DUI Defense in Illinois — what to do right now
The law in Illinois: DUI Defense
Illinois DUI is governed by 625 ILCS 5/11-501, which makes it illegal to drive with a blood-alcohol concentration of 0.08 or more, while under the influence of alcohol, drugs or intoxicating compounds, or with any amount of a controlled substance in your system. A first or second offense is a Class A misdemeanor; the same statute defines every 'aggravated DUI' felony tier above that. The criminal charge is heard in the Circuit Court of the county where you were stopped — for example, the Circuit Court of Cook County in Chicago, or the circuit serving Aurora, Joliet, Rockford, Peoria or Springfield.
Running alongside the criminal case is a completely separate proceeding under the implied-consent law, 625 ILCS 5/11-501.1. By driving on Illinois roads you have already consented to chemical testing on a lawful DUI arrest. If you failed the test (0.08 or above, or drugs) or refused it, the Secretary of State imposes a 'statutory summary suspension' that takes effect automatically on the 46th day after notice — no hearing, no conviction required. Illinois has no separate DMV; the Secretary of State is the licensing agency, and it also runs the BAIID (ignition interlock) program and the reinstatement hearings.
Your one tool against that suspension is a Petition to Rescind under 625 ILCS 5/2-118.1, filed in the same Circuit Court that hears your criminal case but legally distinct from it — civil in nature. You must file within 90 days of the notice, and the court must hold the hearing within 30 days of your request (or your first court date, whichever is later). Because the two cases are separate, you can win the rescission and still face the DUI, or beat the DUI and still lose the suspension. Critically, the only lawful way to drive during a first summary suspension is a Monitoring Device Driving Permit (MDDP) with a court-authorized ignition interlock under 625 ILCS 5/6-206.1; Illinois does not hand out a plain 'hardship license.' Driving on a suspended license instead is its own charge under 625 ILCS 5/6-303.
Sentencing add-ons attach almost automatically on a DUI conviction — a mandatory alcohol/drug evaluation, recommended treatment, and a victim impact panel. Drivers under 21 face a wholly separate Zero Tolerance suspension under 625 ILCS 5/11-501.8 for any detectable alcohol. Appeals of a conviction or a suppression ruling run to the Illinois Appellate Court and, rarely, the Illinois Supreme Court. And a non-citizen convicted of an aggravated DUI can face removal proceedings in federal immigration court (EOIR) under 8 U.S.C. § 1227(a)(2) — a federal consequence, separate from the state case.

Courts & Agencies

- Federal immigration court (EOIR), under U.S. Department of Justice — only if an aggravated DUI conviction triggers removal for a non-citizen
Penalties & Deadlines
- Day 46 — your license is suspended automatically, before any trial
- 90 days from notice — deadline to file the Petition to Rescind Statutory Summary Suspension; hearing within 30 days of your request
- MDDP — ignition interlock must be installed within 14 days of permit issuance or the Secretary of State cancels the permit
- First DUI — up to 364 days jail (no minimum), fines to $2,500, 1-year revocation on conviction
- Reinstatement fee — $250 (first suspension) / $500 (each later one), on top of MDDP and program costs
The 46-day blindside: your license goes before your trial does
Almost everyone arrested for DUI in Illinois braces for the criminal court date and never sees the real ambush coming. Under the statutory summary suspension, the Secretary of State takes your license automatically on the 46th day after notice — no conviction, no judge, no hearing — and your only counter is a Petition to Rescind you must file within 90 days in the Circuit Court of the arresting county. Miss that window and the suspension simply stands. And because Illinois offers no plain hardship license, the only way to keep driving on a first suspension is an MDDP with an ignition interlock, installed within 14 days of the permit.

Likely outcomes & penalties
Illinois DUI penalties escalate sharply by offense number and by aggravating facts. These are realistic current ranges under the Illinois Vehicle Code — your own exposure depends on your record, your BAC, and whether anyone was hurt.
First offense (Class A misdemeanor)
Up to 364 days jail (no mandatory minimum), fines up to $2,500, and a 1-year license revocation on conviction. Court supervision is often available — and because supervision is not a conviction, it avoids the mandatory revocation. But Illinois allows DUI supervision only once in a lifetime.
Second offense (Class A misdemeanor)
Mandatory minimum of 5 days jail OR 240 hours community service, up to 364 days jail, and a minimum 5-year revocation if it falls within 20 years of the first. Court supervision is not available the second time around.
Third offense — Aggravated DUI (Class 2 felony)
3 to 7 years in prison (probation possible), fines up to $25,000, and a 10-year minimum revocation. A fourth offense brings lifetime revocation — among the strictest repeat regimes in the country.
Aggravated DUI by facts (felony regardless of count)
DUI causing great bodily harm, permanent disability or disfigurement is a Class 4 felony; DUI causing a death is a Class 2 felony carrying 3 to 14 years (6 to 28 years for more than one death), with prison normally mandatory. A passenger under 16, a school-zone injury, or driving on a DUI-revoked license can also elevate the charge to a felony.
Mistakes to avoid
⚠️
Treating the arrest as one case. The criminal DUI and the statutory summary suspension are two separate tracks — fighting one does nothing for the other, and the suspension moves faster.
⚠️
Letting the 46th day pass without filing. The suspension is automatic; if you wait for your criminal court date to raise it, you may already be past the 90-day window to file a Petition to Rescind under 625 ILCS 5/2-118.1.
⚠️
Assuming you can get a 'hardship license' like in other states. Illinois has none for a summary suspension — the only lawful way to drive is an MDDP with an ignition interlock, and the device must be installed within 14 days or the Secretary of State cancels the permit.
⚠️
Thinking refusing the breath test protects you. In Illinois refusal is punished harder than failing on the license side — a 12-month summary suspension versus 6 for a first offender, and 3 years versus 1 for a repeat — the opposite of what most drivers assume.
⚠️
Burning your one lifetime court supervision carelessly, or pleading a first DUI straight to a conviction when supervision could have kept it off your record and avoided the mandatory revocation.

FAQ — DUI Defense in Illinois
I was just arrested for DUI in Illinois — can I still drive?
Usually yes, but only until the 46th day after the notice you were given. On day 46 the statutory summary suspension takes effect automatically, with no further warning. That short window is exactly when you need to act on a Petition to Rescind. Call 1-844-690-0555 free, any hour, and we'll help you figure out which day you're on.
What is the statutory summary suspension, and how is it different from the criminal case?
It's a separate, automatic license suspension imposed by the Secretary of State under 625 ILCS 5/11-501.1 after you fail or refuse a chemical test — no conviction needed. Your criminal DUI is a different, slower proceeding in Circuit Court. You can beat one and lose the other. Most people don't realize there are two tracks. Call 1-844-690-0555 and we'll explain both for free.
How do I fight the suspension — what's a Petition to Rescind?
It's a petition you file under 625 ILCS 5/2-118.1 in the Circuit Court of the county where you were arrested, within 90 days of the notice, asking the judge to lift the summary suspension. The court must hold the hearing within 30 days of your request. Miss the 90-day window and the suspension stands unchallenged. Call 1-844-690-0555 free to learn how the petition works for your case.
Can I get a hardship license to drive to work during my suspension?
Not the way other states do it. For a first summary suspension, Illinois offers only a Monitoring Device Driving Permit (MDDP) with a court-authorized ignition interlock — there is no plain 'hardship license.' The interlock must be installed within 14 days of permit issuance or the Secretary of State cancels it. Call 1-844-690-0555 and our assistant will walk you through MDDP eligibility for free.
I refused the breathalyzer — is that better or worse?
On the license side it's generally worse. Refusal triggers a longer summary suspension than failing — 12 months versus 6 for a first offender, and 3 years versus 1 for a repeat — which surprises most people. It can still matter for the criminal case, though. Call 1-844-690-0555 free to talk through what your refusal means.
What happens to a first DUI in Illinois — will I go to jail?
A first DUI is a Class A misdemeanor with up to 364 days possible but no mandatory minimum jail, plus fines up to $2,500 and a 1-year revocation on conviction. Many first offenders qualify for court supervision, which avoids a conviction — but you get it only once in a lifetime. Call 1-844-690-0555 to understand your options for free.
What is court supervision and why does everyone say it matters?
Supervision is a disposition that, if you complete it, ends in dismissal rather than a DUI conviction — which means no mandatory license revocation. Illinois law allows it for DUI only once in your lifetime, so using it wisely is critical. It's one of the most valuable tools in an Illinois first-DUI case. Call 1-844-690-0555 free to learn whether you're eligible.
My teenager got a DUI or a Zero Tolerance citation — what now?
Drivers under 21 face a separate Secretary of State suspension under the Zero Tolerance law (625 ILCS 5/11-501.8) for any detectable alcohol — 3 months for a first failed test, 6 months for a first refusal — on top of any criminal DUI. The right to request a hearing runs from the notice. Call 1-844-690-0555 free, day or night, and we'll explain both tracks.
This is my third DUI — how bad is it?
A third DUI is aggravated DUI, a Class 2 felony carrying 3 to 7 years in prison (though probation is possible), fines up to $25,000, and a minimum 10-year revocation. A fourth means lifetime revocation. This is serious felony territory where a lawyer is essential. Call 1-844-690-0555 free to understand exactly what you're facing.
Are you a law firm or a public defender?
No. Legal Hotline is not a law firm and not a public defender. We give free legal information, not legal advice, and the call creates no attorney-client relationship. If you want representation, we can help you book a paid consultation with an Illinois-licensed DUI attorney. Start with the free call: 1-844-690-0555, any hour.
