What should a driver do when being passed by another vehicle?

When a driver is being passed by another vehicle, the recommended action is to stay in their lane and maintain a consistent speed. This approach helps to prevent any potential confusion or sudden movements that could lead to an accident. By maintaining speed, the driver allows the passing vehicle to complete the maneuver safely and efficiently.

This method is critical for ensuring a predictable environment on the road. Sudden changes in speed or lane position can increase the risk of collisions, particularly if the passing driver misjudges the gap or the speed at which the other vehicle is moving.

Options such as accelerating to let the vehicle pass quickly or changing lanes could lead to dangerous situations. Accelerating disrupts the expected dynamics of the maneuver, while changing lanes might confuse the passing vehicle about your intent. Slowing down can also be misleading because it might cause the passing driver to misjudge the safe distance needed to complete their pass, increasing the risk of an accident. Therefore, the safest and most advisable action is to remain in your lane and maintain your speed.
