The amount of storage is based on a daily fee, so that's the case. How are towing companies legally allowed to keep your car? Can I leave my car in the impounded parking lot and leave the trailer? During an investigation, a tow truck company can legally hold your vehicle for up to of 30 days. However, you'll have to pay for storage and tow truck costs from the time you arrive at the trailer yard until a court date is set or the police determine that they don't have enough evidence against you. If, after 30 days, no one paid these charges, ICBC can auction your vehicle.
Suppose that during this period no one pays for the seizure and towing costs that were initially paid at the time of being towed. If the full cost of all towing and storage fees isn't paid within 30 days, the tow truck company can sell any part or all of your vehicle at a public auction without the consent of the owner of the vehicle.
