Gauges and Controls

First, check all the gauges and controls in the truck. Make sure every gauge, like the fuel and temperature gauges, is working right. If something looks off, it might mean a problem with the truck. For example, if the temperature gauge is too high, the engine might be too hot.

It’s super important to check all the safety equipment. Look for fire extinguishers and emergency triangles. These items help keep the driver and others safe in case of an emergency. Make sure they are in good condition and easy to reach.

In-Cab Items

Seat Belts

Always check the seat belts. Make sure they are not worn out or broken. The seat belts should click into place and hold tight. This keeps the driver safe if there’s an accident.


Adjust the mirrors to make sure you can see clearly around the truck. Properly adjusted mirrors help avoid accidents and keep everyone safe on the road.

Safe Start Procedure

Engine Start

When starting the engine, listen for any unusual noises. A smooth start means everything is probably okay. But if you hear strange sounds, like knocks or rattles, there might be something wrong.

Brake Test

Perform a 5-step brake test to make sure the brakes work properly. This is crucial for stopping the truck safely. If the brakes don’t feel right, do not drive the truck.

Trailer Inspection

Fifth Wheel Area

Inspect the coupling system to make sure it is secure and not worn out. Check the bolts and nuts for any looseness. If you see any cuts or leaks, make sure to report them immediately.

Look for any damage on the side of the trailer. Ensure that all lights are working properly and the reflective tape is in good condition. This helps other drivers see your vehicle better, especially at night.

Rear of Trailer

Make sure the doors at the rear are secure. Check if the lights are operational. This is crucial for safety when you are on the road.

Trailer Suspension

Axle and Suspension

Check the axle and suspension for proper alignment. Ensure everything is securely mounted. Look for any signs of wearor damage. If the suspension is not in good condition, it could make the trip unsafe.

By following these steps, you can ensure your truck and trailer are in good shape for your next trip. Remember, a proper pre-trip inspection helps keep everyone safe on the road!
