A first-offense DUI in Illinois is a Class A Misdemeanor with fines up to $2,500 and a mandatory one-year license revocation under 625 ILCS 5/11-501. Aggravating factors — a BAC at or above 0.16%, a passenger under age 16, or a prior conviction — trigger enhanced mandatory minimums that courts cannot waive. Illinois law classifies a standard first DUI as a misdemeanor, but the charge escalates to a felony starting with the third lifetime offense, regardless of how many years have passed between incidents. These penalties apply statewide, though Cook County courts may layer additional sentencing weight on DUI cases involving injury or aggravated circumstances.

What Are the Penalties for a First-Offense DUI in Illinois?
A first-offense DUI in Illinois carries a fine of up to $2,500, up to 364 days in county jail, and a mandatory one-year license revocation under 625 ILCS 5/11-501. Court costs and mandatory drug/alcohol assessments typically add significantly to the base fine. The one-year revocation is separate from the Statutory Summary Suspension — an administrative action that begins 46 days after arrest if you failed or refused a chemical test.
For a first offense, the Statutory Summary Suspension runs six months for failing a breath or blood test, or 12 months for refusing one, under 625 ILCS 5/11-501.1. These two penalties run concurrently in some cases but are governed by entirely separate legal proceedings.
How Do Illinois DUI Penalties Scale With BAC and Prior Offenses?
Illinois DUI penalties increase substantially based on BAC level at the time of arrest and the number of prior DUI convictions on your lifetime record. The chart below reflects statutory minimums and maximums under 625 ILCS 5/11-501 and related sections of the Illinois Vehicle Code.
| Offense | Classification | Max Fine | Jail / Prison | License Revocation |
|---|---|---|---|---|
| 1st Offense (BAC <0.16%) | Class A Misdemeanor | $2,500 | Up to 364 days | 1 year mandatory |
| 1st Offense (BAC ≥0.16%) | Class A Misdemeanor + Enhanced | $2,500 | 100 hrs community service OR 2 days mandatory jail | 1 year mandatory |
| 1st Offense (child passenger <16) | Class 4 Felony | $25,000 | 1–3 years prison | 1 year mandatory |
| 2nd Offense | Class A Misdemeanor | $2,500 | Mandatory 5 days jail OR 240 hrs community service | 5 years minimum |
| 3rd Offense | Class 2 Felony (Aggravated DUI) | $25,000 | 3–7 years prison | 10 years |
| 4th Offense | Class 2 Felony (Aggravated DUI) | $25,000 | 3–7 years prison | Lifetime revocation |
| 5th Offense | Class 1 Felony (Aggravated DUI) | $25,000 | 4–15 years prison | Lifetime revocation |
| 6th+ Offense | Class X Felony (Aggravated DUI) | $25,000 | 6–30 years prison | Lifetime revocation |

What Does “Aggravated DUI” Mean in Illinois?
Aggravated DUI is a felony-level charge that applies when specific circumstances are present, even on a first offense. Illinois law under 625 ILCS 5/11-501(d) designates a DUI as aggravated when: it is the driver’s third or subsequent lifetime DUI; the driver caused great bodily harm or death; a child under 16 was a passenger; the driver was uninsured; the vehicle was a school bus; or the driver had no valid license. An aggravated DUI conviction cannot be expunged from an Illinois driving record.
What Happens If You Refuse a Breathalyzer in Illinois?
Refusing a chemical test in Illinois triggers an automatic 12-month Statutory Summary Suspension for a first offense and a 36-month suspension for a second or subsequent refusal, under 625 ILCS 5/11-501.1. Refusal does not prevent a DUI prosecution — prosecutors can use the refusal itself as evidence of consciousness of guilt. Illinois courts consistently treat refusal as an aggravating factor during sentencing.
What Happens to Your Driver’s License After a DUI in Illinois?
A DUI conviction in Illinois triggers two separate license actions — the Statutory Summary Suspension (administrative, begins 46 days after arrest) and the court-ordered revocation (criminal, begins at sentencing). Both are mandatory and run on separate timelines.
What Is the Difference Between a Suspension and Revocation?
A suspension has a defined end date and restores driving privileges automatically when the period expires — no hearing required. A revocation has no automatic end date; you must formally petition the Illinois Secretary of State for reinstatement, complete required evaluations and programs, pay reinstatement fees (typically $500), and in many cases appear at a formal hearing. A first DUI conviction triggers a revocation, not just a suspension. For a step-by-step guide through this process, see first-time DUI offense license reinstatement in Illinois.
Can You Drive During a DUI Suspension or Revocation in Illinois?
During a Statutory Summary Suspension, first-time offenders may be eligible for a Monitoring Device Driving Permit (MDDP), which allows limited driving if a Breath Alcohol Ignition Interlock Device (BAIID) is installed. During a revocation period, a Restricted Driving Permit (RDP) may be available for hardship purposes — but it requires a formal hearing and is not guaranteed. Driving on a revoked license is a Class A Misdemeanor under 625 ILCS 5/6-303, and if it results in a crash causing death, a Class 3 Felony.
How Does a DUI Affect Your Car Insurance in Illinois?
A DUI conviction in Illinois will substantially increase your car insurance premium, and many standard carriers will non-renew your policy entirely. According to the Insurance Information Institute (III, 2024), a DUI is among the single largest premium-driving factors for any driver profile. The premium increase typically persists for three to five years on most insurers’ rating systems, even after the SR-22 requirement ends. Some carriers use a seven-year lookback window for DUI convictions when calculating rates.
What Is SR-22 Insurance and Who Needs It After a DUI?
An SR-22 is not an insurance policy — it is a certificate of financial responsibility that your insurance company files with the Illinois Secretary of State to prove you carry state-required minimum liability coverage. After a DUI conviction, SR-22 filing is required as a condition of license reinstatement. Illinois minimum liability coverage under 625 ILCS 5/7-601 is $25,000/$50,000/$20,000. For a full breakdown see the Illinois minimum car insurance requirements guide. You can also check your SR-22 filing status in Illinois through the Secretary of State’s portal at any time.
What Steps Should You Take Immediately After a DUI Conviction?
Taking the right steps in the correct order directly affects how quickly you can legally drive again and how much your insurance will cost.
- Request a formal hearing with the Illinois Secretary of State’s office — reinstatement does not happen automatically after a DUI revocation.
- Complete a drug and alcohol evaluation from a state-approved provider, as required by the Secretary of State.
- Enroll in and complete a DUI Risk Education program or any treatment recommended by your evaluation.
- Purchase an auto insurance policy that meets Illinois minimum liability limits under 625 ILCS 5/7-601.
- Request an SR-22 filing from your insurer and confirm the certificate has been received by the Secretary of State before attempting to drive.
- Install a BAIID device if required under your MDDP or RDP conditions, through a state-approved vendor.
- Pay all reinstatement fees to the Illinois Secretary of State.

Frequently Asked Questions: Illinois DUI Penalties and Insurance
What is the minimum fine for a DUI in Illinois?
The minimum fine for a first-offense DUI in Illinois is $500, with a statutory maximum of $2,500 under 625 ILCS 5/11-501. Court costs and mandatory drug/alcohol assessments typically add significantly to the base fine. If your BAC was 0.16% or higher, or if a passenger under 16 was in the vehicle, additional mandatory minimums apply — including minimum jail time or community service that a judge cannot waive. Total out-of-pocket costs for a first DUI in Illinois, including fines, attorney fees, and reinstatement costs, can be substantial according to the Illinois Secretary of State’s DUI Fact Book (2024).
How long does a DUI stay on your driving record in Illinois?
A DUI conviction stays on your Illinois driving record permanently. Illinois does not allow DUI convictions to be expunged or sealed under 20 ILCS 2630/5.2. This means a second DUI — even 20 years after the first — is still treated as a second offense for sentencing purposes, triggering the mandatory five-day jail term and five-year minimum revocation period. Insurance companies generally look back three to five years for rating purposes, according to the Insurance Information Institute (III, 2024), but the legal record itself does not disappear.
How long do I need to carry SR-22 insurance in Illinois?
Illinois requires SR-22 insurance for a minimum of three years from the date your driving privileges are reinstated, not from the date of arrest or conviction. The exact duration is set by the Illinois Secretary of State based on your specific offense. If your policy lapses at any point, your insurer must notify the state immediately, your license is suspended again, and the three-year clock may restart. See the Illinois SR-22 lapse guide for full details on what happens if coverage drops.
What happens if I drive during a DUI-related suspension in Illinois?
Driving on a suspended or revoked license in Illinois is a Class A Misdemeanor under 625 ILCS 5/6-303, carrying up to 364 days in jail and a fine of up to $2,500. If you cause a crash resulting in great bodily harm while driving on a DUI-related revocation, the charge escalates to a Class 4 Felony. If the crash causes death, it becomes a Class 3 Felony. Any new conviction while suspended or revoked also extends the original suspension or revocation period and resets the SR-22 requirement timeline.
Can I get car insurance after a DUI in Illinois?
Yes — Illinois law prohibits insurers from refusing minimum liability coverage to any licensed Illinois driver. After a DUI, you will likely need to obtain coverage through the non-standard (high-risk) insurance market, which includes carriers that specialize in DUI and SR-22 drivers. Standard carriers may non-renew your policy, but non-standard carriers fulfill both the state’s minimum coverage requirement and the SR-22 filing obligation simultaneously. Premiums will be significantly higher but coverage remains accessible regardless of DUI history.
What is the difference between a DUI suspension and a DUI revocation in Illinois?
A suspension has a defined end date and restores driving privileges automatically — no hearing required. A revocation has no automatic end date; you must formally petition the Secretary of State for reinstatement, complete required evaluations and programs, and in many cases appear at a formal hearing. A first DUI conviction triggers a revocation. The Statutory Summary Suspension that begins 46 days after arrest is separate, does expire automatically, but does not restore privileges lost under the criminal revocation.
What is an Aggravated DUI in Illinois?
An Aggravated DUI in Illinois is a felony-level DUI charge under 625 ILCS 5/11-501(d), applying when specific statutory factors are present: a third or subsequent lifetime DUI, causing great bodily harm or death, a passenger under age 16, driving without a valid license or insurance, operating a school bus, or driving in a school zone. Aggravated DUI cannot be expunged and carries mandatory prison terms rather than county jail time. Even a first-time DUI can be charged as aggravated if any of these factors are present.
How do I find SR-22 insurance in Illinois after a DUI?
After a DUI, focus your search on non-standard insurance carriers that specialize in high-risk drivers and SR-22 filings. Standard carriers like State Farm or Allstate may non-renew your policy, but they are not your only option. Independent agencies that work with multiple non-standard carriers can compare rates across several insurers simultaneously — typically producing better pricing than going directly to a single company. Confirm that your insurer can file the SR-22 electronically with the Illinois Secretary of State. Call 773-202-5060 or get a free quote online for same-day assistance.
