You approach an intersection where you face a green light but want to turn right. Oncoming vehicles are also travelling on a green light. What must you do?

1. Proceed — you have right of way because your light is green
2. Wait in the intersection until there is a safe gap, then turn right, giving way to all oncoming vehicles
3. Flash your right indicator and oncoming vehicles must slow to let you turn
4. Wait until the amber light to turn right more safely
