Alberta Driver's Handbook

Drivers entering the circular intersection must yield to drivers already in the circle. Once in the circle, drivers must activate the right signal when preparing to exit.

Drivers using the left lane to enter the circle must do so when it is safe and stay in the left lane while in the circle/roundabout. They must exit using the left lane. Drivers planning to travel past the first exit should use the left lane to enter and exit.

While in the circle, the driver on the right must yield to the driver on the left. Activate the right signal when preparing to exit. Use caution when exiting and crossing through the right (outside) lane.
