How should you approach a roundabout?

Answer: B — Yield to traffic already in the roundabout and enter when clear

To approach a roundabout safely and effectively, it's important to yield to traffic that is already circulating within the roundabout. This ensures that you enter the roundabout when it is clear, allowing for the smooth flow of traffic and minimizing the risk of collisions. The priority in a roundabout is for vehicles already inside to maintain their right of way, so waiting for a gap in traffic before entering is crucial. By yielding and waiting for a safe opportunity to proceed, you contribute to the efficiency of the roundabout system, which is designed to reduce the need for stops and enhance traffic flow compared to traditional intersections.
