What behavior is expected of drivers approaching a roundabout?

When approaching a roundabout, drivers are expected to yield to traffic that is already circulating within the roundabout. This is crucial for ensuring a smooth flow of traffic and avoiding collisions. By yielding, drivers allow vehicles that are already in the roundabout to pass, which facilitates safer and more efficient merging into the circulating traffic.

This behavior is important because roundabouts are designed to reduce the risk of accidents by promoting continuous movement. By yielding instead of stopping completely or merging aggressively, drivers can decrease the likelihood of sudden stops or crashes. Additionally, giving way to the right-hand side is a fundamental rule in the design of roundabouts, as it aligns with the traffic flow direction.

While accelerating to merge or stopping completely may seem like viable options, they can disrupt the traffic flow and potentially lead to accidents. Similarly, signaling left at all times is not appropriate, as drivers should only signal left when they intend to exit the roundabout to the left. Understanding these dynamics of roundabout behavior enhances road safety for all users.
