Question 4105

Must you reduce your speed to make it easier for another vehicle to pass?

  1. No, the one who must reduce speed is the driver approaching from the opposite direction.
  2. Yes, to make it easier for the passing vehicle to return to the right lane if the pass is dangerous.
  3. No, under no circumstances.
Show answer and explanation

Correct answer: Yes, to make it easier for the passing vehicle to return to the right lane if the pass is dangerous.

Yes. If a hazard arises while someone is passing you, you must slow down so they can finish and return to their lane ahead of you. In the image, the red passenger car is passing in the oncoming lane and a white van is approaching, so the gray car brakes to let the red car move back in ahead. This obligation is yours, not the oncoming driver's.
