# DATES:

The effective date of the rule amending 49 CFR 571.127 published on November 26, 2024 is delayed until March 20, 2025.

# SUPPLEMENTARY INFORMATION:

                    In accordance with the memorandum of January 20, 2025, from the President to executive departments and agencies, entitled “Regulatory Freeze Pending Review,” [1]                                          this action temporarily delays the effective date of the rule entitled “Federal Motor Vehicle Safety Standards; Automatic Emergency Braking Systems for Light Vehicles,” published in the                     **Federal Register**                     on November 26, 2024, at 89 FR 93199.[2]                                          That rule made clarifying changes to the regulatory text of FMVSS No. 127 in response to petitions for reconsideration of the rule published May 9, 2024 titled “Federal Motor Vehicle Safety Standards; Automatic Emergency Braking Systems for Light Vehicles” filed by the Alliance for Automotive Innovation (the Alliance), Toyota Motor North America, Volkswagen Group of America, and Scuderia Cameron Glickenhaus, LLC, as well as a petition, treated by NHTSA as a petition for rulemaking, from Autotalks. It also denied several changes requested by petitioners.                

                    This action is exempt from notice and comment under 5 U.S.C. 553 and is effective immediately upon publication today in the                     **Federal Register**                    , based on the good cause exceptions in 5 U.S.C. 553(b)(B) and 553(d)(3), respectively. Seeking public comment is impracticable, unnecessary, and contrary to the public interest. The temporary delay in effective date is necessary to give Department officials the opportunity for further review and consideration of new regulations, consistent with the President's memorandum of January 20, 2025. Given the imminence of the effective date, seeking prior public comment on this temporary delay would have been impractical, as well as contrary to the public interest in the orderly promulgation and implementation of regulations. The imminence of the effective date is also good cause for making this action effective immediately upon publication.                

Issued in Washington, DC, under authority delegated in 49 CFR 1.95 and 501.5.

Peter Simshauser,

Chief Counsel.
