First, look in the area where you parked for a tow-away zone sign. If you locate a sign it should tell you the towing company's name and phone number. Give the call taker your vehicle description and the location your vehicle was towed from. The call taker should be able to assist you with locating your vehicle. This type of towing occurs on posted property, such as apartment complexes and private business parking lots.
Homeowners can also call a tow company if an unauthorized vehicle is on their property.
When your vehicle is towed in this manner it is not a police matter, it is a civil matter, and the fees are set by the company that towed your vehicle.
