In general, you forget that you had an obligation to perform. However, the case is totally different from the agreement reached. As the owner of the vehicle, you want to know that you are protected from towing and that you are legally on solid ground with a rental document for regular parking in your place. Yes, it is possible. However, it is best to describe in your lease the events that could lead to towing their car or truck. You should also add information about who is responsible for these costs. In most areas, it is enough to show the lease to the towing company to issue the towing authorization. You can also include contact information for the towing company in your contract. If your parking lot looks like a public parking lot, you should consider installing signs indicating that it is only a private parking lot.
