In a roundabout, a driver must drive in:
Answer: A — clockwise direction
In a roundabout, drivers must drive in a clockwise direction. This is to ensure smooth traffic flow and safety for all vehicles entering and exiting the roundabout. Driving in a counterclockwise direction, in the opposite direction, or any direction other than clockwise would lead to confusion, potential collisions, and disrupt the efficient functioning of the roundabout. Therefore, option A is the correct choice for driving in a roundabout in compliance with traffic rules and regulations.
