What is a Roundabout?

Image of Typical Roundabout A roundabout is a circular intersection design increasingly being used by MDOT. While some people use the term "roundabouts" and "traffic circles" interchangeably, they are not the same thing. Here's how they differ: roundabouts are typically smaller than traffic circles, and drivers must yield to vehicles already in the roundabout before entering.

Roundabouts have been proven to safely decrease traffic delays and congestion. When selected and designed correctly, roundabouts can handle a high volume of traffic, including commercial trucks and large emergency vehicles. Roundabouts can cost less than traditional signalized intersections.
