Various objects can be repossessed, including boats and aircraft, but most repossession agencies focus on car repossession. The repo agent normally uses a tow truck or pickup truck with a special towing attachment called a boom. They also may obtain the key from the car owner. The agent must be careful however, because they cannot cause physical harm to the vehicle. Usually, the vehicle owner must be notified of a repossession. The repossession agent will find the car and check its information such as the Vehicle Identification Number (VIN) to make sure they have the right vehicle. If there is a match, they will attempt to hook up the car to the tow truck and tow it away or pick the lock and drive it away. However doing so does not absolve the repossession agent's requirement to be covered under an active insurance policy for the vehicle under the applicable criminal traffic laws. Thus, an agent who elects to do this may be subject to arrest for the violation of criminal traffic laws which apply to insurance requirements. The repo agents also cannot legally cross locked and enclosed storage spaces such as gates and garages. Repo agents also carry a massive amount of liability, so if they do not have all the proper insurances, the debtor will win a lawsuit.
