If another vehicle is passing you on the left, what should you not do?

When you are being passed by another vehicle, increasing your speed is not advisable. The correct course of action is to allow the passing vehicle to maneuver safely without adding any complications. Speeding up can create a dangerous situation, as it may not give the other driver enough time or space to complete the pass safely. Maintaining a steady speed or even reducing your speed can enhance road safety by giving the passing vehicle a clear opportunity to move ahead.

Changing your lane in this scenario could also be dangerous. If you change lanes while another vehicle is attempting to pass you, you may collide with the passing vehicle, which could lead to an accident. Signaling your turn is unnecessary and could be misleading to other drivers, especially if your intent was not to change direction. Reducing your speed can create a more predictable driving environment, allowing the other vehicle to pass and return to your lane safely.
