Important things to check in a truck inspection
Before each trip, truck drivers must perform a thorough inspection to ensure the vehicle is safe and compliant with DOT regulations. Here’s a clear breakdown of all essential inspection points:
- Braking System: Check the brake pads, rotors, hoses, and brake fluid levels to ensure the entire braking system, including service brakes and emergency systems, is working properly.
- Coupling Devices: Inspect fifth wheels, pintle hooks, drawbars, and safety devices to ensure all connections between truck and trailer are secure and properly latched.
- Exhaust System: Look for any exhaust leaks under the cab or sleeper, damaged pipes, or components that could burn wiring or fuel lines.
- Fuel System: Check for visible fuel leaks, ensure fuel tank caps are present, and confirm tanks are securely mounted to prevent dislodgement.
- Lighting Devices: Verify that all headlights, tail lights, brake lights, indicators, and reflectors are present and working, including clearance and marker lights.
- Safe Loading: Ensure that cargo is securely loaded, properly blocked or braced, and that no loose parts or spare tires can fall onto the roadway.
- Steering Mechanism: Check steering components, including the wheel, column, pitman arm, drag links, and power steering system, for any looseness or damage.
- Suspension System: Inspect U-bolts, springs, hangers, and shock absorbers for cracks, missing parts, or any misalignment of the axle.
- Frame: Examine the frame and sliding subframe assemblies for cracks, bends, or any structural damage.
- Tires: Look for proper inflation, tread depth, sidewall damage, and irregular wear on all steering and power unit tires.
- Wheels and Rims: Inspect wheels for cracks, damaged rims, missing lugs, or loose fasteners that could lead to wheel separation.
- Windshield Glazing: Check for cracks, discoloration, or anything that obstructs the driver’s view and violates visibility standards.
- Windshield Wipers: Make sure windshield wipers are fully operational and not missing or damaged, which could impair visibility during rain or snow.
- Other Conditions: Identify and document any other issues that could impact safe operation, such as dashboard alerts or underbody damage.

- Level IV – Special Inspections: One-time checks done for specific studies or to investigate trends.
- Level V – Vehicle-Only Inspection: A full vehicle inspection conducted without the driver present, often at carrier facilities.
- Level VI – Enhanced Inspection for Radioactive Material: Applies to vehicles transporting transuranic waste or HRCQ radioactive materials. Includes special protocols and equipment checks.
- Level VII – Jurisdictional Mandated Inspection: Inspections mandated by local or state regulations for vehicles like school buses, limousines, or hotel shuttles.
- Level VIII – Electronic Inspection: A wireless inspection conducted while the vehicle is in motion, verifying driver and vehicle credentials electronically.
