A diagram of movement within a roundabout in a country where traffic drives on the left. A roundabout is a type of road junction, or traffic calming device, at which traffic streams circularly around a central island after first yielding to the circulating traffic. Unlike with traffic circles, vehicles on a roundabout have priority over the entering vehicle, parking is not allowed and pedestrians are usually prohibited from the central island.
