Well, anytime a lawyer takes a case, we don't know what the outcome is going to be when we take the case. You're essentially paying us for the time that we spend on your case and the experience that we have to try to figure out whether or not you have a defense in your case.
The answer to that question is, yes, hiring a lawyer can make a difference. You may not get out of the DUI but we may be able to mitigate the penalties in some ways for you. We may be able to eliminate the ignition interlock, we may be able to reduce community service hours to some extent, we may be able to keep you out of jail if you're facing mandatory jail. You should always contact an attorney, have your case reviewed in order to determine the best course of action to take.
