On a dark road with high beam headlights on, how close should you allow an oncoming vehicle to get before you dip your beam?

• A. 100 m
• B. 500 m
• C. 1000 m
• D. 300 m

Answer: (D)

When driving at night with high beams, you switch to low beams as you approach an oncoming vehicle to avoid blinding them and to keep both drivers safe. The standard distance to dip is within about 300 meters of the oncoming vehicle. This gives the other driver enough time to see your dimmed lights and react, while still letting you see the road ahead clearly. If you dip earlier than necessary, you blunt your own night vision for no real gain; if you wait until they’re much closer, their eyes can be blinded by your glare. So, dip when you’re within 300 meters of the oncoming vehicle.
