A first-offense DUI in Illinois means a mandatory one-year license revocation, fines up to $2,500, and three years of required SR-22 filing under 625 ILCS 5/6-205. Illinois law defines DUI under 625 ILCS 5/11-501 as operating a vehicle at a 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 — a DUI 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 a Class A Misdemeanor, carrying up to 364 days in jail, fines up to $2,500, and a mandatory one-year license revocation. Drivers under 21 face a two-year revocation on a first offense. A third DUI becomes a Class 2 Felony — punishable by 3 to 7 years in prison — and results in a 10-year license revocation.
| Offense | Classification | Max Jail | License Revocation | Max Fine |
|---|---|---|---|---|
| 1st offense | Class A Misdemeanor | 364 days | 1 year (2 yrs under 21) | $2,500 |
| 2nd offense | Class A Misdemeanor | 364 days | 5 years (within 20 yrs) | $2,500 |
| 3rd offense | Class 2 Felony | 3–7 years | 10 years | $25,000 |
| Aggravated DUI | Class 4 Felony (min) | 1–3 years | Varies | $25,000 |

What Is a Statutory Summary Suspension in Illinois?
A statutory summary suspension is an automatic, administrative suspension 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. This is separate from any court-ordered penalty. First-time DUI offenders may be eligible for a Monitoring Device Driving Permit (MDDP), which allows limited driving during the suspension period if a BAIID is installed. The MDDP is not available to drivers with prior DUI-related suspensions or revocations.
What Is the Difference Between a DUI Suspension and a Revocation?
A suspension is a temporary withdrawal of driving privileges with a defined end date — it expires automatically. A revocation is a court-imposed cancellation that requires a formal reinstatement hearing before the Illinois Secretary of State. Revocations for a first DUI last a minimum of one year under 625 ILCS 5/6-205. Reinstating after a DUI-related revocation costs $500, while reinstating after a first-offense summary suspension costs $250, according to the Illinois Secretary of State’s fee schedule. Both processes can apply to the same DUI incident, running on overlapping timelines.
What Is a BAIID and When Is It Required?
A Breath Alcohol Ignition Interlock Device (BAIID) prevents a vehicle from starting if the driver’s BAC exceeds 0.025%. BAIID installation is mandatory for any driver seeking an MDDP during a summary suspension or a Restricted Driving Permit (RDP) during a revocation period. According to the Illinois Secretary of State’s BAIID fee schedule, vendor installation costs range from $70 to $480, with monitoring fees of $15 to $70 per visit. The state also charges a separate $30 monthly MDDP monitoring fee plus an $8 permit fee, paid directly to the Secretary of State’s office.
How Does a DUI Affect Your Auto Insurance in Illinois?
A DUI conviction triggers an SR-22 filing requirement and substantially higher insurance premiums 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 premiums, and a DUI specifically produces among the largest increases of any single violation. Many standard carriers will non-renew your policy after a DUI, pushing you into the non-standard market where coverage is available but premiums are higher.
What Is an SR-22 and Why Do DUI Drivers Need One?
An SR-22 is a Certificate of Financial Responsibility — filed by your insurer directly with the Illinois Secretary of State — confirming you carry at least the state minimum liability coverage of $25,000/$50,000/$20,000. It is not a type of insurance policy; it is a filing attached to an existing policy. Under 625 ILCS 5/7-601, Illinois requires SR-22 filings for a minimum of three years following a DUI conviction. Any lapse in coverage — even one day — can restart that clock. See the full breakdown of Illinois minimum car insurance requirements to understand what your policy must include before an SR-22 can be filed.
How Long Does a DUI Stay on Your Insurance Record?
A DUI conviction remains on your Illinois driving record permanently, but most insurers look back three to five years when calculating premiums (III, 2024). The practical insurance impact is most severe in years one through five, with premiums gradually stabilizing after the SR-22 requirement ends — assuming no additional violations occur. Illinois does not allow DUI convictions to be expunged from your driving record. For how Illinois law distinguishes these terms, see DWI vs. DUI in Illinois.
What Are the Steps to Reinstate Your License After a DUI in Illinois?
Reinstating an Illinois driver’s license after a DUI revocation requires completing a specific sequence. 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 assesses your risk classification (minimal, moderate, significant, or dependent).
- Complete any recommended treatment. Drivers classified above “minimal risk” must complete a corresponding program before reinstatement is granted.
- File proof of SR-22 insurance. Your insurer files 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 review; repeat offenders require a formal 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 Illinois Handle DUI Cases Differently?
Chicago and Cook County DUI cases are prosecuted under the same Illinois statutes but carry additional local enforcement layers. Cook County operates a dedicated DUI court system and offers a Drug Court / DUI Diversion program for 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 Illinois Have Additional DUI Penalties for 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 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), a DUI produces among the largest premium increases of any single rating factor. The exact increase depends on your insurer, prior driving record, county where the DUI occurred, and your coverage level — figures vary widely by source. Some standard market insurers will non-renew your policy entirely, forcing you into the non-standard market where coverage remains legally available but premiums are higher. Getting a direct quote from a high-risk specialist is the most reliable way to know your actual cost.
How long do I need an SR-22 after a DUI in Illinois?
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 arrest or conviction date. Any lapse during those three years can reset the clock entirely, and the Secretary of State is notified immediately. Drivers with multiple DUI convictions may face extended SR-22 requirements. You can check your SR-22 filing status in Illinois to confirm your current compliance.
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 to apply for an MDDP, which permits driving for any purpose — work, school, medical — as long as the BAIID is installed and functioning. The MDDP is not available to drivers with a prior DUI-related suspension or revocation. Drivers caught driving without an MDDP during a suspension face an additional mandatory extension of their suspension period.
What is the difference between a DUI suspension and a DUI revocation in Illinois?
A suspension is a temporary withdrawal with a defined end date that expires automatically — the statutory summary suspension (six months for a failed test, 12 months for a refusal) works this way. A revocation is an indefinite cancellation requiring a formal reinstatement process through the Secretary of State, including a drug/alcohol evaluation and a hearing. Both can occur from the same DUI incident, running on overlapping timelines.
What happens if I refuse a breathalyzer test in Illinois?
Refusing a breathalyzer 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 have legally consented to chemical testing as a condition of their license. Refusal does not prevent prosecution; prosecutors can use it as evidence of consciousness of guilt. Drivers who refuse are also ineligible for the MDDP during the suspension period.
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. This is distinct from a criminal record expungement — the driving record maintained by the Illinois Secretary of State is permanent. Insurance companies and employers will see a DUI conviction indefinitely when pulling your driving abstract. The practical insurance rate impact diminishes after roughly five years as most insurers limit their surcharge lookback period, but the record itself does not disappear.
What happens if my SR-22 insurance lapses in Illinois?
Your insurer is legally required to file an SR-26 cancellation form with the Illinois Secretary of State, which suspends your driving privileges immediately. The three-year SR-22 clock can reset entirely, meaning you may need to restart the full period from when you reinstate coverage. The cost of a lapse — new reinstatement fees, higher premiums, potential new violations from driving suspended — far exceeds the cost of maintaining continuous coverage.
What is aggravated DUI in Illinois?
An aggravated DUI is a felony-level DUI charge under 625 ILCS 5/11-501(d), triggered by: a BAC of 0.16% or higher, a child under 16 in the vehicle, bodily harm to another person, driving in a school speed zone, or operating without a valid license or insurance. An aggravated DUI carries a minimum Class 4 Felony classification (1–3 years in prison), rising to Class 2 or Class 1 depending on the severity of harm caused. Some insurers will decline to cover drivers with felony DUI convictions entirely.
