    responding to a request contained in the SNPRM, have documented the 
    actual operation on a regular or periodic basis of the vehicle 
    combinations listed.
        The SNPRM requested information, from any source, to show the 
    actual operation of vehicles described in appendix C. While a copy of 
    the special permit under which operations occurred was listed as the 
    preferred means of satisfying the documentation requirement, any item 
    which could support operation of these vehicles would be considered as 
    acceptable.
        In an early response to the docket, the ATA expressed concern that 
    the FHWA was placing a ``tremendous burden on State DOT's and the 
    trucking industry to satisfy a totally new requirement in a very short 
    time period.'' The SNPRM allowed for a 45-day comment period with April 
    12, 1993, as the docket closing date. The ATA also stated that ``(i)t 
    is unlikely that two year old copies of the actual permit will be 
    available,'' and that working with the permit issuing offices in each 
    State to locate these records would ``no doubt be a very time consuming 
    and cumbersome process.'' As an alternative, the ATA suggested that the 
    FHWA allow the submission of an affidavit from a carrier and/or State 
    agency to satisfy the documentation requirement, and further that a 
    time extension be granted to allow appropriate review and certification 
    of these documents, if allowed. A request for a time extension for the 
    docket was also received from the WTA and Coastal Chem Sales Company of 
    Cheyenne, Wyoming. The need to accurately comply with the actual 
    operation documentation requirement was given as the reason for the 
    request.
        In its comments, the CRASH stated that the proof requirement 
    contained in the SNPRM was ``far too broad, and (could) easily lead to 
    mistake or fraud.'' That organization argued that anything less than 
    ``verifiable documentary evidence created and dated on or before June 
    1, 1991, specifically detailing the vehicle length, weight, 
    configuration and routes traveled'' would fail to comply with ISTEA 
    requirements.
        In reviewing the time extension requests, the FHWA agreed that more 
    time was needed to help assure that accurate and complete documentation 
    information, including affidavits, was submitted to the docket. On 
    April 14, 1993, a 45-day extension of the comment period, to May 27, 
    1993, was published in the Federal Register at 58 FR 19367. The type of 
    information the CRASH argued the FHWA should require appears to exceed 
    the documentation most States demand of LCV operators. It would distort 
    the purpose of the ISTEA freeze to ban certain vehicles or routes 
    simply because the States lacked the foresight to issue permits that 
    met the maximum possible data requirements of a Federal law not yet 
    enacted.
        An affidavit made by an individual familiar with the issue at hand 
    is both reasonable and within the documentation parameters established 
    by the SNPRM. The authenticity of any document proposed as evidence to 
    support activity occurring over 2\1/2\ years ago could be challenged by 
    any party. Of the possible items of documentation which could be 
    submitted, a notarized affidavit may be the least susceptible to 
    alteration. It represents an individual's witnessed, sworn statement.
        An affidavit could, of course, be fraudulent, and the FHWA would be 
    reluctant to take regulatory action based solely on an affidavit 
    without other support. In fact, however, affidavits are merely one kind 
    of information which the FHWA has combined with other types of 
    documentation to demonstrate the operation of vehicles that State law 
    and/or regulation allows. In addition, section 1023(c) of the ISTEA 
    amended 23 U.S.C. 141(b) by adding at the end the following sentence: 
    ``Each State shall also certify that it is enforcing and complying with 
    the provisions of section 127(d) of this title and section 411(j) of 
    the Surface Transportation Assistance Act of 1982 (49 U.S.C. App. 
    2311(j))'' (emphasis added). Additional discussion of the certification 
    change is contained elsewhere in this document. However, for this 
    discussion the statement means that if a State is found not to be 
    complying with the ISTEA LCV requirements, it will be subject to 
    Federal-aid highway funding sanctions involving millions of dollars 
    annually.
        Documentation of operation of the vehicles listed in appendix C for 
    each State was provided to the docket by the following sources. All 
    original submissions are filed in docket number 92-15.

    cooperative, State DOT
    South Dakota: Four carriers, one shipper, three private fleets, 
    State Trucking Association, State Highway Patrol, State DOT
    Utah: Sixteen carriers, one shipper, three private fleets, one 
    agricultural cooperative, one owner-operator, State Motor Truck 
    Association, State DOT
    Washington: Five carriers, one shipper, two private fleets, one 
    agricultural cooperative, one owner-operator, State DOT
    Wyoming: Six carriers, two shippers, four private fleets, one owner-
    operator, three individuals, State DOT
    
        The following vehicle combinations included in the SNPRM, or 
    comments thereto, have not been included in appendix C for the reasons 
    given.
    
        California: ``Triple,'' including a 28-foot semitrailer, two 28-
    foot trailers, an overall length of 107.4 feet, and a maximum gross 
    vehicle weight of 111,000 pounds. ``Rocky Mountain Double,'' 
    including a 48-foot semitrailer, a 28-foot trailer, an overall 
    length of 93.2 feet, and a maximum gross vehicle weight of 106,850 
    pounds. ``Turnpike Double,'' including a 48-foot semitrailer, a 48-
    foot trailer, an overall length of 116.7 feet, and a maximum gross 
    vehicle weight of 122,650 pounds.
    
        Two permits were issued by the California Department of 
    Transportation (Caltrans) for ``Triples'' at the request of the 
    California legislature in 1971 in order to conduct a test to evaluate 
    the possible allowance of ``Triples'' in California. In 1983, permits 
    were issued to allow the operation of the above described vehicle 
    combinations in order to conduct an over the road test of these 
    vehicles. The State, in its comments, points out that the 1983 tests 
    were conducted, in part, to assist the FHWA in its study of the costs 
    and benefits of a national intercity LCV route network.
        Based on these two occurrences, California claims the right to 
    issue permits for good cause for the future operation of these vehicles 
    up to the limits stated.
        The FHWA has rejected California's claim because it fails to meet 
    the standard for ``regular or periodic'' use established by Congress in 
    writing the ISTEA. According to the Conference Report on the ISTEA 
    (H.R. Conf. Rep. No. 404, 102d Cong., 1st Sess. 314 (1991)), ``Use of 
    an LCV on only one or two occasions pursuant to a special permit would 
    not provide a basis for satisfactorily certifying grandfather rights or 
    operations under this subsection.'' Clearly the California situation 
    falls within the scope of the congressional guidance. ``Triples'' were 
    allowed twice, for very brief periods 12 years apart, the last being 
    more than 10 years ago. ``Turnpike Doubles'' and ``Rocky Mountain 
    Doubles'' were authorized only once, over 10 years ago, during a single 
    5-day period. These occurrences do not constitute ``regular or 
    periodic'' use.
    
        Connecticut: Vehicle and trailer for carrying poles, lumber, 
    piling, or structural units.
    
        No documentation was received in the docket to support the actual 
    operation of this vehicle on or before June 1, 1991. This vehicle was 
    originally included because it appeared to meet the LCV or extra-length 
    multi-unit commercial vehicle requirements. This vehicle is made up of 
    a truck tractor and a dolly unit. Since the weight of a cargo, for 
    example utility poles, is carried partially by the truck tractor and 
    partially by the dolly unit, the argument might be made that this 
    vehicle has two cargo-carrying units.
        In fact, the load and rear dolly combine to create a de facto 
    semitrailer. Truck tractor-semitrailers are not subject to the freeze.
    
        Delaware: Truck tractor-semitrailer-trailer, with a cargo-
    carrying length of 62 feet.
    
        No documentation was received in the docket to support the actual 
    operation of this vehicle on or before June 1, 1991. The initial 
    submission by Delaware, to satisfy the LCV freeze requirements, 
    indicated that the listed combination was allowed by State law wherein 
    each trailing unit could be up to 29 feet long. The 62-foot length was 
    derived by adding 4 feet for interunit spacing to the twin 29-foot 
    dimension. Due to the de-listing of a vehicle combination with twin 29-
    foot units, the maximum length of any one unit in a multi-unit 
    combination vehicle reverts to 28.5 feet, that allowed by the STAA of 
    1982.
    
        Louisiana: ``Rocky Mountain Double-LCV,'' with a cargo- carrying 
    length of 75 feet.
    
        No documentation was received in the docket to support the actual 
    operation of this vehicle on or before June 1, 1991. The initial 
    submission by Louisiana, to satisfy the LCV freeze requirements, 
    indicated the listed combination was allowed by State law wherein each 
    trailing unit could be up to 30 feet long. The 75-foot length was 
    derived by adding the maximum interunit spacing allowed by State 
    regulation of 15 feet to the twin 30-foot dimension. Due to the de-
    listing of a vehicle combination with twin 30-foot units, the maximum 
    length of any one unit in a multi-unit combination vehicle reverts to 
    28.5 feet, that allowed by the STAA of 1982.
    
        New Hampshire: Truck-trailer combination with a cargo-carrying 
    length of 85 feet.
    
        No documentation was received in the docket to support the actual 
    operation of this vehicle on or before June 1, 1991. The initial 
    submission by New Hampshire, to satisfy the LCV freeze requirements, 
    indicated the listed combination was allowed because State law does not 
    prohibit a straight truck of up to 40 feet long from pulling a trailer 
    that may be up to 48 feet long. Due to the de-listing of the described 
    vehicle combination, the maximum cargo-carrying length of any truck-
    trailer combination on NN highways reverts to 58 feet. This length is 
    derived by subtracting 7 feet for the cab from the 65-foot overall 
    length for this combination allowed by this rule without a requirement 
    to document actual operations. Off the NN, the maximum lengths allowed 
    by State law continue to apply.
    
    List of ISTEA Vehicle Operations and Conditions
    
        In addition to the lists of vehicle configurations, the ISTEA also 
    required each State to submit a copy of all its statutes, regulations, 
    limitations, and conditions which apply to the operation of each of the 
    LCV's or extra-length vehicles reported as in use on or before June 1, 
    1991.
        The content of the States' original responses to this request 
    covered the full range of what could be supplied, both in terms of 
    items covered and volume of material. The diversity of the contents of 
    the responses was so great that the FHWA determined that before any 
    list could be finalized, increased uniformity would be necessary. One 
    of the subheadings for each LCV or extra-length vehicle described in 
    the NPRM was ``Operational Conditions.'' The information in the NPRM 
    was taken directly from the initial State responses to the LCV 
    information request contained in the ISTEA, regardless of content. In 
    those cases where another document was referenced, the FHWA attempted 
    to summarize that document. Because of the differences in State-
    provided responses, there was little consistency as to coverage or 
    depth. Therefore, in addition to asking for comments, the NPRM also 
    asked the States and all other sources, including industry trade 
    groups, either to reformat existing information, or to provide new 
    information following a suggested format. Those States which allow 
    LCV's or extra-length vehicles were requested to provide the 
    operational condition information in the following subheadings: WEIGHT, 
    DRIVER, VEHICLE, PERMIT, and ACCESS. 
        The information included in the SNPRM reflected the States' and 
    other responses to the NPRM request.
        The SNPRM included specific vehicle descriptions for 30 States. 
    Comments were received concerning those descriptions for 23 States. The 
    vehicle descriptions included in appendix C to part 658 by this final 
    rule have been modified, where appropriate, by comments received and by 
    the change in categories described earlier. Comments, changes, and 
    corrections made to appendix C information will be discussed by State, 
    by subheadings, in the same order that they appear in appendix C:

    LEGAL CITATIONS:
    OTHER COMMENTS:
    
        Other comments considered, that did not result in a change, will be 
    discussed at the end. Any heading not included in the discussion means 
    that the information included in the SNPRM was accurate, and the same 
    information has been included in appendix C as published by this final 
    rule.
    
    Alaska
    
    OPERATIONAL CONDITIONS:
        WEIGHT: The State DOT commented that the weight restriction 
    discussion in the SNPRM for Alaska should not apply because the section 
    1023 freeze applies only to the Interstate System, and Alaska does not 
    have Interstate System mileage designated under 23 U.S.C. 103, 139(a), 
    or 139(b). The FHWA agrees with this comment. Accordingly, the weight 
    condition for each vehicle described has been revised to indicate that 
    a carrier has to be in compliance with State laws and regulations and 
    does not list maximum weight limit values. In addition, because LCV's, 
    as defined in the ISTEA, do not operate in Alaska due to the lack of 
    Interstate System mileage, the ``LCV'' notation previously included by 
    the combination description has been removed.
        VEHICLE: The State indicated that the hours of operation for three 
    trailing unit combinations are established by permit and not by 
    regulation. Accordingly, this has been removed from the ``VEHICLE'' 
    discussion.
        PERMIT: The SNPRM noted that permits were required for divisible 
    loads. The State commented that this was incorrect. Permits are only 
    required for nondivisible loads.
    OTHER COMMENTS:
        The CRASH stated that Alaska Administrative Permit Manual Section 
    11.6 provides that ``all oversize or overweight vehicles not in convoy 
    shall maintain a minimum distance of 800 to 1,500 feet from any other 
    oversize vehicle or vehicle with load and pilot car traveling in the 
    same direction on the same highway in rural areas.'' Since Alaska is 
    not contiguous to any other State this type of information would be of 
    little use to any out-of-State trucker. Any vehicle requiring a permit 
    would be subject to the Alaska permit rules which would be given to the 
    driver when the permit was obtained. Therefore, in view of its limited 
    usefulness in terms of general information, we will not add this 
    provision to appendix C.
        Section 4006(a) of the ISTEA provides that Alaska ``may allow 
    operation of commercial motor vehicle combinations which were not in 
    actual operation on June 1, 1991, but which were in actual operation 
    prior to July 6, 1991.'' Verification has been furnished that 
    ``Triples'' with trailers not over 45 feet in length were in actual 
    operation under permit prior to July 6, 1991. The CRASH believes that 
    the operation of ``Triples'' after June 1, 1991, was authorized only on 
    an experimental basis as provided in 17 AAC 25.106(b)(4). However, the 
    ISTEA allows the continued operation of any combinations put into 
    service between June 2 and July 5, 1991, without further condition. 
    Therefore, ``Triples'' may continue to operate, as indicated in 
    appendix C.
        The State advised that under Alaska regulations, a truck tractor 
    equipped with a dromedary box is defined as not being cargo carrying. 
    Dromedary boxes do in fact carry cargo. However, for the reasons given 
    above, the FHWA has decided for the time being not to list the cargo-
    carrying length of dromedary tractor-semitrailer combinations.
        The State indicated that an additional route, AK-1 from Palmer-
    Wasilla Highway Junction to Wishbone Hill Coal Access Road, must be 
    added to Alaska's routes chart under the caption for ``Rocky Mountain 
    Double-LCV'' (58 FR 11467) of the SNPRM. However, this is incorrect 
    because the freeze on vehicle length is applicable only on the NN, and 
    this is not an NN route. The State is free to regulate the size and 
    weight of vehicles off the NN as it sees fit.
    
    ARIZONA
    
    LEGAL CITATIONS:
        The CRASH stated that Arizona statute ARS 28-1011.N should not be 
    shown as authority for permitting overweight vehicles on the NN since 
    it only covers the issuance of permits on other than NN routes. We 
    agree, since the provisions of Section 4006 of the ISTEA apply only to 
    vehicles on the NN. Therefore, ARS 28-1011.N has been deleted from the 
    ``Legal Citations'' for Arizona in appendix C.
    OTHER COMMENTS:
        The CRASH stated that the legal size for ``Rocky Mountain Doubles'' 
    is 90 feet, and not 92 feet as shown in proposed appendix C contained 
    in the SNPRM. Arizona statute ARS 28-1011.A provides that the Arizona 
    DOT may issue oversize permits for vehicles exceeding otherwise 
    applicable length limits on the State highway system. Further, the 
    change in categories from those listed in the SNPRM makes this a moot 
    point insofar as the final appendix C is concerned.
        The CRASH stated that the State may not issue ``verbal policy 
    directives'' authorizing overlength vehicles. It adds that the State 
    appears to be violating its own statutes. The question cannot be 
    resolved in this proceeding but the FHWA will investigate the issue in 
    connection with Arizona's certification of compliance with 49 U.S.C. 
    app. 2311(j).
        The CRASH also stated that weight limits for LCV's on US 89A and I-
    15 cannot be determined under ARS 28-1011.N. The FHWA agrees. Since the 
    ISTEA freezes the weight of LCV's only on the Interstate System, we 
    will not further consider weight limits on US 89A. The State indicated 
    that the maximum allowable weight limits for all LCV's on the 
    Interstate System is 111,000 pounds, except for ``Triples,'' which it 
    said are subject to a maximum allowable weight of 123,500 pounds. The 
    111,000-pound maximum weight limits are specifically authorized under 
    ARS 28-1011.M, and higher maximum weights may be authorized under ARS 
    28-1011.A on the State highway system. Since the State indicated that 
    the highest weight authorized for ``Triples'' on or before June 1, 
    1991, was 123,500 pounds, that value is retained in appendix C.
    
    COLORADO
    
    LENGTH OF THE CARGO-CARRYING UNITS:
        Appendix C in the SNPRM showed the cargo-carrying length for 
    ``Rocky Mountain Doubles'' in Colorado as 85 feet, for ``Turnpike 
    Doubles'' 95 feet, for ``Triples'' 95 feet, and for truck-trailer 
    combinations as 78 feet. However, on June 1, 1991, the State actually 
    allowed one of the trailing units in ``Rocky Mountain Doubles'' to be 
    up to 48 feet long and the other up to 28 feet 6 inches long, with not 
    over 15 feet of hitch between the two units, or a total cargo-carrying 
    length of 91.5 feet. The State also allowed ``Turnpike Doubles'' to 
    have two trailers of approximately equal length, not to exceed 48 feet 
    each, with a hitch not to exceed 15 feet in length. The resulting 
    cargo-carrying length becomes 111 feet. Revised appendix C has been 
    changed to reflect these values.
        The State allowed ``Triples'' to have three trailing units, not to 
    exceed 28.5 feet, with a 15-foot hitch between the trailing units. 
    Appendix C has been changed to a cargo-carrying length of 115.5 feet to 
    reflect this.
    OPERATIONAL CONDITIONS:
        PERMIT: The State requested that a new sentence be added after the 
    first sentence under the ``Permit'' provisions for ``Rocky Mountain 
    Doubles'' in appendix C as follows: ``Also, the vehicle must purchase 
    an overweight permit pursuant to C.R.S. 42-4-409(11)(a)(II)(A), (B), or 
    (C), and comply with Rule 4-15 in the rules pertaining to Extra-Legal 
    Vehicles or Loads.'' The State also commented that the time 
    restrictions on the operation of ``Rocky Mountain Doubles'' in the next 
    sentence should be changed from 7 a.m. to 6 a.m. and from 4 p.m. to 3 
    p.m. and that the sentence in parentheses should read as follows: 
    ``('Rocky Mountain' doubles not operating at greater than the legal 
    maximum weight of 80,000 pounds are subject to different hours of 
    operation restrictions. Refer to rules pertaining to the Operation of 
    Longer Vehicle Combinations on Designated State Highway Segments).'' 
    The CRASH said motor carriers that operate ISTEA vehicles must have an 
    established safety program as provided in Chapter 9 of the Colorado 
    Department of Highways Rules and Regulations for Operation of Longer 
    Vehicle Combinations on Designated State Highway Segments. Elements of 
    the program include compliance with minimum safety standards at 8 CCR 
    1507-1; hazardous materials regulations at 8 CCR 1507-7, 8, and 9; 
    Colorado Uniform Motor Vehicle Law, Articles 1 through 4 of Title 42, 
    C.R.S., as amended; and Public Utility Commission's regulations at 4 
    CCR 723-6, 8, 15, 22, and 23. Revised appendix C includes these 
    changes.
    ROUTES:
        Appendix C in the SNPRM indicated routes on which ``Rocky Mountain 
    Doubles'' could travel as ``National Network routes except that LCV's 
    may not operate on I-70 from Exit 90 to Exit 259.'' However, the State 
    indicated that they essentially may operate only on the Interstate 
    System. Appendix C has been amended accordingly.
    LEGAL CITATIONS:
        The State said that in the ``Legal Citations'' for ``Rocky Mountain 
    Doubles,'' 42-4-407(1)(C)(III)(A), should be corrected by changing the 
    capital ``C'' to a small ``c.'' It also said that provisions following 
    this citation should be deleted and the following added: ``LVC's must 
    comply with Longer Vehicle Combination Rules and the Extra-Legal 
    Vehicles or Load Rules. However, when the rules address the same 
    subject, the LVC, since it is operating at greater than 80,000 pounds, 
    must comply with the Extra-Legal Vehicles or Loads Rules. Such rules 
    are: 4-1-2 and 4-1-3 concerning holiday travel restrictions, 4-1-5 
    concerning hours of operation restrictions, 4-8 concerning minimum 
    distance between vehicles and 4-15 concerning maximum allowable gross 
    weight.'' These changes have been made.
    OTHER COMMENTS:
        The State pointed out that no maximum gross weight is shown in 
    connection with the truck-trailer combination listed in appendix C. 
    This is correct because a truck-trailer combination is not an LCV as 
    defined in the ISTEA since it is not a combination of a truck tractor 
    and two or more trailers or semitrailers. Therefore, its maximum weight 
    on the Interstates is not frozen as of June 1, 1991, but remains as 
    provided in 23 U.S.C. 127(a). The listing for this combination has been 
    changed in appendix C by adding ``WEIGHT'' as a separate category under 
    ``Operational Conditions'' and indicating that the vehicle must be in 
    compliance with State laws and regulations.
        The State also noted that ``Rocky Mountain Doubles'' could operate 
    from milepoint 8.9 to milepoint 9.7 on State Highway 133 in Delta. 
    However, as this is not on the Interstate System or the NN, the ISTEA 
    freeze provisions do not apply. Accordingly, the route is not listed in 
    the vehicle descriptions. The CRASH said that prior to June 1, 1991, 
    ``Rocky Mountain Doubles'' could operate on I-70 from the Utah State 
    Line only to State Highway 65 (Exit 49). In fact, the route was 
    extended from State Highway 65 to State Highway 13 (Exit 90) on April 
    5, 1990. Since this was prior to June 1, 1991, ``Rocky Mountain 
    Doubles'' may continue to operate from the Utah State Line to State 
    Highway 13 (Exit 90) after that date.
        The State also commented that the freeze on the operation of LCV's 
    on the Interstate System and the freeze on the operation of CMV's with 
    two or more cargo-carrying units on the NN may create administrative 
    and enforcement problems. However, it also recognized that this arises 
    from the ISTEA and cannot be changed in this proceeding.
    
    FLORIDA
    
    COMBINATION:
        The State commented that Florida law and rules contain no 
    references to ``Rocky Mountain Doubles'' and that all references to 
    them in appendix C should be deleted. The revision of the categories 
    used in appendix C, as presented by this final rule, addresses the 
    State's concern over nomenclature.
    OTHER COMMENTS:
        Florida commented that the 106-foot length previously given for 
    ``Turnpike Doubles,'' now shown for a truck tractor and two trailing 
    unit combination, is incorrect. The maximum length should be 116 feet. 
    The 116-foot dimension is the maximum overall vehicle length 
    established by State regulation. Appendix C is a listing which includes 
    maximum cargo-carrying length. The convention used throughout this 
    rulemaking is that, in the absence of any information to the contrary, 
    cargo-carrying length for a truck tractor combination is the maximum 
    overall length minus 10 feet. Thus, 106 feet remains the cargo-carrying 
    length value for Florida's truck tractor and two trailing unit 
    combination.
        The State also expressed concern over the fact that the vehicles 
    listed for Florida are not considered LCV's as provided in the ISTEA 
    definition, because the route on which they operate, Florida's 
    Turnpike, is not part of the Interstate System. The State made the 
    point that the twin-trailer combinations which operate on the Florida 
    Turnpike match the configuration and weight criteria for LCV's, and 
    only an administrative action, whether or not the Turnpike is part of 
    the Interstate System, keeps them from being designated as such.
        Until the ISTEA was enacted, the meaning of the term LCV differed 
    from one region to another, and sometimes depended on the commodity 
    being transported. By providing a definition of LCV, Congress has 
    provided a basis for describing these combinations on a national basis. 
    Any combination which does not meet all of the criteria, including 
    operation on the Interstate System, is not to be considered an LCV.
    
    IDAHO
    
    OTHER COMMENTS:
        The CRASH stated that the SNPRM omitted the provisions for time-of-
    travel restrictions for overlegal loads published in Idaho 
    Transportation Department Rule 39.C.11.5, and the requirement that an 
    applicant for a permit certify that the load is indivisible. These 
    restrictions apply only to nondivisible loads as indicated in Rule 
    39.C.11.4.c. There are no time-of-day restrictions for Extra-Length 
    Vehicle Combinations operating under permits issued pursuant to Rule 
    39.C.22. The CRASH also indicated that time-of-travel restrictions 
    applied to overweight loads under Rule 39.C.11.5. Although the rule is 
    entitled ``Time of Travel Restrictions for Overlegal Loads,'' the text 
    deals only with ``oversize'' loads. The CRASH said that the SNPRM 
    omitted seasonal weight limits in Rule 39.C.14. The Rule simply 
    provides that such limits will be posted. Therefore, they are in the 
    same category as speed limits or other general restrictions that all 
    vehicles must observe.
        The ``Dromedary tractor semitrailer'' combination listed in the 
    SNPRM has been removed from appendix C due to the exclusion of such 
    combinations from the list as discussed earlier. The ``Dromedary 
    tractor semitrailer trailer'' combination has also been removed from 
    appendix C due to the dromedary equipment exclusion. This vehicle is 
    covered by the listing for the truck tractor and two trailing unit 
    LCV's.
    
    INDIANA
    
    OPERATIONAL CONDITIONS:
        VEHICLE: The CRASH commented that the SNPRM omitted several 
    equipment requirements for all LCV combinations including those for 
    emergency equipment, safety chains, lights, reflectors, and for three 
    trailing unit combinations, spray-suppressant mud flaps. All of these 
    items have been added to appendix C.
        PERMIT: The CRASH indicated that maximum speed and the State wind 
    operational restrictions were omitted from the permit discussion. These 
    have been added.
    OTHER COMMENTS:
        The CRASH also commented that the State 3-inch sway limitation was 
    not included in the SNPRM. The requirement was, in fact, included in 
    the SNPRM and has been retained in this final rule.
    
    KANSAS
    
    MAXIMUM ALLOWABLE GROSS WEIGHT:
        The State commented that the maximum allowable gross weight listed 
    for ``Triples'' in the SNPRM was incorrectly listed as 110,000 pounds 
    and that the value should instead be 120,000 pounds. The 110,000-pound 
    limit applies only to three trailing unit operations on I-70 between 
    the Colorado State Line and Goodland. The Kansas Turnpike allows these 
    combinations to operate at 120,000 pounds. This change has been made in 
    appendix C.
    OPERATIONAL CONDITIONS:
        Under the Operational Conditions described for ``Triple--LCV'' in 
    the SNPRM, the phrase at the beginning of the section ``called special 
    vehicle combinations (SVC's) in Kansas,'' has been deleted in appendix 
    C at the request of the State. The term ``SVC'' applies only to 
    operations on I-70 between the Colorado State Line and Goodland. It 
    does not apply on the Turnpike.
        DRIVER: At the request of the State, the wording has been corrected 
    to accurately differentiate between SVC operations and operations on 
    the Turnpike.
        VEHICLE: The CRASH commented that vehicle equipment requirements 
    concerning lateral movement in the travel lane and anti-spray devices 
    were not included in the SNPRM for SVC operations. Both items are now 
    included in appendix C.
        PERMIT: The CRASH commented that the permit discussion for SVC 
    operations did not include the requirement to have insurance coverage 
    of certain amounts. Appendix C has been changed to reflect the 
    requirement to have insurance coverage, however, the amounts are not 
    included in appendix C. The amount of insurance coverage is not an item 
    that is directly related to the size and weight of LCV's.
        ACCESS: SVC access was not included in the SNPRM because SVC 
    operations were not included. Appendix C now includes SVC access 
    provisions according to comments provided by the State.
    ROUTES:
        I-70 in Western Kansas: Kansas allows SVC's on the short segment of 
    I-70 from Goodland to the Colorado State line. Kansas submitted this 
    information and it was published in the NPRM. The FHWA subsequently 
    learned that SVC operations began on that route only on May 31, 1991, 
    the day before the June 1 freeze date.
        The ISTEA provides that LCV's (including SVC's) must have operated 
    ``on a regular or periodic basis'' on or before June 1, 1991 (23 U.S.C. 
    127(d)(1)(A)). According to the ISTEA conference report:
    
        To be considered ``regular or periodic'' use, operations must 
    have occurred at recurring intervals over a period of time. 
    Moreover, periodic operations must have occurred on an intermittent 
    but consistent basis. Use of an LCV on only one or two occasions 
    pursuant to a special permit would not provide a basis for 
    satisfactorily certifying grandfather rights or operations * * * . 
    (H.R. Rep. No. 404, 102d Cong., 1st Sess., at 314 (1991))
    
    Because SVC operations on I-70 did not appear to be ``regular or 
    periodic'' by this standard, the FHWA revised the SNPRM to remove the 
    Goodland segment from the list of authorized Kansas LCV routes.
        Thirty-seven commenters discussed this subject, and all of them 
    favored restoration of the I-70 route. Yellow Corporation, the parent 
    company of Yellow Freight, explained in detail how the problem arose. 
    Yellow Freight uses a hub and spoke system. The company commented that 
    ``(w)here distances between hubs do not allow for the journey to be 
    made within the ten-hour federal drivers hours of service limit, Yellow 
    Freight has established driver relay facilities (where) * * * drivers * 
    * * are changed, with the equipment moving on to meet customer service 
    demands.'' Yellow Freight has for 25 years maintained a driver relay 
    facility at Goodland which serves vehicles moving between its Kansas 
    City and Denver hubs. ``Linehaul drivers leave Kansas City westbound to 
    Goodland, layover and return eastbound the next day. Goodland-domiciled 
    linehaul drivers operate a turn between Goodland and the Denver hub.''
        Colorado authorized triple-trailer and other large combinations in 
    1989. Unlike competitors with facilities in eastern Colorado, Yellow 
    Freight was unable to use these vehicles between Goodland and Denver 
    because Kansas did not allow them on I-70. Rather than move its relay 
    facility into Colorado or forgo the economic advantages of ``Triples,'' 
    Yellow Freight asked Kansas in September 1989, to allow SVC's on
    I-70 between Goodland and the Colorado line. The Kansas Department of 
    Transportation (KDOT) announced a rulemaking proposal in January 1990, 
    that would have allowed ``Triples'' on all Kansas Interstates. The 
    Kansas Railroad Association (KRA) responded by having a bill to ban 
    ``Triples'' introduced in the legislature; the KDOT withdrew its 
    proposal. Yellow Freight and the KRA negotiated a compromise which, 
    among other things, allowed triple-trailer combinations on the Goodland 
    segment of I-70. The bill was approved on April 12, 1990, and SVC 
    regulations to implement it were promulgated on March 4, 1991. Yellow 
    Freight ran one ``Triple'' on May 31, 1991, and a second on June 1.
        Both Yellow Freight and the KDOT place much of the blame for delays 
    in issuing the permits required to start
    I-70 operations on the FHWA's failure to clarify its position on the 
    State's grandfather rights in a timely fashion. The FHWA and a number 
    of States--not including Kansas--had long disagreed on the question of 
    whether LCV operations were legitimately grandfathered. One of the 
    purposes of the LCV freeze was to resolve these disputes by ratifying 
    actual operations allowed by State law on June 1, 1991. The KDOT's 
    announced intention to allow SVC's on I-70 was one more indication of 
    the rapid spread of LCV's in States west of the Mississippi. Because of 
    the desirability of a uniform policy toward all States that allowed LCV 
    operations, the FHWA did not immediately address the question of 
    Kansas' grandfather rights. However, on April 8, 1991, just over a 
    month after the KDOT's regulations authorizing SVC permits became 
    effective, the FHWA asked for an opinion by the Kansas Attorney General 
    (AG). The KDOT requested the opinion on April 26, 1991, and the AG 
    replied on May 30, 1991, that the State's grandfather rights were broad 
    enough to encompass SVC operations on I-70. Since the issue here is 
    ``regular or periodic'' operations, it would serve no purpose to 
    discuss the AG's grandfather claims. The KDOT quickly issued an annual 
    SVC permit to Yellow Freight and operations began the following day.
        The State's regulatory process was not completed until March 4, 
    1991, and the Kansas AG required more than a month to respond to the 
    KDOT's request for an opinion. The FHWA had no part in these delays. It 
    is true, however, that the KDOT made a good faith effort to satisfy the 
    FHWA's legal concerns and postponed the start of SVC operations on I-70 
    until the deadline included in the draft ISTEA legislation had nearly 
    passed. We do not wish to penalize Kansas simply for cooperating with 
    the FHWA.
        Yellow Freight asserted that ``(a)s originally drafted, the Federal 
    LCV freeze date would have been April 1, 1991. Senator Dole's office 
    intervened to move that federal freeze date to June 1, 1991, 
    specifically to accommodate the Goodland triples route.''
        In its comments in response to the SNPRM, the ATA said:
    
        ATA was deeply involved in the Congressional deliberations 
    leading to the LCV freeze. It is our understanding that the language 
    in the Conference report was designed to preclude establishing LCV 
    operations based on single trip permits for infrequent truck 
    movements. Therefore one or two movements of heavy machinery by a 
    specialized carrier would not create ``grandfathered rights.''
        ATA understands that for Kansas, a single trip permit would 
    normally be issued for ``occasional use'' purposes. It is clear that 
    the intent of the (SVC) permit was for multiple trip purposes and 
    not occasional ``one or two trips.'' The permit had been applied for 
    long before the freeze language was proposed. It was only a matter 
    of timing that so few trips were made.
    
        There is nothing in the ISTEA legislative history that clarifies 
    the meaning of ``regular or periodic basis,'' but the ATA's 
    interpretation is plausible, especially in view of the Caltrans' 
    response to the SNPRM. The Caltrans stated that it
    
        [I]ssued two permits, at the request of the California 
    Legislature, allowing two vehicle combinations with three 26.5-foot 
    trailers to operate from October 27 to November 5, 1971. These 
    vehicle combinations had an overall length of 94.25 feet with gross 
    vehicle weights of 76,800 pounds and 90,000 pounds. The 1971 permits 
    were issued to gather information on truck tractor and triple 
    trailer combination operations. The information was used to consider 
    whether triple combination operations should be allowed in 
    California.
    
        In 1983, the Caltrans issued permits for operational tests of (1) a 
    111,000-pound ``Triple'' (28-foot trailers) between October 24-28; (2) 
    a 106,850-pound ``Rocky Mountain Double'' (48-foot semitrailer, 28-foot 
    pup) between November 7-10; and (3) a 122,650-pound ``Turnpike Double'' 
    (two 48-foot trailers) between November 14-18. The Caltrans argued that
    
        California retains the right to issue an extralegal permit for 
    good cause to operate a divisible combination of vehicles exceeding 
    the maximum size or weight limits with specific guidance provided by 
    the California Legislature.
    
        The brief tests performed by California one and two decades ago, 
    which never resulted in the authorization of LCV's, are certainly among 
    the minimal operations that the requirement for ``regular or periodic'' 
    use was intended to exclude. The FHWA has therefore declined to list 
    these vehicles in appendix C.
        Kansas and Yellow Freight, on the other hand, clearly expected 
    LCV's to use I-70 routinely and for years to come, and made elaborate 
    preparations on that basis. In addition, the KDOT's efforts to 
    cooperate with the FHWA delayed the issuance of the first permits, 
    which would otherwise have been available in March 1991. On balance, 
    the FHWA believes that the SVC operations on I-70 satisfy the statutory 
    standard. The Goodland route has therefore been restored to appendix C.
        The CRASH commented on the accuracy of the lists of routes 
    available to the different vehicle combinations. Appendix C now 
    reflects the proper route listings. Due to the SVC and Turnpike 
    operations, the truck tractor and three trailing unit combination does 
    have more route mileage available to it than do two trailing unit 
    combinations. The new route lists show that I-70 between the Colorado 
    State Line and Goodland is available only to SVC's with three trailing 
    units and not to LCV combinations with two trailing units.
    LEGAL CITATIONS:
        One change has been made at the request of the State. KSA-8-1915 
    has been moved from the list of applicable statutes for two trailing 
    unit combinations to the list for three trailing unit combinations.
    
    MASSACHUSETTS
    
    LENGTH OF THE CARGO-CARRYING UNITS:
        The CRASH commented that the cargo-carrying length listed in the 
    SNPRM for the ``Turnpike Double--LCV'' was incorrectly listed as 114 
    feet. This figure is the overall length previously allowed for this 
    configuration. Applying the convention for determining cargo-carrying 
    length used throughout this rulemaking, 10 feet will be deducted for 
    the tractor. The cargo-carrying length now shown in appendix C for the 
    truck tractor and two trailing unit combination is 104 feet.
    OPERATIONAL CONDITIONS:
        VEHICLE: The CRASH pointed out two vehicle requirements missing 
    from the SNPRM, one concerning emergency equipment and the other 
    concerning passing requirements. Both provisions have been added to 
    appendix C.
        PERMIT: The CRASH commented that the SNPRM did not include the 
    requirement to have insurance coverage of certain amounts. Appendix C 
    has been changed to reflect the requirement to have insurance coverage, 
    however, the amounts are not included in appendix C. The amount of 
    insurance coverage is not an item that is directly related to the size 
    and weight of LCV's.
    
    MICHIGAN
    
    COMBINATION:
        The State commented that the vehicle in question is a truck 
    tractor-semitrailer-trailer where one of the cargo units exceeds 28.5 
    feet in length. Michigan statutes allow an overall length for the two 
    trailers, as measured from the front of the first trailer to the rear 
    of the second trailer, of 58 feet, including the load. This vehicle 
    configuration was excluded from the original listing of LCV's in the 
    NPRM. The exclusion was based on a definition of excepted combination 
    used in the NPRM (57 FR 9901, March 20, 1992) as follows:
    
        Truck tractor-semitrailer-semitrailer and truck tractor-
    semitrailer-trailer configurations with a maximum length of cargo-
    carrying units of 62 feet or less are subject to the provisions of 
    23 CFR part 658. These are the twin 28-foot units authorized by the 
    STAA, and the 28-foot B-train doubles authorized as specialized 
    equipment by the FHWA.
    
        Michigan contends that the vehicle was correctly excepted in the 
    NPRM since the Michigan vehicle clearly fell within the length 
    parameters of non-LCV vehicles.
        The exclusion by the FHWA in the NPRM was erroneous. The vehicle 
    was included in the SNPRM and is now in the final rule since it can 
    consist of a truck tractor and two trailing units and can carry more 
    than 80,000 pounds on the Interstate System.
        The State also commented that the ``Rocky Mountain Double--LCV'' 
    description in the SNPRM was inappropriate for the vehicle in operation 
    in Michigan. The revised combination categories now used in appendix C 
    has alleviated this concern.
    MAXIMUM ALLOWABLE GROSS WEIGHT:
        The State commented that the table listing vehicle combinations 
    subject to the ISTEA, illustrating a Michigan vehicle listed under 
    ``Rocky Mountain Doubles'' with a 128,000-pound maximum gross weight, 
    was inappropriate. Michigan, the State argued, is an axle weight State 
    with a grandfather provision and maximum gross weights are determined 
    based on axle and axle group weight limits. Therefore, it would be 
    inappropriate to specify a single maximum gross weight for Michigan. 
    The FHWA does not agree. The table and text have been revised to show a 
    maximum allowable gross weight of 154,000 pounds. The 154,000-pound 
    figure was determined from the maximum axle weight limits for an 11-
    axle vehicle (the maximum number of axles allowed under State law) with 
    optimum axle spacing and with a combined cargo-carrying box length of 
    58 feet. Vehicles with fewer axles or less than optimum axle spacing 
    will have a lower allowable gross weight based on State requirements.
    OPERATIONAL CONDITIONS:
        VEHICLE: Michigan commented that certain statements included in the 
    SNPRM did not apply to the vehicle in question. These statements 
    concerned (1) the overall length of a truck and trailer or semitrailer 
    combination and (2) operational hours for certain vehicles hauling 
    hazardous materials. The appropriate sentences have been removed from 
    the text.
        ACCESS: The State commented that ``Access'' should read ``all 
    designated State highways.'' This change has been made.
    ROUTES:
        In response to a comment by the State, the ``ROUTES'' description 
    has been changed to indicate that all Interstate and designated State 
    highways are open to these vehicles.
    
    MISSISSIPPI
    
    COMBINATION:
        The State commented that a CMV with two cargo units, subject to the 
    freeze requirements of section 4006 of the ISTEA, originally submitted 
    by the State and included in the NPRM, was inadvertently left out of 
    the SNPRM. The vehicle, which is subject to the freeze because the 
    trailing units may each be up to 30 feet long, has been included in 
    appendix C with the operational information listed as supplied by the 
    State.
    
    MISSOURI
    
    OTHER COMMENTS:
        The CRASH claimed that an error in available routes had been made 
    in the SNPRM, and that the SNPRM did not include several items that 
    pertain to permitted loads. The CRASH not only questioned the 
    availability of several Interstate routes in the Kansas City 
    metropolitan area, but also the availability of I-44 in southwest 
    Missouri. It stated that ``the only National Network route from which 
    LCV's can enter Missouri is I-70 in Kansas.'' Several NN routes in 
    Kansas and Oklahoma come up to the Missouri State Line. LCV's are 
    allowed to operate on I-44 in Oklahoma, thus making I-44 available to 
    enter Missouri. In Kansas, LCV's have access to the northeastern end of 
    the Kansas Turnpike, over any route within a 20-mile radius. Within 
    that 20-mile radius in Kansas, several Interstate and other highways, 
    which prior to passage of the ISTEA were designated as Federal-aid 
    Primary highways, come up to the Missouri State Line. LCV's may use any 
    of these routes to reach terminals in Missouri which fall within a 20-
    mile band of the Kansas State Line.
        The CRASH indicated that the State indivisible load requirement had 
    been omitted from the SNPRM. In addition, the CRASH contends that 
    several operational requirements were also omitted, including those 
    involving time-of-day restrictions, weather requirements, oversize load 
    signs, speed, tractor unit power, and the need for insurance. The State 
    responded that routine overdimension and overweight special permit 
    issuance in Missouri is made in accordance with State Rule 7 CSR 10-
    2.010 (based on Section 304.200, Revised Statutes of Missouri 1992), 
    which provides for a uniform administration of large and heavy loads.
        Although the rule (7 CSR 10-2.010) as originally promulgated by the 
    Missouri Highway and Transportation Commission disallows routing 
    reducible loads (except for farm products) under permit, in July 1986 
    the State's chief engineer, exercising other authority within the rule, 
    authorized travel for multi-unit LCV's carrying reducible loads. To 
    quote Rule 7 CSR 10-2.010:
    
        [T]he chief engineer of the State Department of Highways and 
    Transportation, for good cause shown and when the public safety or 
    public interest so justifies, shall issue special permits for 
    vehicles or equipment exceeding the limitations on width, length, 
    height, and weight herein specified * * *.
    
        It was determined to be in the public interest to allow LCV 
    operation to relieve economic stress and give motor carriers the 
    incentive to retain terminals in Missouri. Missouri would then be more 
    competitive with adjacent western States which allow LCV operations. 
    The operation of LCV's has gone without reported incident, according to 
    annual documented safety assessments made by the Missouri Highway and 
    Transportation Department, the Missouri State Highway Patrol, the 
    Kansas City Public Works Department, and the Kansas City Police 
    Department.
        In response to other items listed, the State made the point that 
    Missouri Revised Statute Sec. 304.200 (1992) gives the chief engineer 
    significant latitude in allowing the operation of LCV's, and that 
    several items including speed and weather restrictions are conditions 
    of the permit issued for the operation of LCV's.
    
    MONTANA
    
    OPERATIONAL CONDITIONS:
        PERMIT: The CRASH said that a provision requiring carriers 
    operating vehicles subject to the ISTEA freeze to have ``public 
    liability and property damage insurance for the protection of the 
    traveling public as a whole'' was omitted from appendix C. Appendix C 
    has been changed to reflect the requirement to have insurance coverage; 
    however, the amounts are not included. The amount of insurance coverage 
    is not an item that is directly related to the size and weight of 
    LCV's.
    OTHER COMMENTS:
        The CRASH said that Chapter 672 of the Montana Session Laws of 
    1991, which amended Montana Code Annotated (MCA) section 61-10-124, 
    increased the length of Turnpike Doubles from 95 to 100 feet in length 
    effective January 1, 1992, and, therefore, the cargo-carrying length in 
    appendix C should be based on the shorter length. This is incorrect. 
    Before the change, section 61-10-124 read as follows:
    
        A term permit may be issued for any combination of vehicles that 
    exceeds 95 feet in length but does not exceed 100 feet in length, * 
    * *.
    
    After the 1992 change, it read as follows, with the additional word 
    underlined.
    
        A term permit may be issued for any combination of vehicles that 
    exceeds 95 feet in length but does not exceed 100 feet in 
    combination length, * * *.
    
        The amendment clarified but did not substantially change the law; 
    term permits could be issued for ``Turnpike Doubles'' not more than 100 
    feet long on June 1, 1991.
    
    NEVADA
    
    OPERATIONAL CONDITIONS:
        VEHICLE: The CRASH said that the Nevada Department of 
    Transportation Rules and Regulations in Sections 484.400, 484.405(4), 
    484.425, 484.430, 408.100-4, and 408.100-6(a), primarily dealing with 
    emergency and safety equipment, should be added to the Nevada 
    provisions in appendix C. We concur, and this has been done.
    OTHER COMMENTS:
        While appendix C has been changed to reflect the requirement to 
    have insurance coverage, the amounts are not included in appendix C. 
    The amount of insurance coverage is not an item that is directly 
    related to the size and weight of LCV's.
    
    NEW MEXICO
    
    LENGTH OF THE CARGO-CARRYING UNITS:
        The cargo-carrying length restriction does not apply to two 
    trailing unit combinations. The length of each trailing unit is limited 
    to 28.5 feet. This describes a two trailing unit vehicle whose 
    operation is guaranteed by the STAA regardless of inter-unit spacing. 
    As long as each trailing unit is 28.5 feet long or less, cargo-carrying 
    length is not restricted. This combination is listed as an LCV because 
    it can exceed the 80,000-pound threshold established in the 
    congressional definition. New Mexico has a grandfathered gross weight 
    limit of 86,400 pounds.
    
    NEW YORK
    
    COMBINATION:
        The State submitted an additional vehicle for inclusion in appendix 
    C. It is an STAA Double (twin 28.5-foot units) hauling up to 100,000 
    pounds under a State DOT permit. As this combination may operate on NN 
    highways in New York, appendix C has been amended to account for its 
    operation. This combination was inadvertently omitted by the State DOT 
    in its previous LCV submissions and docket comments.
    OPERATIONAL CONDITIONS:
        VEHICLE: The CRASH commented that several items were omitted from 
    the ``VEHICLE'' discussion in the SNPRM, including the need to carry 
    emergency equipment, mud flaps, safety chains, and a tractor 
    certification identification number. All of these items are now 
    included in appendix C.
        The discussion under DRIVER, VEHICLE, and PERMIT has been revised 
    to note the fact that the New York State Thruway Authority, in addition 
    to its responsibility for the tolled sections of Interstate routes 87, 
    87/287, 90, 95, and 190 (the original Thruway mainline between New York 
    City and Pennsylvania along with the Berkshire, New England, and 
    Niagara sections), now also has jurisdiction over the full length of I-
    84, and that portion of I-287 between Thruway exit 8 and I-95. These 
    latter two sections remain toll-free, and the operating rules that 
    apply are the same as those in effect on all other highways in the 
    State that are under the jurisdiction of the New York State DOT.
    OTHER COMMENTS:
        The CRASH also sought to include the insurance requirements and the 
    amounts. While appendix C has been changed to reflect the requirement 
    to have insurance coverage, the amounts are not included in appendix C. 
    The amount of insurance coverage is not an item that is directly 
    related to the size and weight of LCV's.
        In addition to the added combination discussed earlier, the State 
    submitted a second vehicle for inclusion in appendix C. It is a 
    combination which uses twin 28.5-foot units to carry nondivisible 
    loads. This vehicle has not been included as nondivisible loads moving 
    under permit are not subject to the freeze.
    
    OKLAHOMA
    
    LENGTH OF THE CARGO-CARRYING UNITS:
        The cargo-carrying unit length for the two trailing unit 
    combination has been listed in this final rule at 110 feet. This length 
    was determined after further review of docket comments submitted by the 
    CRASH, actual operation documentation submitted by various carriers, 
    and the appropriate State statutes and regulations. The composite of 
    the information available leads the FHWA to conclude that on or before 
    June 1, 1991, the longest legally allowed multi-unit combination 
    vehicle in regular or periodic use in the State consisted of a truck 
    tractor-semitrailer-trailer, wherein each of the trailing units was 53 
    feet long. Combining twin 53-foot units with a 4-foot drawbar results 
    in the 110-foot cargo-carrying length. In the NPRM the cargo-carrying 
    length listed for both the ``Rocky Mountain'' and ``Turnpike'' Doubles 
    was 123 feet. In the SNPRM, 123 feet was again listed for the 
    ``Turnpike'' Double. The 123-foot distance was the result of combining 
    a 4-foot drawbar with twin 59-foot 6-inch units.
        For purposes of establishing a cargo-carrying length subject to the 
    freeze provisions of the ISTEA, the State incorrectly interpreted 
    relevant provisions of the STAA of 1982. It appears the State reasoned 
    that since the STAA required (1) that all States allow truck tractor-
    semitrailer-trailer ``Doubles'' combinations, and (2) that Oklahoma 
    must allow a 59-foot 6-inch semitrailer to meet the grandfather 
    provisions of the STAA (53 FR 2599, Jan. 29, 1988), it follows that 
    Oklahoma must therefore allow twin 59-foot 6-inch units to operate as 
    part of a multi-unit combination vehicle.
        While the STAA does require all States to allow ``Doubles,'' the 
    only applicable length requirement is that each State must allow at 
    least 28.5-foot trailing units. The allowance of any longer unit is at 
    a State's discretion within the parameters established by this final 
    rule. The grandfathered semitrailer length applies only for truck 
    tractor-semitrailer combinations. The STAA requires that each State 
    continue to allow trailers or semitrailers of such dimensions as those 
    that were in actual and lawful use in the State on December 1, 1982. 
    The January 1988 rulemaking referred to earlier established that length 
    as 59 feet 6 inches for Oklahoma.
        For purposes of establishing a cargo-carrying length subject to the 
    freeze provisions of the ISTEA, a determination must be made as to the 
    unit lengths comprising combination vehicles authorized by State 
    statute or regulation and in actual operation on a regular or periodic 
    basis on or before June 1, 1991. Re-examination of all submitted 
    material and docket comments resulted in the 110-foot length.
    
    OREGON
    
    LENGTH OF THE CARGO-CARRYING UNITS:
        The Oregon Department of Transportation (ODOT) commented that 
    overall length requirements for three trailing unit combinations have a 
    significant impact on public safety and must be retained. The ODOT also 
    said that the length of tractors in combination with three trailing 
    units is not a uniform 10 feet long but can range from 9 to 14 feet.
        The freeze does not affect the authority of the ODOT to enforce an 
    overall length limit on triple-trailer combinations. However, it does 
    limit the overall length of the cargo-carrying units to what was 
    authorized and in use on or before June 1, 1991. Although the comment 
    does not specifically indicate that 9-foot-long tractors were in use 
    with ``Triples'' on or before June 1, 1991, we assume that was the 
    intent. Therefore, appendix C has been changed to correct the cargo-
    carrying length of three trailing unit combinations from 95 to 96 feet.
    OPERATIONAL CONDITIONS:
        VEHICLE: The CRASH commented that ORS 818.150(5) provides that any 
    towed vehicles in a combination must be equipped with safety chains or 
    cables to prevent the towbar from dropping to the ground in the event 
    the coupling fails. The chains or cables must have sufficient strength 
    to control the towed vehicle in the event the coupling device fails and 
    must be attached with no more slack than necessary to permit proper 
    turning. However, this requirement does not apply to a fifth-wheel 
    coupling if the upper and lower halves of the fifth wheel must be 
    manually released before they can be separated. Appendix C has been 
    amended accordingly.
    ROUTES:
        The ODOT indicated that there is no direct relationship between 
    approved routes for three trailing unit combinations and the NN 
    highways. The connection is that the freeze applies only on NN 
    highways. Consequently, truck tractor and three trailing unit 
    combinations may not operate with more than 96 feet of cargo-carrying 
    length on routes shown in appendix C. The State is free to regulate the 
    use of triple-trailer combinations as it sees fit on other highways.
    OTHER COMMENTS:
        The CRASH also indicated that officials who issue permits may 
    require the applicant to furnish public liability and property damage 
    insurance and establish that the permit vehicle will stay on the right 
    side of the centerline at all times. We do not regard these conditions 
    to be the type which must be published in appendix C since the State 
    has discretion whether or not to apply them.
        The ODOT asked for a definition of terms and vehicles used in FHWA 
    rulemakings but did not cite any specific items that should be defined. 
    We are unaware of any items that should be defined or that could be 
    defined without affording interested persons the opportunity to comment 
    on the proposed definitions.
    
    SOUTH DAKOTA
    
    OPERATIONAL CONDITIONS:
        VEHICLE: The CRASH said that provisions relating to public 
    liability insurance, the amount of offtracking allowed and the entering 
    of the dimensions used to calculate the offtracking on the permit form 
    should be included in appendix C. We concur, and appendix C has been 
    modified accordingly.
    OTHER COMMENTS:
        The State said that the maximum weight limit for ``Rocky Mountain 
    Doubles'' is not ``129K'' as shown on the table at 58 FR 11465-11466 of 
    the SNPRM but is the ``Uncapped Federal Bridge Formula.'' For LCV's the 
    maximum allowable weight is capped at what was allowed and in actual 
    operation on June 1, 1991. Based on the information submitted by the 
    State, a ``Turnpike Double,'' which must also comply with the Federal 
    Bridge formula, is limited to a maximum of 129,000 pounds. The 
    recategorization of the vehicles subject to the LCV freeze has adopted 
    the 129,000-pound value for the ``Turnpike Double'' as the maximum for 
    a truck tractor and two trailing units.
        The State showed the length of the road tractor-trailer-trailer 
    combination as 80 feet. However, this is the overall length. When the 
    length determination in the SNPRM is used, the cargo-carrying length is 
    the overall length minus 10 feet for the length of the tractor. 
    Therefore, the cargo-carrying length of this combination is shown in 
    appendix C as 70 feet.
        The State asked for certain additions and deletions to appendix C. 
    The recategorization of the vehicles subject to the LCV freeze 
    accounted for most of the changes suggested by the State. The 
    descriptions for South Dakota, which now appear in appendix C, take 
    into account the comments made by the State.
    
    UTAH
    
    OPERATIONAL CONDITIONS:
        VEHICLE: The CRASH said that Utah Regulations for Legal and 
    Permitted Vehicles, sections 400.2(8), (12), and (14) pertaining to 
    sway of multiple-trailer vehicles, following distance, and insurance 
    requirements, respectively, should be reflected in appendix C. We 
    concur, and appendix C has been amended accordingly.
    ROUTES:
        The State clarified the basis for delineating vehicles allowed to 
    operate on divided or nondivided highways from overall length to length 
    of cargo-carrying units. This reformatting did not change the lengths 
    allowed, but simply re-stated the lengths to match the language of the 
    ISTEA.
    LEGAL CITATIONS:
        The State also corrected the legal citation for truck tractor and 
    two trailing unit combinations and indicated that those for ``Triples'' 
    should be the same. These changes have been made.
    
    WASHINGTON
    
    COMBINATION:
        The State indicated that the listing in the SNPRM for ``Dump truck 
    with pup trailers'' should be changed to ``Truck and trailer.'' We 
    agree, and this change has been made in appendix C.
    OTHER COMMENTS:
        The State indicated that the listing in the SNPRM of ``truck 
    tractor with dromedary box-semitrailer-trailer'' should be changed to 
    read ``truck tractor carrying a freight compartment no longer than 
    eight feet-semitrailer-semitrailer or full trailer.'' As indicated 
    previously, we have decided for the time being not to list dromedary 
    equipment separately. This vehicle is therefore covered by the listing 
    for the truck tractor and two trailing unit LCV which also has a cargo-
    carrying length of 68 feet.
        The State also commented that the length of the cargo-carrying 
    units for ``Rocky Mountain Doubles'' should indicate that the 68-foot 
    length includes the load. We disagree. The ISTEA limited the length of 
    cargo-carrying units, not loads. If the State wants to prohibit, or 
    allow, cargo overhangs over that length, it is free to do so since it 
    retains all the authority it possessed prior to the ISTEA to regulate 
    cargo overhangs.
    
    WYOMING
    
        Many of the comments made by the WTA and the State DOT involved 
    allowable lengths and weights for what previously had been 
    differentiated as ``Rocky Mountain'' and ``Turnpike'' Doubles. The 
    recategorization into truck tractor and two trailing units now used in 
    appendix C, has accommodated many of these comments.
    COMBINATION:
        On or before June 1, 1991, Wyoming only allowed combination 
    vehicles consisting of not more than three single vehicles. This 
    precluded the operation of triple-trailer combinations which consist of 
    four single vehicles--a truck tractor, a semitrailer, and two trailers. 
    A provision of the ISTEA, in effect, gave the State until the next 
    general election day following enactment (November 3, 1992) to decide 
    whether to allow ``Triples.'' A Statewide referendum to allow their use 
    was defeated in the November 3, 1992, election and, as a result, the 
    ISTEA bars the use of ``Triples'' in Wyoming.
    LENGTH OF THE CARGO-CARRYING UNITS:
        Provisions relating to the length of a semitrailer in a truck 
    tractor-semitrailer combination will not be added to appendix C since 
    this vehicle is not subject to the ISTEA freeze. The State DOT argued 
    that its 60-foot semitrailer length limit would apply to automobile and 
    boat transporters with no overall length limit. This is not consistent 
    with the Federal requirement that States must allow standard automobile 
    and boat transporters to have a minimum overall length of 65 feet (75 
    feet if stinger-steered), with no specific limit on the length of the 
    semitrailer. However, application of the State rule does not conflict 
    with the Federal requirement since, as a practical matter, it only 
    applies to vehicles longer than 65 or 75 feet. Such longer combinations 
    would be subject to the ISTEA freeze. As a result, appendix C has been 
    changed to list the overall length of auto and boat transporters, since 
    cargo is typically carried on a headrack the same length as the 
    tractor, in addition to the cargo on the trailer.
    OTHER COMMENTS:
        The WTA said that a truck-trailer combination falls under the 
    definition of ``any other combination of vehicles'' in Wyoming law and, 
    therefore, is limited to a total overall length of 85 feet with no 
    single unit exceeding 60 feet. While the combination is limited to 85 
    feet, the 60-foot limit applies only to semitrailers in a truck 
    tractor-semitrailer combination. The showing of 78 feet for the length 
    of the cargo-carrying units was based on allowing 7 feet for cab 
    length.
        The WTA said that it could not understand why the cargo-carrying 
    length of saddlemount combinations was shown in the SNPRM as 75 feet. 
    Under Wyoming law it would be considered as ``any other combination'' 
    subject to an overall length of 85 feet. We agree. Since the tractor in 
    a saddlemount combination is part of the cargo being transported, we 
    have changed the length of the cargo-carrying units for this 
    combination to 85 feet.
    
    TOW TRUCK OPERATIONS
    
        The nature of the service provided by wreckers or tow trucks is 
    such that these vehicles need to have immediate access to all roads in 
    a State to remove disabled or abandoned, as well as accident-damaged, 
    vehicles. They are, to that extent, emergency vehicles. There is no 
    evidence that Congress intended to include these operations under the 
    freeze restrictions. Therefore, the FHWA proposed in the SNPRM to 
    exclude emergency towing operations from any of the freeze provisions 
    proposed in appendix C. Comments on this issue were received from the 
    California and Washington DOT's and the California Highway Patrol.
        Both of the California agencies recommended that proposed 23 CFR 
    658.23(b)(5), which would allow tow trucks and vehicles in tow to 
    operate on the NN without regard to the freeze on length, be amended to 
    require a State permit to operate overlength. This is unnecessary since 
    23 CFR 658.23(b)(5) merely means that they are not limited to whatever 
    length was allowed and in use on June 1, 1991. Since they also are not 
    STAA vehicles, the State may regulate their length in any manner it 
    sees fit, including the requirement for a permit, if it wishes.
        The Washington DOT asked if tow truck operations are restricted to 
    the length and weight in effect on June 1, 1991. As stated in the 
    SNPRM, emergency towing operations are excluded from any of the freeze 
    provisions in appendix C. However, the proposed provisions in paragraph 
    (b) of 23 CFR 658.23 only excluded tow trucks from the length 
    provisions of appendix C. In order to fully exclude emergency towing 
    operations from any of the provisions contained in new 23 CFR 658.23, 
    the underlined phrase in paragraph (a)(1) has been added:
    
        (a)(1) Except as otherwise provided in this section and except 
    for tow trucks with vehicles in tow, * * *.
    
        Also, in paragraph (b)(5) ``with'' has been substituted for 
    ``and.''
    
    Pole Trailers
    
        In the SNPRM the FHWA proposed to list, as the authorized length 
    for expandable trailers used for carrying poles, logs or pipe, etc. 
    (pole trailers), the lengths allowed by State law, even if these limits 
    refer to the cargo rather than the vehicle itself.
        Only five sets of comments were received which specifically 
    addressed the issue of pole trailers. The South Dakota DOT supported 
    the position that the State-allowed length of the cargo should be 
    considered the cargo-carrying length of the unit. The State added that 
    the FHWA should establish a national cargo overhang policy similar to 
    that in effect for automobile and boat transporters; that is, 3 feet in 
    front and 4 feet to the rear of the vehicle. The Pennsylvania DOT 
    commented that its special length limitation (70 feet) for any 
    combination transporting nondivisible articles has been in place for 
    over 20 years, and that it should be listed as Pennsylvania's length 
    for these vehicles. The California Highway Patrol provided that State's 
    applicable length limits for pole or log trailers. Taking a different 
    tack, both the ATA and the WTA stated in their comments that pole 
    trailers should not be considered or regulated as LCV's. The ATA stated 
    that the ``FHWA is incorrect in believing that establishing length 
    limits for pole trailers is consistent with the purpose of section 4006 
    of ISTEA.'' In addition to echoing the ATA's comment, the WTA went on 
    to state that the FHWA's proposal with regard to regulating pole 
    trailers as an LCV, ``does not recognize that timber harvesters do not 
    cut logs in the same lengths all the time. Utility poles transported by 
    telephone and power companies are not the same length and neither are 
    the joints of pipe used in oil well drilling, pipe line construction 
    and water and sewer line repair and construction.''
        The FHWA has re-examined this issue. In the SNPRM, the FHWA 
    admitted that the statutory language concerning the freeze is not 
    readily applicable to such vehicles. The discussion of pole trailers 
    and the inclusion of these vehicles in the SNPRM was based on an 
    interpretation that the two cross-members on which the cargo rests 
    constitute individual cargo-carrying units for purposes of section 4006 
    of the ISTEA. That argument is difficult to maintain. In fact, the 
    hitch, the load, and rear dolly combine to create a de facto 
    semitrailer. The FHWA has decided not to include these vehicles in 
    appendix C, as truck tractor-semitrailers are not subject to the 
    requirements of the freeze. Two separate pole trailers pulled by a 
    tractor, however, must comply with section 4006.
    
    Further Restrictions on ISTEA Vehicles
    
        The ISTEA provides that States may further restrict, or even 
    prohibit, the operation of LCV's or CMV's with two or more cargo-
    carrying units after June 1, 1991. Such restrictions, however, must be 
    consistent with sections 411, 412, and 416(a) of the STAA. This means 
    that States may not prohibit twin trailer combinations with trailers 
    not over 28 feet long (28.5 feet if grandfathered) from operating on 
    the NN or reasonable access routes. States may not restrict the width 
    of vehicles on the NN or reasonable access routes to less than 102 
    inches or the metric equivalent, 102.36 inches.
        A State must notify the Secretary within 30 days after the 
    imposition of further restrictions or prohibitions on the operation of 
    LCV's or CMV's with two or more cargo-carrying units. The FHWA does not 
    have approval authority over any additional restrictions a State may 
    impose, but is required to publish such restrictions in the Federal 
    Register. The FHWA may require further information or clarification 
    before publishing the restrictions in the Federal Register.
        No additional comments were received on this issue in response to 
    the SNPRM. The proposed regulatory language in the SNPRM directly 
    reflected congressional intent as expressed in the ISTEA. That language 
    has been adopted unchanged by this final rule in Sec. 658.23(e).
    
    Minor Adjustments to Listed Information
    
        Sections 1023 and 4006 of the ISTEA allow States to make minor 
    adjustments of a temporary and emergency nature which will relax route 
    designations and vehicle operating restrictions in effect on June 1, 
    1991. They also direct the Secretary to issue regulations establishing 
    criteria for the States to follow in making such adjustments.
        Minor adjustments must be both temporary and caused by an 
    emergency. According to the Conference Report on the ISTEA (H.R. Conf. 
    Rep. No. 404, 102d Cong., 1st Sess. 314 (1991)), such adjustments are 
    intended to be temporary and limited, e.g., a bridge failure that would 
    require the rerouting of ISTEA vehicles to highways where they would 
    otherwise be prohibited. Since it is impossible to foresee all types of 
    emergencies that might necessitate a minor adjustment, and it is not 
    the intent of the FHWA to establish a burdensome reporting requirement, 
    the proposed regulation would require a State to report the details of 
    an adjustment only if the duration was expected to exceed 30 days. 
    Emergency adjustments with a duration of 30 days or less would not be 
    reported to the FHWA.
        The NPRM proposed to cap the duration of minor adjustments at 1 
    year. Adjustments lasting more than 1 year would not be considered to 
    be of a temporary or emergency nature. Minor adjustments for the same 
    emergency would not be permitted to be broken into periods of less than 
    1 year to extend the emergency for a period longer than that. 
    Similarly, an emergency would not be permitted to be broken into 30-day 
    or shorter periods to avoid reporting. The FHWA re-examined the issue 
    in light of the comments received to the NPRM docket. Subsequently, the 
    SNPRM removed the NPRM's 1-year maximum duration for a minor 
    adjustment, but clearly spelled out that the FHWA must approve any 
    minor adjustments which exceed 30 days. The SNPRM proposal also clearly 
    spelled out that rejection of a State's request would cause the 
    immediate reimposition of freeze restrictions, with failure to do so 
    putting a State at risk of a funding penalty pursuant to 23 U.S.C. 141.
        Two sets of comments to the SNPRM addressed the issue, those of the 
    CRASH and those of the Advocates For Highway and Auto Safety 
    (Advocates). Both organizations objected to the removal of the original 
    1-year time limit. They feared that under the SNPRM States would be 
    allowed to detour LCV's onto highways less capable of safely 
    accommodating these vehicles for unspecified, indefinite lengths of 
    time. The Advocates also objected to the SNPRM proposal because
    
        It fails to provide any criteria for the states to use in 
    choosing alternate routes. The agency (FHWA) simply asserts that it 
    will exercise its discretion to review and approve or disapprove any 
    state's request for an LCV routing adjustment.
    
    It argues that the FHWA is reserving for itself a power to make 
    decisions on an important issue without publicly available guidelines 
    which have been developed through a rulemaking process.
        The criteria represented in the final rule by Sec. 658.23(c) are 
    necessarily general and rely on the review-and-approval nature of the 
    Federal-State relationship.
        It is not practical to develop specific criteria to evaluate 
    requests which might originate for any number of reasons. However, to 
    allay the concerns of both the CRASH and Advocates--that minor 
    adjustments, insofar as alternate routes are concerned, will result in 
    LCV's temporarily operating on highways perceived to be less safe--this 
    final rule includes additional guidance in selecting alternate routes. 
    Section 658.23(c) now provides that in selecting alternate routes, 
    States should, to the extent possible, select routes with geometric and 
    pavement design features equivalent to those of the highway segment 
    which is temporarily unavailable. In addition, each request involving 
    an alternate route should include a discussion of what steps the State 
    will take to mitigate any operational and/or safety problems that may 
    develop.
        The operating philosophy of the FHWA with respect to State issues 
    has always been that of individual office autonomy within broad 
    national guidelines. The Division Office of Motor Carriers within each 
    State is in the best position to evaluate requests involving truck 
    issues in the State. However, in order to assure that a degree of 
    uniformity is applied to such requests, the Regional Office of Motor 
    Carriers must be consulted before a decision is made on a State's 
    request. On issues which involve alternate routes for LCV's, the final 
    rule directs the Division Office of Motor Carriers to coordinate with 
    the Division Administrator before consulting with the Regional Office.
    
    Definition of Nondivisible Loads
    
    Background
    
        The definition of a nondivisible vehicle or load included in the 
    NPRM was criticized by many commenters, and the following revised 
    definition was therefore proposed in the SNPRM:
    
        Nondivisible vehicle or load. As used in this part, 
    ``nondivisible'' means any vehicle or load exceeding applicable 
    length or weight limits which cannot readily be separated into 
    smaller vehicles or loads that comply with such limits without:
        (1) Compromising the intended use of the vehicle,
        (2) Destroying the value of the load, or
        (3) Using expert knowledge or specially designed tools. The 
    intended use of a vehicle would be compromised if separating it into 
    smaller units would make it unable to perform the function for which 
    it was designed. The value of a load would be destroyed if 
    separating it into smaller units would make the load unusable for 
    its intended purpose. Expert knowledge means familiarity with 
    procedures required to dismantle and reassemble a load which are 
    beyond the job requirements typically associated with positions in 
    the motor carrier industry. Specially designed tools means equipment 
    designed and manufactured only for use with the load in question. A 
    State may treat a sealed containerized load moving in international 
    commerce as a nondivisible load.
    
        Many of those who responded to the SNPRM discussed nondivisible 
    loads, but a number of comments suggested that the scope of the 
    definition requires clarification. The definition adopted here (and the 
    others already codified in 23 CFR 658.5) apply, like the ISTEA freeze 
    itself, to the same highways and vehicle characteristics as the 
    underlying Federal law. The following paragraphs explain that principle 
    in more detail.
        Weight: As a condition of receiving Federal-aid funds, States are 
    required to enforce Federal weight limits (23 U.S.C. 127) on the 
    Interstate System and on routes providing reasonable access to and from 
    the Interstate. The penalty for failure to do so is the withholding of 
    a State's National Highway System (NHS) apportionment. A State may set 
    any weight limit it wishes on other highways, though many have 
    voluntarily adopted Interstate limits for all roads. States are 
    therefore required to use the FHWA's definition only when considering 
    whether to issue a nondivisible load permit allowing an overweight 
    vehicle to operate on the Interstate System and roads providing 
    reasonable access to and from the Interstate.
        Length: Federal laws relating to vehicle length (49 U.S.C. app. 
    2311 and 23 CFR 658.13, 658.23) apply to the NN of highways--see 
    appendix A to part 658--and routes providing reasonable access to and 
    from the NN (49 U.S.C. app. 2312 and 23 CFR 658.19). The Interstate is 
    part of the larger NN, and reasonable access rights extend the reach of 
    Federal size laws beyond the NN itself. In contrast to Federal weight 
    law, these provisions and the implementing regulations preempt 
    conflicting State laws or regulations.
        As a practical matter, the FHWA definition of a nondivisible load 
    will rarely be applied to cargo length because it does not cover 
    straight trucks or single-trailer combinations. It covers only loads on 
    vehicles (1) operating on the NN, and routes providing reasonable 
    access to and from the NN, (2) which have two or more cargo-carrying 
    units, and (3) when the overall length from the front of the first to 
    the rear of the last cargo-carrying unit exceeds the longest such 
    length in actual legal operation for a specific configuration on or 
    before June 1, 1991. There are very few single loads that rest 
    simultaneously on the bed of a straight truck and on a trailer, or on 
    two or more trailers. And even in those cases, the definition would not 
    apply unless the total cargo box length were greater than that allowed 
    by the State in 1991. The definition will apply more often to loads, 
    like entire buildings, that are moved on a series of dollies, each of 
    which is a single cargo-carrying unit. There has been virtually no 
    controversy about these loads, and we expect little in the future.
        Width: Federal width law (49 U.S.C. app. 2316 and 23 CFR 658.15), 
    like the length requirements, applies on the NN and reasonable access 
    routes, and it preempts conflicting State laws or regulations. However, 
    the definition of a nondivisible load adopted by this rule does not 
    apply to an overwidth vehicle because Federal law provides that States 
    may issue permits to motor vehicles more than 102 inches wide without 
    regard to divisibility or nondivisibility (49 U.S.C. app. 2316(c)).
        Height: The FHWA has no authority to regulate vehicle height; there 
    is no Federal law on this subject.
    
    Comments to the Docket
    
        Containers: The SNPRM proposed to allow States to treat containers 
    moving in international commerce as nondivisible loads. Responses were 
    about equally divided. Three State transportation departments favored 
    the proposal, while two States, the ATA, and the Advocates opposed it.
        Missouri said that ``(u)niformity among States to issue overweight 
    permits for containerized loads in excess of 80,000 pounds gross weight 
    would be a giant accomplishment.''
        Connecticut suggested that States be required to treat sealed 
    containerized loads moving in international commerce as nondivisible, 
    subject to maximum dimensions and weights it did not specify. Florida 
    went even further, pointing out that
    
    no justification is presented in the SNPRM for not affording 
    identical containerized loads in domestic commerce a benefit being 
    afforded such containers in international commerce. Therefore, it is 
    proposed that the final rule make no reference to either 
    international or domestic commerce and the statement in question 
    should be revised to read: A State may treat a sealed containerized 
    load as a nondivisible load.
    
        On the other hand, the Washington State Patrol strongly disagreed 
    with the proposal.
    
        If that were allowed, the industry could load any container to 
    whatever weight, claim its (sic) moving in international commerce 
    and obtain an overweight permit, without regard to axle, gross 
    weight or bridge formula requirements * * *.
        During a recent ``Container Weight'' study, conducted by the 
    Washington State Patrol, it was shown that of the 3,100 vehicles 
    transporting containers, which exceeded the legal weight limits, all 
    but one could be transported legally by using vehicles with the 
    proper number of axles and axle spacings.
    
    The Washington State Patrol concluded that ``(t)he proposal * * * 
    appears to be in conflict with the `Intermodal Safe Container 
    Transportation Act of 1992' * * *.''
        Similarly, the Washington DOT argued that ``(r)ather than stating a 
    policy that the FHWA is ambivalent about whether the states allow 
    containerized cargo to be treated as non-divisible, it would seem 
    better to encourage a national policy that they are not. This would 
    alleviate competition on this point among ports to make their services 
    more amenable to haulers and shippers.'' South Dakota contended that 
    ``(j)ust because the container is `sealed' or is `moving in 
    international commerce' should not preclude a loaded container from 
    meeting the same size and weight requirements which exists for a load 
    which is loaded in a container, such as a truck box, not `sealed' and 
    not `moving in international commerce.'''
        The ATA recommended that the proposal to allow containers to be 
    treated as nondivisible loads be dropped and that the issue be 
    addressed in the rulemaking to implement the Intermodal Safe Container 
    Transportation Act.
        The Advocates argued that the FHWA had ``openly contravened 
    Congressional intent'' expressed in section 4006 of the ISTEA ``by 
    explicitly endorsing the prospective regular issuance of such permits 
    for any `sealed containerized cargo in international commerce.'''
        FHWA Response: The FHWA agrees that there is a serious question 
    whether the proposal to allow States to treat containers in 
    international commerce as nondivisible loads is consistent with the 
    Intermodal Safe Container Transportation Act of 1992 (Safe Container 
    Act) (Pub. L. 102-548, 106 Stat. 3646, partly codified at 49 U.S.C. 
    508).
        Briefly, the Safe Container Act requires the party tendering a 
    loaded intermodal container or trailer with a cargo weight in excess of 
    10,000 pounds to provide the initial carrier a written certification of 
    the cargo weight and a reasonable description of the contents. Each 
    carrier in the intermodal chain is required to transmit the 
    certification to the next carrier. Motor carriers are prohibited from 
    hauling loaded intermodal containers or trailers subject to the Safe 
    Container Act without receiving a certification. It is also illegal to 
    coerce a motor carrier to haul such a container or trailer (1) without 
    a certification or (2) when the certified weight would make the 
    combination vehicle exceed applicable State weight limits. There are 
    two statutory options if State enforcement personnel discover an 
    overweight tractor-chassis-intermodal container (or tractor-intermodal 
    semitrailer) combination which is on the highway because the motor 
    carrier relied on a false or erroneous certified weight. First, the 
    State is authorized to assess the overweight fine against the initial 
    tenderer and to impound the container or trailer until that party or 
    the beneficial owner of the cargo has paid the fine. Second, if the 
    State fines the motor carrier instead of trying to collect from the 
    shipper or beneficial owner, the motor carrier has a lien on the 
    contents of the container or trailer equal to the amount of the fine 
    imposed and any additional costs incurred in the incident until it 
    receives payment from the tenderer or beneficial owner. If payment is 
    not made within a reasonable time, the carrier may sell the contents to 
    satisfy the lien. The FHWA's proposed regulations to implement the Safe 
    Container Act were published on July 14, 1993, at 58 FR 37895.
        The Safe Container Act imposes administrative requirements and 
    costs on tens of thousands of intermodal shippers around the world, and 
    on the international transportation system, in part to reduce the 
    number of overweight containers operating on the Nation's highways. The 
    Safe Container Act is designed to give U.S. motor carriers enough 
    information about the weight and cargo characteristics of intermodal 
    containers and trailers to enable them to decide whether a particular 
    vehicle can be transported without violating State weight limits. If 
    States were allowed to continue routinely to issue nondivisible load 
    permits for overweight containers, some of the essential purposes of 
    the Safe Container Act would appear to be compromised. There would be 
    little incentive for shippers to load intermodal containers or trailers 
    with U.S. weight limits in mind, little if any reduction in the number 
    of overweight vehicles (even though a permit makes them legal), and 
    little reduction in pavement and bridge damage. Many of the expected 
    benefits of the Safe Container Act would be lost, and the regulatory 
    burdens it entails for shippers and carriers would be pointless, if the 
    FHWA adopted the rule on containers proposed in the SNPRM. The FHWA has 
    therefore decided not to promulgate a final rule dealing with 
    containers, but to treat this subject in a separate notice of proposed 
    rulemaking where the issue can be examined more explicitly and in 
    greater detail. In the meantime, the FHWA's previous policy will remain 
    in effect: the States may continue to issue nondivisible load permits 
    to containers moving in international commerce.
        Expert Knowledge or Specially Designed Tools: Many of the comments 
    focused on the third test for nondivisibility proposed in the SNPRM. If 
    ``expert knowledge or specially designed tools'' were required to 
    dismantle a load, it would be considered nondivisible. Most of the 
    comments were critical.
        The Pennsylvania Department of Transportation found the test to be
        (1) Vague,
        (2) Impractical to measure or verify,
        (3) Subject to manipulation by industry,
        (4) Subject to subjective factors other than the vehicle or load 
    itself, such as driver knowledge of cargo,
        (5) Subject to varying interpretation, and
        (6) In reality, a restatement of the initial economic criterion 
    that was deleted from this latest rulemaking * * * .
        The members of the Specialized Carriers & Rigging Association 
    (SCRA) often move loads that would qualify as nondivisible by any 
    definition. The SCRA noted that the definition proposed by the SNPRM 
    explained expert knowledge as familiarity with procedures required to 
    dismantle and reassemble a load which are ``beyond the job requirements 
    typically associated with positions in the motor carrier industry.'' 
    The Association argued that because highly specialized skills are 
    typically associated with positions in its segment of the motor carrier 
    industry, the definition would make it impossible for special carriers 
    and riggers to obtain nondivisible load permits.
        The Alaska Department of Transportation and Public Facilities also 
    commented that ``expert knowledge'' means very different things in 
    different parts of the industry. It concluded that ``(s)ome further 
    work needs to be done on this definition.''
        The Caltrans commented that, ``(w)hatever definition is finally 
    promulgated, Caltrans is totally opposed to the provisions concerning 
    expert knowledge and specially designed tools.''
        FHWA Response: The FHWA agrees that a test based on ``expert 
    knowledge or specially designed tools'' is too complicated and 
    ambiguous to be effective. It has therefore been replaced with a test 
    based on the time required to divide a load. This general approach was 
    suggested by the Oregon DOT in response to the NPRM. The full 
    definition adopted by this rule is as follows:
        Nondivisible load or vehicle.
        (1) As used in this part, ``nondivisible'' means any load or 
    vehicle exceeding applicable length or weight limits which, if 
    separated into smaller loads or vehicles, would:
        (i) Compromise the intended use of the vehicle, i.e., make it 
    unable to perform the function for which it was intended;
        (ii) Destroy the value of the load or vehicle, i.e., make it 
    unusable for its intended purpose; or
        (iii) Require more than 8 workhours to dismantle using appropriate 
    equipment. The applicant for a nondivisible load permit has the burden 
    of proof as to the number of workhours required to dismantle the load.
        (2) A State may treat emergency response vehicles and casks 
    designed and used for the transport of spent nuclear materials as 
    nondivisible vehicles or loads.
        The first two tests proposed in the SNPRM, and adopted here as 
    paragraphs (1)(i) and (1)(ii), have elicited little comment and no 
    controversy. These standards are appropriate but very stringent. The 
    FHWA believes there are loads that could be divided without literally 
    destroying their value, but only after unreasonable delay and expense 
    to the shipper and motor carrier; the States should be allowed to issue 
    nondivisible load permits in those cases. As the Pennsylvania DOT 
    recognized, this is essentially an ``economic criterion.'' Our earlier 
    proposals to codify this idea would have allowed nondivisible load 
    permits if dismantling the load imposed ``significant additional costs 
    on the shipper or motor carrier'' (NPRM) or required ``expert knowledge 
    or specially designed tools'' (SNPRM). The final rule uses 8 workhours, 
    i.e., a full working day, as a proxy for nondivisibility. The number of 
    workhours required by the rule is the same no matter how many people 
    are involved; for example, if one person working 8 hours, 2 people 
    working 4 hours each, or 4 people working 2 hours apiece, could not 
    dismantle the load, it would be nondivisible. Most loads that require 
    more than one full workday to dismantle, using appropriate equipment, 
    probably were not designed to be taken apart after leaving the factory. 
    We believe Congress intended to allow the use of nondivisible load 
    permits for cargoes which are theoretically divisible, but so tightly 
    integrated that they cannot be dismantled without excessive cost and 
    delay. On the other hand, the definition sets a standard high enough to 
    keep easily divided overweight machinery and equipment off the highway.
        The definition adopted today as paragraph (1)(iii) is more 
    objective than that proposed in the NPRM and less confusing than the 
    amended version included in the SNPRM. It remains complex, however, and 
    disagreements between enforcement officers, motor carriers, and 
    shippers are likely. The rule does not specify how State officials are 
    to determine the length of time required to break down a given load. 
    Manufacturers may sometimes provide the necessary information. The 
    motor carrier itself may have reliable data if it has previously 
    dismantled such cargoes. The rule does not require a carrier or shipper 
    to demonstrate that a given load cannot be broken down in less than 8 
    workhours, but it would not prohibit a State from requiring such a 
    demonstration either. Enforcement officials may be able to work out 
    other reliable methods in cooperation with motor carriers. Paragraph 
    (1)(iii) requires that ``appropriate equipment'' be used in an effort 
    to dismantle a cargo. The number of workers involved and the type of 
    equipment used will depend on the load to be moved. A State is not 
    required to grant a permit in any case, and it would certainly be 
    reasonable to deny a permit to a carrier or shipper which makes a 
    perfunctory or deliberately inadequate effort to dismantle a load 
    within 8 workhours.
        The FHWA intends to allow the States some latitude in implementing 
    the definition, unless indications of nonenforcement or abuse appear.
        Overweight and Overwidth Vehicles: In many cases, nondivisible load 
    permits are likely to be requested for loads which are both overweight 
    and overwidth. The South Dakota DOT favored the definition of a 
    nondivisible load adopted by the Western Association of State Highway 
    Officials (WASHTO), which includes the following:
    
        Portions of a load can be detached and reloaded on the same 
    hauling unit provided that the separate pieces are necessary to the 
    operation of the machine or equipment which is being hauled, if the 
    arrangement does not exceed permittable limits.
    
    The State explained how this definition would work in case of an 
    overweight, overwidth load.
    
        For example, suppose that a ten foot wide crawler tractor with a 
    fourteen foot wide dozer is to be moved. This load can be moved two 
    ways, overweight and fourteen feet wide with the dozer and ten feet 
    wide without the dozer. Clearly the safest way to move the load 
    would be legal weight and ten feet wide but separating the dozer 
    from the crawler tractor destroys the unit for its intended use and 
    it requires expert knowledge to take the dozer off.
    
        FHWA Response: The State has misread the FHWA's proposed 
    definition. Although a bulldozer might be temporarily ``unusable for 
    its intended purpose'' without a blade, that phrase merely clarifies 
    the term ``destroy the value of the load.'' Removing the blade 
    certainly would not destroy the value of the bulldozer. The ``expert 
    knowledge'' test has been eliminated, but it is unclear whether a blade 
    would require more than 8 workhours to remove.
        The flaw in the WASHTO definition is that it allows the separate 
    pieces of an allegedly nondivisible load to be reloaded onto the same 
    vehicle. That defeats the purpose of such a provision, which is to hold 
    down vehicle weights in order to protect the public investment in roads 
    and bridges. The WASHTO definition simply allows a divisible load 
    permit to masquerade as a nondivisible load permit. That is 
    unacceptable.
        Overwidth Vehicles: The WTA described a related, but different 
    situation:
    
        FHWA seems to assume that all overlength (and over-width) loads 
    are also overweight. Much of the equipment used in agriculture is 
    oversize, but not overweight. Allowing the removal of a portion of 
    this type of machinery such as tires and allowing it to be carried 
    on the same trailer is clearly in the public interest, especially 
    when in all respects, the machinery is otherwise eligible for a 
    nondivisible load permit. Requiring a second vehicle to haul the 
    removed part(s) is not smart economics.
    
        FHWA Response: If a piece of farm machinery is overwidth but not 
    overweight, the State may either issue an overwidth permit, make the 
    permit conditional upon the removal of tires but allow them to be 
    carried on the same trailer, or deny a permit. These options are 
    entirely within the discretion of the State. If farm machinery is 
    neither overwidth nor overweight, the question of divisibility would 
    not arise unless two or more cargo-carrying units were needed to 
    transport it, certainly a rare occurrence.
        California Policy: The California Highway Patrol also argued that 
    ``there are incidents involving the transportation of some nondivisible 
    loads, when more than one unit is loaded, (and) can be transported 
    safely. To qualify, loads would have to be oversize, rather than 
    overweight in nature. California permit policy allows the 
    transportation of multiple nondivisible pieces together, provided 
    sufficient supporting justification is given.'' The Caltrans asked for 
    a definition that allows this kind of flexibility.
        FHWA Response: States may allow several nondivisible overwidth 
    loads on the same vehicle, as long as the normal weight limits are 
    observed. That appears to be what California authorizes. As mentioned 
    above, Federal law gives the States great discretion in issuing permits 
    for overwidth loads. There would also be no conflict with Federal 
    regulations if a State allowed more than one overlength nondivisible 
    load to be carried on a single trailer vehicle--assuming the vehicle 
    was not overweight--because the FHWA's definition of a nondivisible 
    load applies only to overlength nondivisible loads carried on two or 
    more cargo-carrying units.
        Safety: The Wyoming DOT, the WTA, and Black Hills Trucking, Inc., 
    referred to Rocky Mountain Prestress, Inc., v. Leno Menghini et al., 
    No. C79-057B, an unreported 1979 Wyoming Federal district court 
    decision, in support of the proposition that safety should be 
    considered in any definition of nondivisible loads. Rocky Mountain 
    Prestress manufactured concrete panels that were to be mounted, two at 
    a time, on A-frame trailers and transported from Denver to Casper for 
    use in construction projects. Wyoming law allowed special permits for 
    overweight ``indivisible loads,'' but the Highway Department rejected 
    plaintiff's application on the ground that two panels were a divisible 
    load. Plaintiff sued the Chief Engineer of the Department, arguing 
    among other things that Wyoming's permit law violated the Commerce 
    Clause of the Constitution. The court held the law constitutional, but 
    found that it had been applied in an arbitrary and capricious manner 
    which impermissibly burdened interstate commerce. The court explained 
    that:
    
        Our conclusion is buttressed by the admission of the Defendants 
    that heavy equipment which is being carried by trailer qualifies as 
    an indivisible load even though the parts thereof may be easily 
    dismantled. Such an approach to granting overweight permits 
    signifies that the State Highway Department has previously, as they 
    must in this case, considered circumstances other than the mere 
    physical divisibility of the goods in transit.
    * * * * *
        We would also observe that forestry goods, baled hay and sugar 
    beets are statutory exceptions to the mandated weight limits. The 
    special interest group exceptions in the Wyoming statutes 
    discriminate against the Plaintiff and others similarly situated who 
    may be equally deserving of exceptions from the weight limitation in 
    view of the safety and economic factors involved. * * *
        * * * [T]he State's desire to protect its highways has been 
    severely diluted by the discriminatory granting of overweight 
    permits to special interest groups, as well as by the routine 
    issuance of such permits based on an indivisible load regulatory 
    provision that we believe was arbitrarily and capriciously applied 
    to the Plaintiff.
    
        FHWA Response: The court concluded that ``the `A' frame is the 
    safest * * * mode of transportation for loading and shipping panels,'' 
    but its evidence on that point was meager. The issue of safe 
    transportation of concrete panels was discussed at some length in the 
    SNPRM (see 58 FR 11455-11457). As we noted there, a single panel, 
    mounted horizontally, would improve the vehicle's braking capability 
    and reduce its susceptibility to side winds. Two such panels obviously 
    constitute a divisible load, and a ``safety'' rationale for doubling 
    the weight of a divisible load is not persuasive.
        Black Hills Trucking now contends that one panel cannot be carried 
    horizontally because it ``is not constructed to stand up to forces 
    coming through its sides,'' or vertically ``because it is not heavy 
    enough in proportion to the `sail' area exposed to side winds which 
    destabilize the load.'' The apparent fragility of these concrete panels 
    does not make two of them any less divisible. Furthermore, the Great 
    Plains experience winds high enough to overturn tractor trailer 
    combinations and double-stack container trains. The interests of safety 
    are better served by halting trucking operations under those conditions 
    than by doubling the weight of the cargo in an effort to anchor the 
    vehicle.
        The Rocky Mountain Prestress decision is not binding on the FHWA. 
    To the extent this rule requires Wyoming to adopt and enforce a new 
    definition for purposes of issuing nondivisible load overweight permits 
    for the Interstate System, it is no longer binding on the State either. 
    The 1979 decision was based upon the State's arbitrary and capricious 
    administration of its own permit law, in particular its failure to 
    apply that law consistently to all motor carriers and commodities. At 
    the time, there was no Federal law on nondivisible loads. Congress 
    enacted nondivisible load provisions for vehicle weight in 1982 and for 
    vehicle length in 1991. Proposed regulations to implement that 
    authority have been subjected to extensive comment and discussion in 
    this rulemaking. Wyoming, like the other States, will be required to 
    adopt the new definition for Interstate operations. That definition 
    will result in greatly increased nationwide uniformity in the treatment 
    of nondivisible loads. Wyoming will have no more administrative 
    discretion than any other State. A judicial challenge to the FHWA's 
    definition of a nondivisible load would therefore confront a legal and 
    factual situation completely different from that which existed in 1979.
        Emergency Vehicles: Section 1023(e)(1) of the ISTEA prohibited the 
    FHWA from penalizing States that allow emergency vehicles to use the 
    Interstate at weights in excess of Federal axle and Bridge Formula 
    limits. The exemption was in effect for 2 years after the date of 
    enactment of the ISTEA and expired on December 18, 1993. Section 
    1023(e) also required a study of State laws and permit practices to 
    determine whether statutory changes were needed to accommodate 
    emergency vehicles.
        To carry out the study, the FHWA requested comments on a variety of 
    questions (57 FR 46941, October 13, 1992). The information submitted 
    indicated that most fire trucks exceed the Federal single- and/or 
    tandem-axle weight limits (20,000 and 34,000 pounds, respectively). 
    These vehicles are rarely short enough to violate the Bridge Formula, 
    however, and almost all of them have gross weights under 80,000 pounds. 
    Technological developments in the manufacturing sector combined with 
    the equipment preferences of fire departments are driving up the size 
    and, especially, the weight of fire trucks. On the other hand, tandem 
    and tridem axles are not favored because they reduce the 
    maneuverability these vehicles need to reach burning buildings. Some 
    States exempt fire equipment from normal weight limits, and others 
    issue blanket overweight permits. The Caltrans reached a compromise 
    with fire officials that will require the latter to observe specific 
    axle limits for various types of vehicles and to make purchasing 
    decisions accordingly.
        The U.S. DOT's report was transmitted to Congress on September 7, 
    1993. It recommended that Congress take no further action because the 
    matter could be resolved by an FHWA policy statement. On November 9, 
    1993, the Federal Highway Administrator informed the FHWA's regional 
    offices, and through them the States, that ``the FHWA will not withhold 
    Federal-aid funds from States which issue nondivisible load permits to 
    emergency vehicles equipped for their intended use. We will not require 
    that the vehicles have a full crew or be operating under emergency 
    conditions. States may set whatever permit terms, conditions, and fees 
    they consider appropriate.'' The Federal Highway Administrator added 
    that this policy ``is compatible with the Agency's draft definition'' 
    published on February 25, 1993, in the SNPRM and that if it ``in any 
    way conflicts with the definition ultimately adopted through the 
    rulemaking process, appropriate action will be taken to amend or 
    rescind the policy.''
        The Federal Highway Administrator's decision was based upon 
    conclusions set forth in his November 9, 1993, letter:
    
        Some States may have refused to issue nondivisible load permits 
    to emergency vehicles because much of their equipment is readily 
    detachable. Fire trucks often carry firefighting teams, water, 
    hoses, axes, respirators and other devices; advanced life support 
    vehicles typically carry at least two paramedics (one of whom 
    drives), defibrillators, oxygen tanks, stretchers, and medical 
    supplies. In one sense, ancillary equipment and personnel are 
    ``divisible'' parts of the load, and removing them might lighten an 
    emergency vehicle enough to restore compliance with Interstate 
    weight limits. Doing so, however, would defeat the purpose of these 
    vehicles and make it impossible for them to respond effectively to 
    emergencies. New vehicles may even be overweight as they leave the 
    final stage manufacturing facility, either because the base vehicle 
    is particularly heavy or because ancillary equipment is supplied 
    with it. The equipment that could be removed from emergency vehicles 
    to reduce weight is essential to the services they are designed to 
    perform. These vehicles and loads are functionally if not physically 
    nondivisible, and I believe the States should have the option to 
    treat them as such.
    
        In the language of the regulation we are adopting today, requiring 
    an emergency vehicle to unload separable pieces of equipment would 
    ``compromise the intended use of the vehicle.'' Emergency vehicles meet 
    the definition of a nondivisible vehicle or load.
        Spent Nuclear Fuel: The Pennsylvania DOT pointed out that the FHWA 
    informed the American Association of State Highway and Transportation 
    Officials several years ago that the FHWA regards overweight casks used 
    to move spent nuclear fuel as nondivisible. This determination was not 
    reflected in the SNPRM. The casks used to transport spent nuclear 
    materials, especially nuclear fuel, are extraordinarily strong and 
    heavy, both to prevent a release in case the transporter vehicle was 
    involved in an accident and to block radiation that would penetrate 
    lighter materials. Some of these containment devices can make a vehicle 
    overweight even before the nuclear materials are loaded. These vehicles 
    cannot be used for any other cargo or reduced to legal weights without 
    frustrating their purpose. A new provision has therefore been added 
    which essentially states that specially designed casks used to move 
    spent nuclear fuel meet the definition of a nondivisible load.
        Other Issues: The Pennsylvania DOT suggested that the SNPRM be 
    amended to acknowledge that both the President and State governors
    
        [H]ave the executive authority to temporarily modify any vehicle 
    size or weight law or regulation, including the nondivisible 
    criteria, in order to provide for emergency relief to promote the 
    general welfare and public safety, without threat of Federal 
    sanction after the emergency.
    
    While the FHWA would not necessarily impose sanctions if weight 
    enforcement suffered during emergencies that threatened public welfare, 
    Federal weight law simply does not authorize waivers of the Interstate 
    limits or regulatory definitions.
        The Connecticut DOT suggested that we use the definition of a 
    nondivisible load to establish ``an Ultimate Limit or a guideline to be 
    used by manufacturing.'' Federal size and weight laws confer no 
    authority to regulate manufacturers.
        The FHWA mentioned in the SNPRM that bulk commodities such as 
    liquids, grain, and cement are inherently divisible. The CRASH 
    suggested that the definition include ``a much more complete listing of 
    loads that are inherently divisible * * * .'' In view of the enormous 
    variety of products that move by truck, we do not believe divisible 
    loads could reasonably be itemized.
        Grove Worldwide, a manufacturer of cranes, proposed that a load be 
    defined as nondivisible if dismantling it would cause a competitive 
    disadvantage, compromise the integrity and safety of the equipment when 
    disassembled, or jeopardize the warranty. The FHWA considers these 
    tests too far removed from the question of physical divisibility to be 
    appropriate.
    
    Procedure to Review and Correct Final List
    
        Sections 1023 and 4006 of the ISTEA provide a review and correction 
    procedure for the final list of ISTEA vehicles, published today as 
    appendix C to 23 CFR part 658. Any person or State may request that the 
    Secretary review the final list to determine if there is cause to 
    believe that it contains a mistake. The Secretary may also initiate the 
    review. If the Secretary believes an error exists, he or she must 
    commence a proceeding to determine if the list should be corrected, and 
    if so, make the correction. Proposed language establishing such a 
    procedure was included in the SNPRM. No comments were received on this 
    issue. Accordingly, that language has been adopted, unchanged, by this 
    final rule in Sec. 658.23(f).
    
    Temporary Exemption for Public Transit Vehicles
    
        Section 1023 of the ISTEA was amended by the Department of 
    Transportation and Related Agencies Appropriations Act for fiscal year 
    (FY) 1993, Public Law 102-388, 106 Stat. 1520. Section 341 added a new 
    subsection (h) which reads in part as follows:
    
        (h) Public Transit Vehicles.--
        (1) Temporary Exemption.--The second sentence of section 127 of 
    title 23, United States Code, relating to axle weight limitations 
    for vehicles using the Dwight D. Eisenhower System of Interstate and 
    Defense Highways, shall not apply, in the 2-year period beginning on 
    the date of the enactment of this Act, to any vehicle which is 
    regularly and exclusively used as an intrastate public agency 
    transit passenger bus. The Secretary may extend such 2-year period 
    for an additional year.
    
        This prevents the FHWA from sanctioning States that fail to enforce 
    the Interstate axle-weight limits for public transit vehicles at least 
    until October 6, 1994. If the Secretary exercises the authority to 
    extend the exemption an additional year, it would apply until October 
    6, 1995. The 2-year exemption was included in the ISTEA to allow States 
    to suspend axle weight enforcement on the Interstate System against 
    public transit vehicles while the Secretary conducts the study called 
    for in section 1023(h)(2). That study, which is currently underway, is 
    to determine whether or not public transit vehicles should be exempted 
    from the requirements of 23 U.S.C. 127, State weight laws, or if such 
    laws should be modified to accommodate these vehicles. The FHWA and the 
    Federal Transit Administration published a joint notice and request for 
    comments on this issue on November 16, 1993 (58 FR 60481). A report on 
    the results of the study, along with recommendations, will ultimately 
    be submitted by the Secretary to Congress.
        In a comment to the SNPRM docket, the American Public Transit 
    Association urged that the temporary exemption language be codified 
    into part 658. The FHWA agrees with this comment. Accordingly, the 
    exemption is codified in this final rule at Sec. 658.17(k).
    
    Temporary Exemption for Emergency Vehicles
    
        Section 1023(e) of the ISTEA added the following exemption from 23 
    U.S.C. 127:
    
        (1) Temporary Exemption.--The second sentence of section 127 of 
    title 23, United States Code, relating to axle weight limitations 
    and the bridge formula for vehicles using the Dwight D. Eisenhower 
    System of Interstate and Defense Highways, shall not apply, in the 
    2-year period beginning on the date of the enactment of this Act, to 
    any existing vehicle which is used for the purpose of protecting 
    persons and property from fires and other disasters that threaten 
    public safety and which is in actual operation before such date of 
    enactment and to any new vehicle to be used for such purpose while 
    such vehicle is being delivered to a fire fighting agency. The 
    Secretary may extend such 2-year period for an additional year.
    
        This prevented the FHWA from sanctioning States that failed to 
    enforce the Interstate axle-weight and Bridge Formula limits for fire 
    or emergency vehicles in actual operation on or before December 18, 
    1991, and for such equipment being delivered from the manufacturer to a 
    fire department. The normal gross weight limit was not affected by the 
    exemption. The exemption remained in effect through December 18, 1993. 
    The SNPRM proposed to codify the exemption at Sec. 658.17(k).
        Two comments were received on this issue. The South Dakota DOT 
    expressed its desire to go on record as ``not in favor of allowing a 
    temporary or permanent axle weight exemption or bridge formula weight 
    exemption for emergency vehicles.'' The State contends that ``operation 
    of these vehicles overweight threatens the public's safety'' and ``that 
    emergency vehicles should be designed to operate within legal size and 
    weight limits.'' The Caltrans objected to the FHWA's interpretation of 
    the law which indicated that the normal gross weight limit (80,000 
    pounds) remained in effect during the period of the exemption. They 
    contend that gross weight is determined by the Bridge Formula and that 
    our interpretation was contradictory.
        The FHWA believes that Congress intended the exemption in section 
    1023(e)(1) to cover (1) single- and tandem-axle limits, (2) application 
    of the bridge formula to intermediate axles (the inner bridge limits), 
    and (3) application of the Bridge Formula to the overall wheelbase of 
    the vehicle (the outer bridge limit). However, the 80,000-pound maximum 
    gross weight allowed by 23 U.S.C. 127(a) is not inherently part of the 
    Bridge Formula. It is a separate statutory restriction, and we do not 
    believe Congress intended to authorize an exemption to the 80,000-pound 
    limit.
        The 2-year exemption was included in the ISTEA to allow States to 
    suspend enforcement action against these vehicles while the Secretary 
    conducted the study called for in section 1023(e)(2). That study has 
    been completed, as indicated above, and the authority of the Secretary 
    to extend the temporary exemption an additional year will not be 
    exercised. The temporary exemption expired December 18, 1993. However, 
    the definition of a nondivisible load adopted in this final rule 
    specifically declares emergency vehicles to be nondivisible. States may 
    therefore issue overweight permits for these vehicles if they wish.
    
    Interstate System Weight Requirements
    
        The first sentence in 23 U.S.C. 127(a) was amended by the STAA of 
    1982 to require all States to allow the maximum weights permitted by 
    Federal law on the Interstate System. In effect, the weight limits set 
    forth in section 127 became minimums which the States must allow, as 
    well as the maximums the States could allow, on the Interstate System. 
    Since the STAA amendment of section 127 became effective (January 6, 
    1983), States have occasionally argued that the amendment applied only 
    to the single-axle, tandem-axle, and maximum gross weight limits, and 
    not to gross weights developed by the Bridge Formula. In addition, a 
    degree of confusion regarding applicability has lingered over the years 
    as a result of the regulations issued to implement the STAA (49 FR 
    23302, June 5, 1984). Although those regulations were published 1\1/2\ 
    years after enactment of the STAA, the statutory action making the 
    weight value minimums was not highlighted nor was any regulatory 
    language included.
        The SNPRM proposed to clarify and resolve this issue by including a 
    Sec. 658.17(f) as follows.
    
        (f) States may not enforce on the Interstate System vehicle 
    weight limits of less than 20,000 pounds on a single axle, 34,000 
    pounds on a tandem axle, or the weights derived from the bridge 
    formula, up to a maximum of 80,000 pounds, including all enforcement 
    tolerances.
    
        Comments on this proposal were received from six State Departments 
    of Transportation (Arizona, Montana, Nevada, Oregon, South Dakota, and 
    Washington), as well as from the WASHTO's Subcommittee on Highway 
    Transport. All seven commenters objected to the paragraph as proposed 
    for fear that it would no longer allow the States to further control 
    axle weight using a regulation based on pounds per inch of tire width. 
    Each of the six States providing direct comments currently has this 
    type of weight control regulation in force. The ``Guide For Uniform 
    Laws and Regulations Governing Truck Size and Weight Among the WASHTO 
    States,'' prepared by the WASHTO Subcommittee on Highway Transport and 
    adopted by the WASHTO Policy Committee on June 26, 1993, recommends 
    that all 17 member States adopt a 600-pound/inch tire width weight 
    control.
        State tire loading regulations are intended to limit the use of 
    single tires or wheels designed for dual tire applications. This is a 
    practice which results in higher pavement stress and shorter pavement 
    life, and greatly reduces the safety margin provided by dual tires. 
    Depending on the pound-per-inch limit chosen, these regulations may 
    also restrict the use of some ``super single'' tires. The Washington 
    State DOT included in its docket comments a copy of a report of 
    research on the effects of wide based single tires on flexible 
    pavements conducted by the FHWA at our Pavement Testing Facility during 
    1989 and 1990. Dual 11R22.5 radial tires, previously identified as one 
    of the most common truck tires in use today, were tested against a 425/
    65R22.5 wide base single tire. Under a load rating methodology 
    established by the United States Tire and Rim Association, the load 
    ratings for the duals and the single are equivalent; however, the 
    footprint on the pavement is significantly different. The approximate 
    footprint of an 11R22.5 tire is 8.5 inches. Thus, two sets of duals 
    (four tires) can result in approximately 34 inches of tire being 
    available to transmit an axle load to the pavement. For the 425/65R22.5 
    wide base tire, the footprint is approximately 11 inches, which would 
    make approximately 22 inches available to transmit an axle load to the 
    pavement. The research demonstrated that the 425/65R22.5 wide based 
    single tire was significantly more damaging to conventional flexible 
    pavements than the traditional 11R22.5 dual tires.
         The Federal axle weight limits on the Interstate System were 
    adopted to protect the tremendous Federal investment in that System. 
    Restrictions on the weight a tire may carry, based on its width, are 
    consistent with that goal and not forbidden by Federal law. It would be 
    anomalous to adopt axle weight limits to protect Interstate System 
    pavements and then prevent States from blocking the use of tires so 
    narrow that much of the protection was lost. In addition, a pound-per-
    inch tire limit does not directly limit the weight that an axle may 
    carry, since additional or wider tires may be utilized. Therefore, 
    unless such restrictions operate so that, as a practical matter, axles 
    cannot be loaded to the Federal weight limits, they are not 
    inconsistent with 23 U.S.C. 127. We believe that laws limiting tire 
    weights as low as 500 pounds per inch width of tire or tread width will 
    allow axles to be loaded to the Federal axle weight limits without 
    particular difficulty.
        Steering axles must be treated differently, however, since they 
    cannot always be equipped with wider or additional tires. The FHWA has 
    already recognized a different standard for steering axles by not 
    requiring States to allow truckers to load them to 20,000 pounds when 
    the manufacturer's weight rating is less than that. Therefore, States 
    may not impose pound-per-inch restrictions that would reduce the 
    allowed weight of steering axles on the Interstate System to less than 
    20,000 pounds or the manufacturer's weight rating, whichever is lower.
        Arizona, Montana, and Oregon also suggested that proposed 
    Sec. 658.17(f) be amended to allow temporary weight restrictions based 
    on climatic conditions or emergencies.
        Some northern States have for decades enforced lower axle limits 
    during spring thaw. When moisture in a pavement's sub-base, frozen 
    during the winter months, begins to melt, the load-carrying capacity of 
    the pavement structure is reduced until the moisture drains. The degree 
    of reduction is a function of the overall pavement structure thickness, 
    the type of underlying material, amount of moisture, and depth of frost 
    penetration.
        Federal weight restrictions apply only to the Interstate System. 
    The standards to which the System has been built include pavement 
    designs developed with the strength to allow maximum legal weights year 
    round. The FHWA does not agree that there is a need to provide 
    regulatory flexibility for climatic conditions. The pavement design 
    parameters of the Interstate System preclude the need for this 
    authority. However, the States do retain the authority to establish 
    such restrictions for highways that are not part of the Interstate 
    System.
        ``Emergency'' weight restrictions requested by States generally are 
    not restrictions at all, but rather the lessening of restrictions to 
    allow heavier weights. For example, when natural disasters occur, 
    carriers, relief agencies, or States would often like to allow trucks 
    carrying relief supplies to exceed normal weight limits. Federal law 
    simply does not allow waivers of this kind. On the other hand, if a 
    flood or earthquake has seriously weakened a bridge or stretch of 
    pavement, it remains within the police powers of the State or 
    municipality to close or limit access to the facility in order to 
    protect the public.
        Of the three exceptions to Sec. 658.17(f) sought by commenters, the 
    FHWA agrees that States should retain the authority to enforce the tire 
    loading restrictions, but does not concur in the request to provide 
    climatic or emergency restrictions. Accordingly, Sec. 658.17(f), as 
    proposed in the SNPRM, is amended to read as follows:
    
    
    Sec. 658.17  Weight.
    
    * * * * *
        (f) Except as provided herein, States may not enforce on the 
    Interstate System vehicle weight limits of less than 20,000 pounds 
    on a single axle, 34,000 pounds on a tandem axle, or the weights 
    derived from the Bridge Formula, up to a maximum of 80,000 pounds, 
    including all enforcement tolerances. States may not limit tire 
    loads to less than 500 pounds per inch of tire or tread width, 
    except that such limits may not be applied to tires on the steering 
    axle. States may not limit steering axle weights to less than 20,000 
    pounds or the axle rating established by the manufacturer, whichever 
    is lower.
    
    Bus Length and Access
    
        Section 4006(b)(1) of the ISTEA amended section 411(a) of the STAA 
    [49 U.S.C. app. 2311(a)] by inserting ``of less than 45 feet on the 
    length of any bus,'' after ``vehicle length limitation.''
        Section 4006(b)(2) of the ISTEA amended section 412(a)(2) of the 
    STAA [49 U.S.C. app. 2312(a)(2)] by inserting ``motor carrier of 
    passengers'' after ``household goods carriers.''
        The first provision has the effect of requiring States to allow 
    buses with a length of 45 feet or less on the NN and reasonable access 
    routes. The second provision requires States to allow motor carriers of 
    passengers to have the same access off the NN as household goods 
    carriers, i.e., to ``points of loading and unloading.'' In the SNPRM, 
    the FHWA proposed changes to the ``Length'' and ``Reasonable Access'' 
    sections of part 658 to account for these provisions.
        Comments on this proposal were received from the Caltrans and the 
    Department of California Highway Patrol. Both agencies recommended that 
    a final rule include definitions of both ``bus'' and ``motor carrier of 
    passengers'' to ``prevent confusion on the interpretation and 
    application of the regulations.'' The FHWA agrees with this comment.
        The STAA defines a ``commercial motor vehicle'' in part as ``any 
    self-propelled * * * vehicle used on the highways in [interstate] 
    commerce principally to transport passengers * * * (B) if such vehicle 
    is designed to transport more than 10 passengers, including the driver 
    * * *'' (49 U.S.C. app. 2301(1)(B)). While this definition applies only 
    to subchapter I of chapter 32 of title 49, U.S.C., which makes grants 
    available to States that agree to enforce Federal, or compatible State, 
    safety regulations, it is an indication of congressional intent. For 
    purposes of administering the commercial vehicle safety program, 
    ``bus'' was defined in 49 CFR 390.5 as ``any motor vehicle designed, 
    constructed, and or used for the transportation of passengers, 
    including taxicabs.'' The Motor Carrier Safety Act of 1984 amended the 
    definition of a bus to a ``vehicle designed to transport more than 15 
    passengers, including the driver * * *.'' (49 U.S.C. app. 2503(1)(B)).
        The intent of Congress, as expressed in the ISTEA, is to guarantee 
    national route availability and reasonable access for ``buses'' not 
    exceeding 45 feet in length. Since virtually all States already allowed 
    40-foot buses to operate Statewide prior to the ISTEA, the number of 
    passengers the vehicle is designed to carry is not an issue, simply the 
    establishment of a national standard length. Accordingly, this final 
    rule will use the most generic of the definitions already established, 
    that found in 49 CFR 390.5.
        While the term ``motor carrier of passengers'' has not previously 
    been defined, this type of operation can generally be characterized as 
    belonging to at least one of three groups: (1) Common carriers that 
    offer service on regular (and sometimes on irregular) routes, (2) 
    contract carriers that provide charter service to groups, or (3) 
    private carriers that do not serve the public but use buses as part of 
    some other enterprise. Someone who uses a 45-foot bus for recreational 
    or other non-business purposes would not qualify as a motor carrier of 
    passengers. For this final rule ``motor carrier of passengers'' is 
    defined as follows:
    
        Motor Carrier of Passengers--is a common, contract, or private 
    carrier using a bus to provide commercial transportation of 
    passengers.
    
        The list of definitions contained in 23 CFR 658.5 has been amended 
    to include this definition. In addition, the provisions of Sec. 658.13 
    (Length) and Sec. 658.19 (Reasonable Access) have been amended to 
    account for these provisions.
    
    Lengths of Trailers and Semitrailers
    
        Fruehauf Trailer Corporation (Fruehauf) commented that the FHWA 
    should clarify the methods by which length is determined for trailers 
    which are part of a multi-unit vehicle subject to the freeze. Because 
    of the attention focused on the LCV length issue by the freeze, 
    Fruehauf contends that it is important that all States (and enforcement 
    agencies) have a uniform understanding of how the length of the 
    individual units is to be determined. Fruehauf's specific concern is 
    with full trailers used in LCV's which are actually made up of a 
    semitrailer and a converter dolly.
        In a Notice of Interpretation (NOI) published on March 13, 1987, at 
    52 FR 7834, the FHWA addressed the issue of trailer or semitrailer 
    length, as part of an overall discussion of length and width exclusive 
    devices. The first length interpretation is relevant here.
    
        1. The length of a semitrailer equipped with an upper coupler 
    (mates with a truck tractor fifth wheel) and a full trailer (with 
    either a permanently mounted dolly or equipped with a converter 
    dolly) is to be measured from the front vertical plane of the 
    foremost transverse load carrying structure to the rear vertical 
    plane of the rearmost transverse load carrying structure. The towbar 
    of a full trailer is excluded from the length measurement (of that 
    trailer) since, technically, it carries no load, but rather it is 
    the means by which the trailer unit is drawn.
    
        The length of any two or more units subject to the freeze 
    requirements of section 4006 is to be measured from the front of the 
    foremost transverse load-carrying structure of the first cargo-carrying 
    unit to the rear of the rearmost transverse load-carrying structure of 
    the last such unit. The upper coupler on a semitrailer is not to be 
    included in the length determination of these units.
    
    National Network--California
    
        This final rule will also amend appendix A to 23 CFR part 658, 
    National Network--Federally-Designated Routes, to reflect the inclusion 
    of the I-580 Richmond-San Rafael Bridge (toll) in the NN. Under the 
    STAA, all Interstate System routes are part of the NN unless deletion 
    is authorized by law. The I-580 Richmond-San Rafael Bridge was withheld 
    from the NN until a direct connection to I-80 from the east end of the 
    bridge could be completed. This condition was reflected in Note 1 to 
    the California listing of NN routes in appendix A. Now that this 
    connection has been completed, the FHWA is amending appendix A by 
    removing Note 1 and redesignating Note 2 as ``Note.''
        This amendment will merely reflect the fact that the I-580 
    Richmond-San Rafael Bridge is now included in the NN pursuant to the 
    provisions of the STAA. For this reason, and the others set forth 
    above, the FHWA has determined that prior notice and opportunity for 
    public comment on this action are unnecessary. Furthermore, due to the 
    technical nature of this amendment, the FHWA has determined that prior 
    notice and opportunity for comment are not required under the U.S. 
    Department of Transportation's Regulatory Policies and Procedures, as 
    it is not anticipated that such action will result in receipt of useful 
    information.
    
    National Network--Virginia
    
        The ISTEA freeze applies to the operation of specified CMV's on the 
    Interstate and other portions of the NN. The identification of NN 
    routes in Virginia contained in appendix A to 23 CFR part 658 utilizes 
    Interstate System exit numbers to identify the beginning or end of some 
    NN routes. During 1992, the State converted all Interstate System exit 
    numbers from a consecutive number system to a milepost numbering 
    system. In response to this portion of the SNPRM, the State indicated 
    that there appeared to be a discrepancy between what was published in 
    the SNPRM and what the State was considering to be its NN.
        The State list not only includes those highway sections designated 
    by the Secretary which comprise appendix A to part 658, but also 
    additional segments which the State has also decided to open to STAA 
    vehicles. Each State retains the authority to open additional mileage, 
    beyond what is listed in appendix A of part 658, to STAA vehicles 
    without the approval of the Secretary. In order to identify NN routes 
    in Virginia which have been federally designated, we are reissuing the 
    State's NN routes in appendix A, 23 CFR part 658, to reflect the new 
    milepost-based exit numbers.
    
    Definition Of Maxi-Cube
    
        Among the vehicles specifically excluded from listing in appendix 
    C, and therefore not subject to the restrictions described in section 
    4006 of the ISTEA, is the maxi-cube vehicle. ``Maxi-Cube'' is a 
    registered trademark of LHT Industries, which designed the vehicle, but 
    the maxi-cube regulations adopted in this rule apply to any vehicles 
    that meet their terms.
        In 1987, Congress amended the STAA by adopting a definition of a 
    maxi-cube and authorizing the vehicle to operate on the same terms as 
    other STAA vehicles (49 U.S.C. app. 2311(f)(2) and 2311(c), 
    respectively). It soon became apparent that the definition, reproduced 
    below, was flawed:
    
        (2) For purposes of this section, maxi-cube vehicle means a 
    truck tractor combined with a semi-trailer and a separable cargo-
    carrying unit which is designed to be loaded and unloaded through 
    the semi-trailer, except that the entire combination shall not 
    exceed 65 feet in length and the separable cargo-carrying unit shall 
    not exceed 34 feet in length.
    
    49 U.S.C. app. 2311(f)(2).
    
        Although the term maxi-cube was intended to apply to a specific 
    combination of straight truck and trailing unit, the 1987 language 
    described the power unit as a ``truck tractor,'' which the STAA 
    elsewhere defines as ``the noncargo carrying power unit that operates 
    in combination with a semitrailer or trailer * * * `` (49 U.S.C. app. 
    2311(f)(1)).
        Theoretically, therefore, the maxi-cube is a noncargo-carrying 
    power unit combined with a semitrailer and a separable cargo-carrying 
    unit which is designed to be loaded and unloaded through the semi-
    trailer. Unfortunately, this vehicle is a chimera. The separable cargo-
    carrying unit cannot be placed on the ``noncargo carrying'' power unit, 
    and if it were placed on the semitrailer, the result would seem to be a 
    truck tractor-chassis-intermodal container combination. Container 
    vehicles had long been legal, however, so the 1987 language certainly 
    was not directed at them. In some sense all containers and semitrailers 
    are designed to be loaded and unloaded ``through'' themselves, but the 
    description does not really fit a combination with only one cargo-
    carrying unit. The fact is that the definition of the vehicle to be 
    authorized did not correspond to the actual vehicle.
        Recognizing the problem, Congress amended the STAA again in 1990 to 
    make maxi-cubes ``specialized equipment'' and thus eligible for the 
    special regulatory treatment authorized by 49 U.S.C. app. 2311(d). The 
    accompanying report of the House Appropriations Committee said the 
    following:
    
        The bill includes language (Sec. 327) amending section 411(d) of 
    the Surface Transportation Assistance Act of 1982 regarding maxi-
    cube vehicles. A maxi-cube vehicle is a truck combination consisting 
    of a power unit capable of carrying cargo that pulls a semitrailer. 
    The power unit is a single or tandem axle truck that carries either 
    a detachable or a permanently attached cargo box or platform. The 
    trailing unit is a semitrailer attached to the front unit by a 
    specially built draw bar which gives the entire combination a single 
    point of articulation. The front of the rear unit is specially 
    designed so cargo may be loaded through the rear unit to the front 
    unit. The length of the trailing cargo unit can be no more than 34 
    feet excluding the draw bar. The distance from the front of the 
    cargo box on the power unit to the rear of the trailing unit can be 
    no more than 60 feet.
    
    (H.R. Rep. No. 584, 101st Cong. 2d Sess. at 78-79 (1990).)
    
        Although this is an accurate description of a maxi-cube, the flawed 
    definition of the same vehicle in 49 U.S.C. app. 2311(f)(2) was not 
    repealed. In the SNPRM, the FHWA therefore exercised its broad 
    discretionary authority over specialized equipment to propose a 
    definition of the maxi-cube that largely codified the policy guidance 
    of the Committee Report while omitting or modifying the erroneous parts 
    of the statutory definition. We believe this is consistent with the 
    principle that ambiguous or confusing statutes must be interpreted and 
    implemented in a manner that minimizes difficulties and produces the 
    most sensible result.
        The definition of a maxi-cube proposed in the SNPRM has been 
    adopted in this final rule, with slight modifications for clarity. It 
    should be noted that the word ``semitrailer'' used in the statute and 
    Committee Report has been changed to ``trailer or semitrailer,'' since 
    some of the vehicles built as maxi-cubes in recent years are equipped 
    with pintle-hooks, non-load-bearing hitches used for full trailers. 
    Others are equipped with load-bearing fifth-wheel hitches typical of 
    semitrailers. This modification of the definition is well within the 
    FHWA's authority to promulgate rules to accommodate specialized 
    equipment.
        The SNPRM also proposed that maxi-cube vehicles should be measured 
    with the adjustable-length drawbar (if so equipped) at its maximum 
    extension, since we assumed that was how the drawbar would be 
    positioned for over-the-road operations. The Pennsylvania DOT supported 
    this proposal in its comments to the docket.
        It appears, however, that adjustable drawbars usually are not fully 
    extended when the vehicle is in motion. Magna Van and Coca Cola 
    commented that 24 inches is the normal distance between the first and 
    second units of their maxi-cube vehicles during over-the-road 
    operations, but that longer distances are used for access to driveways 
    and transferring freight in off-road situations. Other information 
    submitted to the docket indicated that 27 inches is probably the 
    longest distance between cargo units for highway travel. However, there 
    are times when a longer drawbar setting may be desirable, such as on 
    rough terrain to keep the cargo boxes from hitting each other; in urban 
    areas while making sharp turns; or while loading and unloading cargo 
    from the front unit while the rear unit is attached. The maximum 
    reported unit separation in these instances is 42 inches.
        The FHWA believes Congress intended the maxi-cube length limits to 
    apply to vehicles in their normal operational configuration. We have 
    concluded that the cargo capacity of these vehicles would be needlessly 
    reduced if the rule required length measurements to be made with the 
    drawbar at maximum extension, since that position is used only to 
    assist in low-speed maneuvering or loading and unloading. The last 
    sentence of Sec. 658.13(e)(4) has therefore been modified to read:
    
        If the maxi-cube vehicle is equipped with an adjustable drawbar, 
    the 60- and 65-foot distances shall be measured with a drawbar 
    spacing of not more than 27 inches. The drawbar may be temporarily 
    extended beyond that distance to maneuver or load the vehicle.
    
        The American Movers Conference believes that the load-through 
    feature of the maxi-cube should be made optional. We do not agree. That 
    language is included both in the statutory definition in 49 U.S.C. app. 
    2311(f)(2) and in the Appropriations Committee report. This feature is 
    one of the primary reasons Congress declared maxi-cubes specialized 
    equipment. Removing the load-through element from the definition would 
    make these vehicles indistinguishable from truck-trailer combinations.
        The State of Connecticut asked if the maxi-cube vehicle will be 
    designated as specialized equipment since it will be limited to the NN 
    and reasonable access routes. Maxi-cube vehicles are by statute 
    specialized equipment, and Federal regulations for such equipment apply 
    only on the NN and reasonable access routes.
        This action concludes the FHWA rulemaking proceeding that was 
    designated with the regulation identification number 2125-AC65.
    
    Beverage Semitrailers
    
        A rulemaking to designate as specialized equipment the 28-foot van-
    type, drop-frame beverage semitrailer when it is equipped with an upper 
    coupler plate that extends in front of the semitrailer, has been 
    underway since 1990. The last action on the subject was publication of 
    an NPRM on June 25, 1990, at 55 FR 25850. The final rule was being 
    prepared when the ISTEA was enacted. Since the rulemaking necessary to 
    implement the ``LCV-freeze'' would, like the beverage semitrailer rule, 
    amend 23 CFR part 658, the decision was made to include both in a 
    single document. Since they amend the same existing regulation, 
    combining them minimizes the number of separate changes made to an 
    already complex regulatory document.
        The STAA, codified at 49 U.S.C. app. 2311 et seq., established 
    length and width standards for vehicles using the highways designated 
    as the NN (appendix A to 23 CFR part 658 (1993)). The STAA prohibited 
    any State from enforcing a length limit of less than 28 feet on a 
    semitrailer or trailer operating in a truck tractor-semitrailer-trailer 
    combination on the NN (49 U.S.C. app. 2311 (a)). The STAA, under an 
    equipment grandfather provision, also allows the use of 28.5-foot 
    semitrailers and trailers in truck tractor-semitrailer-trailer 
    combinations if they were actually and lawfully operating on December 
    1, 1982, within a 65-foot overall length limit in any State. The 
    statute prohibited any State from denying reasonable access to points 
    of loading and unloading for a truck tractor pulling a single 28-foot 
    (28.5-foot if grandfathered) semitrailer that generally operates as 
    part of a truck tractor-semitrailer-trailer combination. In addition, 
    the STAA gave the Secretary authority to exclude from measurement of 
    trailer length and width, devices necessary for the safe and efficient 
    operation of CMV's, provided length exclusive devices did not have, by 
    design or use, the capability to carry cargo (49 U.S.C. app. 2311(h), 
    2316(b)).
        Questions involving permissible vehicle length and length exclusive 
    devices are critical to a new design for 28-foot beverage semitrailers. 
    As used in this proceeding, ``beverage'' means a liquid for drinking, 
    including water. One new design places the kingpin under the nose of 
    the trailer with a portion of the upper coupler plate extending beyond 
    the front of the vehicle. Since these beverage semitrailers use an 
    enclosed van-type, drop-frame design, mounting the kingpin in this 
    manner allows the drop-frame portion of the semitrailer to be extended 
    forward. The FHWA has issued several NOI of length and width exclusive 
    devices. The most recent was published on March 13, 1987, at 52 FR 
    7834. That NOI recognized a number of length-exclusive design features, 
    including (1) the pickup plate lip of the upper coupler, and (2) any 
    non-load-carrying device which falls within the swing radius of the 
    semitrailer (measured from the center line of the kingpin to the front 
    corner of the semitrailer). As applied to the new design described 
    above, these two provisions have proved difficult to administer and 
    have caused confusion and misunderstanding between the FHWA and the 
    industry. The June 25, 1990, NPRM proposed to designate as specialized 
    equipment van-type, drop-frame beverage semitrailers. A 30-day comment 
    period (through July 25, 1990) was provided.
        In addition to seeking general comments, the NPRM requested all 
    interested parties to respond to four questions concerning these 
    vehicles.
        The FHWA solicited comments on the following questions as well as 
    other comments:
        1. Should ``beverage trailer'' and ``beverage semitrailer'' be 
    defined in the proposed regulation?
        2. Is the proposed length limit for the upper coupler extension of 
    the semitrailer clear?
        3. Will the semitrailer, as configured, be as safe as one with the 
    upper coupler plate positioned fully under the semitrailer?
        4. Will the position of the center of the kingpin, not more than 28 
    feet from the rear of the semitrailer, produce offtracking 
    characteristics that are significantly greater than those of 
    conventional 28-foot semitrailers?
    
    Discussion
    
        Eight responses to the June 25, 1990, NPRM were submitted to the 
    docket. The respondents included four State Departments of 
    Transportation; California (Caltrans), Florida (FDOT), Minnesota 
    (MnDOT), and Virginia (VDOT) and the Connecticut Department of Motor 
    Vehicles, the Port Authority of New York and New Jersey, Hackney and 
    Sons, Inc. (trailer manufacturer), and one individual. Of these 
    respondents, six favored designating the beverage semitrailer as 
    specified equipment, one (Caltrans) opposed, and one (VDOT) was not 
    sure the vehicle could operate on its current system of highways for 
    STAA dimensioned vehicles.
    
    Comments Submitted to Docket 90-9
    
        1. Should ``beverage trailer'' and ``beverage semitrailer'' be 
    defined in the proposed regulation?
        Six respondents commented on defining the ``beverage trailer'' and 
    ``beverage semitrailer.'' Two State DOT's (FDOT and VDOT) and the Port 
    Authority requested that the terms ``beverage trailer'' and ``beverage 
    semitrailer'' be defined in order to administer the regulation without 
    erroneous interpretations. They see this terminology as a potential 
    enforcement problem. The individual stated that the definition was 
    incomplete as it was now written and should specify that the trailer 
    has side access only for cargo. The trailer manufacturer requested that 
    it not be defined because the trailers are also used for palletized 
    cargo as well. Other types of cargo hauled on this type of trailer 
    include automobile batteries, coin compartments from pay telephones, 
    mushrooms, and nursery plants.
        The trailer manufacturer also suggested that the regulation read as 
    follows: ``with the center line of the kingpin mounted not more than 28 
    feet from the rear of the semitrailer * * *.'' It requested the 
    addition of the words ``the center line of'' because (1) in the 
    semitrailer design under consideration, every inch is important, (2) 
    this change would provide more swing clearance for the tractor under 
    the gooseneck area of the semitrailer, (3) the length of the trailer 
    body would not be increased, and (4) it is common in the industry to 
    specify kingpin location by kingpin center. Based on these comments, 
    the FHWA has modified the definition to state that the semitrailer have 
    ``side access only'' and that the cargo be limited to bottled or canned 
    beverages. The definition has also been revised to allow the 28-foot 
    length to be measured from the centerline of the kingpin to the rear of 
    the semitrailer.
        2. Is the proposed length limit for the upper coupler extension of 
    the semitrailer clear?
        The trailer manufacturer and the individual commented that the 
    proposed length limit of the upper coupler was clear and in a workable 
    location. They did not foresee any possible misinterpretation. The 
    trailer manufacturer responded that by limiting the upper coupler 
    extension to fall within the swing radius of the front corner of the 
    semitrailer it is both clear and very workable. This approach has been 
    allowed for the purpose of excluding other front-mounted items from 
    length measurement and accordingly is to be used for this case as well. 
    The FDOT commented that the proposed length limit was not clear as 
    described in the June 25, 1990, NPRM. The FDOT also suggests that 
    language is needed to assure that the coupler plate does not become a 
    cargo carrier in and of itself and that the device stays reasonable in 
    length. The MnDOT responded that its law currently allows semitrailers 
    of 28.5 feet, in three vehicle combinations, and the proposed design 
    would only minimally exceed the current standard.
        In accordance with these comments, the FHWA concludes that not 
    allowing the upper coupler plate extension to extend beyond the swing 
    radius of the semitrailer is a clear and sufficient means to restrict 
    the length of this device. The operational rules have been amended to 
    specify that the upper coupler plate itself cannot be used to carry 
    cargo.
        3. Will the semitrailer, as configured, be as safe as one with the 
    upper coupler plate positioned fully under the semitrailer?
        The Caltrans, MnDOT, trailer manufacturer, and individual agreed 
    that the configuration would be as safe as the upper coupler positioned 
    fully under the semitrailer. The FDOT commented that the final rule 
    should include requirements similar to those found in 49 CFR part 393, 
    subpart F--Coupling Devices and Towing Methods. These and other Federal 
    regulations continue to apply to beverage trailers and need not be 
    cross-referenced in every other applicable regulation. Due to the 
    specialized nature of the equipment discussed here, however, reference 
    to an applicable provision of 49 CFR part 393 is included.
        The trailer manufacturer responded that the configuration would be 
    safe because the maximum kingpin-to-trailer axle span will be 25.5 
    feet. A single 53-foot semitrailer can have a kingpin-to-center of 
    trailer tandem-axle span of 45.5 feet and still be considered safe. The 
    individual commented that there is no reason to believe that trailers 
    produced to this configuration would be less safe than trailers with 
    upper couplers fully under the trailer. Dump trailers and short 
    container chassis often have configurations that place the kingpin 
    forward of the body.
        The VDOT commented that demonstrations should be conducted with 
    each type of semitrailer to determine any difference between the two 
    mounting plates. A demonstration is not necessary because this style of 
    trailer has been in operation for several years, and the operating 
    characteristics are known to be compatible to other trailers in current 
    use.
        Based on the comments, the FHWA concludes that the semitrailer as 
    configured will be as safe as one with the upper coupler positioned 
    fully under the semitrailer.
        4. Will the position of the kingpin, not more than 28 feet from the 
    rear of the semitrailer, produce offtracking characteristics that are 
    significantly greater than those of conventional 28-foot semitrailers?
        The Port Authority and the manufacturer responded ``no'' to the 
    question. The Port Authority commented that it appears to them that the 
    offtracking of the beverage semitrailer combinations set forth in the 
    proposed regulation will not differ significantly from the conventional 
    semitrailer combinations already permitted upon port authority 
    vehicular crossings. The trailer manufacturer used a ``sum of squares'' 
    method to determine offtracking (Society of Automotive Engineers (SAE) 
    J695) and does not find a great increase in offtracking.
        The individual commented that offtracking of these specialized 
    trailers will be greater than conventional 28-foot trailers since the 
    distance from the kingpin to the trailer's axle will increase by up to 
    3 feet. Also, using the techniques of SAE J695, he calculated the 
    offtracking for conventional and beverage semitrailers as shown in the 
    following table: 
    
               Comparison of Offtracking of Selected Semitrailers           
    ------------------------------------------------------------------------
          Radius

    120 feet.........  2.55 feet........  3.17 feet.......  8.53 feet.      
    ------------------------------------------------------------------------
    
        The FDOT responded that the potential of an extra 2 or 3 feet to 
    the kingpin setting may be important with units running as a tandem 
    combination; however, as a single-unit semitrailer, the difference 
    would be insignificant when considering the 41-foot kingpin setting 
    that is being discussed as a de facto national limit for such settings.
        Based on the comments, the FHWA concludes that the offtracking 
    characteristics of the beverage semitrailer being designated as 
    specialized equipment are not significantly greater than those of 
    conventional 28-foot semitrailers.
    5. Other comments.
        The Caltrans, FDOT, and MnDOT expressed concerns about future 
    petitions for the FHWA to propose a similar rule for longer beverage 
    semitrailers or semitrailers of a similar design for carrying other 
    goods. The Caltrans' concern is that the beverage semitrailer is 
    another small step toward allowing larger vehicles by means of an 
    exception process. For example, since the weight of the beverage 
    semitrailer and load rest on the upper coupler plate extending from the 
    front of the semitrailer, why not allow the van portion to the 
    semitrailer to be extended over the plate? Also, if a weight supporting 
    upper coupler plate is permitted for a 28-foot beverage semitrailer, is 
    a 48-foot beverage semitrailer next? The possibility of a 48-foot 
    beverage semitrailer raises strong concerns about offtracking. A 
    typical semitrailer has the kingpin located 3 feet from the front of 
    the semitrailer. The Caltrans' evaluation of the State Highway System 
    for designation of terminal access routes is on the basis of a 48-foot 
    trailer with a 43-foot kingpin-to-center of the rearmost axle which is 
    equivalent to the 41-foot kingpin-to-center of tandem axles.
        The FDOT responded that the proposed rule needs to be modified to 
    assure that other trailers/semitrailers do not grow in length as a 
    result of this proposed rule. It should be expected that other segments 
    of the industry will seek the same benefits as are being provided to 
    the beverage haulers under this proposed rule. Similarly, the MnDOT 
    would discourage the FHWA from further ``piecemeal'' exemptions until a 
    comprehensive review of the commercial vehicle length definition is 
    conducted. The State finds that this examination is warranted in light 
    of the recent research from the Roads and Transportation Association of 
    Canada, which demonstrates that the U.S. may in fact be discouraging 
    uniformity and the use of more stable vehicle configurations on U.S. 
    highways, due to current vehicle definitions. The State supported the 
    use of the terms ``box length'' and uniform ``kingpin or wheelbase'' 
    for specifying length limits for commercial vehicle equipment. On the 
    other hand, the MnDOT also commented that the configuration under 
    discussion here would not have adverse effects on pavements, bridges, 
    or maneuvering.
        The FHWA understands the concerns of these States about its 
    handling of petitions from other segments of the trucking industry for 
    relief similar to that being provided for beverage semitrailers. The 
    FHWA also recognizes that different ways to specify trailer length 
    provisions do exist. Future petitions for similar relief provisions 
    will be evaluated with these concerns in mind.
        Finally, the Caltrans commented that the 28-foot beverage 
    semitrailer was not specialized equipment, but rather another attempt 
    to incrementally increase (by regulatory action) the limits set by the 
    STAA. The FHWA disagrees. This equipment as defined by this rulemaking 
    is highly specialized.
    
    Conclusions
    
        In order to remove any doubt about using 28-foot beverage 
    semitrailers with an upper coupler plate that extends beyond the front 
    of the semitrailer on the NN without a special permit, the FHWA is 
    designating them as specialized equipment pursuant to our authority 
    under section 411(d) of the STAA (49 U.S.C. app. 2311(d)).
        This designation as specialized equipment applies only to van-type, 
    drop-frame, side-loading only, beverage semitrailers for which the 
    upper coupler plate extends beyond the front of the semitrailer, and 
    the distance from the centerline of the kingpin connection to the rear 
    of the semitrailer is not greater than 28 feet. The rule preempts 
    States from imposing an overall length limit on such vehicles operating 
    in semitrailer or double trailer combinations and guarantees these 
    truck tractor-single beverage semitrailer combinations the same access 
    to points of loading and unloading as 28-foot (28.5-foot if 
    grandfathered) semitrailers in 23 CFR 658.19. After reviewing the 
    comments to the docket, the FHWA has concluded that this action would 
    allow for a productivity gain without adversely effecting public 
    safety. A definition of beverage semitrailer has been added to 
    Sec. 658.5, and regulatory language has been added to Sec. 658.13. This 
    action concludes the FHWA rulemaking proceeding that was designated 
    with the regulation identification number 2125-AC57.
    
    Certification
    
        Section 1023(c) of the ISTEA amended 23 U.S.C. 141(b) by adding a 
    new sentence at the end which reads as follows:
    
        Each State shall also certify that it is enforcing and complying 
    with the provisions of section 127(d) of this title and section 
    411(j) of the Surface Transportation Assistance Act of 1982.
    
    (49 U.S.C. app. 2311(j)).
    
        As implemented by 23 CFR 657.13, 23 U.S.C. 141(b) requires each 
    State to certify annually that it is enforcing its size and weight laws 
    on the Federal-aid Primary System (FAP), Federal-aid Urban System 
    (FAU), Federal-aid Secondary System (FAS), and the Interstate System in 
    accordance with 23 U.S.C. 127.
        Under the new ISTEA provision, States must also certify that they 
    are enforcing and complying with the ISTEA freeze on the use of LCV's 
    and other multi-unit vehicles. Failure to certify would subject a State 
    to the penalties provided in 23 U.S.C. 141(c)(2).
        The ISTEA, however, effectively replaced the FAP with the NHS, and 
    eliminated the FAU and FAS Systems, without providing a conforming 
    amendment to 23 U.S.C. 141(b). Until 23 U.S.C. 141 is amended to 
    reflect changes in system nomenclature, the FHWA will require the 
    States to certify size and weight enforcement on those routes which, 
    prior to October 1, 1991, were designated as part of the FAP, FAS, or 
    FAU Systems.
        The State of Alaska objected to the certification statement 
    proposed in the SNPRM. That statement would require the State to 
    certify that it is enforcing the freeze provisions of 23 U.S.C. 127(d) 
    and that its State laws are consistent with 23 U.S.C. 127 (a) and (b). 
    Alaska asserts that section 127 does not apply to the State because the 
    State does not have any Interstate System mileage as defined in 23 
    U.S.C. 103, 139(a) or 139(b). The FHWA agrees with this comment.
        The same situation with respect to highway system also exists in 
    Puerto Rico, which is considered a ``State'' for the purposes of title 
    23, United States Code.
        The certification language proposed by the SNPRM has been retained, 
    except that language to recognize the situations in Alaska and Puerto 
    Rico has also been included.
        Language describing size and weight enforcement coverage in urban 
    areas has also been clarified in this final rule.
        Since its initial publication in 1980 (45 FR 52365), Sec. 657.15 
    has required that ``Urban areas not subject to State jurisdiction shall 
    be identified and the statement shall address total (Federal-aid) 
    mileage involved and an analysis of enforcement efforts in such 
    areas.'' In practice, the FHWA's interpretation of this requirement 
    over the years has been to focus on those areas over 50,000 population, 
    also called urbanized areas (as determined by the Bureau of the 
    Census). The FHWA recognizes an area as ``urban'' when the population 
    is 5,000 or more. It is not now, nor has it ever been, the intent of 
    the FHWA to require extensive size and weight enforcement activities, 
    or an analysis thereof, in areas with a population between 5,000 and 
    50,000. The intent of this requirement has always been to ensure that 
    an adequate size and weight enforcement effort be conducted by larger 
    cities, i.e., over 50,000 population, where the State weight 
    enforcement agency does not have legal jurisdiction. Substitution of 
    the word ``urbanized'' for ``urban'' (both terms as defined in 23 
    U.S.C. 101) in the second sentence of Sec. 657.15(b) accomplishes this 
    clarification.
        What, prior to October 1, 1991, was Federal-aid system mileage in 
    urban areas of less than 50,000 population, should continue to be 
    covered by the State's overall weight enforcement program. This change 
    in wording does not preclude, nor should it discourage, weight 
    enforcement activity by local jurisdictions. Such activity is 
    encouraged with results to be reported as part of the overall 
    enforcement activity in the State.
    
    Conforming Amendment
    
        ISTEA section 4006(c) consisted of a conforming amendment as 
    follows:
    
        Section 411(e)(1) of such Act (the STAA of 1982) is amended by 
    striking ``those Primary System highways'' and inserting ``those 
    highways of the Federal-aid primary system in existence on June 1, 
    1991 * * *.''
    
        Section 411(e)(1) of the STAA describes the type of highways that 
    the Secretary shall designate as open to the vehicles described by the 
    STAA. These designated highways, in combination with the Interstate 
    System, have come to be known as the NN. The ISTEA effectively replaced 
    what had been known as the FAP System with the NHS. This conforming 
    amendment corrects the technical problem of designating segments of a 
    highway system (the FAP) which no longer exists. The necessary 
    corrections to the definitions of ``Federal-aid Primary System'' and 
    ``National Network,'' both found in 23 CFR 658.5, have been made by 
    this final rule.
    
    Operation of Certain Specialized Hauling Vehicles on Interstate Route 
    68
    
        Section 1023(d) of the ISTEA added 23 U.S.C. 127(e) to read as 
    follows:
    
        (e) Operation of Certain Specialized Hauling Vehicles on 
    Interstate Route 68.--The single-axle, tandem-axle, and bridge 
    formula limits set forth in subsection (a) (23 U.S.C. 127(a)) shall 
    not apply to the operation on Interstate Route 68 in Garrett and 
    Allegany Counties, Maryland, of any specialized vehicle equipped 
    with a steering axle and a tridem axle and used for hauling coal, 
    logs, and pulpwood if such vehicle is of a type of vehicle as was 
    operating in such counties on United States Route 40 or 48 for such 
    purpose on August 1, 1991.
    
        This exempts the described vehicles with selected cargo from the 
    axle and Bridge Formula weight limits that Maryland must enforce on 
    Interstate Route 68 in Allegany and Garrett Counties. However, the 
    normal gross weight limit (80,000 pounds) remains in effect. This 
    change is adopted by this final rule in Sec. 658.17(j).
    
    Reassignment of Size and Weight Responsibilities Within the FHWA
    
        On October 1, 1991, responsibility for the vehicle Size and Weight 
    and NN Programs in the FHWA's regional and divisional offices was 
    transferred to the Office of Motor Carriers. Revisions to 23 CFR 657.11 
    and 657.17 were proposed in the SNPRM to reflect this change.
        No comments were received on this issue. This final rule includes 
    the changes as proposed.
        Size and weight responsibilities in the Washington, DC., 
    Headquarters office remain assigned to the Office of Motor Carriers.
    
    Rulemaking Analyses and Notices
    
        This final rule implements sections 1023 and 4006 of the ISTEA, 
    which restrict the operation of LCV's on the Interstate Highway System 
    and CMV combinations with two or more cargo-carrying units on the NN to 
    the type of vehicles in use on or before June 1, 1991, subject to 
    whatever State rules, regulations, or restrictions were in effect on 
    that date.
        As noted in the following paragraphs, the FHWA has determined that 
    this rulemaking is: (1) Not a significant regulatory action within the 
    meaning of Executive Order 12866; (2) not a significant action within 
    the meaning of Department of Transportation Regulatory Policies and 
    Procedures; (3) will not have a significant economic impact on a 
    substantial number of small entities; (4) does not require the 
    preparation of a federalism assessment; and (5) does not require the 
    preparation of an environmental impact statement. All of these findings 
    were made and included in the NPRM and again in the SNPRM, in each case 
    after the FHWA had carefully reviewed the applicable Federal statutes 
    and Executive Orders.
        The WTA submitted comments to the docket in response to both the 
    NPRM and the SNPRM challenging what it saw as the FHWA's casual 
    dismissal of determinations required by various statutes and Executive 
    Orders. In comments on the NPRM, the WTA argued that a long-term effect 
    of any freeze would be to prohibit the natural evolution of technology 
    in the trucking industry. Such a situation, in turn, would be likely to 
    cause major and significant impacts on competing transportation modes, 
    related businesses, and the general public. Accordingly, the WTA 
    insisted that the FHWA conduct (1) a full regulatory evaluation, (2) a 
    full economic assessment, (3) a federalism assessment, and (4) an 
    environmental impact study.
    
    Effects on Small Entities and Other Economic Issues
    
        After undertaking the analysis required by the Regulatory 
    Flexibility Act (5 U.S.C. 601-612), the FHWA reiterated in the SNPRM 
    its conclusion that this rulemaking would not have a significant 
    economic impact on a substantial number of small entities. This 
    conclusion remains unchanged in this final rule. The WTA, responding to 
    an earlier document, stated that ``there is no question that the form 
    and substance of this NPRM are clearly harmful to small entities. Most 
    businesses affected in Wyoming are small entities. The few large 
    entities doing business in Wyoming are similarly adversely affected.''
        This rule in no way restricts the ability of small entities to 
    enter the LCV segment of the motor carrier industry. The LCV segment of 
    the industry can expand as rapidly as it finds customers. Neither the 
    rule nor any State affected by the rule limits the number of LCV's that 
    may be placed in service, or the number of motor carriers that may 
    operate them. The rule does not reduce the highway network on which 
    carriers may run LCV's; it simply lists the routes where the States 
    have decided very large vehicles can operate without seriously damaging 
    pavements and bridges. In Wyoming, that amounts to every NN route in 
    the State.
        The WTA seems to be demanding, not better regulatory analyses, but 
    something like a full-scale econometric model of the transportation 
    segment of the economy. The WTA apparently believes that such a model, 
    when run, would demonstrate that the ISTEA freeze is likely to change 
    the competitive balance between railroad and highway transportation, 
    retard the technological development of trucks, reduce employment in 
    the motor carrier industry, and raise freight costs.
        Because the LCV freeze includes all State routes currently in use, 
    and because we are not aware that any State wishes to expand its LCV 
    network, we expect that the freeze will have none of the effects 
    predicted by the WTA, at least in the short term. The FHWA believes 
    that the ``frozen'' LCV Network offers ample opportunity for reasonable 
    growth. Insufficient data exist to evaluate the possible longer-term 
    effects of this rulemaking, and any conclusions presented here would be 
    speculative in nature.
    
    Environmental Issues
    
        In considering this rulemaking action from the perspective of the 
    National Environmental Policy Act of 1969 (42 U.S.C. 4321 et seq.) 
    (NEPA), the FHWA has twice found that it would have no effect on the 
    quality of the environment. The WTA disagreed: ``A rule which dictates 
    increased use of fuels, a scarce natural resource, affects the quality 
    of the environment in a negative fashion.'' The rule does not dictate 
    increased use of fuels. If LCV's move freight at a lower fuel or 
    emission cost per ton/mile than other motor vehicles, as the WTA 
    appears to believe, the rule would not prevent LCV's from displacing 
    less efficient vehicles. The FHWA sees no reason to change its 
    conclusion.
    
    Changes to Part 658--National Network
    
        As discussed earlier, this final rule makes two technical 
    amendments to appendix A, 23 CFR part 658, which lists federally-
    designated routes on the NN. These changes would amend the listings for 
    California, to reflect the inclusion of the I-580 Richmond-San Rafael 
    Bridge in the NN, and also for Virginia, to reflect that State's new 
    milepost-based exit numbering system. For the reasons set forth earlier 
    in this document, the FHWA has determined that prior notice and 
    opportunity for comment are not required for either amendment under the 
    U.S. Department of Transportation's Regulatory Policies and Procedures, 
    as it is not anticipated that such action will result in the receipt of 
    useful information.
    
    Executive Order 12866 (Regulatory Planning and Review) and DOT 
    Regulatory Policies and Procedures
    
        The FHWA has determined that this action is not a significant 
    regulatory action within the meaning of Executive Order 12866 or 
    significant within the meaning of U.S. Department of Transportation 
    Regulatory Policies and Procedures. It is anticipated that the economic 
    impact of this rulemaking will be minimal; therefore, a regulatory 
    evaluation is not required.
    
    Regulatory Flexibility Act
    
        In compliance with the Regulatory Flexibility Act, the FHWA has 
    evaluated the effects of this rule on small entities. Based on the 
    evaluation, the FHWA hereby certifies that this action will not have a 
    significant economic impact on a substantial number of small entities. 
    This action merely lists applicable limitations by specific vehicle 
    configuration, by State, in effect on June 1, 1991, and will not 
    further restrict the operation of any vehicle in lawful operation on or 
    before June 1, 1991, which is subject to those limitations.
    
    Executive Order 12612 (Federalism Assessment)
    
        This action has been analyzed in accordance with the principles and 
    criteria contained in Executive Order 12612, and it has been determined 
    that this action does not have sufficient federalism implications to 
    warrant the preparation of a federalism assessment. Although its effect 
    will be to prevent the expansion of the ISTEA vehicle network beyond 
    that which States allowed on June 1, 1991, that is a direct result of 
    the underlying statute. Moreover, there is no indication at this time 
    that the States planned any significant expansion of that network which 
    would be impeded by this requirement. This action merely implements 
    requirements of the ISTEA.
    
    Executive Order 12372 (Intergovernmental Review)
    
        Catalog of Federal Domestic Assistance Program Number 20.217, Motor 
    Carrier Safety. The regulations implementing Executive Order 12372 
    regarding intergovernmental consultation on Federal programs and 
    activities do not apply to this program.
    
    Paperwork Reduction
    
        This action does not contain an additional or expanded collection 
    of information requirement for purposes of the Paperwork Reduction Act 
    of 1980, 44 U.S.C. 3501 et seq. Data collection necessary for the 
    States to be able to certify enforcement of State size and weight laws 
    currently operates under OMB approval number 2125-0034.
    
    National Environmental Policy Act
    
        The FHWA has analyzed this action for the purpose of the NEPA and 
    has determined that this action would not have any effect on the 
    quality of the environment.
    
    Regulation Identification Number
    
        A regulation identification number (RIN) is assigned to each 
    regulatory action listed in the Unified Agenda of Federal Regulations. 
    The Regulatory Information Service Center publishes the Unified Agenda 
    in April and October of each year. The RIN contained in the heading of 
    this document can be used to cross reference this action with the 
    Unified Agenda.
    
    List of Subjects in 23 CFR Parts 657 and 658
    
        Grant programs--transportation, Highways and roads, and Motor 
    carrier size and weight.
    
        Issued on: May 27, 1994.
    Rodney E. Slater,
    Federal Highway Administrator.
    
        In consideration of the foregoing, the FHWA is amending 23 CFR, 
    subchapter G, parts 657 and 658 as set forth below.
    
    PART 657--CERTIFICATION OF SIZE AND WEIGHT ENFORCEMENT
    
        1. The authority citation for 23 CFR part 657 is revised to read as 
    follows:
    
        Authority: Sec. 123, Pub. L. 95-599, 92 Stat. 2689; 23 U.S.C. 
    127, 141, and 315; 49 U.S.C. app. 2311, 2312, and 2316; sec. 1023, 
    Pub. L. 102-240, 105 Stat. 1914; and 49 CFR 1.48(b)(19), (b)(23), 
    (c)(1), and (c)(19).
    
        2. Section 657.11 is revised to read as follows:
    
    
    Sec. 657.11  Evaluation of operations.
    
        (a) The State shall submit its enforcement plan or annual update to 
    the Office of Motor Carriers in the FHWA division office by July 1 of 
    each year. However, if a State's legislative or budgetary cycle is not 
    consonant with that date, the FHWA and the State may jointly select an 
    alternate date. In any event, a State must have an approved plan in 
    effect by October 1 of each year. Failure of a State to submit or 
    update a plan will result in the State being unable to certify in 
    accordance with Sec. 657.13 for the period to be covered by the plan.
        (b) The Office of Motor Carriers in the FHWA division office shall 
    review the State's operation under the accepted plan on a continuing 
    basis and shall prepare an evaluation report annually. The State will 
    be advised of the results of the evaluation and of any needed changes 
    either in the plan itself or in its implementation. Copies of the 
    evaluation report and subsequent modifications resulting from the 
    evaluation shall be forwarded through the Regional Director of Motor 
    Carriers to the Washington, D.C., Headquarters office.
        3. Section 657.13 is revised to read as follows:
    
    
    Sec. 657.13  Certification requirement.
    
        Each State shall certify to the Federal Highway Administrator, 
    before January 1 of each year, that it is enforcing all State laws 
    respecting maximum vehicle size and weight permitted on what, prior to 
    October 1, 1991, were the Federal-aid Primary, Secondary, and Urban 
    Systems, including the Interstate System, in accordance with 23 U.S.C. 
    127. The States must also certify that they are enforcing and complying 
    with the ISTEA freeze on the use of LCV's and other multi-unit 
    vehicles. The certification shall be supported by information on 
    activities and results achieved during the preceding 12-month period 
    ending on September 30 of each year.
        4. Section 657.15 is revised to read as follows:
    
    
    Sec. 657.15  Certification content.
    
        The certification shall consist of the following elements and each 
    element shall be addressed even though the response is negative:
        (a) A statement by the Governor of the State, or an official 
    designated by the Governor, that the State's vehicle weight laws and 
    regulations governing use of the Interstate System conform to 23 U.S.C. 
    127.
        (b) A statement by the Governor of the State, or an official 
    designated by the Governor, that all State size and weight limits are 
    being enforced on the Interstate System and those routes which prior to 
    October 1, 1991, were designated as part of the Federal-aid Primary, 
    Urban, and Secondary Systems, and that the State is enforcing and 
    complying with the provisions of 23 U.S.C. 127(d) and 49 U.S.C. app. 
    2311(j). Urbanized areas not subject to State jurisdiction shall be 
    identified. The statement shall include an analysis of enforcement 
    efforts in such areas.
        (c) Except for Alaska and Puerto Rico, the certifying statements 
    required by paragraphs (a) and (b) of this section shall be worded as 
    follows (the statements for Alaska and Puerto Rico do not have to 
    reference 23 U.S.C. 127(d) in (c)(2), or include paragraph (c)(3) of 
    this section):
    
        I, (name of certifying official), (position title), of the State 
    of ______________ do hereby certify:
    
        (1) That all State laws and regulations governing vehicle size and 
    weight are being enforced on those highways which, prior to October 1, 
    1991, were designated as part of the Federal-aid Primary, Federal-aid 
    Secondary, or Federal-aid Urban Systems;
        (2) That the State is enforcing the freeze provisions of the 
    Intermodal Surface Transportation Efficiency Act of 1991 (23 U.S.C. 
    127(d) and 49 U.S.C. app. 2311(j)); and
        (3) That all State laws governing vehicle weight on the Interstate 
    System are consistent with 23 U.S.C. 127 (a) and (b).
        (d) If this statement is made by an official other than the 
    Governor, a copy of the document designating the official, signed by 
    the Governor, shall also be included in the certification made under 
    this part.
        (e) A copy of any State law or regulation pertaining to vehicle 
    sizes and weights adopted since the State's last certification and an 
    analysis of the changes made. Those laws and regulations pertaining to 
    special permits and penalties shall be specifically identified and 
    analyzed in accordance with section 123 of the Surface Transportation 
    Assistance Act of 1978 (Pub. L. 95-599).
        (f) A report of State size and weight enforcement efforts during 
    the period covered by the certification which addresses the following:
        (1) Actual operations as compared with those forecast by the plan 
    submitted earlier, with particular attention to changes in or 
    deviations from the operations proposed.
        (2) Impacts of the process as actually applied, in terms of changes 
    in the number of oversize and/or overweight vehicles.
        (3) Measures of activity--(i) Vehicles weighed. Separate totals 
    shall be reported for the annual number of vehicles weighed on fixed 
    scales, on semiportable scales, on portable scales, and on WIM when 
    used for enforcement.
        (ii) Penalties. Penalties reported shall include citations issued, 
    civil assessments, and incidences of load shifting or off-loading of 
    excess weight categorized as follows: violations of axle and/or gross 
    vehicle weights, or violations resulting from application of the bridge 
    formula.
        (iii) Permits. The number of permits issued for overweight loads 
    shall be reported. The reported numbers shall specify permits for 
    divisible and nondivisible loads and whether issued on a trip or annual 
    basis. Permits issued for excess height, length, or width need not be 
    reported except where issued for the overwidth movement of a divisible 
    load.
        5. Section 657.17 is revised to read as follows:
    
    
    Sec. 657.17   Certification submittal.
    
        (a) The Governor, or an official designated by the Governor, shall 
    submit the certification to the Office of Motor Carriers in the FHWA 
    division office prior to January 1 of each year.
        (b) The Office of Motor Carriers in the FHWA division office shall 
    forward the original certification to the Associate Administrator for 
    Motor Carriers and one copy to the Office of Chief Counsel. Copies of 
    appropriate evaluations and/or comments shall accompany any 
    transmittal.
    
    PART 658--TRUCK SIZE AND WEIGHT, ROUTE DESIGNATIONS--LENGTH, WIDTH, 
    AND WEIGHT LIMITATIONS
    
        6. The authority citation for 23 CFR part 658 is revised to read as 
    follows:
    
        Authority: 23 U.S.C. 127 and 315; 49 U.S.C. app. 2311, 2312, and 
    2316; 49 CFR 1.48(b)(19) and (c)(19).
    
        7. Section 658.1 is revised to read as follows:
    
    
    Sec. 658.1   Purpose.
    
        The purpose of this part is to identify a National Network of 
    highways available to vehicles authorized by provisions of the Surface 
    Transportation Assistance Act of 1982 (STAA) as amended, and to 
    prescribe national policies that govern truck and bus size and weight.
        8. Section 658.5 is amended by removing the arabic letter paragraph 
    designations from all definitions, placing the definitions in 
    alphabetical order, revising two existing definitions, and adding six 
    new definitions in appropriate order. The added and revised definitions 
    read as follows:
    
    
    Sec. 658.5   Definitions.
    
    * * * * *
        Beverage semitrailer. A van-type, drop-frame semitrailer designed 
    and used specifically for the transport and delivery of bottled or 
    canned beverages (i.e., liquids for drinking, including water) which 
    has side-only access for loading and unloading this commodity. 
    Semitrailer has the same meaning as in 49 CFR 390.5.
    * * * * *
        Cargo-carrying unit. As used in this part, cargo-carrying unit 
    means any portion of a commercial motor vehicle (CMV) combination 
    (other than a truck tractor) used for the carrying of cargo, including 
    a trailer, semitrailer, or the cargo-carrying section of a single-unit 
    truck.
    * * * * *
        Federal-aid Primary System. The Federal-aid Highway System of rural 
    arterials and their extensions into or through urban areas in existence 
    on June 1, 1991, as described in 23 U.S.C. 103(b) in effect at that 
    time.
    * * * * *
        Longer combination vehicle (LCV). As used in this part, longer 
    combination vehicle means any combination of a truck tractor and two or 
    more trailers or semitrailers which operates on the Interstate System 
    at a gross vehicle weight greater than 80,000 pounds.
    * * * * *
        Maxi-cube vehicle. A maxi-cube vehicle is a combination vehicle 
    consisting of a power unit and a trailing unit, both of which are 
    designed to carry cargo. The power unit is a nonarticulated truck with 
    one or more drive axles that carries either a detachable or a 
    permanently attached cargo box. The trailing unit is a trailer or 
    semitrailer with a cargo box so designed that the power unit may be 
    loaded and unloaded through the trailing unit. Neither cargo box shall 
    exceed 34 feet in length, excluding drawbar or hitching device; the 
    distance from the front of the first to the rear of the second cargo 
    box shall not exceed 60 feet, including the space between the cargo 
    boxes; and the overall length of the combination vehicle shall not 
    exceed 65 feet, including the space between the cargo boxes.

        Motor carrier of passengers. As used in this part, a motor carrier 
    of passengers is a common, contract, or private carrier using a bus to 
    provide commercial transportation of passengers. Bus has the same 
    meaning as in 49 CFR 390.5.
    * * * * *
        National Network (NN). The composite of the individual network of 
    highways from each State on which vehicles authorized by the provisions 
    of the STAA are allowed to operate. The network in each State includes 
    the Interstate System, exclusive of those portions excepted under 
    Sec. 658.11(f) or deleted under Sec. 658.11(d), and those portions of 
    the Federal-aid Primary System in existence on June 1, 1991, set out by 
    the FHWA in appendix A to this part.

        Nondivisible load or vehicle.
        (1) As used in this part, nondivisible means any load or vehicle 
    exceeding applicable length or weight limits which, if separated into 
    smaller loads or vehicles, would:
        (i) Compromise the intended use of the vehicle, i.e., make it 
    unable to perform the function for which it was intended;
        (ii) Destroy the value of the load or vehicle, i.e., make it 
    unusable for its intended purpose; or
        (iii) Require more than 8 workhours to dismantle using appropriate 
    equipment. The applicant for a nondivisible load permit has the burden 
    of proof as to the number of workhours required to dismantle the load.
        (2) A State may treat emergency response vehicles and casks 
    designed and used for the transport of spent nuclear materials as 
    nondivisible vehicles or loads.

        10. In Sec. 658.13, paragraphs (d), (e), and (f) are redesignated 
    as paragraphs (e), (f), and (g), respectively, a new paragraph (d) is 
    added, and new paragraphs (e)(4) and (e)(5) are added under 
    redesignated paragraph (e) to read as follows:
    
    
    Sec. 658.13   Length.
    
    * * * * *
        (d) No State shall impose a limit of less than 45 feet on the 
    length of any bus on the NN.
        (e) * * *
        (4) Maxi-cube vehicle. No State shall impose a length limit on a 
    maxi-cube vehicle, as defined in Sec. 658.5 of this part, of less than 
    34 feet on either cargo box, excluding drawbar or hitching device; 60 
    feet on the distance from the front of the first to the rear of the 
    second cargo box, including the space between the cargo boxes; or 65 
    feet on the overall length of the combination, including the space 
    between the cargo boxes. The measurement for compliance with the 60- 
    and 65-foot distance shall include the actual distance between cargo 
    boxes, measured along the centerline of the drawbar or hitching device. 
    For maxi-cubes with an adjustable length drawbar or hitching device, 
    the 60- and 65-foot distances shall be measured with a drawbar spacing 
    of not more than 27 inches. The drawbar may be temporarily extended 
    beyond that distance to maneuver or load the vehicle.
        (5) Beverage semitrailer. (i) A beverage semitrailer is specialized 
    equipment if it has an upper coupler plate that extends beyond the 
    front of the semitrailer, but not beyond its swing radius, as measured 
    from the center line of the kingpin to a front corner of the 
    semitrailer, which cannot be used for carrying cargo other than the 
    structure of the semitrailer, and with the center line of the kingpin 
    not more than 28 feet from the rear of the semitrailer (exclusive of 
    rear-mounted devices not measured in determining semitrailer length). 
    No State shall impose an overall length limit on such vehicles when 
    operating in a truck tractor-beverage semitrailer or truck tractor-
    beverage semitrailer-beverage trailer combination on the NN.
        (ii) The beverage trailer referred to in paragraph (e)(5)(i) of 
    this section means a beverage semitrailer and converter dolly. 
    Converter dolly has the same meaning as in 49 CFR 393.5.
        (iii) Truck tractor-beverage semitrailer combinations shall have 
    the same access to points of loading and unloading as 28-foot 
    semitrailers (28.5-foot where allowed by Sec. 658.13) in 23 CFR 658.19.
    * * * * *
        11. In Sec. 658.17, paragraphs (f), (g), and (h) are redesignated 
    as paragraphs (g), (h), and (i), respectively; new paragraphs (f), (j), 
    and (k) are added; and redesignated paragraph (h) is revised. 
    Paragraphs (f) through (k) now read as follows:
    
    
    Sec. 658.17  Weight.
    
    * * * * *
        (f) Except as provided herein, States may not enforce on the 
    Interstate System vehicle weight limits of less than 20,000 pounds on a 
    single axle, 34,000 pounds on a tandem axle, or the weights derived 
    from the Bridge Formula, up to a maximum of 80,000 pounds, including 
    all enforcement tolerances. States may not limit tire loads to less 
    than 500 pounds per inch of tire or tread width, except that such 
    limits may not be applied to tires on the steering axle. States may not 
    limit steering axle weights to less than 20,000 pounds or the axle 
    rating established by the manufacturer, whichever is lower.
        (g) The weights in paragraphs (b), (c), (d), and (e) of this 
    section shall be inclusive of all tolerances, enforcement or otherwise, 
    with the exception of a scale allowance factor when using portable 
    scales (wheel-load weighers). The current accuracy of such scales is 
    generally within 2 or 3 percent of actual weight, but in no case shall 
    an allowance in excess of 5 percent be applied. Penalty or fine 
    schedules which impose no fine up to a specified threshold, i.e., 1,000 
    pounds, will be considered as tolerance provisions not authorized by 23 
    U.S.C. 127.
        (h) States may issue special permits without regard to the axle, 
    gross, or Federal Bridge Formula requirements for nondivisible vehicles 
    or loads.
        (i) The provisions of paragraphs (b), (c), and (d) of this section 
    shall not apply to single-, or tandem-axle weights, or gross weights 
    legally authorized under State law on July 1, 1956. The group of axles 
    requirements established in this section shall not apply to vehicles 
    legally grandfathered under State groups of axles tables or formulas on 
    January 4, 1975.
        (j) The provisions of paragraphs (c) through (e) of this section 
    shall not apply to the operation on Interstate Route 68 in Allegany and 
    Garrett Counties, Maryland, of any specialized vehicle equipped with a 
    steering axle and a tridem axle and used for hauling coal, logs, and 
    pulpwood if such vehicle is of a type of vehicle as was operating in 
    such counties on U.S. Routes 40 or 48 for such purposes on August 1, 
    1991.
        (k) Beginning October 6, 1992, and ending October 5, 1994, the 
    provisions of paragraphs (c) through (e) of this section shall not 
    apply to any vehicle which is regularly and exclusively used as an 
    intrastate public agency transit passenger bus. The Secretary may 
    extend this temporary exemption for an additional year.
        12. In Sec. 658.19, paragraph (a) is revised to read as follows:
    
    
    Sec. 658.19  Reasonable access.
    
        (a) No State may enact or enforce any law denying reasonable access 
    to vehicles with dimensions authorized by the STAA between the NN and 
    terminals and facilities for food, fuel, repairs, and rest. In 
    addition, no State may enact or enforce any law denying reasonable 
    access between the NN and points of loading and unloading to household 
    goods carriers, motor carriers of passengers, and any truck tractor-
    semitrailer combination in which the semitrailer has a length not to 
    exceed 28 feet (28.5 feet where allowed pursuant to Sec. 658.13(b)(5) 
    of this part) and which generally operates as part of a vehicle 
    combination described in Secs. 658.13(b)(5) and 658.15(a) of this part.
    * * * * *
        13. Part 658 is amended by adding Sec. 658.23 as follows:
    
    
    Sec. 658.23  LCV freeze; cargo-carrying unit freeze.
    
        (a) (1) Except as otherwise provided in this section and except for 
    tow trucks with vehicles in tow, a State may allow the operation of 
    LCV's on the Interstate System only as listed in appendix C to this 
    part.
        (2) Except as otherwise provided in this section, a State may not 
    allow the operation on the NN of any CMV combination with two or more 
    cargo-carrying units (not including the truck tractor) whose cargo-
    carrying units exceed:
        (i) The maximum combination trailer, semitrailer, or other type of 
    length limitation authorized by State law or regulation of that State 
    on or before June 1, 1991; or
        (ii) The length of the cargo-carrying units of those CMV 
    combinations, by specific configuration, in actual, lawful operation on 
    a regular or periodic basis (including continuing seasonal operation) 
    in that State on or before June 1, 1991, as listed in appendix C to 
    this part.
        (b) Notwithstanding paragraph (a)(2) of this section, the following 
    CMV combinations with two or more cargo-carrying units may operate on 
    the NN.
        (1) Truck tractor-semitrailer-trailer and truck tractor-
    semitrailer-semitrailer combinations with a maximum length of the 
    individual cargo units of 28.5 feet or less.
        (2) Vehicles described in Sec. 658.13(e) and (g).
        (3) Truck tractor-trailer and truck tractor-semitrailer 
    combinations with an overall length of 65 feet or less.
        (4) Maxi-cubes.
        (5) Tow trucks with vehicles in tow.
        (c) For specific safety purposes and road construction, a State may 
    make minor adjustments of a temporary and emergency nature to route 
    designations and vehicle operating restrictions applicable to 
    combinations subject to sections 1023 and 4006 of Pub. L. 102-240 and 
    in effect on June 1, 1991 (July 6, 1991, for Alaska). Adjustments which 
    last 30 days or less may be made without notifying the FHWA. Minor 
    adjustments which exceed 30 days require approval of the FHWA. When 
    such adjustments are needed, a State must submit to the Division Office 
    of Motor Carriers, by the end of the 30th day, a written description of 
    the emergency, the date on which it began, and the date on which it is 
    expected to conclude. If the adjustment involves route designations, 
    the State shall describe the new route on which vehicles otherwise 
    subject to the freeze imposed by sections 1023 and 4006 of Pub. L. 102-
    240 are allowed to operate. To the extent possible, the geometric and 
    pavement design characteristics of the alternate route should be 
    equivalent to those of the highway section which is temporarily 
    unavailable. Approval or disapproval by Office of Motor Carriers 
    officials of adjustments involving route designations shall be 
    coordinated with the Division Administrator. If the adjustment involves 
    vehicle operating restrictions, the State shall list the restrictions 
    that have been removed or modified. Approval or disapproval of the 
    adjustment by the Division Office of Motor Carriers shall take place 
    only after consultation with the Regional Office of Motor Carriers. If 
    the adjustment is approved, a copy of the approved submission shall be 
    forwarded through the Regional Office of Motor Carriers, to the 
    Associate Administrator for Motor Carriers at Headquarters, who will 
    publish the notice of adjustment, with an expiration date, in the 
    Federal Register. Requests for extensions of time beyond the originally 
    established conclusion date shall be subject to the same approval and 
    publication process as the original request. If upon consultation with 
    the Regional Office of Motor Carriers, a decision is reached that minor 
    adjustments made by a State are not legitimately attributable to road 
    or bridge construction or safety, the Division Office of Motor Carriers 
    will so inform the State, and the original conditions of the freeze 
    must be reimposed immediately. Failure to do so may subject the State 
    to a penalty pursuant to 23 U.S.C. 141.
        (d) A State may issue a permit authorizing a CMV to transport an 
    overlength nondivisible load on two or more cargo-carrying units on the 
    NN without regard to the restrictions in Sec. 658.23(a)(2).
        (e) States further restricting or prohibiting the operation of 
    vehicles subject to sections 1023 and 4006 of Public Law 102-240 after 
    June 1, 1991, shall notify the FHWA Division Office of Motor Carriers 
    within 30 days after the restriction is effective. The Division Office 
    of Motor Carriers shall forward the information through the Regional 
    Office of Motor Carriers to the Associate Administrator for Motor 
    Carriers at Headquarters. The FHWA will publish the restriction in the 
    Federal Register as an amendment to appendix C to this part. Failure to 
    provide such notification may subject the State to a penalty pursuant 
    to 23 U.S.C. 141.
        (f) The Federal Highway Administrator, on his or her own motion or 
    upon a request by any person (including a State), shall review the 
    information set forth in appendix C to this part. If the Administrator 
    determines there is cause to believe that a mistake was made in the 
    accuracy of the information contained in appendix C to this part, the 
    Administrator shall commence a proceeding to determine whether the 
    information published should be corrected. If the Administrator 
    determines that there is a mistake in the accuracy of the information 
    contained in appendix C to this part, the Administrator shall publish 
    in the Federal Register the appropriate corrections to reflect that 
    determination.
        14. Appendix A to part 658 is amended in the entry for the State of 
    California by removing Note 1 and redesignating Note 2, and by revising 
    the entry for the State of Virginia to read as follows:

        15. Part 658 is amended by adding appendix C to read as follows:
    
    Appendix C to Part 658--Trucks over 80,000 Pounds on the Interstate 
    System and Trucks over STAA Lengths on the National Network
    
        This appendix contains the weight and size provisions that were in 
    effect on or before June 1, 1991 (July 6, 1991 for Alaska), for 
    vehicles covered by 23 U.S.C. 127(d) (LCV's) and 49 U.S.C. app. 2311(j) 
    (commercial motor vehicles (CMV's) with 2 or more cargo-carrying 
    units). Weights and dimensions are ``frozen'' at the values shown here, 
    which were in effect on June 1, 1991 (Alaska, July 6, 1991). All 
    vehicles are listed by configuration type.
    Trucks Over 80,000 Pounds on the Interstate System
        In the State-by-State descriptions, CMV combinations which can also 
    be LCV's are identified with the letters ``LCV'' following the type of 
    combination vehicle. The maximum allowable gross vehicle weight is 
    given in this appendix (in thousands of pounds indicated by a ``K''), 
    as well as information summarizing the operational conditions, routes, 
    and legal citations. The term ``Interstate System'' as used herein 
    refers to the Dwight D. Eisenhower System of Interstate and Defense 
    Highways.
    Trucks Over STAA Lengths on the National Network
        Listed for each State by combination type is either:
        1. The maximum cargo-carrying length (shown in feet); or
        2. A notation that such vehicle is not allowed (indicated by a 
    ``NO'').
        CMV's are categorized as follows:
        1. A CMV combination consisting of a truck tractor and two trailing 
    units.
        2. A CMV combination consisting of a truck tractor and three 
    trailing units.
        3. CMV combinations with two or more cargo-carrying units not 
    included in descriptions 1 or 2.
        In the following table the top number is the maximum cargo-carrying 
    length measured in feet from the front of the first cargo unit to the 
    rear of the last cargo unit. This distance is not to include length 
    exclusive devices which have been approved by the Secretary or by any 
    State. Devices excluded from length determination shall only include 
    items whose function is related to the safe and efficient operation of 
    the semitrailer or trailer. No device excluded from length 
    determination shall be designed or used for carrying cargo. The number 
    below the length measurement is the maximum gross weight in thousands 
    of pounds that the type of vehicle can carry when operating as an LCV 
    on the Interstate System. For every State where there is a length or 
    weight number in the table that follows, additional information is 
    provided.
    
                                    Vehicle Combinations Subject to Pub. L. 102-240

    (1)--State submission includes multiple vehicles in this category--see individual State listings.               
    (2)--No maximum weight is established as this vehicle combination is not considered an ``LCV'' per the ISTEA    
      definition. Florida's combination is not allowed to operate on the Interstate System, and the combinations for
      Hawaii, Mississippi, and Nebraska are not allowed to exceed 80,000 pounds.                                    
    (3)--No maximum cargo-carrying length is established for this combination. Because State law limits each        
      trailing unit to not more than 28.5 feet in length, this combination is allowed to operate on all NN routes   
      under the authority of the STAA of 1982, regardless of actual cargo-carrying length. The maximum weight listed
      is New Mexico's maximum allowable gross weight on the Interstate System under the grandfather authority of 23 
      U.S.C. 127.                                                                                                   
    
        The following abbreviation convention is used throughout the 
    narrative State-by-State descriptions for the captions OPERATIONAL 
    CONDITIONS, ROUTES, and LEGAL CITATIONS: two letter State abbreviation, 
    dash, ``TT'' for truck tractor, and 2 or 3 for two or three trailing 
    units. For example, the phrase ``Arizona truck tractor and 2 trailing 
    units'', would be noted as ``AZ-TT2''; the phrase ``Indiana truck 
    tractor and 3 trailing units'' would be noted as ``IN-TT3'', etc.
    
    STATE: ALASKA
    
    COMBINATION: Truck tractor and 2 trailing units
    LENGTH OF THE CARGO-CARRYING UNITS: 95 feet
    OPERATIONAL CONDITIONS:
        WEIGHT: The combination must be in compliance with State laws and 
    regulations. There are no highways in the State subject to Interstate 
    System weight limits. Therefore, the ISTEA freeze as it applies to 
    maximum weight is not applicable.
        DRIVER: The driver must have a commercial driver's license with the 
    appropriate endorsement.
        VEHICLE: Combinations with an overall length greater than 75 feet, 
    measured bumper to bumper, must display an ``OVERSIZE## warning sign on 
    the front and rear. In combinations where one cargo-carrying unit is 
    more than 5,000 pounds heavier than the other, the heavier unit shall 
    be placed immediately behind the power unit. Weather restrictions are 
    imposed when hazardous conditions exist, as determined by the Alaska 
    Department of Transportation and Public Facilities (DOT&PF) and the 
    Alaska Department of Public Safety, Division of State Troopers. Time of 
    day travel is not restricted.
        PERMIT: None required.
        ACCESS: Alaska allows reasonable access not to exceed 5 miles to 
    reach or return from terminals and facilities for food, fuel, or rest. 
    The most direct route must be used. The Commissioner of the Alaska 
    DOT&PF may allow access to specific routes if it can be shown that 
    travel frequency, necessity, and route accommodation are required.

        ACCESS: A vehicle shall not be operated off the designated portions 
    of the Interstate System except to access food, fuel, repairs, and rest 
    or to access a facility. Access to a facility shall be subject to the 
    following conditions:
        (1) The facility must:
        (a) Be either a manufacturing or a distribution center, a 
    warehouse, or truck terminal located in an area where industrial uses 
    are permitted;
        (b) Be a construction site; and
        (c) Meet the following criteria:
        1 vehicles are formed for transport or broken down for delivery on 
    the premises;
        2 adequate off-roadway space exists on the premises to safely 
    maneuver the vehicles; and
        3 adequate equipment is available on the premises to handle, load, 
    and unload the vehicle, its trailers, and cargo.
        (2) The facility must be located within a maximum distance of 10 
    miles from the point where the vehicle enters or exits the designated 
    portions of the Interstate System. Such 10-mile distance shall be 
    measured by the actual route(s) to be traveled to the facility, rather 
    than by a straight line radius from the designated Interstate System to 
    the facility;
        (3) The access route(s) between the designated Interstate System 
    and the facility must be approved in advance by the public entity 
    (Colorado DOT, municipality, or county) having jurisdiction for the 
    roadway(s) that make up the route(s). Where the State of Colorado has 
    jurisdiction over the access route(s), it will consider the following 
    safety, engineering, and other criteria in determining whether to 
    approve the route(s):
        (a) Safety of the motoring public;
        (b) Geometrics of the street and roadway;
        (c) Traffic volumes and patterns;
        (d) Protection of State highways, roadways, and structures;
        (e) Zoning and general characteristics of the route(s) to be 
    encountered; and
        (f) Other relevant criteria warranted by special circumstances of 
    the proposed route(s).
        Local entities, counties, and municipalities having jurisdiction 
    over route(s), should consider similar criteria in determining whether 
    to approve the proposed ingress and egress route(s); and
        (4) A permit holder shall access only the facility or location 
    authorized by the permit. If the permit authorizes more than one 
    facility or location, then on any single trip by an LVC from the 
    designated Interstate System the permit holder may access only one 
    facility or location before returning to the designated Interstate 
    System.

    COMBINATION: Truck tractor and 3 trailing units--LCV
    LENGTH OF THE CARGO-CARRYING UNITS: 109 feet
    MAXIMUM ALLOWABLE GROSS WEIGHT: 120,000 pounds
        OPERATIONAL CONDITIONS: The operations of triple trailing unit 
    combinations are governed by two sets of criteria: (1) The Turnpike and 
    Turnpike access rules, and (2) the SVC rules which apply off of the 
    Turnpike except in the case of vehicles operating under Turnpike access 
    authority. The Turnpike and Turnpike access rules allow a maximum 
    combination vehicle length of 119 feet overall. The SVC rules require 
    ``Triples'' to have trailers of no more than 28.5 feet maximum length 
    or a cargo-carrying length of approximately 95 feet.
        The Turnpike and Turnpike access rules have no time-of-day travel 
    restrictions or other special requirements.
        The SVC rules have several operational conditions. SVC's cannot 
    operate on holidays or during holiday weekends. SVC's cannot be 
    dispatched or operated during adverse weather conditions. SVC's must 
    travel in the right lane, except for passing, and the following 
    distance is 100 feet for every 10 miles per hour. SVC permits can 
    include any restrictions deemed necessary, including specific routes 
    and hours, days, and/or seasons of operation. Rules and regulations can 
    be promulgated regarding driver qualifications, vehicle equipment, and 
    operational standards.
        WEIGHT: All triple trailing unit combinations must comply with the 
    Federal Bridge Formula with maximum axle weights of 20,000 pounds on a 
    single axle and 34,000 pounds on a tandem axle. The maximum gross 
    weight is 120,000 pounds on the Turnpike and Turnpike access routes, 
    but the SVC's have a maximum weight of 110,000 pounds.
        DRIVER: A commercial driver's license with the appropriate 
    endorsement is required under both Turnpike and SVC rules. In addition, 
    for SVC operation drivers must have completed SVC driver training and a 
    company road test. Drivers must also have 2 years of experience driving 
    tractor-semitrailers and 1 year driving doubles.
        VEHICLE: Vehicle requirements apply to the SVC program only. All 
    axles, except steering axles, must have dual wheels, and all vehicles 
    must be able to achieve and maintain a speed of 40 miles per hour on 
    all grades. Antispray mud flaps shall be attached to the rear of each 
    axle except the steering axle. Mud flaps shall have a surface designed 
    to absorb and deflect excess moisture to the road surface. Drop and 
    lift axles are prohibited. Vehicles may have a minimum of six and a 
    maximum of nine axles. The heaviest trailers are to be placed forward. 
    Hazardous cargo is prohibited. Convex mirrors are required on both 
    sides of the cab. Equipment must comply with the requirements of 49 CFR 
    390-399.
        Any SVC shall be stable at all times during normal braking and 
    normal operation. When traveling on a level, smooth paved surface, an 
    SVC shall follow the towing vehicle without shifting or swerving beyond 
    the restraints of the lane of travel.
        PERMIT: Same as the KS-TT2 combination on the Turnpike and Turnpike 
    access routes. A fee per company plus a permit fee for each power unit 
    is required for the SVC program, and the SVC permits are valid for 1 
    year. SVC's operated pursuant to regulation 36-1-33 under an annual 
    permit shall be covered by insurance.
        ACCESS: Turnpike access routes include all routes between the 
    Turnpike and a motor freight terminal located within a 10-mile radius 
    of each toll booth, except at the northeastern end of the Turnpike 
    where a 20-mile radius is allowed. SVC access routes include all routes 
    between the Interstate and a motor freight terminal located within 5 
    miles of the Interstate at Goodland.

    or combination of vehicles used in tandem-trailer operations as a 
    minimum shall comply with Federal Motor Carrier Safety Regulations in 
    49 CFR part 393. In addition, any vehicle, dolly converter or 
    combination of vehicles used in tandem-trailer operations shall meet 
    the requirements of the provisions of the Massachusetts Motor Vehicle 
    Law. Tandem-trailer combinations certified on or after June 1, 1968, 
    shall be equipped with suitable devices to accelerate application and 
    release of the brakes of the towed vehicle.
        (2) Axles. A tractor used to haul a tandem trailer combination with 
    a gross weight of more than 110,000 pounds shall be equipped with 
    tandem rear axles, each of which shall be engaged to bear its full 
    share of the load on the roadway surface.
        (3) Tandem Assembly. When the gross weight of the trailers vary by 
    more than 20 percent, they shall be coupled with the heaviest trailer 
    attached to the tractor. Coupling devices and towing devices shall 
    comply with the Federal regulations as stated in 49 CFR part 393. When 
    the distance between the rear of the one semitrailer and the front of 
    the following semitrailer is 10 feet or more, the dolly shall be 
    equipped with a device, or the trailers shall be connected along the 
    sides with suitable material, which will indicate to other Turnpike 
    users that the trailers are connected and are in effect one unit. The 
    MTA shall approve the devices or connections to be used on the 
    semitrailers that would indicate it is one unit. Coupling devices shall 
    be so designed, constructed, and installed, and the vehicles in a 
    tandem trailer combination shall be so designed and constructed to 
    ensure that when traveling on a level, smooth paved surface they will 
    follow in the path of the towing vehicle without shifting or swerving 
    over 3 inches to each side of the path of the towing vehicle when it is 
    moving in a straight line. A tandem trailer unit may pass another 
    vehicle traveling in the same direction only if the speed differential 
    will allow the tandem trailer unit to complete the maneuver and return 
    to the normal driving lane within a distance of 1 mile.
        Each truck tractor shall be equipped with at least one spare fuse 
    or other overload protective device, if the devices are not of a reset 
    type, for each kind and size used. The vehicle is to carry at least one 
    set of tire chains for at least one driving wheel on each side between 
    October 15 and May 1 of each year. Each truck tractor shall carry a 
    fire extinguisher which shall have an aggregate rating of 20 BC.
        PERMIT: A permittee must demonstrate to the MTA that it has 
    insurance coverage of the type and amounts required by Turnpike 
    regulation. Both the tractor manufacturer and the permittee shall 
    certify to the MTA, prior to the approval of a tractor, that it is 
    capable of hauling the maximum permissible gross load to be transported 
    by the permittee at a speed not less than 20 miles per hour on all 
    portions of the turnpike system. The MTA may revoke or temporarily 
    suspend any permit at will and the instructions of the MTA or 
    Massachusetts State Police shall be complied with immediately.
        ACCESS: Makeup and breakup areas. Tandem trailer units shall not 
    leave the Turnpike right-of-way and shall be assembled and disassembled 
    only in designated areas.

    48 feet long, the other trailer cannot exceed 42 feet. Towed vehicles 
    must not shift or sway more than 3 inches to right or left and must 
    track in a straight line on a level, smooth paved highway. Vehicles 
    must be able to accelerate and operate on a level highway at speeds 
    which are compatible with other traffic and with the speed limits and 
    must be able to maintain a minimum of 20 miles per hour on any grade on 
    which they may operate. All vehicles must have safety chains on 
    converter dollies. Vehicles must carry snow chains for each drive 
    wheel.
        Vehicle operations may be suspended in adverse weather and high 
    winds, as determined by police or the Nevada DOT.
        The shortest trailer must be in the rear of a combination unless it 
    is heavier than the longer trailer.
        Brakes must comply with all State and Federal requirements for 
    commercial vehicles including automatic braking for separation of 
    vehicles, parking brakes, and working lights.
        Vehicles must not exceed posted speed limits and cannot operate on 
    any highway on which they cannot at all times stay on the right side of 
    the center line. All LCV's must keep a distance of at least 500 feet 
    from each other.
        Every full-sized truck or truck tractor used in a combination of 
    vehicles must be equipped with at least the following emergency and 
    safety equipment:
        1. One fire extinguisher which meets ``Classification B'' of the 
    National Fire Protection Association.

    on the rear of the last vehicle in a combination of vehicles.
        3. One spare fuse for each different kind and size of fuse used in 
    every vehicle in the combination of vehicles. If the electrical system 
    of any vehicle in the combination contains any devices for protection 
    of electrical circuits from overloading, other than fuses and circuit 
    breakers which can be reset, one spare of each such device must be kept 
    as emergency and safety equipment.
        4. Any flares, reflectors or red electrical lanterns which meet 
    State or Federal law or regulation.
        Before operating a combination of vehicles on a highway of this 
    State, the owner or operator of the combination shall certify to the 
    Nevada DOT, on a form provided by it, that all vehicles and equipment 
    in the combination meet the requirements of and will be operated in 
    compliance with NAC 484.300 to 484.440, inclusive.

    COMBINATION: Truck tractor and 2 trailing units--LCV
    LENGTH OF THE CARGO-CARRYING UNITS: Not applicable
    MAXIMUM ALLOWABLE GROSS WEIGHT: 86,400 pounds
        OPERATIONAL CONDITIONS: The cargo-carrying length restriction does 
    not apply to this combination. The length of each trailing unit is 
    limited to 28.5 feet. This describes a two trailing unit vehicle whose 
    operation is guaranteed by the STAA of 1982 regardless of inter-unit 
    spacing. As long as each trailing unit is 28.5 feet long or less, 
    cargo-carrying length is not restricted. This combination is listed as 
    a LCV because it can exceed the 80,000-pound threshold established in 
    the Congressional definition. The 86,400-pound gross weight limit is 
    grandfathered for New Mexico.
        WEIGHT: Single axle = 21,600 pounds. Tandem axle = 34,200 pounds. 
    Load per inch of tire width = 600 pounds. The total gross weight with 
    load imposed on the highway by any vehicle or combination of vehicles 
    where the distance between the first and last axles is less than 19 
    feet shall not exceed that given for the respective distances in the 
    following table:

    COMBINATION: Truck tractor and 2 trailing units--LCV
    LENGTH OF THE CARGO-CARRYING UNITS: 102 feet
    MAXIMUM ALLOWABLE GROSS WEIGHT: 143,000 pounds
    OPERATIONAL CONDITIONS:
        WEIGHT: The following information pertains to tandem trailer 
    combinations with either trailer more than 28.5 feet long but not more 
    than 48 feet long. A nine-axle combination vehicle may not exceed a 
    total maximum gross weight of 143,000 pounds. An eight-axle combination 
    vehicle may not exceed a total maximum gross weight of 138,400 pounds. 
    The maximum gross weight that may be carried upon any combination of 
    units is limited by the maximum gross weight that can be carried upon 
    the axles as follows. For a nine-axle combination: Drive axles--36,000 
    pounds, axles four/five--36,000 pounds, axles six/seven--27,000 pounds, 
    and axles eight/nine--36,000 pounds. A minimum 12-foot axle spacing 
    between the fifth and sixth axles is also required on the nine-axle 
    LCV. For an eight-axle combination: Drive axles--36,000 pounds, axles 
    four/five--36,000 pounds, sixth axle--22,400 pounds, and axles seven/
    eight--36,000 pounds. The eight-axle LCV has no minimum axle-spacing 
    requirements. For gross weights in excess of 138,400 pounds the 
    combination must include a tandem-axle dolly to meet the nine-axle 
    requirements. Maximum permissible gross weight for B-train combination 
    is 127,000 pounds.
        When the gross weight of the two trailers in a tandem combination 
    vary more than 20 percent, the heaviest of the two must be placed in 
    the lead position.
        For tandem trailer combinations in which neither trailing unit 
    exceeds 28.5 feet in length the following maximum allowable weights 
    apply: for a single axle--28,000 pounds (except that steering axles may 
    not exceed 22,400 pounds), for a tandem axle--42,500 pounds, for a tri-
    axle--52,500 pounds. The gross weight may not exceed 100,000 pounds or 
    the manufacturers gross weight rating, whichever is lower.
        DRIVER: For operation on highways under the jurisdiction of the New 
    York State Thruway Authority (NYSTA), except for the full length of I-
    84 and that portion of I-287 from Thruway exit 8 to I-95, the driver 
    must have a commercial driver's license with the appropriate 
    endorsement, and hold a Tandem Trailer Driver's Permit issued by the 
    NYSTA. In order to obtain an NYSTA driver's permit, an applicant must 
    (1) hold a valid commercial driver's license with multiple-trailer 
    endorsement; (2) be over 26 years old, in good health, and have at 
    least 5 years of provable experience driving tractor-trailer 
    combinations; and (3) meet all other application requirements with 
    regard to driving history established by the NYSTA. Qualified drivers 
    receive a Tandem Trailer Driver's Permit for Tandem Vehicle Operation 
    which is valid only for the operation of the certified equipment owned 
    by the company to which the permit is issued.
        For operation on highways under the jurisdiction of the New York 
    State DOT, cities not wholly included in one county, the full length of 
    I-84 and that portion of I-287 from Thruway exit 8 to I-95, the driver 
    must have a commercial driver's license with the appropriate 
    endorsement.
        VEHICLE: All vehicles must meet the requirements of applicable 
    Federal and State statutes, rules, and regulations. Vehicles operating 
    on highways under the jurisdiction of the NYSTA, except for the full 
    length of I-84 and that portion of I-287 from Thruway exit 8 to I-95, 
    must also meet the following additional requirements. The tractor 
    manufacturer and the permittee shall certify to the NYSTA prior to the 
    approval of the tractor that it is capable of hauling the maximum 
    permissible gross load at a speed of not less than 20 miles per hour on 
    all portions of the thruway system.
        The brakes on any vehicle, dolly converter, or combination of 
    vehicles shall comply with 49 CFR part 393 and, in addition, any 
    vehicle or dolly converter shall meet the provisions of the New York 
    State Traffic Law.
        Tandem trailer operations shall be equipped, at a minimum, with 
    emergency equipment as required by 49 CFR part 393, subpart H, as 
    amended, tire chains from October 15 to May 1 of each year, a fire 
    extinguisher with an aggregate rating of 20BC, and each trailer with 
    specific lamps and reflectors.
        All tractors certified by the NYSTA for use with tandem trailers 
    will be assigned an identification number by the NYSTA which must be 
    placed on the vehicle. The number must be at least 3 inches in height 
    and visible to a person standing at ground level opposite the driver's 
    position in the cab.
        Axle Type. Tractors to be used for hauling 110,000 pounds or more 
    shall be equipped with tandem rear axles, both with driving power. 
    Tractors to be used for hauling 110,000 pounds or less may have a 
    single drive axle. Tandem combinations using single wheel tires 
    commonly referred to as ``Super Singles'' are required to use triple-
    axle tractors, dual-axle trailers, and dual-axle dollies.
        Dollies. Every converter dolly certified on and after June 1, 1968, 
    used to convert a semitrailer to a full trailer may have either single 
    or tandem axles at the option of the permittee. Single-axle dollies may 
    not utilize low profile tires. Combination vehicles with a gross weight 
    in excess of 138,400 pounds must have a tandem-axle dolly to meet the 
    nine-axle requirement. If the distance between two semitrailers is 10 
    feet or more, the dolly shall be equipped with a device or the trailers 
    connected along the sides with suitable material to indicate they are 
    in effect one unit. The devices or connection shall be approved by the 
    NYSTA prior to use on a tandem trailer combination. The NYSTA tandem-
    trailer provisions require that converter dollies shall be coupled with 
    one or more safety chains or cables to the frame or an extension of the 
    frame of the motor vehicle by which it is towed. Each dolly converter 
    must also be equipped with mud flaps. Tandem combinations using a 
    sliding fifth wheel attached to the lead trailer, known as a ``B-
    Train'' combination, will require a separate Thruway Engineer Service 
    approval prior to the initial tandem run. Special provisions regarding 
    B-Trains will be reviewed at the time of the application or request for 
    use on the Thruway.
        PERMIT: For operation on highways under the jurisdiction of the New 
    York State DOT, cities not wholly included in one county, or the 
    following highway sections under NYSTA jurisdiction; the full length of 
    I-84 and that portion of I-287 from Thruway exit 8 to I-95, a permit to 
    exceed the weight limits set forth in section 385(15) of the New York 
    State Vehicle and Traffic Law must be obtained from the State DOT, city 
    involved, or the NYSTA. A fee is charged for the permit.
        For operation on highways under the jurisdiction of the NYSTA, 
    except for the full length of I-84 and that portion of I-287 from 
    Thruway exit 8 to I-95, companies must file an application for a Tandem 
    Trailer Permit with the NYSTA. Permits are issued to such companies 
    upon meeting qualifications, including insurance, for tandem 
    combinations over 65 feet in length. No permit fee is charged; however, 
    Thruway tolls are charged for each use of the Thruway, and the 
    equipment must be certified by the NYSTA annually. The annual re-
    certification of equipment is handled by: New York State Thruway 
    Authority, Manager of Traffic Safety Services, P.O. Box 189, Albany, 
    New York 12201-0189

    STATE: NORTH DAKOTA
    
    COMBINATION: Truck tractor and 2 trailing units--LCV
    LENGTH OF THE CARGO-CARRYING UNITS: 103 feet
    MAXIMUM ALLOWABLE GROSS WEIGHT: 105,500 pounds
    OPERATIONAL CONDITIONS:
        WEIGHT: The Gross Vehicle Weight (GVW) of any vehicle or 
    combination of vehicles is determined by the Federal Bridge Formula, 
    including the exception for two sets of tandems spaced 36 feet apart.
        No single axle shall carry a gross weight in excess of 20,000 
    pounds. Axles spaced 40 inches or less apart are considered one axle. 
    Axles spaced 8 feet or more apart are considered as individual axles. 
    The gross weight of two individual axles may be restricted by the 
    weight formula. Spacing between axles shall be measured from axle 
    center to axle center.
        Axles spaced over 40 inches but less than 8 feet apart shall not 
    carry a gross weight in excess of 17,000 pounds per axle. The gross 
    weight of three or more axles in a grouping is determined by the 
    measurement between the extreme axle centers. During the spring breakup 
    season or on otherwise posted highways, reductions in the above axle 
    weights may be specified.
        The weight in pounds on any one wheel shall not exceed one-half the 
    allowable axle weight. Dual tires are considered one wheel.
        The weight per inch of tire width shall not exceed 550 pounds. The 
    width of tire shall be the manufacturer's rating.
        DRIVER: The driver must have a commercial driver's license with the 
    appropriate endorsement.
        VEHICLE: The cargo length of a two trailing unit combination may 
    not exceed 100 feet (when the power unit is a truck tractor) or 103 
    feet (when the power unit is a truck) when traveling on the NN or local 
    highways designated by local authorities.
        All hitches must be of a load-bearing capacity capable of bearing 
    the weight of the towed vehicles. The towing vehicle must have a hitch 
    commonly described as a fifth wheel or gooseneck design, or one that is 
    attached to the frame.
        The hitch on the rear of the vehicle connected to the towing 
    vehicle must be attached to the frame of the towed vehicle. All 
    hitches, other than a fifth wheel or gooseneck, must be of a ball and 
    socket type with a locking device or a pintle hook.
        The drawn vehicles shall be equipped with brakes and safety chains 
    adequate to control the movement of, and to stop and hold, such 
    vehicles. When the drawn vehicle is of a fifth wheel or gooseneck 
    design, safety chains are not required.
        In any truck or truck tractor and two trailer combination, the 
    lighter trailer must always be operated as the rear trailer, except 
    when the gross weight differential with the other trailer does not 
    exceed 5,000 pounds.
        The power unit shall have adequate power and traction to maintain a 
    minimum speed of 15 miles per hour on all grades.
        PERMIT: No permits are required for GVW of 80,000 pounds or less. 
    Single-trip permits are required for GVW exceeding 80,000 pounds. 
    Weather restrictions (37-06-04-06, NDAC), weight distribution on 
    trailers (37-06-04, NDAC), and signing requirements (37-06-04-05, NDAC) 
    are applicable.
        Movements of LCV's are prohibited when:
        1. Road surfaces, due to ice, snow, slush, or frost present a 
    slippery condition which may be hazardous to the operation of the unit 
    or to other highway users;
        2. Wind or other conditions may cause the unit or any part thereof 
    to swerve, whip, sway, or fail to follow substantially in the path of 
    the towing vehicle; or
        3. Visibility is reduced due to snow, ice, sleet, fog, mist, rain, 
    dust, or smoke.
        The North Dakota Highway Patrol may restrict or prohibit operations 
    during periods when in its judgment traffic, weather, or other safety 
    conditions make travel unsafe.
        The last trailer in any combination must have a ``LONG LOAD'' sign 
    mounted on the rear. It must be a minimum of 12 inches in height and 60 
    inches in length. The lettering must be 8 inches in height with 1-inch 
    brush strokes. The letters must be black on a yellow background.
        Legal width--8 feet 6 inches on all highways.
        Legal height--13 feet 6 inches.
        ACCESS: Access for vehicles with cargo-carrying length of 68 feet 
    or more is 10 miles off the NN. Vehicles with a cargo-carrying length 
    less than 68 feet may travel on all highways in North Dakota.
        ROUTES: All NN routes.

    COMBINATION: Truck tractor and 2 trailing units--LCV
    LENGTH OF THE CARGO-CARRYING UNITS: 102 feet
    MAXIMUM ALLOWABLE GROSS WEIGHT: 127,400 pounds
        OPERATIONAL CONDITIONS: Long double combination vehicles are only 
    allowed on that portion of Ohio's Interstate System which is under the 
    jurisdiction of the Ohio Turnpike Commission (OTC). These same vehicles 
    are not allowed on any portion of the Interstate System under the 
    jurisdiction of the Ohio DOT.
        WEIGHT: The OTC has established the following provisions for 
    operation:
        Maximum Weight: Single axle = 21,000 pounds; tandem axle spaced 4 
    feet or less apart = 24,000 pounds; tandem axle spaced more than 4 feet 
    but less than 8 feet apart = 34,000 pounds; gross weight for doubles 90 
    feet or less in length = 90,000 pounds; gross weight for doubles over 
    90 feet but less than 112 feet in length = 127,400 pounds.
        DRIVER: The driver must have a commercial driver's license with the 
    appropriate endorsement, be over 26 years of age, in good health, and 
    shall have not less than 5 years of experience driving tractor-trailer 
    or tractor-short double trailer motor vehicles. Such driving experience 
    shall include experience throughout the four seasons. Drivers must 
    comply with the applicable current requirements of the Federal Motor 
    Carrier Safety Regulations, Federal Hazardous Materials Regulations, 
    and the Economic and Safety regulations of the Ohio Public Utility 
    Commission.
        VEHICLE: Vehicles being operated under permit at night must be 
    equipped with all lights and reflectors required by the Ohio Public 
    Utilities Commission and the Federal Motor Carrier Safety Regulations, 
    except that the trailer shall be equipped with two red tail lights and 
    two red or amber stop lights mounted with one set on each side. Trailer 
    and semitrailer length for doubles cannot exceed 48 feet, and mixed 
    trailer length combinations are not allowed for combination vehicles 
    over 90 feet in length. Combined cargo-carrying length, including the 
    trailer hitch, cannot be less than 80 feet or more than 102 feet. The 
    number of axles on a double shall be a minimum of five and a maximum of 
    nine. A tractor used in the operation of a double shall be capable of 
    hauling the maximum weight at a speed of not less than 40 miles per 
    hour on all portions of the Turnpike.
        PERMIT: A special permit is required if the vehicle is over 102 
    inches wide, 14 feet high, or 65 feet in length including overhang. 
    Tractor-semitrailer-semitrailer combinations require a permit if over 
    75 feet in length, excluding an allowed 3-foot front overhang and a 4-
    foot rear overhang. For vehicles over 120 inches wide, 14 feet high, or 
    80 feet long or if any unit of the combination vehicle is over 60 feet 
    in length, travel is restricted to daylight hours Monday through noon 
    Saturday, except holidays and the day before and after holidays. 
    Operators are restricted to daylight driving if the load overhang is 
    more than 4 feet. A ``Long Double Trailer Permit'' issued by the OTC is 
    required for operation of doubles in excess of 90 feet in length. 
    Towing units and coupling devices shall have sufficient structural 
    strength to ensure safe operation. Vehicles and coupling devices shall 
    be so designed, constructed, and installed in a double as to ensure 
    that any towed vehicles when traveling on a level, smooth paved surface 
    will follow in the path of the towing vehicle without shifting or 
    swerving more than 3 inches to either side of the path of the towing 
    vehicle when the latter is moving in a straight line. Vehicle coupling 
    devices and brakes shall meet the requirements of the Ohio Public 
    Utilities Commission and Federal Motor Carrier Safety Regulations. The 
    distance between the rearmost axle of a semitrailer and the front axle 
    of the next semitrailer in a coupled double unit shall not exceed 12 
    feet 6 inches. In no event shall the distance between the semitrailers 
    coupled in a double exceed 9 feet. Double and triple trailer 
    combinations must be equipped with adequate, properly maintained spray-
    suppressant mud flaps on all axles except the steering axle. In the 
    event that the gross weights of the trailers vary by more than 20 
    percent, they shall be coupled according to their gross weights with 
    the heavier trailer forward. A minimum distance of 500 feet shall be 
    maintained between double units and/or triple units except when 
    overtaking and passing another vehicle. A double shall remain in the 
    right-hand, outside lane except when passing or when emergency or work-
    zone conditions exist. When, in the opinion of the OTC, the weather 
    conditions are such that operation of a double is inadvisable, the OTC 
    will notify the permittee that travel is prohibited for a certain 
    period of time.
        Class A and B explosives; Class A poisons; and Class 1, 2, and 3 
    radioactive material cannot be transported in double trailer 
    combinations. Other hazardous materials may be transported in one 
    trailer of a double. The hazardous materials should be placed in the 
    front trailer unless doing so will result in the second trailer 
    weighing more than the first trailer.
        ACCESS: Tandem trailer units shall not leave the Turnpike right-of-
    way and shall be assembled and disassembled only in designated areas 
    located at Exits 4, 7, 10, 11, 13, 14, and 16.

    feet in length. The minimum number of axles on the triple shall be 
    seven and the maximum is nine.
        PERMIT: A triple trailer permit to operate on the Turnpike is 
    required for triple trailer combinations in excess of 90 feet in 
    length. There is an annual fee for the permit. Class A and B 
    explosives; Class A poisons; and Class 1, 2, and 3 radioactive material 
    cannot be transported in triple trailer combinations. Other hazardous 
    materials may be transported in two trailers of a triple. The hazardous 
    materials should be placed in the front two trailers unless doing so 
    will result in the third trailer weighing more than either one of the 
    lead trailers.
        ACCESS: With two exceptions, triple trailer units shall not leave 
    the Turnpike right-of-way and shall be assembled and disassembled only 
    in designated areas located at Exits 4, 7, 10, 11, 13, 14, and 16. The 
    first exception is that triple trailer combinations are allowed on 
    State Route 21 from I-80 Exit 11 (Ohio Turnpike) to a terminal located 
    approximately 500 feet to the north in the town of Richfield. The 
    second exception is for a segment of State Route 7 from Ohio Turnpike 
    Exit 16 to 1 mile south.

        DRIVER: All drivers must have a commercial driver's license with 
    the appropriate endorsement and must meet the requirements of the 
    Federal Motor Carrier Safety Regulations (49 CFR parts 390-397). State 
    requirements more stringent and not in conflict with Federal 
    requirements take precedence.
        VEHICLE: All vehicles must meet the requirements of applicable 
    Federal and State statutes, rules, and regulations. Vehicle and load 
    shall not exceed 102 inches in width on the Interstate System and four-
    lane divided highways. Maximum semitrailer length is 59.5 feet.
        Multiple trailer combinations must be stable at all times during 
    braking and normal operation. A multiple trailer combination when 
    traveling on a level, smooth paved surface must follow in the path of 
    the towing vehicle without shifting or swerving more than 3 inches to 
    either side when the towing vehicle is moving in a straight line. 
    Heavier trailers are to be placed to the front in multiple trailer 
    combinations.
        PERMIT: An annual special authorization permit is required for 
    tandem trailer vehicles operating on the Interstate System having a 
    gross weight of more than 80,000 pounds. A fee is charged for the 
    special authorization permit.
        ACCESS: Access is allowed from legally available routes (listed 
    below) to service facilities and terminals within a 5-mile radius.

    STATE: OKLAHOMA
    
    COMBINATION: Truck tractor and 3 trailing units--LCV
    LENGTH OF THE CARGO-CARRYING UNITS: 95 feet
    MAXIMUM ALLOWABLE GROSS WEIGHT: 90,000 pounds
    OPERATIONAL CONDITIONS:
        WEIGHT and ACCESS: Same as the OK-TT2 combination.
        DRIVER: Same as the OK-TT2 combination except that in addition, a 
    driver of a three trailing unit combination must have had at least 2 
    years of experience driving tractor-trailer combinations.
        VEHICLE: All vehicles must meet the requirements of applicable 
    Federal and State statutes, rules, and regulations. Vehicle and load 
    shall not exceed 102 inches in width on the Interstate System and other 
    four-lane divided highways. Maximum unit length of triple trailers is 
    29 feet. Truck tractors pulling triple trailers must have sufficient 
    horsepower to maintain a minimum speed of 40 miles per hour on the 
    level and 20 miles per hour on grades under normal operation 
    conditions. Heavy-duty fifth wheels, pick-up plates equal in strength 
    to the fifth wheel, solid kingpins, no-slack hitch connections, mud 
    flaps and splash guards, and full-width axles are required on triple 
    trailer combinations. All braking systems must comply with State and 
    Federal requirements.
        Multiple trailer combinations must be stable at all times during 
    braking and normal operation. A multiple trailer combination when 
    traveling on a level, smooth paved surface must follow in the path of 
    the towing vehicle without shifting or swerving more than 3 inches to 
    either side when the towing vehicle is moving in a straight line. 
    Heavier trailers are to be placed to the front in multiple trailer 
    combinations.
        PERMIT: An annual special authorization permit is required for 
    triple trailer combination vehicles operating on the Interstate System 
    having a gross weight of more than 80,000 pounds. A special vehicle 
    combination permit is required for the operation of triple trailers on 
    the Interstate System and on other four-lane divided primary highways. 
    The permit holder must certify that the driver of a triple trailer 
    combination is qualified. Operators of triples must maintain a 500-foot 
    following distance and must drive in the right lane except when passing 
    or in an emergency.
        Speed shall be reduced and extreme caution exercised when operating 
    triples under hazardous conditions such as those caused by snow, wind, 
    ice, sleet, fog, mist, rain, dust, or smoke. When conditions become 
    sufficiently dangerous as determined by the company or driver, 
    operations shall be discontinued and shall not resume until the vehicle 
    can be safely operated. The State may restrict or prohibit operations 
    during periods when, in the State's judgment, traffic, weather, or 
    other safety conditions make such operations unsafe or inadvisable.
        Class A and B explosives; Class A poisons; and Class 1, 2, and 3 
    radioactive material or any other material deemed to be unduly 
    hazardous by the U.S. DOT cannot be transported in triple trailer 
    combinations.

        Distance measured to nearest foot; when exactly one-half foot, take 
    next larger number.
        DRIVER: The driver must have a commercial driver's license with the 
    appropriate endorsement.
        VEHICLE: For a combination which includes a truck tractor and two 
    trailing units, the lead trailing unit (semitrailer) may be up to 40 
    feet long. The second trailing unit may be up to 35 feet long. However, 
    the primary control is the total cargo-carrying distance which has a 
    maximum length of 68 feet. Any towed vehicles in a combination must be 
    equipped with safety chains or cables to prevent the towbar from 
    dropping to the ground in the event the coupling fails. The chains or 
    cables must have sufficient strength to control the towed vehicle in 
    the event the coupling device fails and must be attached with no more 
    slack than necessary to permit proper turning. However, this 
    requirement does not apply to a fifth-wheel coupling if the upper and 
    lower halves of the fifth wheel must be manually released before they 
    can be separated.
        PERMIT: A permit is required for operation if the gross combination 
    weight exceeds 80,000 pounds. A fee is charged. Permitted movements 
    must have the lighter trailing unit placed to the rear, and use splash 
    and spray devices when operating in rainy weather. Movement is not 
    allowed when road surfaces are hazardous due to ice or snow, or when 
    other atmospheric conditions make travel unsafe.
        ACCESS: As allowed by the Oregon DOT.
        ROUTES: All NN routes.
        LEGAL CITATIONS: ORS 810.010, ORS 810.030 through 810.060, and ORS

    COMBINATION: Truck tractor and 3 trailing units--LCV
    LENGTH OF THE CARGO-CARRYING UNITS: 96 feet
    MAXIMUM ALLOWABLE GROSS WEIGHT: 105,500 pounds
    OPERATIONAL CONDITIONS:
        WEIGHT, DRIVER, PERMIT, and ACCESS: Same as the OR-TT2 combination.
        VEHICLE: Trailing units must be of equal length. The overall length 
    of the combination is limited to 105 feet. Any towed vehicles in a 
    combination must be equipped with safety chains or cables to prevent 
    the towbar from dropping to the ground in the event the coupling fails. 
    The chains or cables must have sufficient strength to control the towed 
    vehicle in the event the coupling device fails and must be attached 
    with no more slack than necessary to permit proper turning. However, 
    this requirement does not apply to a fifth-wheel coupling if the upper 
    and lower halves of the fifth wheel must be manually released before 
    they can be separated.
        ROUTES: The following NN routes are also open to truck tractor and 
    three trailing unit combinations.

    STATE: SOUTH DAKOTA
    
    COMBINATION: Truck tractor and 2 trailing units--LCV
    LENGTH OF CARGO-CARRYING UNITS: 100 feet
    MAXIMUM ALLOWABLE GROSS WEIGHT: 129,000 pounds
    OPERATIONAL CONDITIONS:
        WEIGHT: For all combinations, the maximum gross weight on two or 
    more consecutive axles is limited by the Federal Bridge Formula but 
    cannot exceed 129,000 pounds. The weight on single axles or tandem 
    axles spaced 40 inches or less apart may not exceed 20,000 pounds. 
    Tandem axles spaced more than 40 inches but 96 inches or less may not 
    exceed 34,000 pounds. Two consecutive sets of tandem axles may carry a 
    gross load of 34,000 pounds each, provided the overall distance between 
    the first and last axles of the tandems is 36 feet or more. The weight 
    on the steering axle may not exceed 600 pounds per inch of tire width.
        For combinations with a cargo-carrying length greater than 81.5 
    feet the following additional regulations also apply. The weight on all 
    axles (other than the steering axle) may not exceed 500 pounds per inch 
    of tire width. Lift axles and belly axles are not considered load-
    carrying axles and will not count when determining allowable vehicle 
    weight.
        DRIVER: The driver must have a commercial driver's license with the 
    appropriate endorsement.
        VEHICLE: For all combinations, a semitrailer or trailer may neither 
    be longer than nor weigh 3,000 pounds more than the trailer located 
    immediately in front of it. Towbars longer than 19 feet must be flagged 
    during daylight hours and lighted at night.
        For combinations with a cargo-carrying length of 81.5 feet or less, 
    neither trailer may exceed 45 feet, including load overhang. Vehicles 
    may be 12 feet wide when hauling baled feed during daylight hours.
        For combinations with a cargo-carrying length over 81.5 feet long, 
    neither trailer may exceed 48 feet, including load overhang. Loading 
    the rear of the trailer heavier than the front is not allowed. All 
    axles except the steering axle require dual tires. Axles spaced 8 feet 
    or less apart must weigh within 500 pounds of each other. The trailer 
    hitch offset may not exceed 6 feet. The maximum effective rear trailer 
    overhang may not exceed 35 percent of the trailer's wheelbase. The 
    power unit must have sufficient power to maintain 40 miles per hour. A 
    ``LONG LOAD'' sign measuring 18 inches high by 7 feet long with black 
    on yellow lettering 10 inches high is required on the rear. Offtracking 
    is limited to 8.75 feet for a turning radius of 161 feet.
    
        Offtracking Formula = 61-(161\2\-L1\2\-- 
    L2\2\+L3\2\-L4\2\-L5\2\+L6\2\-L7\2\-L8
    \2\) \1\/\2\.
    
        Note: L1 through L8 are measurements between points of 
    articulation or vehicle pivot points. Squared dimensions to stinger 
    steer points of articulation are negative. For two trailing unit 
    combinations where at least one trailer is 45 feet long or longer, 
    all the dimensions used to calculate offtracking must be written in 
    the ``Permit Restriction'' area of the permit along with the 
    offtracking value derived from the calculation.
    
        PERMIT: For combinations with a cargo-carrying length of 81.5 feet 
    or less, a single-trip permit is required for movement on the 
    Interstate System if the gross vehicle weight exceeds 80,000 pounds. An 
    annual or single-trip permit is required for hauling baled feed over 
    102 inches wide.
        For combinations with a cargo-carrying length greater than 81.5 
    feet, a single-trip permit is required for all movements. Operations 
    must be discontinued when roads are slippery due to moisture, 
    visibility must be good, and wind conditions must not cause trailer 
    whip or sway.
        For all combinations, a fee is charged for any permit.
        ACCESS: For combinations with a cargo-carrying length of 81.5 feet 
    or less, access is Statewide off the NN unless restricted by the South 
    Dakota DOT.
        For combinations with a cargo-carrying length greater than 81.5 
    feet, access to operating routes must be approved by the South Dakota 
    DOT.
        ROUTES: Combinations with a cargo-carrying length of 81.5 feet or 
    less may use all NN routes. Combinations with a cargo-carrying length 
    over 81.5 feet, are restricted to the Interstate System and:

    COMBINATION: Truck tractor and 2 trailing units--LCV
    LENGTH OF THE CARGO-CARRYING UNITS: 95 feet
    MAXIMUM ALLOWABLE GROSS WEIGHT: 129,000 pounds
    OPERATIONAL CONDITIONS:
        WEIGHT: Weight limits are as follows:
    Single axle: 20,000 pounds
    Tandem axle: 34,000 pounds
    Gross weight: 129,000 pounds
    Vehicles must comply with the Federal Bridge Formula
        Tire loading on vehicles requiring an overweight or oversize permit 
    shall not exceed 500 pounds per inch of tire width for tires 11 inches 
    wide and greater, and 450 pounds per inch of tire width for tires less 
    than 11 inches wide as designated by the tire manufacturer on the side 
    wall of the tire. Tire loading on vehicles not requiring an overweight 
    or oversize permit shall not exceed 600 pounds per inch of tire width 
    as designated by the tire manufacturer on the sidewall.
        DRIVER: The driver must have a commercial driver's license with the 
    appropriate endorsement. Carriers must certify that their drivers have 
    a safe driving record and have passed a road test administered by a 
    qualified safety supervisor.
        VEHICLE: While in transit, no trailer shall be positioned ahead of 
    another trailer which carries an appreciably heavier load. An empty 
    trailer shall not precede a loaded trailer. Vehicles shall be powered 
    to operate on level terrain at speeds compatible with other traffic. 
    They must be able to maintain a minimum speed of 20 miles per hour 
    under normal operating conditions on any grade of 5 percent or less 
    over which the combination is operated and be able to resume a speed of 
    20 miles per hour after stopping on any such grade, except in extreme 
    weather conditions.
        Oversize signs are required on vehicles in excess of 75 feet in 
    length on two-lane highways.
        A heavy-duty fifth wheel is required. All fifth wheels must be 
    clean and lubricated with a light-duty grease prior to each trip. The 
    fifth wheel must be located in a position which provides adequate 
    stability. Pick-up plates must be of equal strength to the fifth wheel. 
    The kingpin must be of a solid type and permanently fastened. Screw-out 
    or folding-type kingpins are prohibited.
        All hitch connections must be of a no-slack type, preferably a 
    power-actuated ram. Air-actuated hitches which are isolated from the 
    primary air transmission system are recommended.
        The drawbar length should be the practical minimum consistent with 
    the clearances required between trailers for turning and backing 
    maneuvers.
        Axles must be those designed for the width of the body.
        All braking systems must comply with State and Federal 
    requirements. In addition, fast air transmission and release valves 
    must be provided on all semitrailer and converter-dolly axles. A brake 
    force limiting valve, sometimes called a ``slippery road'' valve, may 
    be provided on the steering axle. Anti-sail type mud flaps are 
    recommended.
        The use of single tires on any combination vehicle requiring an 
    overweight or oversize permit shall not be allowed on single axles. A 
    single axle is defined as one having more than 8 feet between it and 
    the nearest axle or group of axles on the vehicle.
        When traveling on a level, smooth paved surface, the trailing units 
    must follow in the path of the towing vehicle without shifting or 
    swerving more than 3 inches to either side when the towing vehicle is 
    moving in a straight line. Each combination shall maintain a minimum 
    distance of 500 feet from another commercial vehicle traveling in the 
    same direction on the same highway. Loads shall be securely fastened to 
    the transporter with material and devices of sufficient strength to 
    prevent the load from becoming loose, detached, dangerously displaced, 
    or in any manner a hazard to other highway users. The components of the 
    load shall be reinforced or bound securely in advance of travel to 
    prevent debris from being blown off the unit and endangering the safety 
    of the traveling public. Any debris from the special permit vehicle 
    deposited on the highway shall be removed by the permittee.
        Bodily injury and property damage insurance is required before a 
    special Transportation Permit will be issued.
        In the event any claim arises against the State of Utah, Utah 
    Department of Transportation, Utah Highway Patrol, or their employees 
    from the operation granted under the permit, the permittee shall agree 
    to indemnify and hold harmless each of them from such claim.
        PERMIT: Permits must be purchased. The Utah DOT Motor Carrier 
    Safety Division will, on submission of an LCV permit request, assign an

    Carrier Safety Regulations (49 CFR parts 387-399), the Federal 
    Hazardous Materials Regulations (49 CFR parts 171-178), and a 
    ``Satisfactory'' safety rating. The request must show a travel plan for 
    the operation of the vehicles. Permits are subject to Highway Patrol 
    supervision and permitted vehicles may be subject to temporary delays 
    or removed from the highways when necessary during hazardous road, 
    weather, or traffic conditions. The permit will be cancelled without 
    refund if violated. Expiration dates cannot be extended except for 
    reasons beyond the control of the permittee, including adverse weather. 
    Permits are void if defaced, modified, or obliterated. Lost or 
    destroyed permits cannot be duplicated and are not transferable.
