What is the correct action when approaching a roundabout?

When approaching a roundabout, the correct action is to yield to traffic that is already inside the roundabout. This rule is designed to maintain a steady flow of traffic and ensure safety. By yielding, you allow vehicles already circulating in the roundabout to proceed without interruption, which minimizes the likelihood of collisions and keeps the roundabout functioning effectively.

It is important to understand that stopping before entering a roundabout is not always necessary unless there is a specific reason to do so, such as a stop sign or traffic light ahead. Entering without yielding can create chaos and potential accidents as it disrupts the flow of traffic already in the roundabout. Additionally, signaling left before entering is not standard procedure; drivers typically signal their exit from the roundabout rather than their intention to enter. Thus, yielding to existing traffic is crucial for safe and efficient navigation through a roundabout.
