If you are searching for Illinois DUI penalties right now, you are probably looking at a court date, a suspended license, or both. That is a hard place to be at 11 pm with a phone in your hand and a hundred questions running through your head.
Illinois DUI convictions carry real consequences: jail time, fines, a license revocation, and in some cases, a felony record. The same driving under the influence statute applies whether the impairment came from alcohol or drugged driving, and the exact penalty depends on how many prior DUIs you have, your blood alcohol concentration, and whether anyone was hurt. A charge is not a conviction, and the penalties below are not automatic. Contact Dohman Law Group today for a free case review and find out what your specific charge means for you.
Below, we break down the current Illinois DUI penalty chart by offense, plus the license consequences that hit separately from your criminal case.
Illinois DUI Penalties at a Glance
Illinois DUI convictions are prosecuted under 625 ILCS 5/11-501. Here is how penalties escalate by offense and circumstance.
| Offense or circumstance | Charge classification | Possible jail or prison | Possible fine | License revocation |
|---|---|---|---|---|
| First DUI | Class A misdemeanor | Up to 364 days | Up to $2,500 | Minimum 1 year (2 years if under 21) |
| First DUI, BAC 0.16% or higher | Class A misdemeanor | Up to 364 days | Minimum $500, up to $2,500 | Minimum 1 year |
| Second DUI | Class A misdemeanor | Mandatory minimum 5 days or 240 hours community service | Up to $2,500 | Minimum 5 years |
| Third DUI | Class 2 felony | 3 to 7 years | Up to $25,000 | Minimum 10 years |
| Fourth DUI | Class 2 felony, no probation | 3 to 7 years | Up to $25,000 | Lifetime, no relief |
| Fifth DUI | Class 1 felony, no probation | 4 to 15 years | Up to $25,000 | Lifetime, no relief |
| Sixth or later DUI | Class X felony, no probation | 6 to 30 years | Up to $25,000 | Lifetime, no relief |
| DUI causing great bodily harm | Class 4 felony | 1 to 12 years | Up to $25,000 | Varies by prior record |
| DUI causing one death | Class 2 felony | 3 to 14 years | Up to $25,000 | Varies by prior record |
| DUI causing two or more deaths | Class 2 felony | 6 to 28 years | Up to $25,000 | Varies by prior record |
These are the ranges set by Illinois law. What actually happens in your case depends on the evidence and the specific facts, so treat this chart as a starting point rather than a prediction.
What a First-Time DUI Actually Means
A first DUI in Illinois is a Class A misdemeanor: up to 364 days in jail and a fine of up to $2,500, though many first-time offenders never see jail time. What almost everyone sees is a license consequence.
Two circumstances add mandatory extra penalties on top of the standard first-offense range:
- BAC of 0.16% or higher: mandatory minimum fine of $500, plus 100 hours of community service.
- Passenger under 16 in the vehicle: up to 6 months in jail, mandatory minimum fine of $1,000, plus 25 days of community service in a program that benefits children.
Some first-time offenders qualify for court supervision, which avoids a conviction on your record if you complete the terms the court sets, typically an alcohol/drug evaluation, an alcohol education program, or mandatory DUI classes, and community service. It is generally available only if your BAC was under 0.16% and no one was hurt. Ask your lawyer whether you qualify, since it is one of the few ways to keep a first-time DUI off your criminal record entirely.
Second, Third, and Felony DUI Penalties
A second DUI is still a Class A misdemeanor, but the court has less flexibility: a mandatory minimum of 5 days in jail or 240 hours of community service, no exceptions, and license revocation jumps to a minimum of 5 years.
A third DUI is where Illinois law shifts from misdemeanor to felony:
- Third DUI: Class 2 felony, 3 to 7 years in prison, minimum 10-year revocation.
- Fourth DUI: Class 2 felony, no probation available.
- Fifth DUI: Class 1 felony, no probation available.
- Sixth or later DUI: Class X felony, no probation available, with prison terms running into decades.
Illinois does not use a look-back period for DUI enhancement. A conviction from 20 years ago still counts toward whether your current charge is a second, third, or fourth offense.
Certain circumstances turn even a first or second DUI into an aggravated, felony-level charge regardless of offense number. Aggravating factors that can move your case from a misdemeanor courtroom to a felony one include:
- Driving on a license already revoked or suspended for a prior DUI
- Driving without a valid license or insurance
- Driving a school bus with passengers on board
- Causing a crash that results in great bodily harm, permanent disability, or death
Depending on which factor applies and how many prior offenses you have, Illinois felony DUI sentencing laws can classify a single charge anywhere from Class 4 to Class X felonies.
License Consequences: Separate From Your Criminal Case
Your license can be suspended before you are ever convicted of anything. Illinois uses a Statutory Summary Suspension, an automatic administrative suspension tied to your test result rather than your court outcome, and it takes effect on the 46th day after arrest.
The length depends on what happened at the stop:
- Failed a chemical test (BAC 0.08% or higher): 6-month suspension on a first offense.
- Refused testing: 12-month suspension on a first offense.
Illinois is an implied consent state: driving here means you have already agreed to chemical testing if an officer has probable cause. Refusing does not stop the case against you; it just adds a longer suspension.
If you qualify, a Monitoring Device Driving Permit lets you keep driving during your suspension as long as you install a Breath Alcohol Ignition Interlock Device, or BAIID, in your vehicle. First-time offenders who complied with testing and have no prior DUI conviction or supervision in the past 5 years are generally eligible; drivers who refused testing typically are not.
After a conviction, a separate license revocation follows, and reinstatement is not automatic. It requires a formal hearing before the Illinois Secretary of State. Once you clear the minimum revocation period, you may also be able to apply for a Restricted Driving Permit, which is different from an MDDP and covers limited driving after your license has actually been revoked, such as travel to work, school, or medical appointments. Our license reinstatement page walks through what that process looks like.
CDL Holders and Drivers Under 21 Face Tougher Rules
Commercial driver’s license holders
If you hold a commercial driver’s license, the legal BAC limit while operating a commercial vehicle drops to 0.04%, half the standard limit.
- A first DUI conviction, even one in your personal vehicle, means a 1-year CDL disqualification.
- Hauling hazardous materials at the time extends that to 3 years.
- A second offense means a lifetime CDL disqualification.
- CDL holders are not eligible for a Monitoring Device Driving Permit for commercial driving privileges during a disqualification.
A DUI conviction can also trigger a professional licensing review for school bus drivers, nurses, teachers, and other regulated professions, separate from anything the Secretary of State does to your driving privileges.
Drivers under 21
Illinois applies a zero-tolerance law to drivers under 21:
- Any detectable blood alcohol level below 0.08%: a 3-month suspension on a first offense.
- BAC of 0.08% or higher: full adult DUI penalties apply, plus an extended 2-year license revocation instead of the standard 1 year.
What to Do After a DUI Arrest
The hours right after an arrest matter:
- Be polite and cooperative with officers, but avoid volunteering details about where you were or what you had to drink.
- Write down what you remember about the stop while it is fresh: the time, the location, any field sobriety test you were asked to perform, the officer’s stated observations, and what was said.
- Watch your mail. The suspension notice and your court date both come with fast-moving deadlines, including a narrow window to request a hearing on your license suspension.
- Speak with legal counsel before your first court date. Penalties can vary based on your BAC, your prior record, and the facts of the stop, and an attorney can review the evidence and explain your realistic options.
