You have two separate things against you when you are arrested for DUI, the DMV and the Court. If the prosecuting agency never filed charges you do not have a criminal conviction for DUI BUT if you failed to request a DMV hearing within 10 days of your arrest OR had a hearing and lost then you have a DUI in the eyes of the DMV. You have to jump through certain hoops like file an SR-22 and pay a reinstatement fee once the suspension has been served. If charges were filed in court within one year of your arrest you also have a DUI case, and may have a warrant if you failed to appear at your arraignment. A DUI lawyer in your area may be able to help you determine what has happened and what, if anything, can be done.
