Drivers must dim their high beam headlights when within _____ of an oncoming vehicle.

500 feet
100 feet
200 feet
250 feet
Explanation

The headlights of your vehicle are an important safety feature, especially at night. It is important that you use them properly. When you come within 500 feet of an oncoming vehicle, you must dim your high beam headlights to prevent blinding the other driver. This will allow them to have enough visibility to stay on course and will also allow you to see the road ahead more clearly. It is also important to switch to low beams when following a vehicle at a distance of 300 feet or less.
