You want to pass a bicyclist in a narrow traffic lane when an oncoming vehicle is approaching. You should:

  1. Honk your horn then pass the bicyclist.
  2. Slow down and let the vehicle pass you before you pass the bicyclist. ✓
  3. Wait until the bicyclist rides off the roadway.

Answer: B. Slow down and let the vehicle pass you before you pass the bicyclist.

Slow down and let the oncoming vehicle pass you before you pass the bicyclist.

Why this is the answer

The handbook describes exactly this situation: a bicyclist ahead on your right and an oncoming vehicle on your left. It says not to drive between them, but to take one danger at a time. Slow down and let the oncoming vehicle go by first. After it has passed, move left to leave plenty of space, at least three feet, when you pass the bicyclist.

Why the other answers are wrong

Remember it

When two hazards line up, handle one before the other: let the oncoming car clear, then give the bike room.
