The U.S. Department of Transportation’s National Highway Traffic Safety Administration (NHTSA) is adding a sound requirement for all newly manufactured hybrid and electric vehicles to help protect pedestrians.
The new federal safety standard will help pedestrians who are blind, have low vision, and other pedestrians detect the presence, direction and location of these vehicles when they are traveling at low speeds, which will help prevent about 2,400 pedestrian injuries each year once all hybrids in the fleet are properly equipped.
Under the new rule, all hybrid and electric light vehicles with four wheels and a gross vehicle weight rating of 10,000 pounds or less will be required to make audible noise when traveling in reverse or forward at speeds up to 30 kilometers per hour (about 19 miles per hour). At higher speeds, the sound alert is not required because other factors, such as tire and wind noise, provide adequate audible warning to pedestrians.
Manufacturers have until Sept. 1, 2019, to equip all new hybrid and electric vehicles with sounds that meet the new federal safety standard. Half of new hybrid and electric vehicles must be in compliance one year before the final deadline.
The new standard, Federal Motor Vehicle Safety Standard No. 141, responds to Congress’ mandate in the Pedestrian Safety Enhancement Act that hybrid and electric vehicles meet minimum sound requirements to provide an audible alert for blind and visually-impaired pedestrians.
