Blog ImageDriving Under the Influence (DUI) charges in Illinois remain one of the most common criminal offenses, with severe impacts on your freedom, finances, and driving privileges. As a Joliet criminal defense attorney with over 20 years of experience, including my time as a former Will County prosecutor, I’ve defended countless clients against DUI allegations, often achieving reductions, dismissals, or favorable plea deals. At the Law Office of Jack L. Zaremba, we focus on aggressive representation for DUI cases in Will County, where enforcement is rigorous on highways like I-80 and local roads. In this blog post, we’ll cover DUI definitions under Illinois law, penalties, common defenses, and how to protect your license in 2025.
