In Washington, what must a driver do when approaching a roundabout?

Answer: A — Yield to traffic already in the roundabout

When approaching a roundabout in Washington, it is important for a driver to yield to traffic that is already in the roundabout. This is crucial because vehicles already circulating within the roundabout have the right of way, allowing for smoother traffic flow and reduced potential for collisions. By yielding, drivers are ensuring they do not interfere with the established traffic patterns, which helps in maintaining safety for all road users. The concept of yielding at roundabouts is designed to facilitate continuous movement and minimize delays compared to traditional intersections where stop signs or signals may be employed. Therefore, recognizing and adhering to this rule is key for effective navigation through roundabouts, contributing to overall traffic efficiency and safety.
