DOT Annual Inspection Preparation Checklist
Introduction
The Department of Transportation (DOT) Annual Inspection is a mandatory requirement under 49 CFR 396.17 for all commercial motor vehicles operating in interstate commerce. This comprehensive inspection ensures that vehicles meet federal safety standards and are maintained in a condition that prevents mechanical breakdowns and safety hazards.
This detailed preparation checklist helps fleet managers and maintenance personnel thoroughly prepare vehicles for their annual DOT inspection, reducing the risk of violations, fines, and out-of-service orders. Proper preparation not only ensures compliance but also promotes safety, extends vehicle lifespan, and reduces unexpected maintenance costs.

Pro Tips for DOT Annual Inspection Success
- Schedule Strategically: Plan your annual inspection 30-45 days before the current inspection expires to allow time for any necessary repairs and re-inspections.
- Pre-Inspection Maintenance: Perform a thorough preventive maintenance service 2-3 weeks before the inspection to identify and correct issues that might cause inspection failures.
- Document Everything: Keep detailed maintenance records for at least 14 months. Organized documentation demonstrates your commitment to compliance and can help prove that required maintenance has been performed.
- Interior Cleaning: Clean the cab interior thoroughly before inspection. This shows attention to detail and ensures no important components are obscured by dirt or debris.
- Understand Inspector Focus Areas: Experienced inspectors often have "hot spots" they check first. Common focus areas include brake adjustment, tire condition, lights, and steering components.

Key Inspection Preparation Procedures
Follow these procedures to thoroughly prepare your vehicle for DOT annual inspection, focusing on common failure points and inspection priorities.
Brake Adjustment Procedure
- Position vehicle on level surface and chock wheels
- Release spring brakes and verify air system is at operating pressure
- Measure pushrod travel at 90-100 psi application pressure
- Compare measurements to specification chart for chamber type/size
- Adjust brakes that exceed 80% of adjustment limit
- Verify adjustment holds after several brake applications
- Document all measurements and adjustments performed
Lighting System Check
- Clean all light lenses thoroughly before inspection
- Check all lights with a partner or using reflection method
- Verify proper function of high/low beams, turn signals, brake lights
- Inspect all marker lights and reflectors for proper operation
- Check wiring harnesses for secure connections and chafing
- Replace any cracked or fogged lenses
- Verify all lights are securely mounted and properly aimed
Air Brake System Test
- Build system to governor cutout (typically 120-140 psi)
- Shut off engine and apply service brake firmly
- Monitor air gauge for one minute (loss should not exceed 3-4 psi)
- Start engine and rebuild pressure to governor cutout
- Fan brakes to reduce pressure and verify low air warning at 55-75 psi
- Continue reducing pressure to verify spring brake activation (20-40 psi)
- Check air dryer function and drain all air tanks
Suspension & Frame Inspection
- Inspect frame rails thoroughly using flashlight
- Check all spring leaves for cracks or shifts
- Verify all U-bolts are tight and intact
- Inspect shock absorbers for leaks and secure mounting
- Check torque arms and bushings for excessive wear
- Inspect air suspension components for proper inflation and leaks
- Look for any illegal welds or repairs on frame components
