If a vehicle behind you starts to pass, what should you do?

When a vehicle behind you starts to pass, the safest and most courteous action is to move as far to the left as possible. This creates additional space for the passing vehicle, helping to minimize the risk of a collision. By moving to the left, you maintain a safe distance between your vehicle and the one attempting to overtake, allowing them the freedom to complete the maneuver without feeling squeezed or uncertain.

Maintaining your speed, accelerating, or honking your horn, could potentially increase the risk of an accident. Maintaining speed might not provide enough room for the passing vehicle, while accelerating could make it difficult for the other driver to get past safely. Honking might not be helpful in this situation and could startle the other driver, leading to erratic behavior. Therefore, moving to the left is the best option in this scenario.
