Introduction
Pre-trip truck inspections are a critical component of commercial vehicle safety and DOT compliance. This comprehensive checklist provides drivers and fleet operators with a systematic approach to conducting thorough pre-trip inspections that meet Department of Transportation requirements. A proper pre-trip inspection not only ensures regulatory compliance but also prevents roadside violations, reduces accident risks, and minimizes costly vehicle breakdowns during transport operations.
Following this DOT-compliant pre-trip checklist helps drivers identify potential safety hazards before hitting the road, maintain their Commercial Driver's License (CDL) standing, and protect their carrier's safety rating. This 10-point walkaround inspection checklist covers all major vehicle systems as required by Federal Motor Carrier Safety Administration (FMCSA) regulations 49 CFR 396.13 and 396.3, ensuring complete compliance with federal trucking inspection standards.

Pro Tips for DOT-Compliant Pre-Trip Inspections
- Allow Adequate Time: A thorough pre-trip inspection typically takes 15-20 minutes. Never rush through the checklist as missing defects can result in violations, fines, or accidents.
- Document Everything: Record all defects found during inspection, even minor ones. This documentation protects you during DOT audits and roadside inspections.
- Use the Same Routine: Develop a consistent inspection pattern (clockwise or counter-clockwise) to ensure nothing is missed during your walkaround.
- Check Previous DVIRs: Review the last Driver Vehicle Inspection Report to verify that reported defects have been properly repaired before operation.
Point 1: Engine Compartment
Point 2: Cab/Driver Area
Point 3: Front of Vehicle
Point 4: Left Side of Vehicle
Point 5: Rear of Vehicle

DOT Pre-Trip Inspection Procedures
Follow these systematic procedures to ensure your pre-trip inspection meets all DOT requirements and identifies potential safety issues before they become violations or breakdowns.
Air Brake Check Procedure
- Build air pressure to governor cutoff (120-140 psi)
- Turn engine off and release parking brake
- Apply and release service brakes to check air loss
- Air loss should not exceed 3 psi/minute (single) or 4 psi/minute (combination)
- Apply service brake and hold for one minute
- Check that low air warning activates between 55-75 psi
Light Check Sequence
- Turn on all exterior lights
- Walk around vehicle checking each light
- Have partner apply brakes to check brake lights
- Test turn signals in both directions
- Verify 4-way flashers operate all signals
- Check high beam indicator on dash
In-Cab Brake Test
- Test parking brake by gently pulling against it
- Test service brakes at 5 mph for stopping power
- Check for brake pull to either side
- Listen for unusual noises or air leaks
- Ensure brake pedal doesn't go to floor
- Verify emergency/spring brakes apply automatically
Coupling System Check
- Check fifth wheel is tilted properly for coupling
- Verify no damaged or missing parts
- Ensure platform is firmly mounted to frame
- Check that locking mechanism is open
- Confirm adequate grease on fifth wheel plate
- Test that jaw lock is properly engaged after coupling
