When passing another vehicle, what must the driver of the car being passed do?

When passing another vehicle, it's important for the driver being passed to maintain their speed. This action prevents confusion during the maneuver and allows the passing driver to execute the pass safely and efficiently. If the driver being passed reduces their speed or changes lanes unexpectedly, it can increase the risk of a collision or create an unsafe situation for all drivers involved.

By maintaining their speed, the driver provides a clearer indication of their position on the road and ensures that the passing vehicle has enough space to complete the maneuver safely. This consistency in speed makes it easier for the passing vehicle to judge the timing and distance necessary to move back into the lane safely. Additionally, it's worth noting that increasing speed unnecessarily is also discouraged, as it can lead to unsafe driving conditions and could complicate the passing process.

In summary, while the driver being passed should not slow down or speed up erratically, maintaining a steady speed allows for safer and smoother passing dynamics on the road.
