BC defines a roundabout with having a median divider on approach to the circle. A traffic circle does not have a median and was the predecessor to the modern roundabout. The rules state that a signal is not required to enter the traffic circle or the roundabout. The roundabout does however require a signal right when exiting the circle; the traffic circle does not. It is advisable to use the left signal when going more than one exit in the traffic circle/roundabout, as most North Americans do not use these types of intersections well for clear communication and the benefit of other motorists.
