What action should a driver take when approaching a roundabout?

Answer: B — Yield to traffic already in the roundabout

When approaching a roundabout, it is essential for a driver to yield to traffic that is already inside the roundabout. This practice ensures a smooth flow of traffic and helps prevent collisions. Roundabouts are designed to facilitate the continuous movement of vehicles while minimizing the potential for accidents that can occur at traditional intersections. By giving way to vehicles that are already circulating, the driver is not only adhering to road safety rules but also contributing to efficient traffic flow. The rules related to yielding in roundabouts help create clear expectations for drivers, which can reduce confusion and improve overall safety. Understanding this concept is crucial for navigating roundabouts effectively and safely, ultimately supporting better traffic management in these areas.
