The Federal Motor Carrier Safety Administration (FMCSA) has issued an Advance Notice of Proposed Rulemaking (ANPRM) proposing that motor carriers operating commercial motor vehicles in interstate commerce with a gross vehicle weight rating (GVWR) or gross vehicle weight (GVW) of 11,794 kilograms or more (26,001 pounds or more), whichever is greater, that are equipped with an electronic engine control unit (ECU) capable of governing the maximum speed be required to limit the commercial motor vehicle to a speed to be determined by the rulemaking and to maintain that ECU setting for the service life of the vehicle. This ANPRM follows a jointly issued National Highway Traffic Safety Administration (NHTSA) and FMCSA Notice of Proposed Rulemaking (NPRM) on September 7, 2016. FMCSA is requesting comments on this ANPRM no later than June 3, 2022.
