You are driving behind a motorcycle and want to pass. You must:

  1. Stay in the right lane as much as possible because the motorcycle is small and doesn't use all of the lane.
  2. Blow your horn to make the motorcycle move onto the shoulder so that you can pass.
  3. Have your vehicle entirely in the left lane before and during the pass. ✓

Answer: C. Have your vehicle entirely in the left lane before and during the pass.

To pass a motorcycle, keep your vehicle completely in the left lane before and while you go around it.

Why this is the answer

The handbook treats motorcyclists as having the same rights and responsibilities as other drivers. It says to give a motorcycle the full lane and never to pass one in the same lane you are sharing. That means you should not squeeze past within the motorcycle's lane. Instead, move into the adjacent lane and complete the pass there, with your vehicle fully in that lane before and during the pass. The passage does not spell out the exact wording about being entirely in the left lane, but that follows from the rule against passing in the same lane.

Why the other answers are wrong

Remember it

Think 'whole lane for the motorcycle': if you go around, your car belongs in the next lane, not beside the bike.
