A traffic image shows a priority road sign for your route, but you are turning right across a cycle path with a cyclist approaching from behind on your right. What controls your action?

1. Your priority-road status does not remove the need to check the blind spot and avoid cutting off the cyclist
2. Priority road means every cyclist must yield to the truck
3. The cyclist is irrelevant once your signal is on
4. A heavy vehicle may turn first because stopping is difficult
