What is the correct action when approaching a roundabout?

When approaching a roundabout, the correct action is to yield to traffic already in the roundabout. This is essential because vehicles inside the roundabout have the right of way, allowing for a smooth flow of traffic. Yielding helps prevent collisions and ensures that all vehicles can navigate the roundabout safely.

Entering quickly can disrupt the flow and create dangerous situations, while signaling right upon entering does not apply until you are preparing to exit. Stopping before entering is not necessary as long as you yield to any traffic already in the roundabout. Recognizing the proper procedures at a roundabout is crucial for maintaining order and safety on the road.
