What should you do if you approach a roundabout?

Answer: B — Yield to traffic already in the roundabout

When you approach a roundabout, yielding to traffic already in the roundabout is essential for ensuring safety and smooth traffic flow. Vehicles that are already circulating in the roundabout have the right of way, and this helps prevent collisions and allows for seamless navigation. This rule promotes a safe merging process, as drivers can enter the roundabout when there's a sufficient gap in traffic. It’s important to assess the flow of vehicles and wait for an appropriate moment to enter, ensuring you are not cutting off or colliding with vehicles already in the roundabout. In addition to promoting safety, yielding to traffic helps maintain the efficiency of the roundabout, allowing vehicles to flow without unnecessary stops and delays. Following this rule also sets a good example for other drivers, supporting an environment where everyone adheres to the traffic norms necessary for conclusive road safety.
