Trucks don't drive like cars. They're bigger and heavier, they need more room and time, and their drivers can't see large areas around them. Many car-truck crashes could be avoided if drivers knew these limits.

250,000+

Crashes each year involving passenger vehicles and large trucks

More than 70%

Share of fatal car-truck crashes caused by the driver of the other vehicle, not the truck driver

Handbook p. 44 ↗
4 out of 5

In fatal crashes involving trucks, the driver of the other vehicle was killed

Handbook p. 44 ↗

Know the rule

Most car-truck crashes happen in daylight, on straight, dry pavement in good weather.

Handbook p. 44 ↗

The bigger the truck:

  • The bigger the driver's blind spots
  • The more room the truck needs to maneuver
  • The longer it takes the truck to stop
  • The longer it takes you to pass it
Handbook p. 44 ↗

No-Zones

A truck's blind spots, around its front, back and sides. If you can't see the truck's side mirrors, the driver can't see you.

Handbook p. 44 ↗
Truck no-zones (blind spots)
Truck No-Zones: front, rear and both sides

Know the rule

Passing a truck takes longer. Keep a consistent speed, and don't return to the lane until you can see the truck's cab in your inside rearview mirror.

Handbook p. 44 ↗

Know the rule

Never go around a truck that is backing up or getting ready to. Its trailer can hide you completely.

Handbook p. 44 ↗

Know the rule

Trucks have long blind spots directly behind them. Following too closely greatly raises your risk of a rear-end crash and cuts your view of traffic.

Handbook p. 45 ↗

Know the rule

Trucks have much larger side blind spots than cars. Don't linger there. If the driver must change lanes quickly, you could be hit.

Handbook p. 45 ↗

Know the rule

Truck drivers often swing wide to the left to make a right turn. Don't cut in between the truck and the curb or shoulder.

Handbook p. 45 ↗

Put it into practice

A tractor-trailer ahead signals right but drifts left first. Don't take the gap on its right. It's swinging wide for the turn and could close on you. Stay back until it completes the turn.

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.

If you can't see a truck's side mirrors, what does that mean?
  1. The truck driver can't see you
  2. The truck's mirrors are broken
  3. You are following too closely, but visible
  4. Nothing significant

Answer: The truck driver can't see you

If you can't see the truck's side rearview mirrors, then the truck driver can't see you either.

Handbook p. 44 ↗
What should you never do when a truck is backing up or preparing to back up?
  1. Wait for it to finish
  2. Go around the truck
  3. Stop your vehicle
  4. Watch for its backup lights

Answer: Go around the truck

Never go around a truck that is preparing to back up or is in the process of backing up.

Handbook p. 44 ↗
Why do trucks often swing wide to the left before making a right turn?
  1. To get a better view of traffic
  2. It's a habit, not a necessity
  3. They need more room to maneuver
  4. To give cyclists room to pass

Answer: They need more room to maneuver

The bigger the truck, the more room it needs to maneuver, so drivers often swing wide left to make a right turn.

Handbook p. 45 ↗
About what percentage of fatal crashes between cars and large trucks were caused by the other vehicle's driver, not the trucker?
  1. About 25%
  2. About 50%
  3. Less than 10%
  4. More than 70%

Answer: More than 70%

In more than 70% of fatal crashes involving cars and trucks, the other driver, not the trucker, caused the crash.

Handbook p. 44 ↗
In four out of five fatal crashes involving trucks, who is most likely to be killed?
  1. The driver of the other vehicle
  2. The truck driver
  3. A pedestrian nearby
  4. A passenger in the truck

Answer: The driver of the other vehicle

In four out of five fatal truck crashes, it's the other vehicle's driver who is killed.

Handbook p. 44 ↗
It's safe to cut between a truck and the curb right after it signals a right turn.
  1. True
  2. False

Answer: False

Never cut between a turning truck and the curb or shoulder; it increases crash risk.
