Can you drive another persons car if you have a DUI conviction?

Since you have DUI I suspect that your licence was also pulled so you now have a suspended licence. To drive another's car with a suspended licence is not only illegal but rather a bum deal for the person who owns the car. If you had an accident they would be libel for the damages and could loose insurance and the car because you were the driver. I wouldn't loan you a car for the above reasons.
