What should you do if an overtaking car is approaching rapidly on your side of a single-lane two-way roadway?

When an overtaking car is approaching rapidly on your side of a single-lane two-way roadway, the best course of action is to change your position and adjust your speed. This means you should safely maneuver your vehicle to allow the overtaking car to pass. It may involve moving to the right side of your lane, which provides more space for the overtaking driver and can help prevent a collision. Adjusting your speed in this situation helps to create a safer environment for both you and the other driver, ensuring that there is enough distance for the overtaking maneuver to be completed comfortably.

Altering your position and speed demonstrates defensive driving, which is crucial in situations where lane sharing is precarious. It's also a proactive measure that can avoid potential accidents, as it takes into account the actions of other drivers and the need to keep traffic flowing smoothly. This strategy is preferable in scenarios where sudden changes, like switching lanes abruptly or accelerating to pass, could lead to dangerous outcomes.
