At night you can see only as far as your headlights reach, and it's harder to judge how far away other vehicles are and how fast they're moving. Fog shrinks that view even more.

Know the rule

Night driving is more risky and difficult than daytime driving: it's harder to judge the distance and speed of other vehicles.

Handbook p. 27 ↗

At night:

  • Use your headlights and follow the high-beam rules
  • Don't stare into oncoming headlights; look ahead or slightly right, at your lane's edge or the road edge
  • Increase the distance between you and the vehicle ahead
Handbook p. 28 ↗

Driving in fog:

  • Reduce your normal driving speed
  • When you see headlights or another vehicle's taillights ahead, slow even more and be ready to stop quickly
  • Use low beam headlights only, plus fog lights if you have them
Handbook p. 28 ↗

Know the rule

If fog is so thick you cannot safely drive, pull completely off the road to a safe location and turn on your emergency flashers.

Know the rule

At night you can see only as far as your headlights allow, which makes it hard to see where you are going and what other drivers are doing.

Handbook p. 27 ↗

Put it into practice

Fog thickens until you can barely see the lane lines. Don't stop in the travel lane; pull completely off the road to a safe place and turn on your emergency flashers until it clears.

Put it into practice

An oncoming truck's headlights are blinding you. Shift your eyes to the right edge of your lane and keep steering by it until the truck passes.

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.

Instead of staring into the headlights of oncoming traffic at night, where should you look?
  1. At the center line to your left
  2. At the road ahead or your lane's right edge
  3. At the oncoming vehicle's headlights
  4. At your rear-view mirror

Answer: At the road ahead or your lane's right edge

Instead of staring into oncoming headlights, look at the road ahead or slightly toward the right edge of your lane.

Handbook p. 28 ↗
If fog becomes too thick to safely drive, what should you do?
  1. Turn on your high beams and continue slowly
  2. Stop in your travel lane with headlights on
  3. Pull off the road; use flashers
  4. Speed up to get through the fog quickly

Answer: Pull off the road; use flashers

If fog is too thick to drive safely, pull completely off the road to a safe location and turn on your emergency flashers.

Handbook p. 28 ↗
Which headlight beam should you use when driving in fog?
  1. High beams only
  2. No headlights at all
  3. Alternating high and low beams
  4. Low beams, plus fog lights

Answer: Low beams, plus fog lights

In fog, use low beam headlights only, along with fog lights if your vehicle has them.

Handbook p. 28 ↗
Driving at night is generally more risky than daytime driving because it is harder to judge distance and speed.
  1. True
  2. False

Answer: True

Night driving is riskier because you cannot see as well and it's harder to judge distance and speed of other vehicles.

Handbook p. 27 ↗
At night, you should decrease the following distance between you and the vehicle ahead.
  1. True
  2. False

Answer: False

You should increase the distance between you and the vehicle ahead at night to allow more time to react.
