If your car has been towed, you should have received the tow yard information from the police officer at the scene. Contact the tow company immediately and advise them of the at-fault driver’s insurance information.
Find out from the towing company what the fees owed are so far and what the daily cost is.
Until and unless the at-fault driver accepts 100% liability for the accident, towing and storage costs are your responsibility. Thus, you may want to consider having the car taken to a cheaper location. Note, however, that you will also need to pay for it to be taken somewhere else.
