Introduction
Annual DOT inspections are mandated by the Federal Motor Carrier Safety Administration (FMCSA) for all commercial motor vehicles, including Mack Trucks. This comprehensive checklist helps fleet managers and maintenance personnel ensure their Mack fleet meets all DOT requirements for annual inspections under 49 CFR Part 396.17.
The purpose of this DOT Annual Compliance Safety Checklist is to systematically evaluate all safety-critical systems and components on Mack Trucks, including the Anthem, Granite, Pinnacle, and TerraPro series. Completing this inspection helps maintain compliance with federal regulations, prevent roadside violations, enhance safety, and optimize vehicle performance. This checklist aligns with FMCSA requirements and Mack Trucks' manufacturer specifications.
Equipment Information
Pro Tips for DOT Annual Inspections
- Maintain Comprehensive Records: Keep detailed documentation of all inspections, repairs, and maintenance activities. The FMCSA requires that inspection reports be retained for at least 14 months from the date of the inspection.
- Use Certified Inspectors: Ensure that inspections are performed by qualified inspectors who meet the requirements of 49 CFR 396.19. This includes appropriate training, certification, and understanding of the FMCSA inspection criteria.
- Coordinate with Vehicle Usage: Schedule annual inspections during planned downtime to minimize disruption to operations. Consider conducting the inspection alongside other maintenance procedures to maximize efficiency.
- Pre-Inspection Preparation: Before the formal inspection, perform a preliminary check and address any obvious defects. This can prevent failed inspections and reduce the time needed for the formal inspection process.

Detailed Inspection Procedures
Follow these structured procedures to ensure a thorough DOT annual inspection of your Mack Truck fleet. These processes comply with Federal Motor Carrier Safety Administration (FMCSA) requirements under 49 CFR Part 396.
Brake Performance Testing
- Park on level surface and chock wheels
- Build air pressure to governor cutout (120-130 PSI)
- Turn off engine and release parking brake
- Apply and hold service brake pedal
- Monitor air pressure gauge for 1 minute (should not drop more than 3 PSI)
- Release and reapply brake - observe pressure drop when brakes applied
- Continue applying/releasing brake until pressure drops to 80 PSI
- Verify low air warning device activates between 55-60 PSI
- Continue reducing pressure to confirm spring brake activation (20-40 PSI)
Steering System Inspection
- With engine running, check steering wheel free play (not more than 10° before wheel movement)
- Examine power steering fluid level and condition
- Inspect steering gear box mounting and check for leaks
- Examine steering linkage for worn or damaged components
- Check for excessive play in steering knuckles
- Verify drag link and tie rod ends have minimal movement
- Ensure all steering components are properly secured
- Test steering through full range of motion
Coupling Device Inspection
- Check fifth wheel mounting brackets for cracks or breaks
- Verify all mounting bolts are tight and secure
- Inspect fifth wheel plate for cracks or damage
- Check for excessive movement between fifth wheel and frame
- Ensure fifth wheel jaws close properly around kingpin
- Verify release handle is in locked position
- Check kingpin engagement (no visible space between upper coupler and fifth wheel)
- For sliding fifth wheels, verify locking pins engage properly
Suspension System Inspection
- Examine frame rails and cross members for cracks or damage
- Inspect leaf springs for missing, cracked, or shifted leaves
- Check U-bolts and spring hangers for security and damage
- For air suspension, verify proper inflation and no leaks
- Inspect torque rods and bushings for wear or damage
- Check shock absorbers for leaks and secure mounting
- Verify axle alignment and tracking
- For lift axles, test proper operation of controls
