What Is a Roundabout?
A roundabout is a circular intersection where traffic flows in one direction around a central island. Roundabouts are becoming more common across the United States because they reduce accidents and keep traffic moving. They appear frequently on the DMV test.
The Basic Rules
Yield on entry. Always yield to traffic already in the roundabout. Wait for a safe gap before entering.
Turn right to enter. In the US, roundabouts flow counterclockwise. You always enter by turning right.
Do not stop inside the roundabout. Once you are in the roundabout, keep moving. Traffic inside has the right of way.
Signal before you exit. Use your right turn signal to indicate you are exiting the roundabout.
Multi-Lane Roundabouts
Multi-lane roundabouts have two or more lanes. Choose the correct lane before you enter. For right turns or going straight, use the right lane. For going straight or turning left, use the left lane. Signs and lane markings before the roundabout will guide you.
Common Mistakes
Stopping inside the roundabout when you should keep moving. Changing lanes inside the roundabout. Entering without yielding to traffic already in the circle. Forgetting to signal when exiting.
Emergency Vehicles in Roundabouts
If an emergency vehicle approaches while you are in a roundabout, continue to your exit and then pull over. Do not stop inside the roundabout.
