The answer truly is it depends. The facts from your underlying DUI will come into play, along with the facts of this offense. It is a class one misdemeanor and you can be sentenced to up to 12mos in jail and up to a $2500 fine. If you had a good behavior period on your underlying DUI, this could trigger a violation of your good behavior and that is another class one misdemeanor. I would speak to an attorney immediately about what defenses you might have. Many attorneys offer free consultations and wishing you good luck!
