Inspect the following areas of a commercial vehicle for any of the following:

  • Tractor General
    • Altered interior lighting
    • Anything unusual in factory-built compartments
    • Unexplained new or shiny bolts and/or screws
    • Unusual scratches possibly made by screwdrivers, wrenches or similar clandestine entry tools
    • Signs of tampering, such as broken parts or bent sheet metal
  • Exterior
    • Lights not working
    • Compartments in frame rails (frame rails are normally open)
    • Cold or nonfunctioning exhaust pipe during operation
    • Battery box containing tampered-with batteries or disconnected battery wires
    • Storage compartments that contain unusual items
    • Magnetic GPS tracking devices attached on or under the tractor or trailer
  • Fuel and Air Tanks
    • Inconsistent/missing connections
  • Engine Compartment
