(KGTV) - Are police in India really testing traffic lights that stay red if too many drivers honk their horns?
Yes.
Noise pollution from people laying on their horns is a big problem in India.
So late last year, Mumbai police set up noise meters on traffic light poles. If the meters registered 85 decibels or more, the lights were reset and stayed red longer.
Another trial at ten more locations is planned for March.
Mumbai is ranked as the world's 4th most congested city.
