You were arrested leaving a Joliet bar with a .10% BAC – barely over the legal limit – but prosecutors charged you with Class 4 felony aggravated DUI carrying one to three years in prison instead of the Class A misdemeanor you expected. Why? Because you were driving on a license suspended three years ago for unpaid parking tickets, and Illinois law under 625 ILCS 5/11-501(d)(1)(G) treats any DUI committed while your license is suspended or revoked for any prior DUI-related reason as automatic felony aggravated DUI regardless of your current BAC level or driving behavior. Understanding what elevates DUI charges from misdemeanors to felonies is critical because the distinction means the difference between up to 364 days in county jail versus mandatory prison sentences, between keeping your criminal record eligible for future expungement versus permanent felony convictions that destroy employment opportunities, and between probation eligibility versus non-probationable sentences requiring you to serve every day of your prison term.
