Chicago DUI Penalties
Illinois DUI penalties under 625 ILCS 5/11-501 are structured by offense count, BAC level, and aggravating factors. The same statute can produce a manageable first-offense misdemeanor or a Class X felony with decades of prison exposure, depending on which factors apply. Understanding where your case falls in the penalty structure is the first step toward planning the defense. Call (888) 828-2305 for a free 24/7 consultation with a Chicago DUI lawyer.

Collateral Consequences Beyond the Penalty Statute
The statutory penalties are only part of the cost of a DUI conviction. Collateral consequences typically include:
- Insurance. SR-22 high-risk insurance certification is required for license reinstatement. Premiums multiply, often 3x to 5x prior rates, for 3 to 5 years.
- Employment. CDL holders lose commercial driving privileges. Professional licensing boards (nursing, medical, legal, real estate, financial) require disclosure and may impose discipline.
- Immigration. Non-citizen drivers face removal proceedings for certain DUI convictions, particularly aggravated DUI.
- Permanent record. DUI convictions in Illinois cannot be expunged or sealed. They remain visible on criminal background checks for life.
- BAIID costs. Installation, monthly monitoring, and removal of the ignition interlock device adds $1,000 to $1,500 over the required period.
