There has been increased chatter that terrorists may try to use cars or trucks carrying improvised explosive devices to carry out mass-casualty attacks.

• Vehicles unusually or illegally parked or unusual vehicles parked in authorized areas.
• Missing, mismatched, or expired licensen plates, registration stickers or inspection decals.
• Missing or altered vehicle identification number.
• Vehicle laden beyond normal capacity, in weight or amount of cargo.
• Cargo concealed or obscured by a tarp or tinted window.
• Interior parts missing.
• Interior that appears tampered with or unusually altered (misaligned panels, missing screws or fasteners, missing or ill-fitting seats).
• Aftermarket products, which may be used to conceal IEDs or related components.
