If we arrive at an unsignalled intersection and cyclists are approaching from our left, must we give way to them?
A)Yes.
B)No.Correct
C)Yes, if they are travelling in a group.
At an intersection with a group of cyclists we will apply the right-of-way rule. If one of the cyclists has already crossed the intersection we must wait until the entire group has finished passing, since they are considered as a single unit.

Bicycle riders have right of way over motor vehicles:
- When travelling along a bike lane, cyclist crossing or properly signed shoulder.
- When, in order to enter another road, the motor vehicle turns right or left, in the cases permitted, and there is a cyclist nearby.
- When travelling in a group, the first one has already started crossing or has entered a roundabout.
