A first-offense DUI in Illinois carries a mandatory minimum one-year driver’s license revocation, fines up to $2,500, and a required SR-22 filing for a minimum of three years under 625 ILCS 5/6-205. Illinois law defines DUI under 625 ILCS 5/11-501 as operating a vehicle with a blood alcohol concentration (BAC) of 0.08% or higher, though drivers can be charged at lower BAC levels if impairment is evident. The SR-22 requirement means your auto insurance premiums will increase significantly, since driving record — and a DUI specifically — is among the largest factors insurers weigh when setting price, according to the Insurance Information Institute (III, 2024). These consequences apply statewide, though Cook County courts and Chicago municipal enforcement may layer additional case processing on top of state minimums.

What Are the Legal Penalties for a DUI in Illinois?
Illinois DUI penalties are governed by 625 ILCS 5/11-501 and escalate sharply with each subsequent offense. A first-offense DUI is classified as a Class A misdemeanor, carrying up to 364 days in jail, fines up to $2,500, and a mandatory one-year driver’s license revocation. Drivers under 21 face a two-year revocation on a first offense under the same statute.
A second DUI offense remains a Class A misdemeanor with a mandatory minimum of five days in jail or 240 hours of community service, plus a five-year license revocation if the second offense occurs within 20 years of the first. A third DUI is a Class 2 felony — punishable by 3 to 7 years in prison — and results in a 10-year license revocation.
Illinois also imposes an Aggravated DUI classification (Class 4 felony minimum) when the offense involves a BAC of 0.16% or higher, a passenger under age 16 in the vehicle, driving in a school zone, causing bodily harm to another person, or driving without valid insurance or a valid license at the time of arrest.
| Offense | Classification | Max Jail | License Revocation | Min Fine |
|---|---|---|---|---|
| 1st offense | Class A Misdemeanor | 364 days | 1 year (2 yrs under 21) | Up to $2,500 |
| 2nd offense | Class A Misdemeanor | 364 days | 5 years (within 20 yrs) | Up to $2,500 |
| 3rd offense | Class 2 Felony | 3–7 years | 10 years | Up to $25,000 |
| Aggravated DUI | Class 4 Felony (min) | 1–3 years | Varies | Up to $25,000 |

What Is a Statutory Summary Suspension in Illinois?
A statutory summary suspension is an automatic, administrative suspension of your driving privileges that begins 46 days after your DUI arrest — regardless of whether you’ve been convicted in court. Under 625 ILCS 5/11-501.1, drivers who fail a chemical test (BAC ≥ 0.08%) face a six-month suspension on a first offense. Drivers who refuse chemical testing face a 12-month suspension on a first offense. This suspension is separate from any court-ordered penalty and is handled entirely by the Illinois Secretary of State’s office.
First-time DUI offenders may be eligible for a Monitoring Device Driving Permit (MDDP), which allows driving during the suspension period provided a Breath Alcohol Ignition Interlock Device (BAIID) is installed in the vehicle. The MDDP is not available to drivers with prior DUI-related suspensions or revocations.
What Is a License Revocation and How Is It Different From a Suspension?
A license revocation is a court-imposed cancellation of your driving privileges following a DUI conviction, requiring a formal reinstatement hearing before the Illinois Secretary of State — a suspension simply ends automatically after its term. Revocations for a first DUI last a minimum of one year under 625 ILCS 5/6-205. After the revocation period ends, drivers must petition the Secretary of State for reinstatement, complete an alcohol/drug evaluation, provide proof of SR-22 insurance, and pay reinstatement fees.
According to the Illinois Secretary of State’s fee schedule, reinstating a license after a DUI-related revocation costs $500, while reinstating after a first-offense statutory summary suspension costs $250 (these are two separate processes that can both apply to the same DUI incident). Drivers with multiple DUIs may face a formal hearing before a Secretary of State hearing officer, while first-time offenders may qualify for an administrative review.
What Is a BAIID and When Is It Required in Illinois?
A Breath Alcohol Ignition Interlock Device (BAIID) is a breathalyzer installed in a vehicle that prevents the engine from starting if the driver’s BAC exceeds a preset limit — in Illinois, that limit is 0.025%. BAIID installation is mandatory for any driver seeking an MDDP during a statutory summary suspension, and is also required for drivers seeking a Restricted Driving Permit (RDP) during a revocation period.
According to the Illinois Secretary of State’s BAIID fee schedules, vendor installation costs range from $70 to $480 with monitoring or calibration fees of $15 to $70 per visit, depending on the certified vendor selected. In addition, the Secretary of State charges a separate fixed $30 monthly MDDP monitoring fee plus an $8 permit fee, paid directly to the state regardless of which vendor installs the device. Drivers bear all costs associated with BAIID installation and monitoring unless declared indigent.
How Does a DUI Affect Your Auto Insurance in Illinois?
A DUI conviction in Illinois will increase your auto insurance premiums substantially and trigger an SR-22 filing requirement that stays on your record for a minimum of three years. According to the Insurance Information Institute (III, 2024), driving record is one of the most heavily weighted factors insurers use to set premium, and a DUI specifically produces among the largest increases of any single violation — though the exact percentage varies significantly by insurer, county, and individual driving history, so no single published figure applies universally to every Illinois driver.
What Is an SR-22 and Why Do Illinois DUI Drivers Need One?
An SR-22 is a Certificate of Financial Responsibility — a document filed by your insurance company directly with the Illinois Secretary of State certifying that you carry at least the state’s minimum required liability coverage. The SR-22 is not a type of insurance policy; it is a filing attached to an existing or new auto insurance policy. Under 625 ILCS 5/7-601, Illinois requires SR-22 filings for a minimum of three years following a DUI conviction, and any lapse in coverage — even one day — can restart that three-year clock.
Illinois minimum liability coverage requirements are $25,000 per person for bodily injury, $50,000 per accident for bodily injury, and $20,000 per accident for property damage. You can review the full breakdown of Illinois minimum car insurance requirements to understand exactly what your policy must include before an SR-22 can be filed.
How Long Does a DUI Stay on Your Insurance Record in Illinois?
A DUI conviction remains on your Illinois driving record permanently, but most insurance companies look back three to five years when calculating premiums, according to the Insurance Information Institute (III, 2024). Illinois does not allow DUI convictions to be expunged from your driving record under current law — unlike some other traffic violations. The practical insurance impact is most severe in years one through five following conviction, with premiums gradually stabilizing after the SR-22 requirement ends at the three-year mark, assuming no additional violations occur. Understanding the distinction in terminology also matters here — see DWI vs. DUI in Illinois for how Illinois law treats these terms.
What Are the Steps to Reinstate Your License After an Illinois DUI?
Reinstating an Illinois driver’s license after a DUI revocation requires completing a specific sequence of steps — skipping any one of them will result in denial. The Illinois Secretary of State’s office administers all reinstatement proceedings, and the process differs slightly depending on whether you qualify for an informal hearing (typically first-time offenders) or a formal hearing (repeat offenders or those with aggravated DUI convictions). For a deeper walkthrough specific to a first offense, see first-time DUI offense license reinstatement in Illinois.
- Complete your revocation period. The minimum one-year revocation must expire before you can apply for reinstatement.
- Obtain a drug and alcohol evaluation. A licensed evaluator must assess your risk classification (minimal, moderate, significant, or dependent).
- Complete any recommended treatment. Drivers classified above “minimal risk” must complete a corresponding treatment or education program before reinstatement will be granted.
- File proof of SR-22 insurance. Your insurance company must file the SR-22 directly with the Secretary of State — you cannot file it yourself.
- Pay the $500 reinstatement fee. Payment is made to the Illinois Secretary of State’s office.
- Attend your Secretary of State hearing. First-time offenders may qualify for an administrative (informal) review; repeat offenders require a formal hearing with a hearing officer.
- Receive your reinstatement order. If approved, you’ll receive a Restricted Driving Permit or full reinstatement depending on your eligibility.
How Do Chicago and Cook County Handle DUI Cases?
Chicago and Cook County DUI cases are prosecuted under the same Illinois state statutes but carry additional local enforcement layers that can affect outcomes. Cook County operates a dedicated DUI court system under the Circuit Court of Cook County, and the county also has a Drug Court / DUI Diversion program available to qualifying first-time offenders, which can result in reduced charges upon successful completion. Eligibility is determined by the Cook County State’s Attorney’s office and is not available to drivers with prior DUI convictions or cases involving injury.
Does Chicago Have Additional DUI Penalties Beyond State Law?
No. Chicago does not impose separate municipal DUI penalties beyond Illinois state law — the same statutes apply citywide and statewide. However, the city’s enforcement environment is notably active, with Chicago Police Department DUI enforcement units operating year-round saturation patrols. Cook County has historically ranked among the state’s highest-volume DUI arrest jurisdictions, reflecting both population density and consistent enforcement activity rather than any unique municipal penalty structure.
How Does Illinois’s Zero Tolerance Law Apply to Drivers Under 21?
Illinois enforces a zero-tolerance policy for drivers under 21, meaning any detectable BAC — not just 0.08% — can result in a license suspension under 625 ILCS 5/11-501.8. A BAC between 0.00% and 0.08% for an underage driver results in a three-month license suspension on a first offense. A BAC of 0.08% or higher triggers the full DUI statute with all associated adult penalties plus the extended two-year revocation for underage drivers.
Frequently Asked Questions: Illinois DUI Laws and Insurance
How much does car insurance increase after a DUI in Illinois?
Illinois auto insurance premiums increase substantially after a DUI conviction. According to the Insurance Information Institute (III, 2024), driving record is one of the most significant factors in setting premium, and a DUI specifically produces among the largest increases of any single rating factor. The exact increase depends heavily on your insurer, prior driving record, the county where the DUI occurred, and your coverage level — published percentage figures vary widely by source, so getting a direct quote from a high-risk specialist is the most reliable way to know your actual cost. Some standard market insurers will non-renew your policy entirely after a DUI, forcing you into the non-standard (high-risk) market, where premiums are higher but coverage remains legally available.
How long do I need an SR-22 in Illinois after a DUI?
Illinois requires SR-22 filings for a minimum of three years following a DUI-related license revocation under 625 ILCS 5/7-601. The three-year clock begins on the date your driving privileges are reinstated — not the date of your arrest or conviction. Any lapse in coverage during those three years, even for a single day, can reset the clock entirely, and the Illinois Secretary of State will be notified immediately by your insurer. Drivers with multiple DUI convictions may face extended SR-22 requirements beyond three years. You can check your SR-22 filing status in Illinois to confirm your current compliance standing.
Can I drive during a statutory summary suspension in Illinois?
Yes, but only with a Monitoring Device Driving Permit (MDDP) and a BAIID-equipped vehicle. Illinois allows first-time DUI offenders subject to a statutory summary suspension to apply for an MDDP, which permits driving for any purpose — work, school, medical appointments — as long as the BAIID is installed and functioning. The MDDP is not available to drivers who have a prior DUI-related suspension or revocation on their record. Drivers caught driving during a suspension without an MDDP face an additional mandatory extension of their suspension.
What is the difference between a DUI suspension and a DUI revocation in Illinois?
A suspension is a temporary withdrawal of driving privileges with a defined end date, while a revocation is an indefinite cancellation that requires a formal reinstatement process. The statutory summary suspension triggered by a DUI arrest (six months for a failed test, 12 months for a refusal) ends automatically. The revocation imposed after a court conviction does not end automatically — it requires the driver to petition the Illinois Secretary of State, complete a drug/alcohol evaluation, and attend a hearing before privileges are restored. Both can occur from the same DUI incident, running on overlapping timelines.
What happens if I refuse a breathalyzer test during an Illinois DUI stop?
Refusing a breathalyzer test in Illinois results in an automatic 12-month statutory summary suspension on a first offense under 625 ILCS 5/11-501.1 — double the six-month suspension for a failed test. Illinois operates under implied consent law, meaning all drivers who use public roads have legally consented to chemical testing as a condition of their license. Refusal does not prevent a DUI prosecution; prosecutors can use the refusal itself as evidence. Drivers who refuse are also ineligible for the MDDP during their suspension period, meaning no driving at all for 12 months unless the suspension is successfully challenged at a hearing.
Can a DUI be expunged from my Illinois driving record?
No. Illinois law does not allow DUI convictions to be expunged from a driving record under any circumstances, regardless of how much time has passed. This is distinct from a criminal record expungement — while some DUI arrests without conviction may be eligible for criminal record sealing, the driving record maintained by the Illinois Secretary of State is permanent. Insurance companies and employers who conduct driving record checks will see a DUI conviction indefinitely. The practical insurance impact diminishes after roughly five years as most insurers limit their rate surcharge lookback period, but the record itself does not disappear.
What happens if my SR-22 insurance lapses in Illinois?
If your SR-22 insurance lapses, your insurer is legally required to notify the Illinois Secretary of State immediately by filing an SR-26 form, which cancels your SR-22 certification. The Secretary of State will then suspend your driving privileges again. The three-year SR-22 requirement clock can reset, meaning you may need to restart the entire three-year period from the date you reinstate coverage. Maintaining continuous, uninterrupted coverage for the full three-year period is the most reliable way to satisfy the requirement without complications.
What is aggravated DUI in Illinois and how is it different from a standard DUI?
An aggravated DUI in Illinois is a felony-level DUI charge triggered by specific circumstances, as opposed to a standard first or second DUI which are Class A misdemeanors. Aggravating factors include a BAC of 0.16% or higher, the presence of a child under 16 in the vehicle, causing bodily harm to another person, driving in a school speed zone, and operating without a valid license or insurance at the time of arrest. An aggravated DUI carries a minimum Class 4 felony classification (1–3 years in prison), rising to Class 2 or Class 1 felony depending on the severity of harm caused. Insurance consequences are more severe, and some insurers will decline to cover drivers with felony DUI convictions entirely.
