Licensed operators Dott, Lime and Tier are working with UK engineers amid concerns from charities for blind people
E-scooters could all be given the same distinctive artificial sound to warn people when they are approaching, after engineers and rival operators announced a joint research project to identify the best noise for them to make.
Acoustic researchers will work with firms licensed to run UK e-scooter rental schemes with the aim of developing a universal sound for the otherwise near-silent vehicles. The sound would help alert other road users, particularly people with sight loss.
