When approaching a traffic circle, what must you do?

When approaching a traffic circle, it is crucial to enter and yield to the traffic that is already in the circle. This is based on the principle that vehicles already in the roundabout have the right of way, which helps to ensure smooth traffic flow and reduce the likelihood of collisions. Yielding to circulating traffic allows you to assess whether it is safe to enter and helps prevent blocking vehicles already navigating the circle.

By following this rule, drivers can maintain the movement and efficiency of the roundabout, which is designed to manage intersections more effectively compared to traditional stop signs or traffic lights. Understanding this gives drivers the awareness they need to navigate traffic circles safely and effectively.
