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

Answer: B — Maintain your speed

Maintaining your speed when another vehicle is passing you on the left is the correct approach for several reasons. First, it helps ensure that the passing vehicle can do so safely and efficiently. When you speed up, it may create confusion and increase the risk of an accident, as the passing vehicle may not expect a change in your speed. On the other hand, by keeping your speed consistent, you allow the other driver to complete the maneuver successfully without feeling rushed or pressured. Additionally, it's vital for drivers to be predictable in their actions. Sudden changes, like speeding up or stopping, can lead to dangerous situations on the road. By maintaining your speed, you contribute to a safer driving environment for everyone. In this scenario, other options like stopping immediately or turning on hazard lights are not appropriate and could lead to confusion or additional hazard on the road.
