Yes the police can impound the vehicle for 30 days because the driver had a suspend license. Your mom could have been charged with a misdemeanor as well for letting someone drive her vehicle if she knew that person’s license was suspended. It is never a good idea to lend someone your car especially if their license is suspended.

Your assumption is incorrect. A car can be impounded if the driver has a suspended license. Call wtach commander of impounding police agency about getting car released. You must deal with citation for suspended license- and reason behind it. Get an attorney.
