Are EVs too quiet to be safe?

Concern is being expressed in the UK over the safety of low noise, electric vehicles. Children and those with poor sight are particularly at risk from electric vehicles, which are much quieter in operation than conventional vehicles powered by internal combustion engines.

Electric vehicles are becoming increasingly popular in some countries but concern is being expressed over their low operating noise

Concern is being expressed in the UK over the safety of low noise, electric vehicles. Children and those with poor sight are particularly at risk from electric vehicles, which are much quieter in operation than conventional vehicles powered by internal combustion engines. Many pedestrians rely on hearing to judge if a vehicle is approaching and there is concern over the increasing proliferation of EVs in urban areas. And this factor has been encouraged in UK capital London for example by the recent introduction of the ultra-low emission zone (ULEZ).


A report produced by the by the Society of Motor Manufacturers & Traders (SMMT) revealed new registrations of electric vans rose nearly 21% in 2018. But there is concern that increasing numbers of electric vans, buses and other EVs will lead to increased deaths unless drivers utilise noise safety technology.

From July 2019, all new EV models will have to emit a noise when travelling at low speed. However this only covers new models registered after September 1 and then new registrations after September 2021.

Manufacturers must not wait until the law forces them to make noiseless hybrid and electric vehicles emit life-saving sound, according to Chris Hanson-Abbott OBE, of road safety device manufacturer Brigade Electronics.

He said: “There is no doubt the adoption of hybrid and electric vans is great news for the environment and UK air quality. But the average person struggles to hear electric and hybrid cars approach at speeds of up to 20km/h.

Research by the charity Guide Dogs for the Blind shows electric cars are about 40% more likely to hit a pedestrian than a petrol or diesel vehicle. And a study carried out in Japan has previously shown that the elderly are at risk from EVs or hybrid vehicles operating in electric mode.

Nick Simmons, CEO of Roadpeace, the national charity for road crash victims in the UK, too has expressed concern over the dangers of quiet vehicles. “Roadpeace was founded on the principle of road danger reduction and as such we are strong advocates of tackling danger at source.”

“The influx of electric and hybrid vehicles presents a new silent hazard on to our roads of which the majority of our members will not be aware therefore being a significant risk to vulnerable road users.  Added to this, the fact that the majority of these vehicles are working in urban environments further heightens the risk.”

    Electric vehicles and hybrids should be fitted with noise emission equipment to reduce danger levels for the blind and partially sighted, according to the European Blind Union (EBU). The EBU is calling on the EU to make noise generators compulsory for all electric and hybrid vehicles due to the obvious risks these pose to blind and partially sighted people. Hybrid vehicles generally run in electric mode when operating at lower speeds in the urban cycle and generate very little engine noise, while electric v

    Data from the UK reveals that quiet electric vehicles or hybrids operating in electric mode pose particular problems for pedestrians. A report has found that such vehicles are 40% more likely to be involved in a traffic incident involving a pedestrian than a conventional combustion-engined vehicle. The report adds that partially sighted or blind people face the highest risks, while children and older people are also at risk. This follows earlier research from Japan, highlighting the risks to pedestrians pos

    A new move by the US Department of Transportation’s National Highway Traffic Safety Administration (NHTSA) could see hybrid and electric vehicles being required to meet minimum sound emissions standards. This would be so as to help make pedestrians more aware of the approaching vehicles and follows on from a Japanese study into the prevalence of accidents involving hybrid vehicles with pedestrians in urban areas. “Safety is our highest priority, and this proposal will help keep everyone using our nation’s
