What should you do while being passed in a passing zone?

Answer: C — Slow down and let the vehicles safely return to the drive lane

When you are being passed in a passing zone, slowing down to allow the vehicle sufficient space and time to safely return to your driving lane is the best practice. This action enhances safety for both you and the passing vehicle, reducing the chance of a collision. Maintaining a steady speed or accelerating could create an unsafe situation, as it may make it more difficult for the other driver to complete their maneuver safely. Changing lanes to the right can also be problematic, especially if other vehicles are already in that lane or if it’s not safe to move over. Therefore, slowing down is the most responsible approach when being passed, as it helps maintain safe driving conditions.
