WASHINGTON: The US government on Monday finalised long-delayed rules that will require “quiet cars” like electric vehicles and hybrids to emit alert sounds at speeds of up to 18.6 miles per hour (30km per hour) to help prevent injuries among pedestrians, cyclists and the blind.
The rules, which were required by Congress, will require automakers like Tesla Motors Inc, Nissan Motor Co and Toyota Motor Corp to add alert sounds to all vehicles by September 2019.
The US Transportation Department said it expects the rules would prevent 2,400 injuries a year in 2020 and would require the addition of alert sounds to about 530,000 2020 model vehicles.
The US National Highway Transportation Department said the rules will cost the auto industry about US$39mil annually because automakers will need to add an external waterproof speaker to comply. But the benefits of the reduced injuries are estimated at US$250mil to US$320mil annually.
NHTSA estimates the odds of a hybrid vehicle being involved in a pedestrian crash are 19% higher compared with a traditional gas-powered vehicle. About 125,000 pedestrians and bicyclists are injured annually.
The rules will also help the blind and visually impaired.
“This is a common-sense tool to help pedestrians-especially folks who are blind or have low vision-make their way safely,” said NHTSA Administrator Dr Mark Rosekind in a statement.
The new rules apply to hybrid and electric cars, SUVs, trucks and buses that are up to 10,000 pounds and are aimed at preventing crashes at intersections or when electric vehicles are backing up.
NHTSA originally proposed extending the audio sound requirements to all vehicles on the road including motorcycles and larger trucks and buses.
At higher speeds, the sound alert is not required because other factors like tire and wind noise provide adequate warning to pedestrians, NHTSA said.
Advocates for the blind have pushed for the rules and praised the announcement.
Automakers previously raised concerns about the alerts, saying they are too loud and too complicated. They also want them required only at lower speeds.
Under a 2010 law passed by Congress, NHTSA was supposed to finalise the regulations by January 2014, but the rules were subjected to a lengthy White House review.
The Trump administration could opt to review the rules once it takes office. - Reuters
