Daily Safety Inspection Checklist for Mack Trucks
Introduction
Daily safety inspections are critical to maintaining the operational safety, regulatory compliance, and optimal performance of your Mack truck fleet. This comprehensive checklist provides a systematic approach for drivers and maintenance personnel to evaluate key safety components before each day's operation.
Performing this daily safety inspection helps prevent accidents, reduce roadside breakdowns, minimize unexpected downtime, and ensure compliance with DOT regulations. Regular inspection of critical safety systems such as brakes, steering, tires, lights, and fluid levels can identify potential issues before they develop into major problems or safety hazards. This checklist is designed specifically for Mack trucks and incorporates manufacturer recommendations alongside regulatory requirements to keep your fleet operating safely and efficiently.
Vehicle & Operator Information
Pro Tips for Effective Mack Truck Safety Inspections
- Use the Mack Co-Pilot Display: On newer Mack models, utilize the Co-Pilot digital display to check diagnostic trouble codes (DTCs) at the beginning of your inspection. This can help identify electronic system issues that may not be visible during a physical inspection.
- Check Brake Stroke Indicators: Mack trucks equipped with automatic slack adjusters often have visual brake stroke indicators. Look for the alignment marks on the slack adjuster and bracket to quickly verify proper brake adjustment.
- MP Engine Daily Care: For Mack trucks with MP engines, pay special attention to the coolant level, as these engines are particularly sensitive to coolant issues. Check for coolant leaks around the EGR cooler and DPF connections where issues commonly develop.
- mDRIVE Transmission Check: For trucks with mDRIVE transmissions, verify the transmission display shows no active codes and check for fluid leaks around the clutch actuator area, a common issue point.

Key Safety Inspection Procedures
Follow these specific procedures to thoroughly inspect critical safety systems on your Mack truck. These structured approaches help ensure proper evaluation of components that directly impact operational safety.
Brake Adjustment Verification
- Block wheels and release spring brakes
- Mark push rod at brake chamber face with brakes released
- Have assistant apply full brake application (90+ psi)
- Measure push rod travel from mark to chamber face
- Verify within limits (typically max 2" for standard stroke chambers)
- Check adjustment on all brake chambers
Air System Leak Check
- Build air pressure to governor cutout (120-130 psi)
- Turn engine off and release parking brake
- Apply service brake fully and hold for 1 minute
- Monitor air gauge for pressure drop (max 3 psi/minute single vehicle)
- Release service brake and monitor for additional leaks
- Listen for audible air leaks around system components
Steering System Inspection
- Check steering wheel free play (max 10 degrees)
- With engine running, turn steering wheel back and forth
- Have assistant observe steering linkage for movement
- Check pitman arm, drag link, and tie rod for looseness
- Inspect steering gear box mounting and leaks
- Verify power steering fluid level and condition
Fifth Wheel Coupling Check
- Verify fifth wheel is securely mounted to frame
- Check for proper lubrication of fifth wheel plate
- Ensure locking jaws fully engage kingpin
- Verify release handle is in locked position
- Inspect for gap between trailer apron and fifth wheel
- Tug test: apply trailer brakes and attempt to pull forward gently
