If your license plates are impounded due to a DWI, and you are the registered owner of the vehicle, your license plates will be impounded for at least 1 year. If, at the time that 1 year has elapsed, you do not have a valid license (either fully valid or on ignition interlock) that plate impoundment will continue until you get that taken care of. If the vehicle is not registered in the offenders name, the license plates will be impounded for 1 year only. If you are required to have whiskey plates due to a DWI/DUI arrest, call the experienced attorneys at Gerald Miller, P.A. for a free consultation.
