You'll check VIN plates, registration, insurance, and placards for heavy or hazardous loads, including weight and size labels.
Locating and reading VIN plates and stickersVerifying registration and insurance papersWeight, dimension, and capacity placardsSpecial placards for hazardous materialsStoring documents for roadside inspectionLesson 6Towing vehicle pre-trip checks: tyres, tread depth, inflation, spare tyre conditionThis section covers pre-trip checks for the tow vehicle. You'll inspect tyre condition, tread depth, pressure, and spare, ensuring the vehicle handles the trailer load.

You'll test service and parking brakes, trailer brake controller, and do low-speed stops to ensure balanced, straight braking.
Checking pedal feel and brake warning lightsParking brake hold test on a gradeAdjusting trailer brake controller gainTesting trailer brakes at low speedRecognizing brake fade and imbalanceLesson 8Fluid and engine checks: oil, coolant, transmission fluid, power steering, windscreen washerThis section details engine bay and fluid checks before towing. You'll verify oil, coolant, transmission fluid, power steering, and washer fluid, spotting leaks or overheating risks under load.

You'll do a walk-around, check key items, and record with forms and photos for maintenance and compliance.
Designing a step‑by‑step walk‑aroundUsing printed or digital checklist formsTaking photos of key inspection pointsRecording defects and corrective actionsStoring records for audits and resaleLesson 11Simple load-rating calculation examples: tongue weight percentage, gross trailer weight vs tow vehicle capacityThis section gives simple load calculations for towing. You'll calculate tongue weight percentage, compare trailer weight to tow capacity, using real examples to stay within limits.
