What should you do when you approach a roundabout?

Answer: A — Yield to traffic already in the roundabout

When you approach a roundabout, yielding to traffic already in the roundabout is essential for ensuring a smooth flow of traffic and avoiding accidents. Roundabouts are designed to allow vehicles inside the circle to have the right of way, which helps minimize collisions and promotes a continuous movement of vehicles. By yielding, you allow those already circulating to proceed without interruption, which is crucial for maintaining order and safety at this type of intersection. Entering without checking for other vehicles can lead to conflicts and potential accidents. Stopping and waiting for a green light is not how roundabouts operate, as they do not have traffic signals; instead, the flow is managed by yielding. Additionally, while roundabouts may generally be navigated to the left, mandating always going left is not accurate since some may need to navigate to the right depending on the layout and destination. Hence, prioritizing yielding to traffic already in the roundabout is the best practice.
