Approaching and Entering

  • When approaching a roundabout, slow down and be prepared to yield to pedestrians in the crosswalk.
  • Pull up to the yield line, look to the left for approaching traffic within the roundabout. If there’s no traffic, proceed counterclockwise at 15 to 20 miles per hour. Remember, circulating traffic has the right-of-way. Entering traffic must yield the right-of-way to circulating traffic.
  • Enter the roundabout when there is an adequate gap in circulating traffic. Proceed to your right. Vehicles travel counterclockwise around a raised center island.


In the Roundabout

  • Once in the roundabout, drivers proceed counterclockwise to the appropriate exit, following the guidance provided by traffic signs and pavement markings. Once in the roundabout, you now have the right-of-way. You shouldn’t have to stop.
  • Stay off the slightly raised truck apron unless needed by a larger turning radius vehicle.



  • As you approach your exit, use your right turn signal if possible.
  • Watch for pedestrians in the crosswalk and be prepared to yield.
  • Slowly exit the roundabout.
