Pre-trip inspections for trucks are important routines to ensure safety and regulatory compliance. They follow a logical sequence that usually takes about 15 minutes.
Below is the updated step-by-step guide for 2025:
1. General external tour (360 degrees)
Leveling: Check if the truck is leaning to one side, which could indicate a suspension or tire problem.
Leaks: Inspect the underside of the chassis for drops of oil, fuel, coolant, or hydraulic fluid.
Tires: Check pressure, tread depth (without “chipotes” or stones), and tightness of bolts (bolts).
Hitch System: Make sure the fifth wheel and trailer hoses are properly connected and secured.
2. Engine compartment
This check should be carried out with the engine off and cold:
Fluids: Check the levels of engine oil, coolant (antifreeze), power steering fluid, brake fluid and windshield wiper fluid.
Mechanical components: Check the condition of the belts, hoses (no cracks or leaks), and battery.
Covers: Make sure all covers (radiator, oil) are closed and that the oil bayonet is securely attached.
3. Cabin and internal controls
Documentation: Confirm that you have maintenance records, insurance and a current technical inspection.
Dashboard and Gauges: When starting the engine, check that the oil pressure and oil tension are correct.
Safety and visibility: Adjust the mirrors, test the horn (electric and pneumatic), clean the windshield and check the condition of the seat belts.
4. Light and brake test
Lights: Turn on and physically check all lights: high beam, low beam, turn signals, parking lights, brake lights, and backup lights.
Braking System: If using air brakes, drain the moisture containers and ensure the pressure reaches 120 PSI. Test the pedal for audible leaks.
5. Documentation and Reporting (DVIR)
Recordkeeping: Document findings in the Daily Vehicle Inspection Report (DVIR). If the truck has a refrigeration unit, also certify its condition.
New equipment (2025): By the end of 2025, it will be mandatory in various jurisdictions to verify that approved GPS devices and monitoring systems are operational and providing accurate reports.
