You need time and space to react. Michigan's rules of thumb are measured in seconds for following and in feet for headlight use, and night driving shrinks what you can see.

Stopping distance depends on:

  • Fatigue and how well you pay attention
  • The type and weight of your vehicle
  • The condition of your tires and brakes
  • The road surface and the weather

3–4 seconds

Required following distance on dry or wet pavement; increase up to 6 seconds or more at higher speed or in bad conditions

Handbook p. 78 ↗

Know the rule

To check it, when the vehicle ahead passes a sign or other fixed point, count "one-thousand one, one-thousand two, one-thousand three." If you reach the point before finishing three seconds, you're too close.

Handbook p. 78 ↗

Know the rule

Wet pavement needs more time and space. For a smooth stop, press the brake gradually harder, then ease off just before you stop.

20–30 seconds

How far down the road to look ahead to spot hazards early

Handbook p. 78 ↗

Know the rule

Headlights must be on from one half-hour after sunset to one half-hour before sunrise, and whenever visibility is reduced. Use low beams in daytime fog, rain or snow.

Handbook p. 78 ↗
500 ft

Headlights required whenever you can't clearly see people and vehicles at this distance

Handbook p. 78 ↗

Know the rule

It is illegal to use only parking lights when headlights are required.

Handbook p. 78 ↗
500 ft

Don't use or even flash high beams within this distance of an oncoming vehicle

Handbook p. 78 ↗

Know the rule

Dim your lights for pedestrians and cyclists too, and don't use high beams behind other vehicles.

Handbook p. 78 ↗

Know the rule

At night, drive within the range of your headlights — you must be able to stop within the distance you can see.

Handbook p. 78 ↗

Know the rule

If oncoming drivers don't dim, look at the right edge of the road ahead, not into their lights; glare can blind you for several seconds. A dirty windshield makes glare worse.

Handbook p. 78 ↗

Put it into practice

On a dark rural road with high beams on, you see headlights approaching about a quarter mile away. Switch to low beams before the car is within 500 feet — about a football field and two-thirds.

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.

When must headlights be turned on, in relation to sunset and sunrise?
  1. From sunset to sunrise only
  2. From 1 hour after sunset to 1 hour before sunrise
  3. From 1/2 hour after sunset to 1/2 hour before sunrise
  4. Only once it's fully dark

Answer: From 1/2 hour after sunset to 1/2 hour before sunrise

Headlights must be on from one half-hour after sunset until one half-hour before sunrise, and anytime visibility is reduced.

Handbook p. 78 ↗
At what distance must you be able to see people and vehicles clearly, or headlights are required?
  1. 100 feet
  2. 1,000 feet
  3. 500 feet
  4. 300 feet

Answer: 500 feet

Headlights must be on any time there isn't enough daylight to see people and vehicles clearly at 500 feet.

Handbook p. 78 ↗
Within what distance of an oncoming vehicle is it illegal to use or flash your high beams?
  1. 1,000 feet
  2. 300 feet
  3. 100 feet
  4. 500 feet

Answer: 500 feet

It's illegal to use or flash high beams within 500 feet of an oncoming vehicle.

Handbook p. 78 ↗
If an oncoming driver doesn't dim their headlights, where should you look?
  1. At the right edge of the road ahead
  2. At the center of the road
  3. At the left edge of the road
  4. Directly at their headlights

Answer: At the right edge of the road ahead

If oncoming headlights aren't dimmed, keep your eyes on the right edge of the road rather than looking directly at the lights.

Handbook p. 78 ↗
Traffic is moving normally in clear, dry conditions. How many seconds of following distance are generally recommended?
  1. 6-8 seconds
  2. 10+ seconds
  3. 1-2 seconds
  4. 3-4 seconds

Answer: 3-4 seconds

A 3- to 4-second following distance is generally required under normal conditions.

Handbook p. 78 ↗
What does the "look ahead" rule for defensive driving recommend?
  1. Look 5-10 seconds ahead
  2. Look 20-30 seconds ahead
  3. Look 3-4 seconds ahead
  4. Look 45-60 seconds ahead

Answer: Look 20-30 seconds ahead

Look down the road 20-30 seconds ahead to spot potential hazards and avoid last-second reactions.
