Roundabouts are becoming more common in the U.S. because they provide safer and more efficient traffic flow than standard intersections.

By keeping traffic moving one-way in a counterclockwise direction, there are fewer conflict points and traffic flows smoothly.

Crash statistics show that roundabouts reduce fatal crashes about 90%, reduce injury crashes about 75%, and reduce overall crashes about 35%, when compared to other types of intersection control. When driving a roundabout, the same general rules apply as for maneuvering through any other type of intersection.

Truck apron

Large vehicles need more space when driving in a roundabout. A truck apron is a paved area on the inside of the roundabout for the rear wheels of large trucks to use when turning. Truck aprons are not to be used by cars, SUVs or pickup trucks.

Steps for Driving a Roundabout
  1. Slow down. Obey traffic signs.
  2. Yield to pedestrians and bicyclists.
  3. Yield to traffic on your left already in the roundabout.
  4. Enter the roundabout when there is a safe gap in traffic.
  5. Keep your speed low within the roundabout.
  6. As you approach your exit, turn on your right turn signal.
