Why do we use roundabouts?

Roundabouts are often used in new or remodeled intersections to lower the incidence of crashes. View Video


The Insurance Institute for Highway Safety has a video featuring roundabouts.


Better safety

Roundabouts show a 39 percent decrease in all crashes and an 89 percent decrease in fatal crashes.  More


Better traffic flow

Roundabouts can handle high levels of traffic with less delay than most stop signs or signals.


The tight curves slow traffic so entering and exiting are easier and more efficient.


Better fuel efficiency and air quality

Where roundabouts replace signals, idling decreases which reduces vehicle emissions and fuel consumption by 30 percent or more.

See Minnesota Driver's Manual, Chapter 3, page 28 (PDF).


Cyclists can either ride with traffic inside the roundabout or use the crosswalks appropriately.


Cyclists who ride with traffic must follow the same rules as vehicles and must yield as they enter the roundabout.  Since traffic moves slowly in the circle, cyclists should be able to travel at or near the same speed as motorists, staying in line with circulating traffic.



Cross only at crosswalks, and always stay on the designated walkways. Never cross to the central island. Cross the roadways one direction at a time. Use the median island as a halfway point where you can check for approaching traffic.
