TRUCK RESEARCH

Semi Truck Inspection Checklist

Use this organized checklist to prepare questions and observations. It is not a substitute for a qualified professional inspection.

Documents and history

Confirm ownership information and compare records with the truck presented.

  • Maintenance and repair invoices
  • Configuration and component information
  • Mileage and engine-hour consistency
  • Known damage or major component replacements

Engine, cooling and emissions

Inspect for leaks, unusual noise, warning lights and incomplete service history.

  • Cold start and blow-by observations
  • Coolant condition and visible leaks
  • DOC, DPF, DEF and SCR history
  • Active, stored and cleared fault information

Drivetrain and running gear

Inspect transmission or clutch operation, differentials, suspension, steering, brakes, tires, wheels, frame and fifth wheel.

Cab, sleeper and road test

Check controls, HVAC, electrical accessories, restraints, visibility and road-test behaviour under appropriate conditions.

Use qualified help where appropriate

General research cannot confirm the condition, legality or suitability of a specific truck. Consider qualified mechanical, legal, financial and insurance advice for the purchase.
