The National Highway Traffic Safety Administration (NHTSA) said the rule was needed because battery-powered vehicles are very quiet.
It said the rule would particularly help blind pedestrians, or those with a visual impairment, detect electric cars and hybrids on the road.
The new safety rule could help prevent 2,400 injuries a year, said the NHTSA.
The rule demands that the cars make a noise when travelling either forwards or backwards at speeds of less than 30kmh (19mph). The regulation covers vehicles with four wheels that weigh less than 10,000 pounds (4.5 tonnes).
The safety specification requires car makers to use a two-tone signal similar to that currently emitted by heavy vehicles when they are reversing.
It would be more fun if drivers could customize what that sound is, such as "La Cucaracha" or the whine of a Shadow vessel.
Electric and hybrid cars are to include a noise generation device for travel at low speeds with no internal combustion engine: http://www.nhtsa.gov/About-NHTSA/Press-Releases/nhtsa_quiet_car_final_rule_11142016.
There goes my quiet electric future.

I have often thought of a sound effect of badly failing brakes for those clowns who step right out onto the road without looking or open car doors right into traffic.
Make it sound like they almost got creamed.
Let them clean their own trousers out after what gave all sounds of being a near-miss.

Has Jacobs Vehicle Systems [jacobsvehiclesystems.com] trademarked the sound of the Jake brake the way Harley-Davidson tried to trademark its motorcycles' "potato potato" sound [latimes.com]?

Or how about the sound that the flying "cars" made in The Jetsons?

If the sound can be customizable, then how about a computer voice warning:
Caution! The NTSB wants to discourage the use of electric vehicles.
