When is a driver of a motor vehicle required to dip the vehicle’s lights?

1. Correct answer: When driving behind another vehicle and his high beam hits the rear part of the vehicle in front.
2. When the vehicle’s “fog light” is also turned-on.
3. Only while driving inside a tunnel.
4. When driving behind another vehicle and his “fog light” and “high beam” are turned-on at the same time.

WhySwitch to low beam when you drive behind a vehicle and your high beam lights it from behind. It dazzles the driver through the mirrors.
