At night you see less, glare can blind you, and objects appear late. Use your headlights correctly, never outdrive them, and stay alert for fatigue and wrong-way drivers — who are usually impaired.

Know the rule

Turn on your headlights — not parking lights — as soon as light begins to fade in the late afternoon.

Handbook p. 57 ↗

Know the rule

You must use headlights from sunset to sunrise. Never drive so fast that you can't stop within the distance your lights show.

Following within 200 ftLow beams
Handbook p. 57 ↗

Know the rule

If an oncoming driver doesn't dim their high beams, don't look at the lights. Glance toward the right side of the road, then look ahead to track the other vehicle until you've passed.

Highway hypnosis

Also called "white line fever": a trance-like state that can occur during a long period of highway driving.

Handbook p. 58 ↗

Know the rule

Whenever you get tired, pull over and rest. Use the radio and fresh air, and stop every hour to walk and exercise.

Handbook p. 58 ↗

If you see a wrong-way driver on a divided highway:

  • Slow down by easing your foot off the gas
  • Make sure no vehicle is beside you, then steer away from the wrong-way driver
  • Get to a safe place, call 911 and report it
  • If overhead boards show a wrong-way driver ALERT, move toward the nearest exit as soon as safely possible
Handbook p. 58 ↗

Know the rule

Wrong-way drivers are usually in the left or HOV lane but enter from the right via off-ramps. Most wrong-way crashes are caused by impaired drivers.

Handbook p. 58 ↗

Know the rule

Don't tailgate, so you can react if the car ahead suddenly swerves. Never drive distracted or impaired, and have a plan so you won't waste a moment.

Handbook p. 59 ↗

Put it into practice

At night on the Loop 101 you see headlights coming at you in the left lane. Ease off the gas, check that the lane to your right is clear, move away, then get somewhere safe and call 911.

On a highway, when may you use your high-beam headlights?
  1. When no oncoming car is within 200 feet
  2. When no oncoming car is within 1,000 feet
  3. When no oncoming car is within 500 feet
  4. Only within city limits

Answer: When no oncoming car is within 500 feet

Use high beams on highways when no oncoming vehicle is within 500 feet; switch to low beams as vehicles approach.

Handbook p. 57 ↗
When following another vehicle at night, at what distance should you switch to low-beam headlights?
  1. Within 1,000 feet
  2. Within 200 feet
  3. Within 500 feet
  4. Within 50 feet

Answer: Within 200 feet

Use low beams whenever you are within 200 feet of the vehicle you're following, to avoid blinding the driver ahead.

Handbook p. 57 ↗
If an oncoming car's high beams are not dimmed, what should you do?
  1. Look toward the right edge of the road
  2. Stare directly at the headlights to judge distance
  3. Flash your own high beams repeatedly at them
  4. Speed up to pass the glare quickly

Answer: Look toward the right edge of the road

Avoid looking directly at bright oncoming lights; glance toward the right side of the road instead, then look ahead again.

Handbook p. 57 ↗
What is 'highway hypnosis' or 'white line fever'?
  1. Temporary blindness from headlights
