Pursuant to a statutory mandate in the Infrastructure Investment and Jobs Act, this notice will seek comments on a revised proposal to require and/or standardize equipment performance for automatic emergency braking on heavy trucks and motor carrier maintenance requirements for vehicles equipped with such technology. For several years, NHTSA has researched forward collision avoidance and mitigation technology on heavy vehicles, including forward collision warning and automatic emergency braking systems. This rulemaking proposes test procedures for measuring performance of these systems. This is a joint rulemaking of the National Highway Traffic Safety Administration (NHTSA) (RIN 2127-AM36) and Federal Motor Carrier Safety Administration (FMCSA) (RIN 2126-AC49).
