If when reaching an intersection a group of cyclists approaches from the left side and the first one of the group has already started to pass, must you yield to them?
A)Yes to the first but not to the rest of the group, since they are approaching from the left.
B)Yes, since I must treat them as if they were a single unit.Correct
C)Yes, since by approaching from the left they have priority.
If we and the cyclists arrived simultaneously, we would have priority since the cyclists are coming from the left. But if we arrive at the intersection when the first cyclist of the group has already started to pass, we must consider the whole group as a unit, so we must wait until the last cyclist has finished passing.
