What should drivers do when they encounter a roundabout?

When approaching a roundabout, drivers must yield to vehicles already circulating within the roundabout. This is crucial for maintaining a smooth flow of traffic and preventing collisions. By yielding, drivers allow those in the roundabout to continue without interruption, facilitating safe entry and exit.

Yielding to traffic in the roundabout helps to ensure that drivers can merge safely and reduces the likelihood of accidents. It also aligns with the overall design of roundabouts, which are intended to improve traffic flow compared to traditional intersections.

In contrast, entering immediately without stopping can lead to dangerous situations where vehicles collide due to the lack of proper yielding. Signaling left to exit may also be misleading since generally, drivers should signal when they are about to exit, but not necessarily left while in the roundabout. Stopping before entering can cause unnecessary delays and disrupt the flow of traffic, as it contradicts the purpose of roundabouts, which is to keep traffic moving efficiently.
