Roundabouts

​A roundabout is a circular intersection where traffic flows around a center island. They can be used as an alternative for traffic signals and stop signs and have many benefits. According to the U.S. Department of Transportation:

  • They reduce crashes with fatalities by 90 percent.
  • They reduce crashes with injuries by 76 percent.
  • They reduce crashes with pedestrians by 30–40 percent.
  • They increase traffic capacity by 30–50 percent.
  • They reduce pollution and fuel use.
  • They save money installation and repair costs.


Navigating a roundabout
As a general rule, the flow of traffic in a roundabout is counter-clockwise. Enter the roundabout when there is a safe gap in traffic and yield to pedestrians in the crosswalk.

Once in the roundabout, don’t stop (except for crashes) and don’t pass other vehicles or bicyclists.
