Such rule is going to be imposed on each electric and hybrid vehicle sold in US according to the issue of NTHSA. Both all-electric and hybrid cars are required to have sound-emitting devices onboard in order to gain attention of pedestrians and cyclists starting from September 2019. NTHSA claimed the risk of accident involving pedestrians and EVs to be 19% higher than of cars with internal combustion engines since they produce sounds loud enough for people to detect. Moreover, the officials estimate such rule to decrease a number of pedestians injuries by 2,400 in a year.
