The U.S. Department of Transportation (DOT) has extended the effective date of a final rule requiring electric and hybrid vehicle manufacturers to install sound-emitting technologies, to reduce the risk of pedestrian crashes. The rule requires hybrid and electric vehicles to emit sound while stationary with the vehicle propulsion system activated, and to emit minimum sound levels while in reverse, and while the vehicle is in forward motion up to 30 km/h. The effective date delay is based on the President’s Jan. 20, 2017, “Regulatory Freeze Pending Review” memorandum, as well as allowing additional time to respond to several petitions for reconsideration filed in response to the final rule.
