You are driving in Queensland and approach a level (railway) crossing with flashing lights and ringing bells. What must you do?

1. Proceed quickly to beat the train if you can see the train is still far away
2. Slow down to 40 km/h and proceed with caution
3. Stop before the crossing and do not proceed until the lights stop flashing and bells stop ringing
4. Give way to the train only if the boom gate is down
