Vehicle Inspection and Pre-Trip Procedures
This domain tests the pre-trip inspection and school-bus-specific equipment checks a driver must perform before a route, plus post-trip procedures. The exam expects a logical inspection sequence and recognition of defects that make the bus unsafe.
Core inspection content
- Engine compartment: fluid levels, belts, hoses, leaks, steering, and brake components.
- Exterior: tires, wheels, lug nuts, lights, reflectors, mirrors, service door, and emergency exits.
- School bus equipment: stop arm extends fully, red warning lights flash, crossing gate operates, and the driver can see the danger zones in the mirrors.
- Interior: seats, seat belts, fire extinguisher, first aid kit, emergency triangles, and aisle clearance.
- Air brake check when equipped: static leak test, applied leak test, low-pressure warning, and spring brake operation.
- Post-trip: walk to the rear of the bus and check every seat for sleeping students, secure the bus, and report defects.
Worked example
During a pre-trip inspection, the stop arm extends only halfway and the red lights do not flash. The driver should not start the route. The stop arm and warning lights are safety-critical school bus equipment; the driver should report the defect and use another bus. A defect that affects student protection is not treated as a minor issue to fix later.
Traps that cost marks
- Checking only the headlights and tires and skipping emergency exits and the stop arm.
- Forgetting to test the crossing gate and warning lights with the ignition in the correct position.
- Rushing the air-brake check or skipping the low-pressure warning test.
- Completing the route but skipping the post-trip walk-through to the rear.
- Driving a bus with a known safety defect instead of reporting it.
