A step-by-step commercial vehicle inspection checklist

Regular commercial vehicle inspections are crucial for road safety and staying compliant with regulations. A detailed inspection can catch issues early, helping to prevent costly repairs and reduce the risk of accidents. Here’s a step-by-step commercial vehicle inspection checklist to keep your fleet in top shape and road-ready. 

Step 1 – Exterior inspection

The first part of a commercial vehicle inspection checklist should focus on the exterior components, as these are vital for both safety and regulatory compliance.

Checklist

  • Lights and indicators: Check all headlights, brake lights, turn signals, and hazard lights to ensure they are working correctly and are free from cracks or moisture.
  • Mirrors and windshield: Inspect mirrors and ensure they provide a clear view. Check the windshield for any chips or cracks that could affect visibility.
  • Wipers: Test windshield wipers and fluid levels. Functioning wipers are essential for safe driving in adverse weather conditions.
  • Tires and wheels: Examine the tread depth, inflation level, and condition of each tire, including the spare. Look for signs of wear or any foreign objects lodged in the tires. Check that all wheel fasteners are secure.
  • Body and chassis: Look for signs of rust, dents, or other damage that may compromise the vehicle’s integrity.

Step 2 – Under the hood

The next step in the commercial vehicle inspection checklist focuses on the engine and essential under-the-hood components.

Checklist

  • Engine oil and fluids: Check levels of engine oil, coolant, power steering fluid and transmission fluid. Look also for any signs of leaks or contamination.
  • Belts and hoses: Inspect belts for cracks or signs of wear and hoses for leaks or damage. These components are critical to engine function.
  • Battery: Check the battery for corrosion and ensure it’s properly secured. Test the battery’s charge level if possible.
  • Air filter: Make sure the air filter is clean and free from debris, as a clogged filter can reduce engine performance.

Step 3 – Brake system inspection

The brake system is one of the most crucial parts of a commercial vehicle inspection checklist to ensure safety on the road.

Checklist

  • Brake pads and rotors: Inspect brake pads for wear and ensure rotors are smooth and free of damage.
  • Brake lines and hoses: Look for any leaks or cracks in brake lines and hoses.
  • Parking brake: Test the parking brake to ensure it holds the vehicle in place when engaged.
  • Air brake system (if applicable): For vehicles with an air brake system (Lorry Air brakes), check for audible air leaks and ensure that the system holds pressure.

Step 4 – Interior and cab inspection

The interior and driver controls are vital for the operator’s comfort and control over the vehicle.

Checklist:

  • Steering and suspension: Test steering for responsiveness and check for any unusual noises. Inspect the truck suspension for any signs of wear or damage.
  • Gauges and warning lights: Verify that all dashboard gauges and warning lights.
  • Seat belts: Test seat belts to make sure they function properly and show no signs of wear or fraying.
  • Driver comfort: Ensure that the seat is properly adjustable and mirrors can be positioned correctly for optimal visibility.

Step 5 – Underneath the vehicle

Checking the vehicle’s underside is often overlooked but essential for a comprehensive inspection.

Checklist:

  • Exhaust system: Inspect for rust, cracks, or holes in the exhaust system that could lead to harmful fumes.
  • Drivetrain: Check for any visible damage to the drive shaft, axle, or other drivetrain components.
  • Fuel tank and lines: Look for any signs of leaks or corrosion on the fuel tank and fuel lines. Ensure that all fasteners are secure and there are no visible cracks or damage.
