After a DUI arrest, you have only 10 days in which to request a DMV hearing to stop the suspension of your driver's license. This is completely separate from the criminal case, which is handled in court. If you do not act at once to schedule a DMV hearing, you lose your opportunity, and your license will be automatically suspended. Even if you are found "not guilty" in criminal court, the DMV operates separately and may or may not allow you to get your driver's license reinstated.
The most urgent issue after an arrest for DUI is to schedule the DMV hearing; of course, an experienced DUI defense firm such as Jones Law can request the hearing for you and defend you at both the DMV and court hearings.
