A roundabout is a circular intersection where two or more roads meet. Vehicles travel in a counterclockwise direction. Vehicles entering a roundabout must yield to traffic already in the roundabout.

Benefits of roundabouts

• All vehicles need to slow down to use a roundabout.
• With lower speeds and fewer points of conflict between vehicles, they reduce the potential for serious crashes and injury.
• Yielding at the entry of a roundabout takes less time than waiting for a gap in traffic at a stop sign.
• Fewer delays reduce fuel consumption and improve air quality by reducing emissions.
• There is an area for landscaping on the central island of a roundabout.

Using a roundabout

These tips will help you understand how to drive through a roundabout.

Approaching the roundabout

• Slow down.
• Choose your lane. Look for lane designation signs and pavement markings approaching the roundabout and stay in the lane assigned for your movement. 
• Keep to the right of the splitter island.
• Pay special attention to people walking and cycling who may be crossing the roadway. Yield to pedestrians crossing at the crosswalk.
• Once you have passed the crosswalk, yield to traffic already driving through the roundabout.
• Enter when there is a safe gap in traffic.

Driving in the roundabout

• Keep to the right of the centre island and drive in a counterclockwise direction until you reach your exit.
• Follow the pavement markings and stay in your designated lane until exit.
• Do not stop inside the roundabout, except to avoid a collision.

Leaving the roundabout

• Use your right-turn signal.
• Yield to pedestrians crossing at the crosswalk.
• If you miss your exit, continue around the roundabout again and then exit.
