Following a commercial truck maintenance checklist is a smart idea if you want to avoid extensive repairs and expensive downtime. It’s a key part of your preventive maintenance program, and it helps ensure your new trucks or used trucks are in good enough condition to pass their CVSA inspections. Read on for everything you need to know.

Why Follow Commercial Truck Maintenance?

The United States Department of Transportation (DOT) tells us there are over 500,000 truck accidents a year. Many of those are due to the driver of a passenger car, but the condition of trucks is also an essential factor and a big reason why truck company fleets and driver-owned commercial trucks should be properly maintained through a commercial truck maintenance checklist.

Beyond avoiding accidents, you’ll also catch any minor problems before they’re allowed to develop into major issues. You can then schedule work at your convenience to avoid breakdowns or the need for serious repair work in the future.

FMCSA Commercial Truck Maintenance Checklist

A pre-trip and post-trip inspection should be followed when you’re dealing with commercial trucks, and the Federal Motor Carrier Safety Administration (FMCSA) has created its own for you to follow. Their pre-trip maintenance checklist covers:

  • Tires: The FMCSA tells us tires account for around one-third of total maintenance costs, so check air pressure and tread.
  • Fluids: Look for fluid leakage under your truck, then check coolant, oil, fuel, and antifreeze levels before setting off. You should also turn on the ignition to examine oil pressure, temperature, and air pressure gauges.
  • Electrical System and Wiring: Check all lights, including the warning lights, clearance lights, flashers, turn signals, and brake lights. Review your electrical components for anything worn or loose.
  • Brakes: Check parking and standard brakes for the proper amount of lining. Check for leaks in the air pressure system.
