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 important because roundabouts are designed to facilitate continuous traffic flow and reduce the likelihood of accidents by minimizing conflict points. By yielding, you ensure that you are allowing vehicles that are already circulating in the roundabout the right of way, which helps maintain a smooth and safe flow of traffic.

Failing to yield can create confusion and increase the risk of collisions, as vehicles entering the roundabout without yielding may interfere with those already circulating. It's also essential to use turn signals when exiting the roundabout to communicate your intentions to other drivers, promoting safety and clarity for all road users.
