Its something manufacturers are already looking into and we understand from previous tests that the main risk is lower-speed driving such as reversing when manoeuvring around a car park when the car is most quiet, said Sally Longford, who is in charge of neighbourhood services and local transport at Nottingham city council.Photograph: Scott BarbourGetty Images Jamie Doward Sun 6 May 2018 09.00 BST Last modified on Wed 23 Sep 2020 15.42 BST They are green, clean and make very little noise.It is this latter quality, initially seen by many as a good thing, that has become an acute concern for safety campaigners, who fear that the rising number of electric vehicles constitutes a silent menace.When they travel at under 20kph (12 mph) the vehicles can barely be heard, especially by cyclists or pedestrians listening to music through headphones.
The greatest risks associated with electric vehicles are when they are travelling at low speeds, such as in urban areas with lower limits, as the noise from tyres and the road surface, and aerodynamic noise, are minimal at those speeds, said Kevin Clinton, from the Royal Society for the Prevention of Accidents. From July next year, all new electric and hybrid models seeking approval in Europe will have to emit a noise when travelling at low speeds. Existing vehicles are expected gradually to be retrofitted with devices. James White, at the Guide Dogs for the Blind Association, is worried about the risk the cars pose to people with sight loss. He said that for people who struggle to see them, the vehicles should indicate their presence in other ways. Research shows electric cars are about 40 more likely to hit a pedestrian than a conventional vehicle. One study suggests that 93 of blind and partially sighted people have had problems with them. Guide dogs are all about giving people confidence and independence and a near miss or an incident with a vehicle of this type could really set people back a long way. Kesalahan Bounce Pass Driver Had UsedIn Japan there was a national outcry when a guide dog and its owner were killed by a reversing non-electric vehicle whose driver had used a pause control to deactivate its sound emitter. The new standards, which in Europe will be introduced via an EU directive, will require activation by default when the vehicle is on. About 140,000 electric vehicles are now registered in Britain compared with just 3,500 in 2013. By 2030 the National Grid predicts there could be as many as 9 million electric vehicles on Britains roads. Surprise UK rise in new car sales but diesel continues to plunge Read more Battles have raged over what sort of sound the vehicles should emit and when they should emit it, Hanson-Abbott said. The agreed standard is a mix of tonal sounds and white noise that will cut out once the vehicle gets to about 20kph and the sound of the tyres becomes sufficiently audible. One is that its very pleasant on the ear and the second is that the source direction of that sound is instantly recognisable. The moment you hear white sound you can point directly at where its coming from. ![]() Its a huge improvement on the noise emitted by petrol or diesel vehicles because its sound source is directional, Hanson-Abbott said. Politicians promoting electric cars as the future of urban transportation have welcomed the move to make the vehicles noisier.
