The new regulation is designed to allow those who are visually impaired to hear vehicles more easily.
“The government understands the concerns of the visually impaired about the possible hazards posed by quiet electric vehicles,” Roads Minister Michael Ellis said. “This new requirement will give pedestrians added confidence when crossing the road.”
The regulation will apply to all new types of ‘quiet’ electric and hybrid vehicles from 1 July 2019, and to all new quiet electric and hybrid vehicles registered from July 2021.
