What Happens If You Get a DUI in Illinois? License, Costs, Record

If you get a DUI in Illinois, two separate processes start running at once: an administrative suspension of your driver’s license handled by the Secretary of State, and a criminal case handled by the court. A standard first offense is a Class A misdemeanor punishable by up to 364 days in jail and a $2,500 fine,1Illinois General Assembly. Illinois Code 730 ILCS 5/5-4.5-55 – Class A Misdemeanor Sentence but the fallout extends well past the courtroom: your license goes down automatically before any judge rules on anything, you’ll pay for an alcohol evaluation and whatever treatment it recommends, your insurance will jump for years, and prior offenses or aggravating circumstances can turn the case into a felony with mandatory prison time. The 0.08 blood-alcohol threshold applies to alcohol, and Illinois enforces a parallel limit for THC and other drugs.2Illinois General Assembly. Illinois Code 625 ILCS 5/11-501 – Driving While Under the Influence

Your License Goes Down First

Before anything happens in criminal court, the statutory summary suspension kicks in. The arresting officer gives you written notice at the scene, and the suspension takes effect on the 46th day after that notice. It’s a civil action by the Secretary of State, triggered the moment you either fail or refuse chemical testing.

How long you lose your license depends on your record and whether you took the test:

“Repeat offender” here means anyone with a prior DUI arrest, conviction, or summary suspension. Refusing the test always doubles the penalty compared to failing it. That matters at the roadside when the officer reads the implied-consent warning.4Illinois General Assembly. Illinois Code 625 ILCS 5/11-501.1 – Suspension of Drivers License

You can fight the suspension by filing a Petition to Rescind in the circuit court handling your DUI case. Common arguments are that the officer lacked reasonable cause for the stop or that the testing equipment malfunctioned. The clock does not stop while you file, so the petition needs to move fast.

The Criminal Case for a First Offense

The criminal case runs on its own track. A standard first-offense DUI is a Class A misdemeanor: up to 364 days in county jail and up to $2,500 in fines.1Illinois General Assembly. Illinois Code 730 ILCS 5/5-4.5-55 – Class A Misdemeanor Sentence Most first offenders do not see anywhere near the top of that range, but the conviction itself leaves a permanent mark on your driving and criminal records.

If your BAC was 0.16 or higher, the statute requires a minimum $500 fine and at least 100 hours of community service on top of the rest of the sentence.2Illinois General Assembly. Illinois Code 625 ILCS 5/11-501 – Driving While Under the Influence That community service alone eats weeks of weekends.

Court Supervision: Keeping It Off Your Record

For most first-time defendants, the real goal is court supervision rather than a conviction. Supervision is an Illinois-specific disposition where the judge withholds a conviction and sets conditions you must complete over a period of up to two years. The conditions usually include fines, an alcohol and drug evaluation, a victim impact panel, and whatever treatment the evaluation recommends.

Finish everything, and the DUI does not appear as a conviction on your record. That difference matters for employment background checks and professional licensing. The catch: supervision for a DUI is a once-in-a-lifetime option. If you’ve ever received supervision for a DUI before, or been convicted of one, a judge cannot grant it.5Illinois General Assembly. Illinois Code 730 ILCS 5/5-6-1 – Supervision Fail to complete any term, and the court can revoke supervision and enter a full conviction.

When a DUI Becomes a Felony

You do not need prior offenses to end up facing felony charges. A single DUI is charged as an aggravated DUI if any of these apply:

  • The crash caused great bodily harm or death to another person.
  • A passenger under 16 was in the vehicle.
  • You were driving on a license already revoked or suspended for a prior DUI.
  • You had no valid driver’s license or permit at all.
  • The vehicle was uninsured.
  • You were driving a school bus with passengers.2Illinois General Assembly. Illinois Code 625 ILCS 5/11-501 – Driving While Under the Influence

The felony class depends on which factor applies. A DUI crash that kills someone is treated far more severely than driving uninsured while impaired.

Prior offenses escalate the penalty on their own. A second DUI stays a Class A misdemeanor but carries a mandatory minimum of five days in jail or 240 hours of community service. A third DUI is a Class 2 felony with a three-to-seven-year prison range.6Illinois General Assembly. Illinois Code 730 ILCS 5/5-4.5-35 – Class 2 Felony Sentence A fourth makes probation unavailable. By the sixth, it’s a Class X felony with a six-to-30-year range.7Illinois General Assembly. Illinois Code 730 ILCS 5/5-4.5-25 – Class X Felony Sentence At the fourth offense and above, mandatory add-on fines kick in when the BAC was 0.16 or more ($5,000 minimum) or when a child under 16 was in the car ($25,000 plus 25 days of community service benefiting children).2Illinois General Assembly. Illinois Code 625 ILCS 5/11-501 – Driving While Under the Influence

Repeat and aggravated offenders also face vehicle forfeiture. The state can seize and permanently take the vehicle used in a DUI if the driver’s license was revoked or suspended for a prior DUI, if it’s a third-or-later DUI, if the driver had no license, or if the vehicle was uninsured.8Illinois General Assembly. Illinois Code 720 ILCS 5/36-1 – Seizure and Forfeiture

Getting Your License Back

The summary suspension is temporary. A DUI conviction triggers a separate, longer revocation through the Secretary of State. Minimum waiting periods before you can even apply for reinstatement climb fast:

The lifetime revocation is literal. The statute says the person “may not make application for a license” at all, with a narrow exception for out-of-state residents after ten years.9Illinois General Assembly. Illinois Code 625 ILCS 5/6-208 – Mandatory Revocation

Reinstatement requires a formal hearing before the Secretary of State, a $500 reinstatement fee, proof you completed treatment, and documented sobriety.10Illinois Secretary of State. Driver’s License Reinstatement Fees Expect to drive on a restricted permit with an ignition interlock before full privileges come back.

During the summary suspension period, first-time offenders can apply for a Monitoring Device Driving Permit (MDDP), which requires a Breath Alcohol Ignition Interlock Device (BAIID) in every vehicle you operate.11Illinois General Assembly. Illinois Code 625 ILCS 5/6-206.1 – Monitoring Device Driving Permit The device needs a clean breath sample before the engine starts and periodically while driving. The MDDP lets you drive anywhere at any time except in a commercial motor vehicle, costs $30 per month on top of the device rental, and the BAIID has to be installed within 14 days or the permit is cancelled.12Legal Information Institute. Illinois Administrative Code 92 Section 1001.444 – MDDP Provisions

The Evaluation and Treatment You’ll Have to Complete

Nearly every DUI disposition in Illinois requires a professional alcohol and drug evaluation. A licensed evaluator reviews your driving history, chemical test results, and personal history, then assigns a risk classification that determines how much treatment you need:

  • Minimal Risk: 10 hours of DUI Risk Education.
  • Moderate Risk: 12 hours of DUI Risk Education.
  • Significant Risk: 10 hours of education plus at least 20 hours of substance abuse treatment.
  • High Risk: at least 75 hours of treatment, followed by an ongoing continuing care plan.13Illinois Department of Human Services. DUI Processes and Evaluations

You pay for all of it. Completion is typically a condition of court supervision, probation, and license reinstatement, so skipping or stalling stops the whole case from moving.

What It Actually Costs

The court fine is usually the smallest line item. After a DUI conviction, Illinois requires you to file an SR-22 certificate of financial responsibility with the Secretary of State and keep it for three years.14Illinois Secretary of State. Financial Responsibility SR-22 Insurance The SR-22 is just a form, but it flags you as a high-risk driver, and premiums climb significantly for that entire window.

Attorney fees for a first-offense DUI typically run $2,500 to $10,000, depending on complexity and whether the case goes to trial. Add towing and storage from the night of arrest, the $500 reinstatement fee, BAIID rental and monitoring, and the evaluation and treatment programs. A first-offense DUI commonly costs $10,000 or more over the following few years, even without jail time.

What a DUI Does to Your Job, License, and Travel

Commercial driver’s license holders take the hardest hit. Under federal regulations, a first DUI conviction disqualifies you from operating any commercial motor vehicle for one year, regardless of whether you were driving your personal car or a commercial vehicle at the time. If you were hauling hazardous materials, it’s three years. A second DUI-related disqualification is a lifetime ban from commercial driving.15eCFR. 49 CFR 383.51 – Disqualification of Drivers

Licensed professionals in healthcare, law, education, and finance are generally required to self-report criminal convictions to their licensing boards. A misdemeanor DUI may trigger a board investigation and conditions like monitoring or treatment; a felony DUI can lead to suspension or revocation of the professional license.

If the DUI is charged as an aggravated felony, federal law prohibits you from possessing any firearm or ammunition, because the ban applies to anyone convicted of a crime punishable by more than a year of imprisonment.16Office of the Law Revision Counsel. 18 USC 922 – Unlawful Acts

A single DUI conviction can also make you inadmissible to Canada, which treats impaired driving as a serious criminal offense. Even a sealed or expunged U.S. record can trigger a denial at the border. A Temporary Resident Permit allows short-term entry for a compelling reason; a permanent fix requires applying for Criminal Rehabilitation, available once five years have passed since you completed all terms of your sentence.

For non-citizens, a DUI can create immigration problems. A single misdemeanor DUI is not typically a crime of moral turpitude, but a second DUI, or a DUI committed while driving on a suspended or revoked license, may qualify. A felony DUI almost certainly counts as an aggravated felony for immigration purposes, which can trigger removal proceedings or block a green card or naturalization. Non-citizens facing any DUI charge in Illinois should talk to an immigration attorney before entering a plea, because the best criminal defense strategy and the best immigration strategy do not always line up.
