Changing lanes, merging and passing all mean moving into space other traffic may want. Do it in a set order: check, signal, check again, move. And pass only where signs, markings and conditions allow.

Before changing lanes:

  • Check your mirrors
  • Check blind spots with head checks
  • Find a gap, signal, and look again in the direction of the lane change
  • Adjust speed and steer into the lane
Handbook p. 23 ↗

Know the rule

Entering a multi-lane highway: use the acceleration lane to reach the speed of traffic, find a gap and merge.

Handbook p. 23 ↗
Merging onto a highway
Merging: adjust speed, check for a gap, merge

Exiting a roadway:

  • Move to the lane closest to the exit early, to avoid a quick lane change
  • Keep your speed while on the main roadway
  • Check the posted speed for the deceleration lane
  • Signal, move into the deceleration lane, and slow to exit speed
Handbook p. 23 ↗

Know the rule

Pass only where signs or markings permit and conditions are favorable. On multi-lane roads the left-most lane is for passing slower vehicles.

Handbook p. 24 ↗

Do NOT pass:

  • When an oncoming vehicle is approaching
  • When a curve or hill blocks your view
  • At intersections
  • Before a highway-railroad crossing or a bridge
  • On the shoulder, paved or not
Handbook p. 24 ↗

Passing steps:

  • Check for oncoming traffic
  • Check mirrors and/or do a head check
  • Signal when it's safe; steer smoothly into the passing lane
  • Keep passing until the whole front of the passed vehicle shows in your rearview mirror
  • Signal, then steer smoothly back into the lane
Handbook p. 24 ↗
Angle parking maneuver
Passing: move out, pass, return once the vehicle shows in your mirror

When being passed:

  • Stay in your lane
  • Keep a constant speed
  • Never speed up to prevent someone from passing
Handbook p. 24 ↗

Put it into practice

You're passing a slow truck on a two-lane road. Don't cut back as soon as your rear clears it. Wait until you can see the truck's entire front in your rearview mirror, signal, then move back.

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.

What should a driver check before changing lanes, besides the mirrors?
  1. The speedometer reading
  2. Blind spots, using head checks
  3. The vehicle directly ahead only
  4. The lane lines behind the car

Drivers must check blind spots with head checks in addition to mirrors before changing lanes.

  2. On the shoulder
  3. On a four-lane divided highway
  4. In the left lane of a multi-lane road

Answer: On the shoulder

Never pass on the shoulder, whether paved or not.

Handbook p. 24 ↗
When should a driver stop passing and consider it complete?
  1. As soon as the driver's door passes the other vehicle's bumper
  2. After signaling for 3 seconds
  3. When both vehicles are side by side
  4. When the whole front vehicle shows in the rearview mirror

Answer: When the whole front vehicle shows in the rearview mirror

Continue passing until the entire front of the passed vehicle is visible in the rearview mirror.

Handbook p. 24 ↗
What should a driver being passed do?
  1. Flash their high beams repeatedly
