Definition & Meaning of "roundabout"

What is a "roundabout"?

A roundabout is a circular intersection where traffic flows in one direction around a central island. Vehicles entering the roundabout yield to those already inside, allowing traffic to flow smoothly without the need for stop signs or traffic lights. Roundabouts are designed to improve safety and reduce congestion by lowering speeds and eliminating sharp turns. They are commonly used in places with high traffic volume or where multiple roads meet, as they help reduce the risk of accidents and keep traffic moving efficiently.
