traffic intersection From Wikipedia, the free encyclopedia
A roundabout (also known as a traffic circle or traffic island) is a road circle joining three or more roads. Drivers follow a simple rule to avoid crashes.
In countries that drive on the left:
The driver goes round the island in a clockwise direction.
In countries that drive on the right:
The driver goes round the island in an anticlockwise direction.
There are larger roundabouts that can have two to six lanes and can have traffic lights. These can sometimes be found at motorway junctions.
The term "gyratory" (for example, Hanger Lane gyratory) is sometimes used in the United Kingdom for a larger roundabout with unusual features.
