This final rule adopts a new Federal Motor Vehicle Safety Standard to require automatic emergency braking (AEB), including pedestrian AEB (PAEB), systems on light vehicles. An AEB system uses various sensor technologies and sub-systems that work together to detect when the vehicle is in a crash imminent situation, to automatically apply the vehicle brakes if the driver has not done so, or to apply more braking force to supplement the driver's braking. This final rule specifies that an AEB system must detect and react to an imminent crash with both a lead vehicle or a pedestrian. This final rule fulfills a mandate under the Bipartisan Infrastructure Law (BIL) directing the Department to promulgate a rule to require that all passenger vehicles be equipped with an AEB system. The purpose of this final rule is to reduce the number of deaths and injuries that result from crashes in which drivers do not apply the brakes or fail to apply sufficient braking power to avoid or mitigate a crash, and to reduce the consequences of such crashes.Effective Date: This rule is effective 8 July 2024.    IBR date: The incorporation by reference of certain material listed in the rule is approved by the Director of the Federal Register beginning 8 July 2024. The incorporation by reference of certain other material listed in the rule was approved by the Director of the Federal Register as of 8 July 2022.    Compliance Date: 1 September 2029. However, vehicles produced by small-volume manufacturers, final-stage manufacturers, and alterers must be equipped with a compliant AEB system by 1 September 2030.    Petitions for reconsideration: Petitions for reconsideration of this final rule must be received not later than 24 June 2024.Title 49 Code of Federal Regulations (CFR) Parts 571595, and 596 (currently reserved).This final rule and the notice of proposed rulemaking notified as G/TBT/N/USA/2007 are identified by Docket Number NHTSA-2023-0021. The Docket Folder is available on Regulations.gov at https://www.regulations.gov/docket/NHTSA-2023-0021/document and provides access to primary and supporting documents as well as comments received. Documents are also accessible from Regulations.gov by searching the Docket Number. WTO Members and their stakeholders are asked to submit petitions for reconsideration to the USA TBT Enquiry Point by or before 4pmEastern Time on 24 June 2024. Petitions for reconsideration received by the USA TBT Enquiry Point from WTO Members and their stakeholders will be shared with the DOT and will also be submitted to the Docket on Regulations.gov if received within the comment period.
