What is the first step a driver should take when a passenger in a wheelchair is waiting to board a Wheelchair Accessible Bus (WAB)?

1. Instruct the passenger to stand up and walk onto the bus
2. Deploy the ramp immediately without checking the kerb distance
3. Align the bus closely and parallel to the kerb, lower the bus suspension (kneel), and activate hazard lights
4. Ask other passengers to carry the wheelchair onboard
