Before driving, it is essential to inspect the interior of the cab, the engine compartment, the exterior of the vehicle, and the tires to ensure that the steering mechanism, tires, lighting signals, and braking devices are in good condition. Key external areas to check: tire pressure, windshield wipers, and fuel level. Internal and external inspection items: Walk around the vehicle: Inspect the condition of the body surface and the integrity of various components, checking for any leaks of oil, fluid, gas, or electricity. Clean the door and window glass, and the exterior of the vehicle to ensure that lighting devices and license plates are clear. Check whether the fuel tank's oil level, the radiator's coolant level, the crankcase's oil level, the brake fluid level (for hydraulic brake vehicles), and the battery's electrolyte level meet the requirements. Inspect the engine fan belt for signs of aging, cracking, or fraying, and ensure the tension is appropriate. Check the tire surface and pressure. Remove any debris or small stones lodged between the tires and treads. The tire pressure should meet the specified standards. Also, ensure the spare tire is properly secured. Check the flexibility of the steering mechanism and whether there is any looseness in the connections such as the tie rods. Inspect the wheel hub bearings and the kingpin for looseness, and ensure that the nuts on the tires, half-shafts, drive shafts, and leaf springs are tight. Examine the condition of all gauges and control devices inside the cab. Check if the lights, wipers, interior mirror, rearview mirror, door locks, and window cranks are complete and functional. Verify the condition of the steering wheel, clutch, brake pedal free travel, and parking brake. The free travel of the clutch and brake pedals should comply with normal specifications. Note that the steering wheel's free rotation should not exceed 30 degrees. After starting the engine, check for any unusual noises or odors and observe whether the gauges are functioning normally.
