Cars That Make Too Little Noise? Canada Proposes Measures to Make EVs Louder

Since the advent of generally-available electric-powered vehicles, one question that has bubbled up periodically is the potential danger to pedestrians posed by the relative quiet with which EVs circulate on the road, particularly in comparison with the much louder combustion-engine vehicles we’ve been used to hearing for the past several decades.

Late last Friday, just as many were shutting their laptops for the weekend, the Government of Canada announced it will propose amendments to federal Motor Vehicle Safety Regulations to require that all hybrid and electric vehicles produce a minimum level of noise.

According to the Ministry of Transport’s statement, “Research shows (hybrid and electric vehicles’) lack of sound poses an increased risk of collision to road users such as visually impaired Canadians, cyclists, and pedestrians.” The proposal came to be after a series of consultations with and submissions from different stakeholders.

From voluntary to mandatory
Several automakers already place sound emitters in their hybrid and electric-powered vehicles to help alert others on the road to their presence. The new initiative by the federal government would seek to make the presence of an Acoustic Vehicle Alert System mandatory in new hybrid and electric vehicles.

Particularly, these emitters would produce sound from the vehicle at low speeds, in other words in urban settings with more pedestrians and cyclists around. The volume and pitch from these sound emitters will vary depending on vehicle speed to allow road users to hear if a vehicle is speeding up or slowing down.
