What must you do if you approach a roundabout?

When approaching a roundabout, the correct action is to yield to traffic that is already in the roundabout. This is essential for maintaining the flow of traffic and ensuring safety for all drivers and pedestrians. By yielding, you allow cars that are already navigating the roundabout to pass, which helps prevent collisions and facilitates a smoother transition for vehicles entering and exiting the roundabout.

If you were to speed up to merge quickly, this could create a dangerous situation as it undermines the orderly movement of vehicles. Stopping and waiting for a green light is not applicable at a roundabout because they typically do not have traffic lights. Additionally, signaling right and entering immediately without yielding can lead to accidents as it disregards the priority given to vehicles already in the roundabout. Understanding this yielding process is crucial for safe driving in roundabout scenarios.
