When passing another vehicle on a road with two lanes traveling in opposite directions, you should:

  1. Return to the driving lane when there's enough room between you and the vehicle you passed. ✓
  2. Remain in the left lane if you intend to turn left.
  3. Return to the right side of the roadway immediately.
  4. Drive in either lane.

Answer: A. Return to the driving lane when there's enough room between you and the vehicle you passed.

You should return to the driving lane when there is enough room between you and the vehicle you passed.

Why this is the answer

Pass on the left, and stay out of the right lane until you have safely cleared the vehicle you passed. The handbook says to wait until you can see that car in your rearview mirror before returning to the right lane. That gives you enough room so you do not cut off the driver you just passed. The answer matches this rule: you return to the driving lane when there is enough room between you and the vehicle you passed, not at some fixed instant.

Why the other answers are wrong

Remember it

Use your rearview mirror as the sign that the passed car is far enough behind before you move right.
