Legally it is the owner. Morally it would be whoever caused it to be impounded in the first place.
The vehicle's owner .
the owner of the car with insurance will be responsible
It is my understanding that the car owner's insurance pays for the person who was hit. The driver's insurance is responsible for the car he/she was driving.
Both
Both the driver and owner of vehicle are responsible. The injured party would sue you both.
If they are stopped your car could be impounded. If they get into an accident you are responsible for damages of your car and the other person's car. Not worth letting them drive.
The Driver is the primarily responsible party, however, Both can be held liable depending on the circumstances.
Yes, if your car is related in an accident or crime it can be impounded for being part of it.
No. A co-owner is one of the owners. If he's an owner it is obviously not theft. If you file a theft report against an owner you could be jailed for filing a false police report. Also, if the driver is stopped the car will be impounded resulting in costly fees and fines.
NO. A property owner is not responsible for acts of nature.
The car owner is responsible.
No. Car insurance is insurance on the car not insurance on the driver.
