What safety precautions must the driver take when stopping at a passenger station or intermediate stop to allow passengers to board and alight?

1. Bring vehicle to complete stop, engage parking brake, activate hazard flashers / right indicator, ensure curbside alignment, and only then open passenger doors
2. Open passenger doors while the bus is still rolling at 10 km/h to speed up boarding
3. Park in the active left-hand overtaking lane and wave passengers across the road
4. Keep the bus in gear with the accelerator depressed while passengers board
