There are no guarantees or absolutes in law. Just because you have been charged with a DUI does not mean you will be convicted. Right from the start it is possible that a DUI attorney can deal with the substantive issues of your situation before charges are ever filed. In fact, a DUI attorney may also be able to stop charges from ever being filed. Finding the right attorney and hiring them early in the process is always best. Even in a situation in which a conviction will occur, an experienced criminal defense attorney can help reduce the penalties and guide you through the system so no critical mistakes are made. There are many points along the process which if not done right can create more problems.
