What should you do when approaching a roundabout?

Answer: C — Yield to the traffic in the roundabout

When approaching a roundabout, yielding to the traffic already in the roundabout is essential for safety and smooth traffic flow. Vehicles within the roundabout have the right of way, and it is crucial to give them space to navigate without interruptions. This practice helps prevent collisions and ensures that traffic moves efficiently. In contrast to yielding, speeding up to merge quickly can lead to dangerous situations, as you might not be able to gauge the speed and distance of oncoming vehicles in the roundabout. Ignoring traffic signals, where applicable, is also unsafe, as signals are designed to guide traffic behavior and enhance overall safety in the area. Turning around is not a practical option when approaching a roundabout; doing so could create confusion and disrupt the flow of traffic. Thus, the best practice is to yield to the traffic already in the roundabout to maintain safety and order.
