Federal Motor Vehicle Safety Standard No. 141, Minimum Sound Requirements for Hybrid and Electric Vehicles

Riepilogo

This document responds to petitions for reconsideration regarding NHTSA's December 2016 final rule which established new Federal motor vehicle safety standard (FMVSS) No. 141, "Minimum sound for hybrid and electric vehicles." The agency received submissions from three petitioners requesting six discrete changes to the final rule, and also received technical questions from the petitioners. After consideration of the petitions and all supporting information, NHTSA has decided to grant the petitions for four of the discrete changes, deny one, and request comment in a separate document for the sixth proposed change.
