2.1 – Vehicle Inspection

2.1.1 – Why Inspect

A Vehicle inspection will help you find problems that could cause a crash or breakdown. Safety is the most important reason you inspect your vehicle, safety for yourself and for other road users.

A vehicle defect found during an inspection could save you problems later. You could have a breakdown on the road that will cost time and dollars, or even worse, a crash caused by the defect.

Federal and state laws require that drivers inspect their vehicles. Federal and state inspectors also may inspect your vehicles. If they judge the vehicle to be unsafe, they will put it "out of service" until it is fixed.

2.1.2 – Types of Vehicle Inspection

Note: Each pre-trip inspection test is a time-limited test. The maximum time allowed to complete the test is thirty minutes.

During a trip you should:

Watch gauges for signs of trouble.
Use your senses to check for problems (look, listen, smell, feel).
Check critical items when you stop:
- Tires, wheels and rims.
- Brakes.
- Lights and reflectors.
- Brake and electrical connections to trailer.
- Trailer coupling devices.
- Cargo securement devices.

After-trip Inspection and Report

You should do an after-trip inspection at the end of the trip, the day, or the tour of duty on each vehicle you operated. It may include filling out a vehicle condition report listing any problems you find. The inspection report helps a motor carrier know when the vehicle needs repairs.

They will require you to transfer the load to another truck
They will tow it to the nearest holding lot
They will require the driver to take a 30 minute safety course before driving again

Federal and state inspectors also may inspect your vehicle. If they judge the vehicle to be unsafe, they will put it "out of service" until it is fixed.

Being placed "out of service" can happen if inspectors decide the vehicle is unsafe. They can also place a driver out of service if they deem the driver unfit to drive or if the driver can not drive legally.
