Vehicle Inspection and Pre-Trip Checks for Passenger Vehicles
Two layers of inspection
Pre-trip inspection on a passenger vehicle has a general layer and a bus-specific layer, and the exam tests both. The general layer is the familiar walk-around: engine compartment (fluid levels, belts, hoses, power steering), lights and reflectors, tires/wheels/rims, brake and suspension components, and the in-cab checks (gauges, horn, wipers, seat belt, parking brake, service brake). The bus-specific layer is where most questions cluster: emergency exits - side windows, roof hatches, and rear door - must open freely from both inside and out; the fire extinguisher must be charged, mounted, and within the driver's reach; the first aid kit must be sealed and complete; three reflective triangles must be aboard; seats must be securely fastened with no broken frames or torn cushions; the aisle and stairwell must be clear; handrails and stanchions must be secure; entry and exit doors must operate smoothly; and the standee line must be plainly marked.
Traps the writers build in
- "Once every 24 hours" is not the right answer for a bus. You inspect before each trip, and again whenever a defect is reported or a condition changes.
- Distractors often smuggle in equipment a bus does not carry, such as a trailer breakaway cable or glad hands.
- The standee line is not decoration: no passenger may stand forward of it, because that space belongs to the driver's view and reach.
Rule of thumb: if a passenger could touch it, open it, or trip over it, expect the examiner to ask about it. Walk the bus the way a passenger would experience it, then walk it the way a mechanic would.
