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.

The "backing up" noise from heavy machinery? Ew.
Hey Einsteins: How about you, oh I don't know, record normal gasoline engines and play that instead?

Imagine! It could replay an engine noise, but using the right volume for the zone, and even time of the day. All those computers in cars sure can do it.
No idea why people is so obsessed with beeps for something that would be normal rolling. Even beeps aren't the best for backing vehicles anyway, there are white noise buzzers that work better.
