Peterbilt Truck Pre-Trip Inspection Checklist
Introduction
A thorough pre-trip inspection is essential for Peterbilt truck safety, regulatory compliance, and optimal performance. This comprehensive checklist helps drivers identify potential issues before they lead to breakdowns, accidents, or DOT violations. Conducting a proper inspection before each trip is not only required by law but is also a critical safety practice that protects drivers, cargo, and other road users.
Peterbilt trucks are known for their quality and reliability, but even the best-engineered vehicles require consistent inspection and maintenance. This checklist covers all critical systems from brakes and tires to lights and fluids, helping drivers maintain their Peterbilt in peak condition while meeting all FMCSA requirements. Whether you're operating a Peterbilt 379, 389, 579, or any other model, this comprehensive pre-trip inspection checklist will help ensure your journey is safe and trouble-free.

Pro Tips for Effective Pre-Trip Inspections
- Establish a Routine: Develop a systematic inspection pattern and follow it consistently for every pre-trip to ensure nothing is missed.
- Allow Sufficient Time: A proper pre-trip inspection takes approximately 30-45 minutes. Plan accordingly, especially in adverse weather.
- Use All Senses: Look, listen, smell, and touch during your inspection. Unusual odors, sounds, or heat can indicate problems not visible to the eye.
- Document Everything: Record all defects, even minor ones. This creates a maintenance history and protects you legally.
- Weather Considerations: In extreme weather, pay special attention to systems affected by temperature (cooling system in heat, air brakes in cold).
- Remember Your Trailer: If pulling a trailer, it's part of your vehicle combination and requires the same thorough inspection as your tractor.

Key Pre-Trip Inspection Procedures
Follow these detailed procedures for critical parts of your pre-trip inspection on a Peterbilt truck. These procedures meet FMCSA requirements and help ensure your truck is safe and ready for operation.
Air Brake Test Procedure
- Build air pressure to governed cut-out (120-140 psi)
- Turn off engine, release parking brake, apply foot brake
- Hold for 1 minute and note pressure drop (should be 3 psi or less)
- Continue applying pressure for another minute (should be 4 psi or less combined)
- Start engine and rebuild to full pressure
- Fan brakes to reduce pressure, note when warning light/buzzer activates (55-60 psi)
- Continue to fan brakes, check spring brakes activate (20-40 psi)
- Rebuild pressure, test parking brake by gently trying to pull against it
Coupling Inspection Procedure
- Check fifth wheel for cracks and proper mounting
- Verify jaws are closed around kingpin
- Check release handle is in locked position
- Make sure trailer is sitting flat on fifth wheel (no gap)
- Check electrical and air connections are properly secured
- Verify air lines are not leaking
- Check trailer landing gear is fully raised
- Verify safety chains or cables are properly connected
Engine Start-Up Check
- Ensure transmission is in neutral and parking brake set
- Start engine and listen for unusual noises
- Check all gauges for proper readings
- Let engine idle to build air pressure
- Observe oil pressure gauge rises to normal range quickly
- Check temperature gauge begins to rise to normal range
- Verify voltmeter/ammeter shows proper charging
- Test dashboard controls (wipers, lights, defrost, etc.)
Tire & Wheel Inspection
- Check each tire for proper inflation with gauge
- Inspect tread depth with tread depth gauge
- Look for cuts, bulges, or signs of misalignment
- Check between dual tires for debris
- Check rims for cracks or welding repairs
- Verify all lug nuts are present and tight
- Check hub oil seals for leaks
- Look for signs of overheated brakes or hubs
