If another vehicle is passing you on the left, what should you do?

When another vehicle is passing you on the left, the safest and most appropriate action is to refrain from increasing your speed. This is important because increasing your speed can create an unsafe situation for both you and the passing vehicle. By maintaining a steady speed, you allow the passing vehicle to safely maneuver back into the lane in front of you without feeling threatened or pressured.

Changing lanes to the right might not be practical or safe depending on the traffic and road conditions. It could lead to abrupt lane changes that may confuse other drivers and increase the risk of collisions. Speeding up to stay ahead can lead to aggressive driving habits and increases the chances of an accident, as it can catch the other driver off-guard. Staying in the same lane and keeping your speed despite the passing vehicle could be risky if it creates an unsafe interaction. Thus, maintaining a steady speed is the best course of action to ensure a safe and predictable driving environment.
