When passing another vehicle, what is required of drivers?

Answer: B — To return to the right as soon as possible

When passing another vehicle, it is essential for drivers to return to the right lane as soon as it is safe to do so after completing the maneuver. This practice ensures that the left lane, which is typically designated for overtaking, is available for other drivers who may also need to pass. Returning to the right side contributes to a smoother traffic flow and reduces the risk of collisions by preventing extended periods of time in the left lane. In many driving situations, remaining in the passing lane longer than necessary can lead to frustration for other drivers and may encourage unsafe driving behavior. Therefore, the requirement is to return to the right after passing, maintaining overall safety and efficiency on the road.
