When passing, what must drivers do as soon as possible?

When passing another vehicle, it is crucial for drivers to safely return to the right lane after completing the maneuver, without impeding the vehicle being passed. This ensures that the vehicle being overtaken is not disrupted or forced to brake or change its speed abruptly, contributing to overall road safety.

The importance of quickly returning to the right lane lies in maintaining a smooth flow of traffic. Once a driver has overtaken another vehicle, lingering in the left lane can create unnecessary hazards for other drivers who may be attempting to pass or maintain their speed.

By ensuring their return to the right lane is done safely and promptly, drivers exhibit responsibility and awareness of their surroundings, which are essential principles of defensive driving. This practice also helps prevent potential collisions and keeps traffic moving efficiently.
