Roundabout Information

 

What is a Roundabout?

Modern roundabouts are a common form of unsignalized intersection control in use throughout the world. In a roundabout intersection, one-way traffic moves around a central island, and entering traffic must yield to circulating traffic. Modern roundabouts maximize safety by significantly reducing conflict points and minimize traffic delay due to the efficiency of yielding as opposed to required stopping at traditional intersections. Roundabouts are also more cost effective than traffic lights as they eliminate hardware, maintenance and electrical costs associated with the signals.

On this page is additional information created by the Federal Highway Administration and other state Departments of Transportation to learn more about modern roundabouts and how to use them.
