A pre-trip inspection is a thorough inspection of the truck completed before driving for the first time each day.
Federal and state laws require that drivers inspect their vehicles. Federal and state inspectors also may inspect your vehicles. If they judge a vehicle to be unsafe, they will put it “out of service” until it is repaired.
