What are roundabouts?

Answer: A — Circular intersections

Roundabouts are circular intersections designed to improve traffic flow and enhance safety. They allow vehicles to enter and exit in a continuous, circular motion, which helps to eliminate the need for traffic signals or stop signs at the intersection. This design promotes efficient movement and reduces the likelihood of high-speed collisions compared to traditional intersections. In a roundabout, vehicles traveling in the circle have the right of way, which helps to prevent accidents and reduce congestion as drivers yield to those already in the roundabout before entering. The circular structure of roundabouts encourages lower speeds, making it safer for both vehicles and pedestrians. The absence of traffic lights or stop signs is a key feature that distinguishes them from other types of intersections, such as traffic light controlled intersections, two-way stops, or one-way streets, which operate under different traffic management principles.
