The driver of the green car, while driving in the left lane of a two-lane road, sees a vehicle stopped on the right shoulder, partially blocking the far right lane. The blue car is attempting to pass the green car. What should the driver of the green car do to clear the scene safely?

The driver of the green car must slow down and stay alert to the surroundings.

Explanation:

Devising well in advance that there must be some reason behind the slowing down of a vehicle right in the middle of a highway, the driver of the green car should reduce the speed of his vehicle and check whether it is safe to pass. While doing so, the driver must be vigilant enough to check the other vehicles approaching.
