What safety precautions must the driver take when deploying a manual or powered wheelchair ramp at a bus stop?

1. Keep the bus creeping forward while the ramp extends, so the queue behind is not delayed
2. Extend the ramp before the doors have finished opening, to save time at the stop
3. Bring the bus to a complete stop, apply the parking brake, engage kneeling where fitted, keep the deployment area clear, and check the ramp rests securely on firm ground
4. Deploy the ramp onto the carriageway where the kerb is too high for it to reach
