    ** There are five CRSs listed in both subparts C and D for testing purposes, so there are only 20 CRSs total in the appendix.

    Tables 2 and 3 below provide the detailed make and model information for NHTSA's deletions and additions to appendix A-1. There are some differences between the list of deletions and additions proposed in the NPRM and the deletions and additions adopted in this final rule, and a detailed discussion of those changes and the rationales behind those decisions can be found in the section below. All the deletions proposed in the NPRM are being adopted in this final rule, and the reasons for each deletion were discussed in detail in the NPRM. Generally, the proposed deletions were based on CRSs that did not offer any unique characteristics, CRSs that were produced in small quantities, or CRSs that are no longer in production and have not been for some time. Because the proposed deletions are all being adopted, NHTSA recommends that interested members of the public reference the NPRM for specific explanations of deletions for individual seats. There are two additional deletions and additions being adopted in this final rule. Because there are some differences between the proposed list of additions and deletions in the NPRM and the additions and deletions being adopted in this final rule, detailed explanations of those changes can be found in the following section. As discussed above, although this final rule says that the agency is “deleting” all seats from the current appendix A-1, those CRSs will still appear in the ( print page 67874) appendix to FMVSS No. 208, but they will appear under appendix A.

    Differences Between the NPRM and the Final Rule

    There are several differences between the 2020 NPRM and this Final Rule. Most notably, NHTSA decided to replace 6 of the 18 seats proposed as additions to appendix A-1 in the NPRM and update the model names for 6 of the proposed CRS additions. The agency made these decisions based on feedback from manufacturers and commenters. After publishing the NPRM, NHTSA contacted the CRS manufacturers of the proposed added seats to verify the production and design status of each proposed addition. The agency followed this same process when NHTSA last updated appendix A-1 in 2008.

    In the explanations below for why certain CRSs have been chosen as replacements for the proposed CRSs, the term “footprint” is used a number of times. For clarification, when using the term “footprint,” the agency is referring to the general size of the CRS base that contacts the seat cushion. The footprint on every CRS model is unique and some air bag suppression systems have difficulty sensing CRSs with certain footprints. ( print page 67875)

    The NPRM also proposed an update to model identification information for two seats: the Evenflo Discovery Adjust Right and the Britax Roundabout E9L02XX. After consulting with the manufacturers, instead of updating the model information for these two seats, the agency has decided to delete them from appendix A-1. Therefore, in addition to the changes to 12 of the 18 proposed additions to appendix A-1, NHTSA will be adding two different seats to replace the Evenflo Discovery Adjust Right and the Britax Roundabout E9L02XX as part of this Final Rule.

    A detailed discussion of the rationales for each change between the NPRM and Final Rule can be found in the subsections below.

    A. Deletion of the Evenflo Discovery Adjust Right and Addition of the Evenflo NurtureMax Into Subpart B

    As noted above, the NPRM proposed a model name update for the Evenflo Discovery Adjust Right to the Evenflo Nurture #362xxxxx. Based on input from Evenflo, and as shown on their website, the Evenflo Nurture model is no longer available. Because the goal of this Final Rule is to update appendix A-1 to include CRSs that are representative of today's CRS market and readily available, it would be illogical to include a CRS that is not listed on a manufacturer's website. Instead of keeping the Evenflo Discovery Adjust Right/Nurture in appendix A-1, this Final Rule will delete this CRS from subpart B, and will add the Evenflo NurtureMax as a replacement rear-facing CRS in subpart B. The Evenflo NurtureMax is not considered an equivalent replacement because it does not have the same structural design as the Discovery Adjust Right/Nurture, but it does have similar characteristics ( e.g., the Evenflo NurtureMax is a lightweight rear-facing CRS with a shorter than average footprint and it is a popular CRS in the U.S.).

    B. Addition of the Evenflo Litemax 35 #3305xxxxx Instead of the Evenflo Embrace Into Subpart B

    The NPRM proposed the addition of the Evenflo Embrace #315xxxxx, a rear-facing infant seat that was described as lightweight and popular, into subpart B. Based on feedback from the manufacturer and because the Evenflo Embrace model is no longer listed as part of the lineup of rear-facing CRSs on Evenflo's website, this model is no longer being added to the appendix. After evaluating other available CRSs with similar characteristics as the Evenflo Embrace the agency decided to add the Evenflo Litemax, which is also a popular, lightweight, rear-facing infant CRS with a long footprint.

    C. Addition of the Cybex Cloud Q With SensorSafe Instead of the Cybex Aton 2 Into Subpart B

    The NPRM proposed the addition of the Cybex Aton 2, a rear-facing infant seat, into subpart B. The NPRM described the Cybex Aton 2 as being a heavy infant seat and having a unique footprint because of its shape and because it is designed to accommodate a load leg. Due to feedback from the manufacturer and because the Cybex Aton 2 is no longer listed on Cybex's website, the agency is instead adding the Cybex Cloud Q with SensorSafe,[19] which has an essentially equivalent base as the Cybex Aton 2 and is just slightly heavier, which is acceptable since the Aton 2 was proposed as a heavy rear-facing CRS (see docketed Technical Assessment for dimensions and pictures). The Cybex Cloud Q also has a load leg like the Cybex Aton 2.

    D. Addition of the Nuna Pipa RX With Pipa RELX Base Instead of the Britax B-Safe 35 Into Subpart B

    The NPRM proposed the addition of the Britax B-Safe 35 #E1A72xx, a rear-facing infant seat, into subpart B. The NPRM described it as being heavy with a large footprint and as capturing a large portion of the infant CRS market. Based on input from Britax, we decided against including this CRS in the appendix. After evaluating other available rear-facing infant CRSs on the market, we are adding the Nuna Pipa RX with the Pipa RELX base, which has similar characteristics as the Britax B-Safe 35. The Nuna Pipa RX with the Pipa RELX base is a heavy rear-facing infant CRS, with a wide and long footprint.

    E. Deletion of the Britax Roundabout EL02XX and Addition of the Nuna Rava #CS05116CVR Into Subpart C

    As noted above, the NPRM proposed a model name update for the Britax Roundabout E9L02XX to reflect its new name, the Britax Allegiance #E9LR4xx. Based on input from Britax, and because the Britax Allegiance model is no longer listed on Britax's website as part of its lineup of CRSs, it would be illogical to include a CRS that is no longer part of Britax's CRS lineup. Instead of keeping the Britax Roundabout E9L02XX/Allegiance #E9LR4xx in appendix A-1, this final rule will delete this CRS from subpart C, and will add the Nuna Rava as a replacement convertible CRS in subpart C. The Nuna Rava has similar characteristics as the Britax Allegiance ( e.g., it is a heavy convertible CRS with a wide footprint; see the docketed Technical Assessment for dimensions and pictures). Additionally, the Nuna Rava is also a popular CRS.

    F. Addition of the Britax Poplar #E1C93xx Instead of the Britax Marathon ClickTight Into Subpart C

    The NPRM proposed the addition of the Britax Marathon ClickTight #E1A38xx, a convertible CRS, into subpart C. It was described as a heavy convertible CRS with a wide footprint. Based on feedback from Britax, we have decided against adding the proposed Marathon ClickTight model and we are instead adding the Britax Poplar #E1C93xx into subpart C. The manufacturer indicated that the Britax Poplar is dimensionally similar to the Britax Marathon ClickTight, so the agency views it is as a suitable alternative.

    G. Addition of the Graco Contender Slim Instead of the Graco Contender 65 Into Subpart C

    The NPRM proposed the addition of the Graco Contender 65, a convertible CRS, into subpart C. The NPRM described it as a lighter than average convertible CRS with a narrow and deep footprint. Based on feedback from the manufacturer we have decided not to add the proposed Contender model and the agency is instead adding the Graco Contender Slim model, which is essentially an equivalent model to the Graco Contender 65, into subpart C. Their footprint and dimensions are very similar, and the Contender Slim is a lighter than average convertible with a narrow footprint (see docketed Technical Assessment for dimensions and pictures).

    H. Addition of the Evenflo Chase Plus #307xxxxx Instead of the Evenflo Chase #306xxxxx Into Subparts C and D

    The NPRM proposed the addition of the Evenflo Chase #306xxxxx, a combination CRS, into subparts C and D. After consulting with the manufacturer, the agency has decided to instead add the Evenflo Chase Plus. The manufacturer indicated that the Evenflo Chase Plus will be more widely available than the Evenflo Chase, and that the CRSs are nearly equivalent (see docketed Technical Assessment for dimensions and pictures). It is also a popular combination CRS. Accordingly, the agency is adding the Evenflo Chase Plus #307xxxxx, into subparts C and D. ( print page 67876)

    I. Correction and Name Updates for 6 Proposed CRSs

    The NPRM proposed the addition of the Cybex Eternis, a 3-in-1 CRS, into subparts C and D. Based on input from the CRS manufacturer, the correct model name is the Cybex Eternis S with SensorSafe. Accordingly, the agency has added the “S” designation to the name of the CRS as well as the “SensorSafe” designation.

    The NPRM proposed the addition of the Safety 1st Dreamride SE LATCH #IC238xxx. Based on input from the manufacturer, the correct model name is the Safety 1st Dreamride with LATCH #IC238xxx. Accordingly, the agency has updated the name of this CRS as part of this final rule.

    The NPRM proposed the addition of the Graco 4Ever All-in-1. Based on input from the manufacturer, the correct model name is the Graco 4Ever DLX. Accordingly, the agency has updated the name of this CRS as part of this final rule.

    The NPRM proposed the addition of the Cosco Finale #BC121xxx. Based on input from the manufacturer, the updated model name for this seat is the Cosco Finale #BC110xxx. Accordingly, the agency has updated the name of this CRS as part of this final rule.

    The NPRM proposed the addition of the Graco Backless Turbobooster. Based on input from the manufacturer, the correct model name is the Graco Turbobooster Backless Booster Seat. Accordingly, the agency has updated the name of this CRS as part of this final rule.

    The NPRM proposed the addition of the Britax Grow with You #E1C19xx. Based on input from the manufacturer, the correct model name is the Britax Grow with You Clicktight #E1C19xx. Accordingly, the agency has updated the name of this CRS as part of this final rule.

    V. Discussion of Comments to the NPRM

    A. Summary of Comments

    There were eight comments submitted in response to the NPRM.[20] Commenters touched on a variety of topics, including the CRSs proposed in the NPRM, concerns about the frequency with which the agency updates appendix A-1, test procedures, the proposed regulatory text, and compliance dates. Some commenters also had concerns with the potential costs and effort necessary for manufacturers to comply with testing using the new CRSs proposed in the NPRM. The agency's summary of comments and responses can be found in the subsections below.

    B. The CRSs Proposed in the NPRM

    The Juvenile Products Manufacturers Association (JPMA) submitted a comment providing feedback on the CRSs NHTSA proposed in the NPRM. Table 4 shows the feedback JPMA provided in its comment on specific seats proposed in the NPRM, along with the agency's response to that feedback.

    Table 4—JPMA CRS Comments and NHTSA Responses

    NPRM proposed model JPMA suggested update Agency response
    Britax Allegiance #E9LR4xx Indicated incorrect model number listed in the NPRM; suggested using model #E1C14 This CRS is being replaced with a different CRS due to availability concerns.
    Britax B-Safe 35 #E1A72xx Indicated listed model number will be phased out in early 2021 This CRS is being replaced with a different CRS due to availability concerns.
    Britax Grow with You #E1C19xx Recommended replacing with non-ClickTight model #E1C144xx NHTSA chose the ClickTight model because it is the more popular version of the CRS. NHTSA has added the “ClickTight” designation to the name of the CRS.
    Cosco Finale #BC121xx Indicated the Cosco Finale #BC110xx is more widely available than the proposed model number NHTSA has confirmed with the manufacturer that the suggested model number #BC110xx is more widely available. NHTSA is replacing the proposed model with the model JPMA recommended as part of this final rule.
    Evenflo Generations 352xxxx Indicated the listed model is not produced, and recommended replacing with Evenflo EveryKid 393xxxx The Evenflo Generations CRS was a proposed deletion from the appendix. Because the last update to the appendix was in 2008, when NHTSA initiated this update, it evaluated the CRS market as a whole. Accordingly, the CRSs proposed as additions were not limited to the same brand of an existing CRS. Instead of focusing on selecting another seat from the same brand, the agency focused on finding seats with similar dimensions and footprints. In this case, NHTSA has decided on a different replacement seat.
    Evenflo Medallion 254 Indicated the listed model is no longer produced; recommended replacing with Evenflo SureRide 371xxxx The Evenflo Medallion CRS was a proposed deletion from the appendix. Because the last update to the appendix was in 2008, when NHTSA initiated this update, it evaluated the CRS market as a whole. Accordingly, the CRSs proposed as additions were not limited to the same brand of an existing CRS. Instead of focusing on selecting another seat from the same brand, the agency focused on finding seats with similar dimensions and footprints. In this case, NHTSA has decided on a different replacement seat.
    Evenflo Right Fit 245 Indicated the listed model is no longer produced; recommended replacing with Big Kid 365xxxx The Evenflo Right Fit CRS was a proposed deletion from the appendix. Because the last update to the appendix was in 2008, when NHTSA initiated this update, it evaluated the CRS market as a whole. Accordingly, the CRSs proposed as additions were not limited to the same brand of an existing CRS. Instead of focusing on selecting another seat from the same brand, the agency focused on finding seats with similar dimensions and footprints. In this case, NHTSA has decided on a different replacement seat.
    Evenflo Tribute V 379xxxx Indicated the listed model is no longer produced; recommended replacing with Evenflo EveryKid 381xxxx The Evenflo Tribute CRS was a proposed deletion from the appendix. Because the last update to the appendix was in 2008, when NHTSA initiated this update, it evaluated the CRS market as a whole. Accordingly, the CRSs proposed as additions were not limited to the same brand of an existing CRS. Instead of focusing on selecting another seat from the same brand, the agency focused on finding seats with similar dimensions and footprints. In this case, NHTSA has decided on a different replacement seat.
    ( print page 67877)
    Graco 4Ever All-in-1 Indicated that the currently listed name is for the original version that is only available at Costco; recommended replacing with 4ever DLX 4-in-1 model NHTSA has confirmed this comment with the manufacturer and did not find any significant size and weight differences between the two versions. NHTSA is adopting this recommendation as part of this final rule. The 4ever DLX 4-in-1 model will be reflected in the updated appendix.
    Graco Backless TurboBooster Recommended correcting name to “Graco Turbobooster Backless Booster Seat” This recommended edit is reflected in the appendix being adopted as part of this final rule.
    Graco Contender 65 Recommended correcting name to “Graco Contender 65 Convertible Car Seat” This CRS is being replaced with a different CRS due to availability concerns.
    Safety 1st Dreamride SE LATCH #IC238xxx Recommended correcting name to “Safety 1st Dreamride with LATCH” This recommended edit is reflected in the appendix being adopted as part of this final rule.

    C. Availability of the Safety 1st Dreamride SE Latch #IC238

    The Alliance for Automotive Innovation (The Alliance) commented specifically on NHTSA's proposed inclusion of the Safety 1st Dreamride SE Latch #IC238. The Alliance argued that, because the Safety 1st Dreamride SE Latch #IC238 is one of the only available infant car beds on the market, NHTSA should create a formal means for automakers to procure seats listed in appendix A-1.

    Agency Response: NHTSA will not be creating a formal process to acquire CRSs listed in appendix A-1 as part of this final rule. The Alliance is correct that part of the agency's rationale in updating appendix A-1 is to ensure manufacturers can more easily acquire the CRSs listed in appendix A-1. As stated previously, it can be difficult to acquire the CRSs currently listed in appendix A-1 because many of the CRSs have been discontinued by manufacturers. This final rule will resolve that issue by updating appendix A-1 to include CRSs currently on the market. However, under the Safety Act, manufacturers are required to self-certify their own motor vehicles and motor vehicle parts.[21] As part of this certification process, NHTSA strives to ensure that manufacturers and the public are aware of how the agency will test motor vehicles and motor vehicle parts for compliance with the FMVSS. That being said, once NHTSA has made clear how it will test a motor vehicle or motor vehicle part, it is up to the manufacturer to ensure its products comply. The agency believes it has significantly improved the ease with which manufacturers can acquire the CRSs in appendix A-1 by ensuring all CRSs in appendix A-1 are currently available for purchase. In particular, although the Safety 1st Dreamride SE Latch #IC238 is one of the only available infant car beds on the market, it is available for purchase by the public. Manufacturers do not need to rely on NHTSA to procure CRSs for them. Accordingly, the agency believes that manufacturers should easily be able to acquire the CRSs listed as part of this final rule. For the reasons discussed above, NHTSA will not be creating a formal process for manufacturers to acquire the CRSs listed in appendix A-1 as part of this final rule.

    D. Frequency of Updates to the Appendix

    The Automotive Safety Council commented that it would like NHTSA to adopt an official frequency with which the agency will update appendix A-1 going forward. JPMA also mentioned in its comment that it would appreciate more frequent updates to appendix A-1 from NHTSA. The Alliance also commented on the need for a more reliable and consistent manner of updating the appendix in its August 2023 supplemental comments.

    Agency Response: NHTSA will not be adopting a specific frequency for updating appendix A-1 as part of this final rule. As discussed earlier in this preamble as well as in the NPRM, the agency is aware that a significant amount of time has passed since it last updated appendix A-1 in 2008. The agency is aware that this time-lapse has rendered appendix A-1 outdated, and many of the seats listed in appendix A-1 are no longer in production, which makes it difficult for manufacturers to acquire certain CRSs that NHTSA currently tests with. One of NHTSA's goals with this final rule is to ensure manufacturers can easily acquire the CRSs listed in appendix A-1. Another goal with this final rule is to ensure the CRSs NHTSA uses to test for compliance with FMVSS No. 208 are representative of the CRS market. The agency believes that committing to a specific frequency to update appendix A-1 would not align with the ever-changing CRS market. Having the discretion necessary to choose when to update appendix A-1 will allow the agency to adapt as the CRS market adapts. Furthermore, committing to a specified time frame for updating the appendix would likely interfere with the agency's ability to manage its rulemaking resources as it deems appropriate in light of other priorities and statutory mandates and could hamper its ability to respond quickly to changes in the CRS industry or air bag system designs. As such, NHTSA is not adopting a specific frequency to update appendix A-1 as part of this final rule.

    E. Test Procedures

    i. Testing With the CRABI Dummy

    The Alliance indicated in its comment that it would like clarification on test procedure installation for two forward-facing CRSs proposed in the NPRM. Specifically, the Alliance requested that NHTSA explain how it should test the Cosco Finale DX #BC121 and the Chicco MyFit #04079783-0070 with the 12-month-old CRABI dummy when the owner's manuals for both of those seats indicate that those CRSs are designed to be used for children weighing more than the 12-month-old CRABI dummy weighs. The Alliance reiterated its concerns in its August 2023 supplemental comments.

    Agency Response: As discussed above, NHTSA is correcting the name of the Cosco Finale DX #BC121 and is instead including the Cosco Finale #BC110 as part of this final rule. According to the manufacturer, this is merely a model name change and the seat design and intended use are functionally the same, meaning the Alliance's comment still applies. FMVSS No. 208, S19.2.1, specifies the use of the 12-month-old dummy for suppression testing in any of the CRSs listed in the appendix subparts C and D as appropriate. The term “as appropriate” is informative here, as it makes clear that NHTSA will only suppression test a seat in appendix A-1 subparts C and D with the 12-month-old dummy if it is appropriate to do so with that seat. As discussed in the ( print page 67878) background section above, FMVSS No. 208 sets out testing requirements for advanced air bag systems using the 12-month-old CRABI dummy, the 3-year-old child dummy, and the 6-year-old child dummy. For all seats listed in appendix A-1, NHTSA will only test with the dummies that are the appropriate size for each respective CRS according to the manufacturer's instructions. Accordingly, because the Cosco Finale DX #BC121 and the Chicco MyFit #04079783-0070 are CRSs that are designed to restrain children who weigh more than the 12-month-old CRABI dummy, NHTSA would not suppression test with the 12-month-old CRABI dummy for those CRSs.

    ii. Seat Belt Load Requirement

    The Alliance requested clarification of the seat belt cinching requirement listed in the FMVSS No. 208 test procedures. The Alliance commented that for certain CRSs listed in the NPRM with belt tensioning devices, “it is possible to exceed the 134 N belt load by 80-106 N if slack is removed from the belt prior to applying the child seat belt tensioning mechanism.” Furthermore, the Alliance indicated that it is concerned that in the field, these belt tensioning mechanisms can exceed the belt tension in the manufacturer's compliance testing, and, in combination with heavier CRSs, could increase the risk of an undesired air bag deployment ( e.g., a child heavier than the dummy and excessive belt load due to child seat belt tensioning systems could be misclassified as a small adult occupant).

    Agency Response: In response to this comment, NHTSA performed further testing with CRSs proposed in the NPRM that have belt tensioning mechanisms. The agency acknowledges that when these seats are installed using the manufacturers' instructions, these seats automatically tension past the maximum tension of 134 N described in FMVSS No. 208 S20.2.1.5(c). The tension that these seats tension to varies depending on the seat they are installed in as well as the specific CRS. Accordingly, the agency acknowledges that if the manufacturers' instructions for these seats are followed, it would likely not be possible to test within the tension range outlined in S20.2.1.5(c).

    The agency has decided to include three seats with belt tensioning systems as part of this final rule, despite the fact that they likely cannot be installed by following the CRS manufacturers' instructions to properly perform the test procedure outlined in S20.2.1.5(c). It is important to note that, for the S20.2.1.5 test procedure, the standard instructs the test conductor to “secure the child restraint by following, to the extent possible, the child restraint manufacturer's instructions regarding proper installation . . .” (emphasis added).

    The agency is aware that there are some CRSs on the market that are equipped with belt tensioning systems that may tension past the maximum 134 N outlined in S20.2.1.5. Accordingly, the agency believes it is important to include these CRSs in appendix A, as they represent a segment of the CRS market. Through NHTSA's research on belt tensioning seats, the agency discovered that it is possible to reduce the tension that the belt tensioning devices automatically ratchet to by introducing extra belt webbing when installing the CRS on the vehicle seat. To clarify how to test with these CRSs according to the parameters outlined in S20.2.1.5(c), NHTSA will update its compliance test procedures to instruct labs contracted with NHTSA to introduce extra belt webbing when installing CRSs with belt tensioning devices. The amount of extra webbing that needs to be introduced depends on the CRS and the vehicle seat the CRS is installed on, so the agency will include in the compliance test procedure a method for achieving the required belt tension within the allowable range of zero to 134 N. The agency believes this procedure is consistent with the requirements of paragraph S20.2.1.5(c) because of the “to the extent possible” language used in that paragraph.

    The agency decided to keep these CRSs with belt tensioning devices as part of this final rule for multiple reasons. First, as discussed in the NPRM and in the section above describing the difference between the NPRM and the final rule, these seats (Cybex Cloud Q, Britax Poplar, and Britax Grow With You ClickTight) represent important parts of the CRS market when it comes to the characteristics of each CRS ( e.g., weight, footprint dimensions and designs). The agency believes that because these seats are part of the CRS market and because they have characteristics the agency wants to include in the appendix for testing the effectiveness of the air bag suppression systems, these seats are worth keeping as part of the amended appendix A-1. Second, these CRSs equipped with belt tensioning devices were not available the last time appendix A-1 was updated in 2008. It is possible that CRSs equipped with belt tensioning devices will become more popular as time goes on. Accordingly, the agency believes it is important to have CRSs equipped with belt tensioning devices as part of appendix A. Although the test procedure will test at a lower tension than these three CRSs typically tension to, NHTSA believes that there is still a safety benefit to testing these CRSs at a reduced tension. Specifically, if an advanced air bag system fails to suppress at a tension in the zero to 134 N range, it is likely that that advanced air bag system would also fail the test at the tighter tension range that the belt tensioning device would usually ratchet to. Accordingly, vehicle manufacturers will know if their air bag suppression systems are compliant with the specific weight and footprint of these CRSs, with the belt tensioned to the appropriate test range. For the reasons listed above, the agency has decided to keep the CRSs with belt tensioning devices as part of this final rule and will update the compliance test procedures to instruct labs on how to install the CRSs to the tension range outlined in S20.2.1.5(c).

    iii. Compliance Concerns With New Heavier CRSs

    The Alliance requested that NHTSA reconsider the CRSs proposed in the NPRM, due to concern about the overall shift to include heavier CRSs in appendix A-1. They further stated that the NPRM did “not sufficiently address the potential for misclassification of occupants. The size and weight of CRSs continue to grow, bringing them (combined with their intended child occupants) closer to the size of small adults. The narrowing of this gap creates an increasing risk of misclassifications by vehicle occupant classification systems (OCS), potentially leading to air bag inflation in instances when suppression might be the safer outcome. Significant changes to the air bag systems and related software will be required to address this matter, along with changes to the vehicle instrument panels to accommodate the new systems.”

    The Alliance reiterated these concerns in one of its supplemental comments. The Alliance argued that NHTSA's crash data demonstrates that injury and fatality exposure rates are far greater for smaller stature occupants in fatal crashes ( i.e., over 13 years old) than for younger children ( i.e., under 6 years old) because most younger children are seated in the back seat of vehicles.[22] According to the Alliance, this reflects that the largest group at risk of injury from frontal air bags is smaller statured passengers, not passengers seated in CRSs. The Alliance argued that this further supports their argument about ( print page 67879) the potential harm of misclassification by OCSs.

    The Alliance did not provide actual vehicle compliance test data to support their claims with regards to the performance of current systems with the heavier CRSs. The Alliance suggested that “NHTSA should conduct further analysis to assess the regulatory impact on existing vehicle designs when including CRS that are significantly above the current threshold values established in appendix A-1, and the potential impact this may have on overall occupant safety.” Furthermore, the Alliance argued that the weight of the heavier CRSs in combination with the 6-year-old dummy would begin to overlap with the air bag activation threshold leading to misclassification by the occupant detection system.

    Agency Response: The commenters are correct in their assessment that the proposed CRSs in the appendix A-1 update will be heavier overall than the previous version of the appendix, which was last updated in 2008. Since then, the CRS market has evolved significantly. NHTSA has conducted an analysis of recent Ease of Use program data (2015-2020 yearly data) and found an increase in the yearly average weight of boosters and CRSs that can be used as booster seats, which can be seen in table 5 below.

    Table 5—Average Weight of Booster Seats and Available CRS Models That Can Be Used as Booster Seats

    Booster seats and CRSs that can be used as booster seats
    Year Average weight (lb) Count (n)
    2015 12.79 83
    2016 12.89 89
    2017 13.19 112
    2018 14.18 124
    2019 14.86 121
    2020 14.92 120

    Additionally, the agency analyzed Ease of Use data as far back as 2012 to look at whether heavier CRSs were available at that time as well. NHTSA found booster seats, and CRSs that can be used as booster seats, that are heavier than or have a similar weight as the heavy CRSs identified by the Alliance that have been available as far back as 2012. Examples of such CRSs can be seen in table 6.

    * These boosters/CRSs were available in subsequent years and possibly previous years as well. We have only identified the earliest year the CRS was in the Ease of Use program based on the range of years examined.

    The Alliance requested that NHTSA include CRSs that are consistent with the weights of the CRSs currently listed in the appendix. Although the agency acknowledges that manufacturers may have to make design changes to ensure their advanced air bag systems remain compliant with FMVSS No. 208, NHTSA's top priority is passenger safety. As shown above, there is a clear trend toward CRSs increasing in weight. To ensure vehicle air bag suppression systems protect passengers, the agency must ensure that the CRSs being used to test those systems are representative of the current CRS market. Basing the weights of the CRSs included in appendix A-1 off the CRS market in 2008 would not reflect the CRSs that most current parents and caretakers use currently. One of NHTSA's goals with this final rule is to make the FMVSS No. 208 test procedures more representative of the real world, and continuing to test with CRSs from 2008 would do the opposite.

    Furthermore, since the inception of the Advance Air Bag Rule, the agency has made clear that it is incumbent on vehicle manufacturers to perform their due diligence by developing and testing their advanced air bag systems with CRSs that are not limited to appendix A.[23] Accordingly, it is reasonable to ( print page 67880) assume that many manufacturers test their advanced air bag systems with more CRSs beyond what is listed in appendix A-1.

    Lastly, NHTSA initiated testing to investigate the Alliance's concerns with the heavier CRSs. Thirteen vehicles were tested, and each vehicle was tested with the CRSs in varying modes. The reports from this testing will be placed in the docket for this rulemaking.

    This research demonstrated that four of the 13 vehicles tested were able to suppress the air bag with all the CRSs used for testing, including the three heavier CRSs identified by the Alliance. The passenger air bag activation weight threshold was measured for each vehicle and the thresholds ranged from 55-85 lb. The weight threshold for the four vehicles that suppressed the air bag for all the CRSs and modes tested ranged from 56-77 lb. Further, 8 of the 13 vehicles complied with the requirements with at least 2 of the 3 heavy CRSs identified by the Alliance.

    The agency's testing also revealed that the weight of the CRS does not necessarily ultimately determine whether an air bag suppression system activates. For instance, one of the tested vehicles (with an air bag suppression system weight threshold of 73 lb) was able to meet the suppression requirements with two of the three CRSs identified by the Alliance (Cybex Eternis and Britax Grow With You), but did not comply with the Chicco Myfit, which was the lightest of the three. This result seemed to be related to how the Chicco MyFit's footprint loaded the system's pressure sensitive bladder.

    The agency testing has shown inconsistent performance for heavier CRSs. However, it is clear from the results that systems can be designed to correctly identify these CRSs and appropriately suppress the air bag. The failure of some vehicles to suppress the air bag in the presence of some of the CRSs is concerning and supports the need for expeditious inclusion of heavier CRSs in the appendix.

    iv. Safety Need for Appendix Update

    The Alliance commented on the limited exposure to air bags for children in CRSs since most children are placed in the rear seats and because most children in the front passenger seat are restrained only by seat belts. The Alliance further noted that “the CRS list currently defined in FMVSS 208 appendix A-1 has been successful in shaping design countermeasures that support a positive downward trend in injuries and fatalities for both child- and small-stature occupants seated in the right-front seating position.”

    Agency Response: NHTSA acknowledges and is encouraged by the positive trend of seating children in the back seat. Nonetheless, children are sometimes still restrained in a CRS in the front seat. Furthermore, as discussed above, there is a clear market trend in CRSs becoming heavier on average. This is at least in part due to the rise of the all-in-one (also known as the 3-in-one) seat, which has become popular with caregivers as they only have to purchase one seat for their child, instead of buying new seats as their child grows. Offerings in the all-in-one CRS category have significantly grown in the CRS industry over the past several years. This is evident in the list provided by American Academy of Pediatrics of available all-in-one CRSs for 2023.[24] Additionally, using the 2015-2020 Ease of Use data, the agency looked at the number of all-in-one and combination CRSs and found an increase in the number of these types of CRSs from 84 in 2015 to 120 in 2020. Because the market trends point to an overall increase in CRS weight, NHTSA believes there is a critical safety need to have heavier seats included as part of appendix A-1.

    F. Comments on the Proposed Regulatory Text

    In the NPRM, the agency proposed specific amendments to FMVSS No. 208, to remove the current appendix A (which has been phased out), redesignate appendix A-1 as appendix A, and add the new list of CRSs as appendix A-1.

    The Alliance commented that, “Comparing the NPRM which was published on October 29, 2020, and the current standard, it seems that `S21' has been accidentally deleted. As NHTSA's intention was to redesignate `appendix A-1' of the current regulation as `appendix A' in the October 29, 2020, NPRM, we believe the section numbers in subpart D should be the same ( i.e. should refer to `S21 or S23'). See FR page 68552, proposed FMVSS 208, section D of appendix A.” The Alliance also commented that “[t]here appears to be an inconsistency in the proposed regulations. Comparing proposed FMVSS 208 S14.8 vs. Part 585.35 and Part 585.36, it seems that `first' in S14.8 should be `second.' ”

    Agency Response: NHTSA concurs with these comments and has corrected the regulatory text as part of this final rule. This amendment is reflected in the adopted regulatory text below.

    G. Comments on the Compliance Date

    In the NPRM, the agency proposed that the compliance date for the proposed requirements be phased in such that at least 50 percent of a manufacturer's vehicles manufactured on or after the first September 1st after the publication date of the final rule would have to be certified as meeting FMVSS No. 208 when tested with the CRSs on the revised appendix A-1, and all vehicles manufactured on or after the second September 1st after the publication date of the final rule would have to be so certified.

    The Alliance expressed concerns with the proposed compliance date in both its initial comment and one of its supplemental comments. In its initial comment it argued that, due to the increased weight of the CRSs being tested under the proposed update, manufacturers would have to take a series of steps to ensure compliance. The Alliance wrote:

    “Substantial testing will be required to assess the performance of occupant classification systems with the heavier CRS installed. Such testing may identify the need for air bag system design changes. Changes to air bag size, shape, and inflators may necessitate changes to instrument panel design. Suppression may no longer be an option for some models with weight-based occupant classification sensors. Those models may have to switch from suppression to LRD approaches. In that case, the air bag module as well as the instrument panel may also need to be re-engineered. Significant changes may be required to accommodate the new systems. Our initial study indicates that, after further consideration of this matter by the affected parties and development of technical solutions, additional lead-time will likely be needed to implement these strategies, beyond what is proposed by the agency in the NPRM. This scenario will require full frontal crash development which typically takes more than two years.”

    In its supplemental comment, the Alliance requested that the lead time be extended by two years with an additional four-year phase-in to allow for manufacturers' evaluation and implementation of design changes to advanced air bag systems. ( print page 67881)

    Agency Response: As discussed throughout this preamble, the CRS market has been trending toward heavier CRSs for some time. Although appendix A-1 provides manufacturers with a list of seats that NHTSA will test to determine compliance with FMVSS No. 208, the agency made it clear in the Advanced Air Bag Final Rule that manufacturers have a responsibility to ensure that their advanced airbag systems suppress deployment with all seats that are available on the CRS market. Accordingly, if manufacturers have been paying attention to the CRS market, they should have already begun the process of implementing heavier CRSs into their test programs. Furthermore, delaying compliance with the updated appendix would likely result in availability issues for the CRSs being added to the appendix given the frequent change in CRS model names, designs, or discontinuation of CRSs.

    As part of NHTSA's own research, the agency acknowledges that some advanced air bag systems will likely have to undergo adjustments to comply with the updated appendix A-1. In response to commenters' compliance concerns as well as the agency's testing, the agency has decided that the phase-in of the revised appendix will be implemented in two stages. To ease the burden on manufacturers, NHTSA is amending the compliance phase-in to the following: Forty percent of all of a manufacturer's light vehicles must comply with the revised appendix by September 1, 2025, and all light vehicles must be fully compliant no later than September 1, 2026. We are also allowing optional early compliance. This change provides relief for an additional 10% of vehicles in the first part of the phase-in. However, NHTSA does not believe that an extension of the full compliance date beyond the second part of the phase-in is warranted or advisable. Among other risks, any additional delay raises the chances of inadvertently unsuppressed air bag systems in vehicles where certain heavier CRSs have been placed in the front seat. The agency encourages vehicle manufacturers to acquire sufficient inventory of the CRSs when the final rule is published to mitigate availability issues in the future.

    VI. Discussion of Benefits and Costs Associated With the Final Rule

    The NPRM discussed how this rule does not amend any of the FMVSS No. 208 performance test requirements; it merely updates the list of CRSs NHTSA may use for advanced air bag compliance tests. It further explained that we cannot quantify the incremental benefits of testing with these new CRSs over those listed in the current appendix A-1, due to a lack of field performance test data, but that updating the CRSs used to assess the performance of advanced air bags addresses that potential issue by enabling manufacturers to design advanced air bag systems to factor in the features and characteristics of the CRSs used today.

    With regards to the costs associated with the rule, the NPRM stated that the rule would result in a nominal cost to vehicle manufacturers for the purchase of the new CRSs. It provided a conservative cost estimate for the one additional CRS and then amortized this cost over 10 years and 16 million vehicles to get an annual per vehicle cost estimate. Essentially, based on the cost of a complete set of all the CRSs added, $3,364, it estimated the cost for the one additional CRS being added as $168.20 (1/20th of total cost). Then, based on an estimated 248 production lines and the assumption that vehicle manufacturers will purchase 10 sets of CRSs, the NPRM estimated that the total undiscounted 10-year cost to all vehicle manufacturers cumulatively would be $417,136 ($168.20 × 248 × 10). Assuming an annual production of 16 million vehicles, there would be 160 million vehicles for the same time period (16 million × 10 years). Thus, the NPRM provided an annual per-vehicle cost estimate of $0.0026 ($417,136/160 million).

    These cost estimates have been updated for this final rule, given the differences between the final rule and NPRM in terms of the new CRSs being added. NHTSA observed an increased cost for most of the NPRM proposed CRSs that were not affected in the final rule. The estimated cost of a complete set of CRSs is now $4,322.40 (in 2023 dollars). Therefore, the cost for the one additional CRS being added is $216.12. The updated annual per vehicle cost is $0.0033 (($216.12 × 248 × 10)/160 million).

    The agency believes this figure is an overestimate for the following reasons. NHTSA acknowledges that some manufacturers may purchase fewer of some CRSs (if their vehicles are equipped with air bag suppression systems) or more of some CRSs (if they are equipped with LRD air bags).[25] Therefore, we consider 10 a high estimate for the number of complete sets vehicle manufacturers will purchase, because, based on our experience, one set can be used to certify several vehicle models for several years.

    In its August 2023 supplemental comments, the Alliance also commented on the increased burden of dealing with the aftermarket acquisition process for CRSs that are no longer widely available. Accordingly, the agency believes vehicle manufacturers would also save an unquantified amount of time and money because they will no longer need to acquire the existing appendix A-1 CRSs that are out of production through aftermarket sourcing. In addition, it is reasonable to assume vehicle manufacturers are testing their advanced air bag systems with CRSs that are not in the appendix, so it is possible that they already possess and have conducted testing with some of the proposed CRS additions, particularly the popular CRSs.

    VII. Regulatory Analyses

    Executive Order 12866, Executive Order 14904, Executive Order 13563, and DOT Regulatory Policies and Procedures

    NHTSA has considered the potential impact of this final rule under Executive Order 12866, Executive Order 14094, Executive Order 13563, DOT Order 2100.6A, and the Department of Transportation's regulatory policies and procedures. This final rule is not considered to be significant under the Department of Transportation's regulatory policies and procedures.[26]

    This final rule makes several changes to FMVSS No. 208; specifically, the changes amend appendix A-1 of FMVSS No. 208, which lists the child restraint systems NHTSA uses in compliance testing of advanced air bag systems. Due to the changes in the CRSs proposed in the NPRM versus the CRSs being adopted as part of this final rule, the agency updated the costs in preparation for this final rule. The agency estimates that compliance with the final rule would result in a nominal total annual cost to all vehicle manufacturers cumulatively of $535,977 (over ten years) for the purchase of the new CRSs. Assuming an annual production of 16 million vehicles (with a GVWR of 8,500 lb or less), the per- ( print page 67882) vehicle cost is $0.0033 annually for the purchase of the new CRSs. More information can be found in the “Discussion of Benefits and Costs Associated with the Final Rule” section above. The minimal impacts of this final rule did not warrant the preparation of a regulatory evaluation.

    Regulatory Flexibility Act

    In compliance with the Regulatory Flexibility Act, 5 U.S.C. 601 et seq., NHTSA has evaluated the effects of this action on small entities. I hereby certify that this final rule will not have a significant impact on a substantial number of small entities. The final rule affects motor vehicle manufacturers, multistage manufacturers, and alterers, but the entities that qualify as small businesses would not be significantly affected by this rulemaking because they are already required to comply with the advanced air bag requirements. This final rule would not establish new requirements, but instead would only adjust and update the CRSs used in FMVSS No. 208's test procedures for advanced air bags. The small manufacturers would continue to certify their vehicles as meeting the advanced air bag requirements using the same methods and procedures they use today, only with more current CRSs.

    Federalism

    NHTSA has examined this final rule pursuant to E.O. 13132 (64 FR 43255, August 10, 1999) and concluded that no additional consultation with States, local governments, or their representatives is mandated beyond the rulemaking process. The agency has concluded that the rulemaking would not have sufficient federalism implications to warrant consultation with State and local officials or the preparation of a federalism summary impact statement. This final rule would not have substantial direct effects on the States, on the relationship between the National Government and the States, or on the distribution of power and responsibilities among the various levels of government.

    NHTSA rules can have a preemptive effect in two ways. First, the National Traffic and Motor Vehicle Safety Act contains an express preemption provision stating that, if NHTSA has established a standard for an aspect of motor vehicle or motor vehicle equipment performance a State may only prescribe or continue in effect a standard for that same aspect of performance if the State standard is identical to the Federal standard. 49 U.S.C. 30103(b)(1). It is this statutory command by Congress that preempts any non-identical State legislative and administrative law addressing the same aspect of performance.

    The express preemption provision described above is subject to a savings clause under which “[c]ompliance with a motor vehicle safety standard prescribed under this chapter does not exempt a person from liability at common law.” 49 U.S.C. 30103(e). Pursuant to this provision, State common law tort causes of action against motor vehicle manufacturers that might otherwise be preempted by the express preemption provision are generally preserved.

    NHTSA rules can also preempt State law is if complying with the FMVSS would render the motor vehicle manufacturers liable under State tort law. Because most NHTSA standards established by an FMVSS are minimum standards, a State common law tort cause of action that seeks to impose a higher standard on motor vehicle manufacturers will generally not be preempted. However, if and when such a conflict does exist—for example, when the standard at issue is both a minimum and a maximum standard—the State common law tort cause of action is impliedly preempted. See Geier v. American Honda Motor Co., 529 U.S. 861 (2000).

    Pursuant to E.O. 13132, NHTSA has considered whether this final rule could or should preempt State common law causes of action. The agency's ability to announce its conclusion regarding the preemptive effect of one of its rules reduces the likelihood that preemption will be an issue in any subsequent tort litigation. To this end, the agency has examined the nature ( e.g., the language and structure of the regulatory text) and objectives of this final rule and finds that this final rule, like many NHTSA rules, prescribes only a minimum safety standard. Accordingly, NHTSA does not intend that this final rule preempt state tort law that would effectively impose a higher standard on motor vehicle manufacturers than that established by this final rule. Establishment of a higher standard by means of State tort law would not conflict with the minimum standard finalized in this document. Without any conflict, there could not be any implied preemption of a State common law tort cause of action.

    National Environmental Policy Act

    NHTSA has analyzed this final rule for the purposes of the National Environmental Policy Act. The agency has determined that implementation of this action would not have any significant impact on the quality of the human environment.

    Paperwork Reduction Act

    Under the procedures established by the Paperwork Reduction Act of 1995 (PRA) (44 U.S.C. 3501, et. seq.), a Federal agency must request and receive approval from the Office of Management and Budget (OMB) before it collects certain information from the public and a person is not required to respond to a collection of information by a Federal agency unless the collection displays a valid OMB control number. This rulemaking creates new information collection requirements for phase-in reporting and record retention requirements.

    In compliance with the requirements of the PRA, NHTSA is separately publishing a notice requesting comment on NHTSA's intention to request approval for a reinstatement with modification of a previously approved information collection request. Specifically, NHTSA is requesting reinstatement of the information collection request (ICR) with OMB Control No. 2127-0535 and requesting that 49 CFR part 585 be renamed “Phase-In Reporting Requirements.” This ICR will be used to consolidate all phase-in reporting requirements that are included in 49 CFR part 585 and was chosen because the OMB Control Number is currently listed in 49 CFR part 509 as being associated with information collections contained in part 585.

    NHTSA's ICR describes the nature of the information collections and their expected burden. The ICR is to request approval for two new information collections for mandatory phase-in reporting for vehicle manufacturers and related information collections.

    With this final rule NHTSA is amending Federal Motor FMVSS No. 208, “Occupant crash protection,” to update the child restraint systems (CRSs) listed in appendix A-1 of the standard. NHTSA uses the CRSs in appendix A-1 to test the performance of advanced air bag suppression and low risk deployment systems in either suppressing or deploying the air bag in a low-risk manner in the presence of a CRS. The proposed amendments would ensure that the CRSs used by NHTSA to test advanced air bags are representative of the current CRS fleet and would make it easier for vehicle manufacturers and test laboratories to acquire CRSs for testing purposes.

    As part of the update to FMVSS No. 208, there will be a phase-in of the requirements for testing with the new CRSs listed in appendix A-1. This phase-in of the amendment gives vehicle manufacturers reasonable time ( print page 67883) to certify their advanced air bag systems using the new CRSs. As with all phase-ins, the agency is adopting a reporting and recordkeeping requirement to facilitate the agency's enforcement of the standard by aiding NHTSA in determining whether a manufacturer has complied with the phase-in requirements during the phase-in period. These requirements are found in 49 CFR part 585, “Phase-In Reporting Requirements.” The reporting and recordkeeping requirements require that manufacturers submit an annual production report to NHTSA that includes the number of vehicles manufactured in the current production year and the production of complying vehicles and that they retain records of compliance with the phase-in requirements for five years. NHTSA estimates this collection will impact 22 manufacturers each year and will have a total annual burden of approximately 22 hours and $0.

    Unfunded Mandates Reform Act (UMRA)

    The Unfunded Mandates Reform Act of 1995 (UMRA) requires Federal agencies to prepare a written assessment of the costs, benefits, and other effects of proposed or final rules that include a Federal mandate likely to result in the expenditure by State, local or tribal governments, in the aggregate, or by the private sector, of more than $100 million annually (adjusted annually for inflation, with base year of 1995). UMRA also requires an agency issuing an NPRM or final rule subject to the Act to select the “least costly, most cost-effective or least burdensome alternative that achieves the objectives of the rule.” This final rule would not result in a Federal mandate that will likely result in the expenditure by State, local, or tribal governments, in the aggregate, or by the private sector, of more than $100 million annually (adjusted annually for inflation, with base year of 1995).

    Executive Order 12778 (Civil Justice Reform)

    When promulgating a regulation, agencies are required under Executive Order 12988 to make every reasonable effort to ensure that the regulation, as appropriate: (1) specifies in clear language the preemptive effect; (2) specifies in clear language the effect on existing Federal law or regulation, including all provisions repealed, circumscribed, displaced, impaired, or modified; (3) provides a clear legal standard for affected conduct rather than a general standard, while promoting simplification and burden reduction; (4) specifies in clear language the retroactive effect; (5) specifies whether administrative proceedings are to be required before parties may file suit in court; (6) explicitly or implicitly defines key terms; and (7) addresses other important issues affecting clarity and general draftsmanship of regulations.

    Pursuant to this Order, NHTSA notes as follows. The preemptive effect of this final rule is discussed above. NHTSA notes further that there is no requirement that an individual submit a petition for reconsideration or pursue other administrative proceedings before they may file suit in court.

    National Technology Transfer and Advancement Act

    Under the National Technology Transfer and Advancement Act of 1995 (NTTAA) (Pub. L. 104-113), “all Federal agencies and departments shall use technical standards that are developed or adopted by voluntary consensus standards bodies, using such technical standards as a means to carry out policy objectives or activities determined by the agencies and departments.” Voluntary consensus standards are technical standards ( e.g., materials specifications, test methods, sampling procedures, and business practices) that are developed or adopted by voluntary consensus standards bodies, such as the International Organization for Standardization (ISO) and the Society of Automotive Engineers (SAE). The NTTAA directs this agency to provide Congress, through OMB, explanations when we decide not to use available and applicable voluntary consensus standards. There are no voluntary consensus standards developed by voluntary consensus standards bodies pertaining to this final rule.

    Plain Language Requirement

    Executive Order 12866 requires each agency to write all rules in plain language. Application of the principles of plain language includes consideration of the following questions:

    • Have we organized the material to suit the public's needs?
    • Are the requirements in the rule clearly stated?
    • Does the rule contain technical language or jargon that isn't clear?
    • Would a different format (grouping and order of sections, use of headings, paragraphing) make the rule easier to understand?
    • Would more (but shorter) sections be better?
    • Could we improve clarity by adding tables, lists, or diagrams?
    • What else could we do to make the rule easier to understand?

    NHTSA has considered these questions and attempted to use plain language in promulgating this final rule. Please inform the agency if you can suggest how NHTSA can improve its use of plain language.

    Regulatory Identifier Number (RIN)

    The Department of Transportation assigns a regulation identifier number (RIN) 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 at the beginning of this notice may be used to find this action in the Unified Agenda.
