What should you do when approaching a roundabout?

Answer: B — Yield to traffic already on the roundabout

When approaching a roundabout, it is essential to yield to traffic that is already circulating within the roundabout. This practice ensures a smoother flow of vehicles and helps prevent collisions. By yielding, you allow those already on the roundabout the right of way, which minimizes disruptions and enhances safety for all road users. The design of roundabouts is such that vehicles inside it have the priority. This means as you approach, you should slow down, assess the traffic situation, and only enter when it is safe to do so. Yielding is crucial, as it helps maintain the efficiency of the roundabout and reduces the likelihood of accidents. In contrast, speeding up to enter quickly could lead to dangerous situations, as it may result in ignoring traffic already in the roundabout. Ignoring the roundabout altogether is not a safe option, as it puts you and other drivers at risk. Finally, always stopping before entering is unnecessary and could cause confusion or disrupt traffic flow, especially if there is no traffic present. Hence, yielding to traffic already on the roundabout is the most appropriate and safe action to take in this scenario.
