Why Night Driving Is More Dangerous
Even though only 25 percent of driving happens at night, nearly 50 percent of fatal crashes occur after dark. Reduced visibility, glare from oncoming headlights, and driver fatigue all contribute to increased risk.
Headlight Rules
Turn on your headlights 30 minutes before sunset and keep them on until 30 minutes after sunrise. Most states also require headlights when visibility is reduced to 500 to 1000 feet, during rain, fog, or snow, and when driving through construction zones.
High Beams vs Low Beams
Use high beams on dark rural roads when no other vehicles are nearby. Switch to low beams when an oncoming vehicle is within 500 feet or when following another vehicle within 200 to 300 feet. Never use high beams in fog because the light reflects off the fog and reduces visibility.
Dealing with Glare
If oncoming headlights are blinding you, look toward the right edge of your lane instead of directly at the lights. Slow down if necessary. Keep your windshield clean, as dirt and smudges increase glare.
Reducing Fatigue
Drowsy driving is a major danger at night. Take breaks every 2 hours on long drives. If you feel sleepy, pull over and rest. Opening a window or turning up the radio are temporary fixes that do not replace actual rest.
Tips for New Drivers
Start by driving on well-lit roads you are familiar with. Gradually build up to driving on darker, less familiar roads. Reduce your speed at night because your stopping distance must fit within your headlight range. Always be alert for pedestrians and animals, which are harder to see at night.
