Wheelchair Lift Defect on a Substitute Route
A substitute driver, Ms. Ortiz, is assigned a 28-passenger school bus with a wheelchair lift and two students who use wheelchairs. During the pre-trip, she deploys the lift: the audible warning does not sound, and the platform moves slowly but smoothly. The weather is raining, and the platform is wet. One student's wheelchair has no lap belt; the bus has a four-point tie-down and a separate lap/shoulder belt. The route includes a 15-minute stop at a school with no aide available. Ortiz has not driven this bus before. The regular driver is absent, and dispatch tells her “the lift warning has been like that for a week; just go.” The lift's manual backup pump is in the side compartment; the bus has a rear emergency door.
1. Should Ortiz accept the bus and use the lift? Explain the safety and compliance reasoning.

She should not accept the bus as ready for service. The audible warning is a safety interlock; if it does not sound, the lift may be defective, and slow movement suggests a hydraulic or power problem. Rain and a wet platform increase slip risk. Dispatch's “it's been like that for a week” is pressure, not a repair.
She should do a full lift inspection, check the manual backup procedure, and report the defect. Unless a qualified mechanic clears it or another bus is provided, she should refuse the lift and the route. Using it with students aboard creates a foreseeable hazard and can expose her and the district to liability.
2. How should Ortiz secure the student whose wheelchair has no lap belt?
Read the worked answer
Secure the wheelchair with the four-point tie-down at the frame, not the wheels or armrests. Apply the wheelchair brakes. Use the bus's separate lap/shoulder belt across the student's pelvis and shoulder-not the wheelchair's missing belt. The lap belt must be low and tight; the shoulder belt should not cross the neck. Check that the tie-down straps are tight and that the student can breathe comfortably.
The student's wheelchair lacks a lap belt, so the bus belt is essential. Do not rely on the tie-downs alone to restrain the student.
3. If the lift fails at a stop with a student aboard, what should she do?
Read the worked answer
Keep the student calm and do not improvise a manual lift unless there is an immediate emergency such as fire. Use the manual backup pump only if trained and it is safe, and call dispatch for another accessible bus. If evacuation is necessary, use the rear emergency door and trained assistance; a wheelchair user should not be carried by untrained people except to escape imminent danger.
Document the failure and remove the bus from service. The decision should be based on the actual hazard, not on completing the route.
