Choosing the right lane keeps traffic flowing and leaves room around you. Smooth driving also improves fuel economy. On a multi-lane road each lane has a job—and on a limited access highway, the left lane isn't for cruising.

Know the rule

Remaining in the left lane on a limited access highway is illegal.

Handbook p. 52 ↗

Know the rule

Turn into the lane nearest you. From a street with two or more lanes, turn left from the lane nearest the center lane and right from the lane nearest the curb. Change lanes only after finishing the turn, when traffic is clear.

Blind spots

Areas around your vehicle you can't see in the mirrors. Check them by turning your head and looking over your shoulder in the direction you plan to move.

Handbook p. 52 ↗

Changing lanes:

  • Check your mirrors
  • Check your blind spot over your shoulder
  • Find a gap, signal, and look again toward the lane
  • Adjust speed and steer into the lane
Handbook p. 52 ↗

Know the rule

Entering a multi-lane highway: use the acceleration lane to reach the speed of traffic, find a gap, merge, and cancel your signal. Traffic already on the highway has the right-of-way.

Handbook p. 53 ↗

Exiting a roadway:

  • Get into the lane closest to your exit early to avoid a quick lane change
  • Keep your speed while you're still on the main road
  • Signal, move into the deceleration lane, then slow down
  • Check the posted speed for the deceleration lane
Handbook p. 53 ↗

Put it into practice

You're cruising in the left lane of a three-lane interstate with no one to pass. Move right: the left lane is for passing, and staying in it on a limited access highway is illegal.

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.

On a road with three or more lanes in one direction, the left lane is generally for:
  1. Slower-moving traffic
  2. Passing or turning left
  3. Trucks and buses only
  4. Vehicles entering the highway

Answer: Passing or turning left

The left lane is for drivers who want to pass or turn left, while the right lane serves slower or entering/turning traffic.

Handbook p. 52 ↗
Remaining in the left lane on a limited access highway when not passing is:
  1. Legal only for trucks
  2. Illegal
  3. Legal if traffic is light
  4. Legal but discouraged

Answer: Illegal

The manual explicitly states remaining in the left lane on a limited access highway is illegal.

Handbook p. 52 ↗
When changing lanes, after checking your mirrors you should also check your blind spot by:
  1. Using only your peripheral vision
  2. Relying on mirrors alone
  3. Turning your head and looking over your shoulder
  4. Glancing at your inside rearview mirror

Answer: Turning your head and looking over your shoulder

You should check blind spots by turning your head and looking over your shoulder before changing lanes.

Handbook p. 52 ↗
When entering a multi-lane highway, you should use the acceleration lane to:
  1. Come to a complete stop before merging
  2. Wait for a gap at low speed
  3. Match traffic speed before merging
  4. Pass slower vehicles

Answer: Match traffic speed before merging

Use the acceleration lane to reach the speed of other vehicles before pulling onto the roadway.

Handbook p. 53 ↗
When merging onto a highway from the acceleration lane, the merging vehicle has the right of way over traffic already on the roadway.
  1. True
  2. False

Answer: False

False. The existing traffic has the right of way, so you must make sure it is clear before you merge.

Handbook p. 53 ↗
When turning left from a street with two or more lanes, you should turn from the lane:
  1. Nearest the center lane
  2. Any lane, since position doesn't matter
  3. Nearest the curb
  4. Farthest from the center

Answer: Nearest the center lane

When turning left from a multi-lane street, turn from the lane nearest the center lane.
