Pre-Trip Inspection and Defect Reporting
What the exam tests
This domain tests the daily walk-around inspection and the reporting chain. You must know what to check, what makes a vehicle unfit for service and how to record a defect.
Core rules
- Check tyres for pressure, cuts, bulges, exposed cords and tread depth; check wheel nuts and dual spacing.
- Test lights, indicators, horn, mirrors, wipers and washers.
- Check engine oil, coolant, brake fluid where fitted, fuel and AdBlue if used; look for leaks under the vehicle.
- Check load security, curtains, doors and tail-lift stowage.
- Test the brakes and air pressure build-up; confirm the low-pressure warning works.
- Record defects in the defect log and report them before driving if they affect safety.
Worked example
A driver finds a rear tyre with a deep cut exposing white cord. The tyre still holds pressure. The correct decision is to report the vehicle as unfit and not drive it. The reasoning: exposed cords mean the tyre structure is damaged and it can fail at speed; pressure alone does not prove roadworthiness. The defect goes in the log, the supervisor is informed, and the vehicle stays parked until the tyre is replaced.
Traps
Do not treat a defect as acceptable because the vehicle still moves. Do not sign a blank defect sheet. Do not rely on the previous driver's inspection; you are responsible for the vehicle you take out.
