Pre-Trip Inspection Checklist
Item What to check Why it matters Notes
Cab and controls Check gauges, mirrors, horn, wipers, washer fluid, heater/defroster, warning lights, and seat belt. The pre-trip starts before the wheels move. Record warning lights by exact lamp or message.
Engine compartment Inspect oil, coolant, belts, hoses, visible leaks, wiring rub points, and fan area from a safe position. Heat, leaks, and belt problems can end a trip early. Do not open hot pressurized systems.
Brake check Observe air build, warning devices, parking brake function, and service brake response as required by your procedure. Brake concerns must be handled before public-road operation. Escalate abnormal pressure loss.
Trailer connection Inspect kingpin lock, landing gear, glad hands, air lines, electrical cord, ABS light, and trailer lights. Many pre-trip issues appear after trailer pickup. Photograph trailer damage before departure.
Load and body Check doors, seals, securement, straps, roof/floor visible condition, and placards when applicable. Equipment condition and cargo condition meet during pre-trip. Log shipper or yard defects clearly.

How Often to Use This Checklist

Use before each trip, after equipment swaps, and when picking up a trailer with unknown condition.

Common Mistakes

  • Checking boxes without writing mileage, unit number, defect notes, and follow-up status.
  • Treating a visual walkaround as a qualified mechanical inspection.
  • Skipping records for small defects that later become repeated repair issues.
  • Filing paper logs where drivers, dispatch, and maintenance cannot retrieve them quickly.

Records to Keep

  • Completed checklist with date, odometer, driver or inspector name, and unit number.
  • Defect correction notes, invoices, parts receipts, and photos when useful.
  • PM due mileage, next inspection target, and any out-of-service decision notes.
