In Illinois, a DUI conviction stays on your record for life. There is no waiting period, no automatic expiration, and no way to erase it through expungement or sealing. That is the short answer to how long a DUI stays on your record in Illinois: forever, on both your driving history kept by the Secretary of State and your criminal history kept by the courts and law enforcement. The only narrow exception is an arrest that did not end in a conviction or supervision.
Why Illinois Keeps DUIs on Your Record Permanently
A conviction under 625 ILCS 5/11-501 becomes a fixed entry with no built-in sunset date. Illinois does not use a “washout” period the way some other states do, where old DUIs stop counting after a set number of years. A DUI from your twenties still counts against you in your sixties, whether the question is a background check or a new criminal charge.
The record lives in two places, and each affects a different part of your life. The Illinois Secretary of State keeps your driving record, which includes convictions, suspensions, revocations, and crash involvement.1FindLaw. Illinois Code 625 ILCS 5/2-123 A first DUI conviction triggers a minimum one-year revocation of driving privileges, and the Secretary of State must revoke the license of anyone convicted under Section 11-501.2Illinois General Assembly. Illinois Code 625 ILCS 5/6-205 – Mandatory Revocation Courts, law enforcement, and in some cases insurers can see it.
Your criminal record is separate. It documents the conviction itself, classified as a misdemeanor or felony depending on the circumstances, and it is what surfaces on standard background checks used by employers, landlords, and licensing boards.
Court Supervision Avoids a Conviction but Still Stays
Some first-time DUI defendants receive court supervision rather than a conviction. If you complete supervision successfully, Illinois treats it as a dismissal without an adjudication of guilt, so it does not count as a conviction for legal purposes, and the general public will not see it as one on a standard background check.3Illinois General Assembly. Illinois Code 730 ILCS 5/5-6-3.1 – Incidents and Conditions of Supervision
Here is the catch. The DUI arrest and the supervision disposition still cannot be sealed or expunged. The Criminal Identification Act specifically names Section 11-501 supervision among the records it prohibits from being cleared.4Justia Law. Illinois Code 20 ILCS 2630/5.2 – Expungement and Sealing Law enforcement, courts, and the Secretary of State can still see it. Supervision is a better outcome than a conviction, but it does not give you a clean slate.
Supervision is also a one-time option for DUI. If you have already used it, you are ineligible for it on any later DUI charge, and the court must enter a conviction the second time around.
When a DUI Record Can Be Cleared
The permanence rule applies to convictions and supervision dispositions. If your DUI charge was dismissed or you were found not guilty, the arrest record itself is eligible for expungement. You can petition the court to have the arrest record destroyed and removed from public view. That is the only routine path to clearing a DUI-related record.
For a conviction, the only remaining route is a pardon from the Governor of Illinois. A pardon does not automatically erase the conviction, but it can restore certain rights and open the door to petitioning for expungement afterward. Gubernatorial pardons for DUI are rare and require substantial documentation. For most people this is not a realistic option.
Illinois law bars expungement and sealing for any DUI record regardless of how old it is, and the ban treats a first offense identically to a fifth for record-clearing purposes.4Justia Law. Illinois Code 20 ILCS 2630/5.2 – Expungement and Sealing
How a Permanent Record Affects a Future DUI Charge
The single most consequential effect of the permanence rule is that every prior DUI counts if you are ever charged again. There is no time limit on how far back the state can reach. A first offense is a Class A misdemeanor with up to a year in jail and a maximum fine of $2,500. A second is still a Class A misdemeanor but adds a mandatory minimum of five days in jail or 240 hours of community service. A third jumps to a Class 2 felony. A fourth removes probation as a sentencing option. A fifth is a Class 1 felony, and a sixth or later is a Class X felony. A BAC of 0.16 or higher, or transporting a child under 16, layers additional mandatory fines and jail time on top.5Illinois General Assembly.

Consequences That Don’t Expire
Because the record itself has no expiration date, the collateral consequences attached to it do not either.
Ignition Interlock
A second or subsequent DUI conviction requires an ignition interlock device on every vehicle you own for at least five years. You pay a monthly fee of up to $30 to the Secretary of State’s DUI Administration Fund, plus installation and lease costs from the device provider, which typically run $85 to $110 per month. First-time offenders seeking a restricted driving permit during revocation may need one too.2Illinois General Assembly. Illinois Code 625 ILCS 5/6-205 – Mandatory Revocation
SR-22 Insurance
After a DUI-related suspension or revocation, you must file an SR-22 certificate of financial responsibility and maintain it for three years. If the policy lapses or the SR-22 is canceled early, the Secretary of State is notified and your driving privileges are suspended again.6Illinois Secretary of State. Financial Responsibility and SR-22 SR-22 policies typically cost substantially more than standard insurance because the filing classifies you as a high-risk driver.
Professional Licensing
Licensing boards in fields like healthcare, law, finance, and education commonly require you to report criminal arrests or convictions. Some demand immediate notification; others ask at renewal. A permanent DUI means the question comes up every renewal cycle for the rest of your career. Failing to disclose is often treated as dishonesty, and boards may respond with reprimand, mandatory treatment, suspension, or revocation.
Entry to Canada
Since December 2018, Canadian law classifies impaired driving offenses as “serious criminality” because the maximum sentence for impaired driving under Canadian law was raised to ten years. A border officer can deny entry based on a DUI conviction regardless of how long ago it occurred. Options exist, including a Temporary Resident Permit for short-term entry and Criminal Rehabilitation once five years have passed since you completed every part of your sentence, but the restriction itself does not expire on its own.
The Bottom Line on Timing
The answer to how long is forever. A conviction stays on your Illinois driving and criminal records for life. Supervision keeps the word “conviction” off your public background check but still cannot be sealed or expunged. Only an arrest that ended in dismissal or acquittal can be cleared. Everything else, including the way old DUIs escalate the penalties for any new charge, follows you without an expiration date.
