Law to require HEVs and EVs to make noise by 2020

A new rule in the United States will require all hybrid and electric vehicles to emit a noise when operating below 18.6mph. The purpose of the noise is to warn pedestrians (and animals) of the otherwise-quiet vehicle’s approach. The rule was initially proposed in 2010, but has faced delays for the last eight years.

Automakers must have fifty percent of applicable models in compliance by September 2019. Hybrid Cars has the story. Read more.
