Vehicle Pre-Departure Checks and Roadworthiness
This domain tests the walk-around inspection and document check a bus driver must complete before the first trip and at the start of each shift. The exam rewards a systematic sequence and punishes the "it is only a short route" attitude.
The walk-around
- Tyres: correct pressure, no cuts, bulges or exposed cords, tread above the legal minimum, wheel nuts and indicators present.
- Lights: headlamps, dip and main beam, indicators, brake lights, hazard lights, side markers, reversing lights and number-plate lamp.
- Fluids and leaks: engine oil, coolant, brake fluid, windscreen washer, and no fresh pools under the bus.
- Brakes and steering: firm pedal, no air-brake hiss or warning buzzer, steering free play within limits.
- Body and access: doors close and latch, emergency exits open from inside, steps and handrails secure, mirrors adjusted.
- Safety equipment: fire extinguisher in date, first aid kit complete, warning triangles, jack and wheel spanner, reflective jacket.
- Documents: inspection certificate, PSV licence, insurance, route and fare chart.
Defect reporting
Any defect affecting safety grounds the bus. Record it in the defect book, report it to the operator, and do not depart until it is fixed and signed off.
Worked example
During the walk-around a driver finds one rear tyre with a deep sidewall cut and exposed cords. Pressure is correct and the other tyres are fine. The bus must not leave: a sidewall cut with exposed cords is a structural failure, not a wear item. The driver records and reports it, and the operator fits the spare or another compliant tyre before the trip.
Traps that cost marks
Checking only fuel and tyres; assuming a short route excuses a defect; treating an expired extinguisher as acceptable; and signing the defect book without actually doing the walk-around.
