When riding at night behind a vehicle with high beams, what distance should you maintain before dipping your own headlights?

• A. 50 m
• B. 150 m
• C. 250 m
• D. 350 m

Answer: (B)

When you’re behind another vehicle at night, your high beams can blind or dazzle the driver in front. The rule is to switch to low beams once you’re close enough that your headlights would shine directly into their eyes or into their mirrors. This creates a safer amount of light for both of you, giving the driver ahead a clearer view of the road and allowing you to react to any hazards without causing glare. If you dip too early, you lose visibility; if you wait too long, you risk blinding the other driver. So you dip as you close in to the point where your glare would affect the driver in front.
