Truck Pre-Delivery Inspection Checklist: New Fleet Units

A defensible truck PDI covers 7 functional sections plus a signature block. Spec verification: chassis serial matches purchase order, engine model and horsepower, transmission model and ratio, axle configuration and ratio, tyre size and load rating, body or trailer equipment, safety options as ordered. Transit damage: every panel photographed under natural light, paintwork checked for scratches and colour match, glass and mirrors intact, wheels and tyres undamaged, underbody visual for damage or leaks. Fluids and leaks: engine oil level, coolant, hydraulic reservoir if fitted, DEF, brake and PS fluid, no visible drips. Start and function: engine starts cleanly, no dashboard warnings, all lights and indicators functional, wipers, HVAC, ADAS, cameras, telematics displays. Test drive: acceleration, braking, steering, no unusual noises, cruise and retarder function, fault codes cleared post-drive. Documents and keys: registration or V5C or title, warranty book, owner's manual, 2 keys plus fuel-cap keys, outstanding recall status, OEM inspection certificate. Signatures and PDI report: inspector sign-off with time, dealer sign-off if applicable, defects flagged with photo, rework list agreed before acceptance, final Accept or Reject decision, PDF retained per asset. Plus a recall check (NHTSA in US, DVSA in UK) confirming all outstanding recalls resolved before delivery.

Because acceptance is the single moment that changes the warranty position of the asset. Before you sign delivery, defects belong to the OEM or dealer to resolve. Once you sign delivery, the truck is yours and every defect is your problem to prove pre-existed acceptance if you want warranty coverage. Manufacturers typically cover manufacturing defects for a defined period (often 30-90 days from delivery for the strongest coverage window, longer for full warranty), but proving a specific defect is a manufacturing issue rather than an operator or transport issue requires documentation from the PDI. Without pre-delivery photographs and inspection records, the manufacturer can and usually does argue that the defect resulted from operation or transport after delivery, weakening or defeating the warranty claim. The PDI record is also the baseline condition of the asset for its operational life — every future damage assessment, insurance claim, or resale evaluation traces back to it. The 45-90 minutes invested in a proper PDI on a Class 8 truck is small against the value of the asset and the size of the disputes that arise later without it.

Both, and neither substitutes for the other. The dealer PDI is the manufacturer or dealer's own inspection performed before the truck is offered to the customer for delivery, typically covering factory prep, missing items, obvious transit damage, and system function. The dealer PDI is the dealer's assurance that the truck is fit to hand over. The fleet PDI (also called acceptance inspection or handover inspection) is the buyer's own inspection performed at the point of delivery, before signing acceptance. This is where the buyer verifies the truck matches the purchase order, captures transit damage evidence, confirms function, and establishes the warranty baseline. The fleet PDI is the buyer's defensible record for future warranty disputes. Some fleets also commission an independent third-party inspector for high-value orders, particularly on custom-spec vocational vehicles or where the buyer lacks in-house technical expertise. Whoever performs the fleet PDI must be technically competent on the specific vehicle type, must document findings with photos and specifics, must identify any defects for pre-acceptance rework, and must formally sign off Accept or Reject before delivery is finalised.

A period specified by the engine and drivetrain manufacturer during which specific operational restrictions and additional maintenance apply to promote proper component seating and prevent premature wear. There is no universal break-in schedule — every OEM specifies its own, and confirming against the specific engine documentation is required. Typical break-in items include: moderate load in the first 500 to 1,000 miles to allow piston rings to seat correctly, avoiding excessive idle in the first ~100 hours because idle prevents cylinders from reaching the temperature required for ring seating, an initial oil change earlier than the standard service interval to remove metal fines from initial wear, and varied RPM and load through the first 5,000 to 10,000 miles rather than steady-state cruising. The single most-skipped break-in item is the wheel-nut retorque at 50 to 100 miles after delivery, then again at 500 miles — this is manufacturer-mandatory on almost every Class 8 truck and skipping it is one of the leading causes of wheel-off events on new vehicles. Confirm break-in against the specific truck's OEM guidance during commissioning and add the retorque as the first scheduled inspection in the asset's PM cadence.

Signing acceptance is the start of commissioning, not the end of the PDI. Six commissioning steps close the loop between acceptance signature and the first live shift. Asset record created: VIN, chassis serial, engine serial, spec sheet, purchase price, expected disposal date, cost centre entered in the fleet system. Baseline readings captured: delivery mileage, delivery engine hours, delivery fuel level — every future maintenance and cost calculation traces back to these numbers. PM schedule applied: OEM-specified PM intervals loaded per asset, starting with first oil change, wheel-nut retorque, break-in inspections, then standard intervals thereafter, with alerts firing automatically. Telematics and ELD commissioned: fleet telematics activated, ELD (US) or tachograph (UK/EU) commissioned, integration to fleet software confirmed, data flow verified before first shift. Driver familiarisation: assigned driver walked through cab, controls, ADAS features, HVAC, retarder, cruise, cameras. Owner's manual accessible in cab. Familiarisation record signed. Warranty registered: manufacturer warranty registered with delivery date and mileage baseline, extended and aftermarket warranties logged with expiry dates. A truck that clears all six commissioning steps in the first 48 hours enters service ready.
