- This NPRM (National Highway Traffic Safety Administration) proposes to adopt a new Federal Motor Vehicle Safety Standard (FMVSS) to require automatic emergency braking (AEB) systems on heavy vehicles, i.e., vehicles with a gross vehicle weight rating greater than 4,536 kilograms (10,000 pounds). An AEB system uses multiple sensor technologies and sub-systems that work together to sense when the vehicle is in a crash imminent situation and automatically applies the vehicle brakes if the driver has not done so or automatically applies more braking force to supplement the driver’s applied braking. FMCSA proposes that vehicles currently subject to FMVSS No. 136 would be required to comply with FMCSA’s proposed ESC regulation on the final rule’s effective date. Vehicles with a GVWR greater than 4,536 kilograms (10,000 pounds) not currently subject to FMVSS No. 136 would be required to meet the proposed ESC regulation on or after the first September 1 that is five years after the date of publication of the final rule.
