A bus displays a 'Give Way' sign on its back right-hand side and is indicating to enter traffic from a bus stop. The speed limit is 60 km/h. What must you do?

1. Give way to the bus only if the speed limit is under 50 km/h
2. Give way to the bus because the speed limit is 70 km/h or less
3. Proceed past the bus — it must wait for a gap in traffic
4. Flash your lights to tell the bus driver to wait
