There's less traffic at night, yet nearly half of all fatal crashes in Minnesota happen after dark. Good headlight habits, glare control and watching for deer make the difference.

Before a night trip

  • Study maps and directions before starting out
  • Make sure your vehicle lights work
  • Make sure your windshield is clean and free of defects

Know the rule

You should be able to stop within the distance your headlights light up. For most vehicles that's no more than 350 feet on high beam.

Handbook p. 76 ↗

Know the rule

If oncoming headlights blind you, use the white line along the road's edge as a guide. For glare from behind, use a day-night mirror or adjust your regular mirror.

Handbook p. 76 ↗

Know the rule

Deer are most active from dusk to dawn. At night, scan the roadsides for your headlights reflecting in their eyes; if you see that, slow down, blow the horn and be ready to stop. Watch for more than one — deer may cross anywhere, anytime, even in towns.

If your headlights suddenly go out

  • Try parking lights, hazard lights or turn signals — one may light your way off the road
  • On a busy or lighted road, you'll likely have enough light to guide you
  • On a dark, deserted road, slow down and stay on the pavement until you can pull onto the shoulder
Handbook p. 89 ↗

Put it into practice

You're using high beams on a dark highway. An oncoming car appears: dim to low beams by the time it's within 1,000 feet. Later you catch up to a car ahead — dim before you're within 200 feet of it.

Check your understanding

Read the question, decide on an answer, then open it to check the explanation. These are Roadwise study questions based on the source handbook.

About what share of fatal traffic crashes in Minnesota occur after dark?
  1. Nearly half
  2. About one in ten
  3. About one-quarter
  4. About three-quarters

Answer: Nearly half

Nearly half of all fatal crashes in Minnesota happen after dark, despite less traffic at night.

When following another vehicle at a distance of 200 feet or less at night, your headlights must be on:
  1. High beam
  2. Low beam
  3. Parking lights only
  4. Fog lights only

Answer: Low beam

Following within 200 feet requires low beam headlights to avoid blinding the driver ahead.

Handbook p. 76 ↗
When within 1,000 feet of an oncoming vehicle at night, your headlights must be on:
  1. High beam
  2. Fog lights only
  3. Low beam
  4. Parking lights only

Answer: Low beam

You must dim to low beam within 1,000 feet of an oncoming vehicle to avoid blinding the driver.

Handbook p. 76 ↗
You should be able to stop within the distance your headlights light up. For most vehicles on high beam, that distance is:
  1. No more than 500 feet
  2. No more than 1,000 feet
  3. No more than 200 feet
  4. No more than 350 feet

Answer: No more than 350 feet

Most vehicles' high beams illuminate up to about 350 feet.

Handbook p. 76 ↗
If you are blinded by glare from oncoming headlights, what reference should you use to stay in your lane?
  1. The white line along the edge of the road
  2. The yellow center line
  3. The taillights of the car ahead
  4. The oncoming car's headlights

Answer: The white line along the edge of the road

Using the white edge line as a visual reference helps you stay in your lane when blinded by glare.

Handbook p. 76 ↗
Deer are most active, and most likely to be hit, during what time of day?
  1. From late morning to midday
  2. Mostly in the early afternoon
  3. From dusk to dawn
  4. Deer activity doesn't vary by time

Answer: From dusk to dawn

Deer are most active from dusk to dawn, making those hours higher risk.
