When must you dim your high beam headlights when an approaching car is coming?

You must dim your high beam headlights when an approaching car is within 150 metres. This distance is important to ensure that you do not blind the oncoming driver with your bright lights, which can significantly impair their ability to see the road and any potential hazards. The law mandates this action as part of safe driving practices, helping to maintain visibility for all road users.

Being respectful to other drivers by dimming your headlights contributes to safer driving conditions at night. It allows the approaching vehicle to see the road clearly and helps prevent accidents caused by reduced visibility. This regulation is designed to balance the need for adequate illumination on your part while promoting overall road safety.
