Some things you pass need extra care. Bicyclists may swerve, parked cars may pull out, and trucks can't see you in their huge blind spots. Give each of them room, and don't linger where you can't be seen.

Passing a bicyclist:

  • Don't try to pass unless you have a clear and empty lane
  • Without enough space, slow to the cyclist's speed and follow until you have room
  • Avoid driving next to a bicyclist for long in a shared single lane
  • Reduce your speed when passing
  • When space allows, keep at least 3 feet between your vehicle and the bicyclist
Handbook p. 56 ↗

Clues that a parked car may pull out:

  • Exhaust coming from the tail pipe
  • Brake lights on, a turn signal flashing or white backup lights on
  • Front wheels turning out
  • A person sitting behind the wheel
Handbook p. 57 ↗

Know the rule

When passing parked cars, also watch for pedestrians or bicyclists crossing from between them.

Handbook p. 57 ↗

Know the rule

When passing a heavy vehicle, keep a consistent speed. Before pulling back in, be sure you can see both headlights and the entire cab in your rearview mirror.

100 feet

Length some double-trailer rigs can reach; allow for it when passing

Handbook p. 57 ↗

Know the rule

Don't loiter in a truck's blind spot, for example with cruise control set just faster than the truck, or when passing on the right. The driver can't see you or take evasive action.

Handbook p. 57 ↗

Know the rule

When approaching emergency vehicles parked by the road, you must move over or slow down.

Handbook p. 57 ↗

No-Zone

An area on either side of, or directly behind, a heavy vehicle where another vehicle isn't visible to the driver.

Handbook p. 93 ↗

Know the rule

A truck driver sits twice as high as a car driver and sees farther over traffic, but has large blind spots directly behind and on both sides that cars don't.

Handbook p. 58 ↗

Know the rule

Tailgating a truck puts you in its rear No-Zone, cuts your view of traffic ahead and exposes you to debris such as ice, rocks or tire recapping material.

Handbook p. 58 ↗

Right-turn squeeze

When a car ends up in the blind spot on the right side of a heavy vehicle that is turning right.

Handbook p. 58 ↗

Blind spot

The area near the right and left rear corners of a vehicle that can't be seen in the rearview mirrors. You must turn your head to see it.

Handbook p. 91 ↗
Truck no-zones (blind spots)
Stay out of trucks' No-Zones (blind spots)

Put it into practice

You're passing a tractor-trailer on the interstate. Don't pull back in as soon as you clear its bumper. Keep a steady speed until you see both of its headlights and the whole cab in your rearview mirror, then move over.

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 passing a bicyclist and space allows, how much separation should you maintain?
  1. At least 1 foot
  2. At least 10 feet
  3. No specific distance is required
  4. At least 3 feet

Answer: At least 3 feet

When space allows, maintain at least 3 feet of separation between your vehicle and a bicyclist you are passing.

Handbook p. 56 ↗
Some tractor-trailer rigs with double trailers can be how long, which affects how much room you need to pass safely?
  1. As much as 100 feet
  2. About 40 feet
  3. About 200 feet
  4. About 25 feet

Answer: As much as 100 feet

Some tractor-trailer rigs, particularly those with double trailers, can be as much as 100 feet long.

Handbook p. 57 ↗
Before pulling back into your lane after passing a heavy vehicle, what should you be able to see?
  1. Just the truck's front bumper
  2. Both headlights and the entire truck cab
  3. Only the truck's side mirror
  4. Only the truck's roof lights

Answer: Both headlights and the entire truck cab

Be sure you can see both headlights and the entire cab of the truck in your rearview mirror before pulling back into your lane.

Handbook p. 57 ↗
Why should you avoid loitering in a truck's blind spot while passing?
  1. It uses more fuel to match the truck's speed
  2. The truck's wind blast can push you off the road
  3. The driver can't see you or swerve to avoid a hazard
  4. Trucks are required to stay in the right lane

Answer: The driver can't see you or swerve to avoid a hazard

Loitering in a truck's No-Zone blind spot means the driver can't see you and can't take evasive action if needed.

Handbook p. 57 ↗
What causes a 'right-turn squeeze' involving a heavy vehicle?
  1. A truck passes a passenger vehicle too closely on the left
  2. A passenger vehicle brakes suddenly in front of a truck
  3. Two trucks attempt to turn right at the same time
  4. A car is in the truck's right-side blind spot as it turns right

Answer: A car is in the truck's right-side blind spot as it turns right

A right-turn squeeze occurs when a passenger vehicle is in the blind spot on the right side of a heavy vehicle that is turning right.
