Pre-trip/Post-trip Inspections: Required checks to ensure roadworthiness

1. Pre-Trip Inspection

A pre-trip inspection is done before the driver starts a trip to ensure the vehicle is safe and legally compliant.

Key Steps

  1. Vehicle Overview

    • Walk around the vehicle to check for obvious damage, leaks, or loose parts.

    • Check tires for proper inflation, tread depth, and damage.

    • Ensure lights, reflectors, and license plates are clean and visible.

  2. Engine Compartment

    • Check engine oil, coolant, power steering, and windshield washer fluid.

    • Inspect belts, hoses, and fuel lines for wear or leaks.

    • Ensure battery connections are tight and secure.

  3. Cab Check

    • Verify horn, wipers, mirrors, and gauges work properly.

    • Check seat belts for wear and functionality.

    • Review driver logs, registration, insurance, and required permits.

  4. Brake System

    • Inspect air lines, hoses, and connections.

    • Test parking brakes and service brakes for proper function.

    • Check brake pads or shoes if visible.

  5. Lights & Electrical

    • Turn on headlights, brake lights, turn signals, hazard lights.

    • Test dashboard warning lights and gauges.

  6. Trailer (if applicable)

    • Check coupling devices (fifth wheel, kingpin) and locks.

    • Inspect trailer tires, brakes, lights, and reflective tape.

    • Make sure cargo is properly secured.

  7. Safety Equipment

    • Ensure fire extinguisher, triangles, spare fuses, and PPE are on board.

2. Post-Trip Inspection

A post-trip inspection is done after the trip to identify issues that occurred while driving and report them to maintenance.

Key Steps

  1. Walk-Around Check

    • Look for leaks, tire damage, and vehicle damage incurred during the trip.

    • Inspect trailer and cargo for shifting or damage.

  2. Brakes & Suspension

    • Look for air leaks, worn components, or abnormal wear.

  3. Lights & Reflectors

    • Verify that all lights still function after the trip.

  4. Fluid Levels & Leaks

    • Inspect engine, transmission, coolant, and other fluids for leaks or low levels.

  5. Reporting

    • Complete a Driver Vehicle Inspection Report (DVIR) noting any defects.

    • Submit DVIR to maintenance or fleet management promptly.

3. Regulatory Notes

  • FMCSA Requirement: Every commercial driver must conduct a pre-trip inspection before driving and a post-trip inspection at the end of their shift.

  • Oregon Compliance: Oregon DOT follows federal FMCSA rules and may perform roadside inspections; DVIRs must be accurate and retained.

✅ Tip: Consistently performing thorough pre- and post-trip inspections reduces accidents, prevents costly repairs, and keeps drivers legally compliant.
