Your lights help you see and be seen, and your horn warns others. Night driving is more dangerous than daytime driving because vehicles, pedestrians and obstacles are harder to see, so it has its own rules.

Use your horn to:

  • Warn pedestrians or other drivers of possible trouble
  • Avoid crashes
Handbook p. 53 ↗

Don't use your horn to:

  • Show anger or complain about other drivers' mistakes
  • Try to get a slower driver to move faster
  • Try to get other vehicles moving in a traffic jam
Handbook p. 53 ↗

You must use headlights and taillights:

  • From one-half hour after sunset until one-half hour before sunrise
  • When you can't clearly see people or vehicles 500 feet ahead
  • Whenever you use your windshield wipers (daytime running lights aren't sufficient)
  • In rain, snow, fog, or other weather that makes it hard to see
  • Anytime you have trouble seeing other vehicles
  • To alert another driver to turn on their headlights
  • While driving through a tunnel
Handbook p. 53 ↗

Know the rule

When your vehicle breaks down, use your emergency lights, move as far to the side of the road as you can, and stay off the road. Never change a flat tire in a traffic lane. Emergency lights can also warn drivers behind you of a crash or hazard.

Know the rule

Use high beams only in dark areas where you can't see the road surface ahead. If an oncoming driver keeps high beams on after you flick your lights, stay to the right and do not turn on your high beams.

Handbook p. 54 ↗

When driving at night:

  • Don't drive when you are tired or drowsy
  • Drive more slowly, especially in unfamiliar areas, so you can stop within the distance you can see
  • Keep more space around you, and extra near trucks and heavy equipment
  • Put the inside mirror in the "night" position and keep inside lights off
  • Don't look straight at headlights: look to the lower right side of your lane
  • Keep your windows and headlights clean
Handbook p. 54 ↗

Know the rule

If another driver flashes headlights at you, your headlights may be off or your high beams may be on.

Handbook p. 54 ↗

Put it into practice

On a dark rural road with high beams on, you see taillights ahead. Switch to low beams once you're within 200 feet of that vehicle. For an oncoming car, you'd switch at 500 feet.
