Response to Petition for Reconsideration, Federal Motor Vehicle Safety Standards; Seat Belt Assembly Anchorages

NHTSA published a final rule on September 17, 2024 that amended the regulation on seat belt assembly anchorages. The final rule updated the test procedure for existing test devices and added an alternative test device as a compliance option. In response to the 2024 final rule, the agency received a petition for reconsideration from the Truck and Engine Manufacturers Association. After considering the petition, NHTSA is proposing to delay the compliance date from September 1, 2027 to September 1, 2030 for vehicles with a Gross Vehicle Weight Rating (GVWR) of greater than 4,536 kg.
