Overview

Traffic in a roundabout moves in a counter clockwise direction around a central island. Vehicles entering the roundabout must yield to traffic already in the roundabout.

Differences between roundabouts and traffic circles

There are differences between traffic circles and roundabouts. The centre island of a roundabout is smaller than the centre island of a traffic circle. The roundabout has been designed with a tighter curve around the island to encourage lower speeds and may have a sloped curb to allow more room for larger commercial vehicles. Roundabouts can be a safer alternative to traffic circles in high-traffic areas.
