The U.S. is considering an automakers petition to allow drivers to choose the warning tone their electric vehicles make.
Congress ordered in 2010 that EVs emit a warning tone for pedestrians when traveling at speeds below about 19 mph (30 kph).
The standard, which wasn’t finalized until last year, requires that carmakers equip at least half the EVs they sell in the U.S. with sound alerts, beginning this month. All new EVs must have such systems by next September.
NHTSA estimates that fitting cars with the waterproof speakers needed to emit the warning sound will cost carmakers $40 million per year. The technology is expected to prevent 2,400 injuries per year.
