A roundabout is a circular intersection where multiple roads meet. It is also known as a traffic circle or rotary. Vehicles move around the roundabout in a clockwise direction and drivers entering the roundabout must yield to those already inside. Roundabouts are designed to improve traffic flow and reduce accidents compared to traditional intersections. They are commonly found in many countries, including the United States, United Kingdom, Australia, and Canada.
