When approaching a roundabout, a driver must yield to traffic that is already circulating within the roundabout. This is a key safety rule designed to ensure a smooth flow of vehicles and minimize accidents. Vehicles already in the roundabout have the right of way, which prevents confusion and potential collisions.
By yielding, drivers can assess the situation and enter the roundabout when it is safe to do so. This practice also encourages the efficient use of the roundabout, as it allows for continuous movement of traffic with minimal stops compared to traditional intersections.
Understanding this rule is critical, as it sets the foundation for navigating roundabouts safely. Other actions, such as speeding up to enter quickly or ignoring yield signs, compromise safety and disrupt the intended function of the roundabout as a traffic management solution.
