The Code of Virginia requiresThe Code of Virginia requires that you use your headlights from sunset to sunrise and during bad weather, such as rain, fog, snow, or when you use your windshield wipers.

The posted speed limits are calculated for daylight driving and are often too fast for nighttime conditions.

Dirty headlights and improper headlight alignment will add to this traffic safety problem.
