When giving way to a bus that has signalled and is merging back into traffic in the ACT, what does the driver need to do?

1. Always give way to any bus in a bus zone
2. Give way to a bus displaying an indicator showing it is leaving a bus stop, if travelling at 60 km/h or less in the zone
3. Buses have right of way only on dedicated bus lanes
4. Flash your headlights to acknowledge the bus's signal
