    SUMMARY: NHTSA sets forth alternative proposals for changing the 
    Federal Motor Vehicle Safety Standard on windshield defrosting and 
    defogging systems. The proposals range from applying performance 
    requirements to the systems in light trucks and multipurpose passenger 
    vehicles to rescinding the Standard. This action is part of NHTSA's 
    efforts to implement the President's Regulatory Reinvention Initiative.

    SUPPLEMENTARY INFORMATION:
    
    President's Regulatory Reinvention Initiative
    
        Pursuant to the March 4, 1995, directive ``Regulatory Reinvention 
    Initiative'' from the President to the heads of departments and 
    agencies, NHTSA undertook a review of its regulations. During the 
    course of this review, NHTSA identified regulations that it could 
    propose to eliminate as unnecessary or to amend to improve their 
    comprehensibility, application, or appropriateness. Among these 
    regulations is Federal Motor Vehicle Safety Standard No. 103, 
    Windshield defrosting and defogging systems 49 CFR 571.103). After 
    reviewing below the background of the standard, NHTSA explains why it 
    is proposing changes to Standard No. 103.
    
    Background of Standard No. 103
    
        Standard No. 103 was issued in 1967 (32 FR 2408) as one of the 
    initial Federal Motor Vehicle Safety Standards (FMVSSs). The standard, 
    applicable to passenger cars, multipurpose passenger vehicles (MPVs), 
    trucks, and buses, specifies in S4.1 that each of these vehicles shall 
    have a windshield defrosting and defogging system.
        Standard No. 103 specifies performance requirements for the 
    windshield defrosting and defogging systems in passenger cars, but not 
    for the systems in the other types of vehicles covered by the Standard. 
    S4.2 of Standard No. 103 specifies that each passenger car windshield 
    defrosting and defogging system shall meet specified provisions of SAE 
    Recommended Practice J902 (SAE J902), ``Passenger Car Windshield 
    Defrosting Systems,'' August 1964.
        SAE J902 establishes uniform test procedures and minimum 
    performance requirements for the ``critical area'' of the windshield 
    and for the ``entire windshield.'' SAE J902 prescribes a laboratory 
    evaluation of defroster systems during which a known quantity of water 
    is sprayed on the windshield, forming an ice coating, to provide 
    uniform and repeatable test results. However, while Standard No. 103 
    incorporates the test procedures and performance requirements of SAE 
    J902, it does not incorporate the SAE J902's definition of ``critical 
    area'' and ``entire windshield.'' Instead, Standard No. 103 substitutes 
    areas of the windshield determined in accordance with Standard No. 104, 
    ``Windshield Wiping and Washing Systems.'' It substitutes Area C from 
    Standard No. 104 for the ``critical area'' and Area A for the ``entire 
    windshield.''
        Vehicles manufactured for sale in the ``noncontinental United 
    States,'' which have tropical climates and where snow and icing 
    conditions are thus virtually unknown, have the option of either 
    meeting S4.1 of Standard No. 103 (i.e., installing a windshield 
    defrosting and defogging system) or installing a windshield defogging 
    system which operates either by applying heat to the windshield or by 
    dehumidifying the air inside the passenger compartment of the vehicle. 
    Since air conditioners dehumidify the air in addition to cooling it, 
    all vehicles with air conditioners have defogging capability,
    
    [[Page 15450]]
    whether or not they have a separate defrosting and defogging system.
        Standard No. 103 has had a fairly uneventful history. Very few 
    changes have been made to it since its promulgation, other than an 
    amendment in 1994 to accommodate electric- powered vehicles.
    
    NHTSA's Review of Standard No. 103 and Proposals for Change
    
        Based on its review of Standard No. 103 under the President's 
    Regulatory Reform Initiative, NHTSA offers three proposals for changes 
    to the Standard and seeks public comment on each proposal. The 
    proposals are: (1) Rescinding the Standard; (2) upgrading the light 
    truck and MPV requirements to make them equivalent to the passenger car 
    requirements; and (3) eliminating duplicative language by combining 
    Standard Nos. 103 and 104 into a single safety standard and retitling 
    it Windshield clearance systems, since Standard No. 103 presently 
    references provisions in Standard No. 104.
        Due to the relative simplicity of the proposals, the agency is not 
    setting forth precise regulatory language for implementing the 
    proposals.
        In addition to seeking comments on each of the three proposals, the 
    agency also seeks comment on the option of making no changes to the 
    Standard.
    
    1. Proposal One--Rescind Standard No. 103
    
        NHTSA's first alternative proposal is to rescind Standard No. 103. 
    To adopt this proposal, NHTSA would conclude that even if Standard No. 
    103 should be rescinded, manufacturers would continue to provide means 
    to defrost and defog windshields. It is widely recognized that, in 
    icing or highly humid conditions, a motor vehicle must have some means 
    for keeping the windshield clear so that the driver can view the road 
    ahead. More important, the fact that light trucks and MPVs provide 
    defrosting and defogging performance comparable to that in passenger 
    cars, despite the absence of performance requirements for light trucks 
    and MPVs, could be said to indicate that passenger cars would continue 
    to provide that level of performance in the absence of performance 
    requirements.
        Market forces (in the form of customer demand) would be highly 
    likely to ensure that most vehicle manufacturers continue to provide 
    windshield defrosting and defogging systems in motor vehicles. Customer 
    magazines and consumers themselves would be likely to react negatively 
    to vehicles that do not have adequate windshield defrosting and 
    defogging systems. It should also be noted that nearly 75 percent of 
    all cars have a rear defroster, although this is not required by 
    Standard No. 103, indicating the working of market forces in this area.
        NHTSA notes that if Standard No. 103 were rescinded, some States 
    might adopt regulations requiring windshield defrosting and defogging 
    systems or even regulate their performance. Were the States to adopt 
    such regulations, there would not be any express preemption under 49 
    U.S.C. section 30103(b), Preemption, of State requirements dissimilar 
    to those currently in Standard No. 103. It also does not appear likely 
    that a court would find any implied Federal preemption of State 
    requirements, regardless of whether they are similar or dissimilar to 
    those in the Standard. A State regulation addressing the same subject 
    as a rescinded Federal regulation would be impliedly preempted only if 
    the State regulation conflicted with or otherwise frustrated achieving 
    the purposes of the Federal statute. Even if the agency were to 
    conclude that no regulation, Federal or State, of windshield defrosting 
    and defogging is necessary, it is not readily apparent how State 
    regulations, even ones differing from those of another State, on this 
    subject would conflict with Federal law or have a deleterious effect on 
    motor vehicle safety.
    
    2. Proposal Two--Upgrading the MPV and Light Truck Requirements to Make 
    Them Equivalent to the Passenger Car Requirements
    
        In the last decade, sales of light trucks and multipurpose 
    passenger vehicles (MPV) have increased substantially. In addition, 
    these vehicles have been increasingly used to transport passengers. As 
    a result, the numbers of deaths and injuries associated with those 
    vehicles have substantially increased.
        In response, NHTSA has amended some FMVSSs to ensure that the 
    public is afforded the same level of protection whether they ride in a 
    passenger car, light truck, or MPV. For example, by model year 1998, 
    the requirements for key FMVSSs such as Standard No. 208, Occupant 
    crash protection, and Standard No. 214, Side impact protection, will be 
    virtually identical for passenger cars, light trucks, and MPVs.
        In keeping with the trend to make FMVSS requirements uniform for 
    all three of these types of vehicles, under this proposal NHTSA would 
    specify performance requirements in Standard No. 103 for light trucks 
    and MPVs. As noted above, Standard No. 103 presently specifies no 
    requirements for light trucks and MPVs, other than that they have a 
    windshield defrosting and defogging system. This proposal would 
    establish minimum performance requirements for windshield defrosting 
    and defogging systems in light trucks and MPVs, including minimum 
    requirements regarding the portions of the windshield that must be 
    defrosted.
        As part of this proposal, the agency would extend passenger car 
    requirements for light trucks and MPVs, by extending S4.3's 
    Demonstration procedure to light trucks and MPVs. However, the minimum 
    windshield areas to be defrosted for light trucks and MPVs may differ 
    somewhat than those for passenger cars, since the windshields of these 
    various vehicle types differ, and the driver views different windshield 
    areas of each vehicle type while viewing the road ahead. Because of 
    potential differences in windshield viewing areas between the passenger 
    cars and other vehicle types, NHTSA seeks public comment on extending 
    S.4.3 to light trucks and MPVs.
        Any minimum requirements for windshield defrosting in light trucks 
    and MPVs would likely be based on the defrosted areas specified in SAE 
    Recommended Practice J382 (SAE J382) ``Windshield Defrosting Systems 
    Performance Requirements--Trucks, Buses, and Multipurpose Vehicle'' 
    (January 1971). Paragraph 3.1 of SAE J382 describes the portions of the 
    windshield that must be defrosted as follows: Area A (the largest area, 
    encompassing both the driver's and front passenger's view), Area B (an 
    area somewhat smaller than Area A) and Area C (the smallest area, in 
    front of the driver), described in Table 1 of SAE J382.
        NHTSA believes that if requirements concerning minimum windshield 
    defrosted areas were to be adopted for light trucks and MPVs, the 
    costs, if any, incurred by manufacturers would be slight. It appears 
    that virtually all light trucks and MPVs already meet SAE J382's 
    minimum defrosted area requirements, thus eliminating any possibility 
    of a need for design changes. Nevertheless, NHTSA seeks public comment 
    on cost increases. The potential for a slight cost increase comes from 
    the possibility that the manufacturers may not currently be doing as 
    much performance testing as they would if those requirements were 
    adopted.
        The agency does not propose to extend Standard No. 103 to heavier 
    trucks and buses, as it is not aware of an SAE or other standard for 
    windshield
    
    [[Page 15451]]
    
    defrosting and defogging systems on heavier trucks and buses. NHTSA 
    therefore requests information whether there are any industry (or 
    other) standards for windshield defrosting and defogging systems on 
    trucks and buses with a gross vehicle weight rating (GVWR) over 10,000 
    lbs. If such a standard exists, should NHTSA consider including it in 
    Standard No. 103, making Standard No. 103 apply to trucks and buses 
    with a GVWR over 10,000 lbs.?
        Consistent with the agency's intent to make Standard No. 103 as 
    uniform as possible for all vehicle types, if Proposal Two is adopted, 
    NHTSA also proposes to remove from Standard No. 103, S4.(b) that 
    applies to vehicles sold in the ``noncontinental United States.'' As 
    earlier described, S4.(b) provides that each passenger car, 
    multipurpose passenger vehicle, truck and bus manufactured for sale in 
    the noncontinental U.S. may, at the option of the manufacturer, have a 
    windshield defogging system which operates differently than the 
    generally applicable requirements. NHTSA requests public comment 
    whether S4.(b) should be removed.
    
    3. Proposal Three--Combining Standard Nos. 103 and 104
    
        NHTSA's third alternative proposal is to combine Standards Nos. 103 
    and 104 to make the standards easier to comprehend and apply. The two 
    standards are already substantially interconnected. Standard No. 103 
    references tables in Standard No. 104 to establish the angles used in 
    locating the defrosted areas. If the two standards were combined, the 
    single standard would be titled as a standard on windshield clearance 
    systems. In addition to seeking comments on this proposal, NHTSA would 
    entertain comments on combining this proposal with the preceding 
    proposal.
    
    Rulemaking Analyses and Notices
    
    1. Executive Order 12866 and DOT Regulatory Policies and Procedures
    
        This notice of proposed rulemaking was not reviewed under Executive 
    Order 12866 (Regulatory Planning and Review). NHTSA has analyzed the 
    impact of this rulemaking action and determined that it is not 
    ``significant'' within the meaning of the Department of 
    Transportation's regulatory policies and procedures.
        For Proposal One, NHTSA tentatively concludes that if that proposal 
    were adopted as a final rule, there may be slight cost savings to 
    industry, since manufacturers would no longer need to test vehicles for 
    compliance with Standard No. 103. The cost savings would be so minimal 
    that NHTSA is unable to quantify them. NHTSA tentatively believes 
    manufacturers likely would continue to provide essentially the same 
    level of defrosting and defogging capability as they currently provide.
        With respect to Proposal Two, it is NHTSA's tentative conclusion 
    that adoption of that proposal might result in only slightly increased 
    costs to industry, due to testing to new specifications. However, these 
    potential increased costs are so minimal that NHTSA is unable to 
    quantify them.
        If Proposal Three were adopted as a final rule, NHTSA anticipates 
    no changes in costs to industry, since no substantive changes to 
    Standard No. 103 would be made.
        Based on the foregoing, the agency concludes that the potential 
    impacts are so minimal as not to warrant preparation of a full 
    regulatory evaluation.
    
    2. Regulatory Flexibility Act
    
        NHTSA has also considered the impacts of this rule under the 
    Regulatory Flexibility Act. I hereby certify that this rule would not 
    have a significant economic impact on a substantial number of small 
    entities. As noted above, NHTSA tentatively concludes that only 
    Proposal Two, if adopted as a final rule, might result in slightly 
    increased costs to manufacturers, due to testing to new specifications. 
    Since the cost of new motor vehicles would not be affected, small 
    entities which purchase motor vehicles would similarly not be affected. 
    Therefore, an initial regulatory flexibility analysis has not been 
    prepared.
    
    3. National Environmental Policy Act
    
        NHTSA has also analyzed this proposed rule under the National 
    Environmental Policy Act and determined that it would not have any 
    significant impact on the quality of the human environment.
    
    4. Executive Order 12612 (Federalism)
    
        NHTSA has analyzed this proposed rule in accordance with the 
    principles and criteria contained in E.O. 12612, and has determined 
    that it would not have significant federalism implications to warrant 
    the preparation of a Federalism Assessment.
    
    5. Civil Justice Reform
    
        This proposed rule would not have any retroactive effect. Under 49 
    U.S.C. 30103, whenever a Federal motor vehicle safety standard is in 
    effect, a State may not adopt or maintain a safety standard applicable 
    to the same aspect of performance which is not identical to the Federal 
    standard, except to the extent that the State requirement imposes a 
    higher level of performance and applies only to vehicles procured for 
    the State's use. 49 U.S.C. 30161 sets forth a procedure for judicial 
    review of final rules establishing, amending or revoking Federal motor 
    vehicle safety standards. That section does not require submission of a 
    petition for reconsideration or other administrative proceedings before 
    parties may file suit in court.
