Emergency vehicles with sirens and lights get the road. Large trucks need far more room to turn and stop than you do, so give them space and never squeeze in beside or in front of them.

Know the rule

Police cars, ambulances, fire engines and other emergency vehicles have the right-of-way when using sirens and flashing lights.

Handbook p. 37 ↗

When you see or hear an emergency vehicle using its signals, immediately:

  • Move as close as possible to the edge of the road
  • Stay out of intersections
  • Remain stopped until the emergency vehicle has passed
Handbook p. 37 ↗

Know the rule

If you're going the same direction as an emergency vehicle using its signals, you may not pass it unless it stops or a police officer tells you to.

Handbook p. 37 ↗

Know the rule

Approaching a stopped emergency vehicle, tow truck or other service vehicle, move to a lane not immediately next to it. If you can't, slow to a safe speed and be ready to stop.

Handbook p. 37 ↗

Know the rule

Trucks make wide turns and need more space. For a right turn they often move left first, so don't assume they're changing lanes and try to pass on the right.

Truck wide right turn caution
Caution: wide right turns

Know the rule

If a truck is stopped at or approaching an intersection, never cut in along its right side as it begins to turn. You could be caught between the truck and the curb.

Handbook p. 38 ↗

Know the rule

Pass a truck quickly, and move back in only when you can see both of its headlights in your rear-view mirror.

Handbook p. 38 ↗

Know the rule

Don't stop past the stop line. Your vehicle could block trucks turning from the cross street.

Know the rule

A fully loaded truck can take the length of a football field to stop.

Put it into practice

A tractor-trailer ahead drifts left with its right signal on at an intersection. It's setting up a wide right turn. Stay behind it; don't slip into the gap on its right.

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 an emergency vehicle approaches with sirens and lights on, what must you do?
  1. Speed up to clear the intersection first
  2. Pull into the nearest intersection and wait
  3. Continue at normal speed but move slightly right
  4. Pull to the road's edge and stop

Answer: Pull to the road's edge and stop

You must move as close as possible to the edge of the road, stay out of intersections, and remain stopped until the emergency vehicle passes.

Handbook p. 37 ↗
If you're going the same direction as an emergency vehicle using its signals, when may you pass it?
  1. Only if it stops or police say so
  2. Anytime it's safe to do so
  3. Only if you are already ahead of it
  4. Never, under any circumstance

Answer: Only if it stops or police say so

You may not pass an emergency vehicle using its signals going your direction unless it stops or an officer directs you to pass.

Handbook p. 37 ↗
If you approach a stopped emergency or service vehicle on the road, what must you do?
  1. Continue at the same speed in your lane
  2. Move over, or slow if you can't
  3. Stop completely in your lane
  4. Follow closely to get around it faster

Answer: Move over, or slow if you can't

You must move to a lane that isn't immediately adjacent to the stopped vehicle, or slow down and prepare to stop if you can't move over.

Handbook p. 37 ↗
Why do large trucks often move left before making a right turn?
  1. Because they are changing lanes to pass
  2. Because they are required to signal left first
  3. They need room for a wide turn
  4. To let cars pass them on the right

Answer: They need room for a wide turn

Trucks make wide turns and often move left first, so don't assume they are changing lanes and try to pass on the right.

Handbook p. 37 ↗
What should you do if a truck is stopped at or approaching an intersection and beginning to turn?
  1. Pass quickly on the right before it turns
  2. Pull directly behind it in its blind spot
  3. Stop past the stop line to be seen
  4. Never cut in along its right side

Answer: Never cut in along its right side

Never cut in along a turning truck's right side; you could become trapped between the truck and the curb.

Handbook p. 38 ↗
Fully loaded trucks can weigh more than 80,000 pounds but can stop in about the same distance as a car.
  1. True
  2. False

Answer: False

False. The handbook says fully loaded trucks can weigh more than 80,000 pounds and take the length of a football field to stop, so never cut in front of one.
