An artificial "vroom" will be fitted to electric vehicles under plans to make them safer for pedestrians, cyclists and the visually impaired.
The European Commission plans to make manufacturers install Acoustic Vehicle Alerting Systems (AVAS) on all new vehicles amid concerns they pose a risk to vulnerable road users.
This is because the cars are effectively silent, particularly at low speeds, and people cannot hear them.
While there are no recorded incidents of EVs in serious collisions, there are concerns they could pose a significant hazard.
