Cook County DUI Records

Cook County DUI records cover the largest court system in Illinois, handling tens of thousands of DUI cases each year across Chicago and dozens of suburban municipalities. If you need to search DUI case records, find arrest history, or look up a court disposition in Cook County, the Circuit Clerk and Sheriff maintain the primary sources. Cases are processed at multiple district courthouses depending on where the offense occurred, so knowing the right location matters when you start your search.

Cook County Circuit Clerk

The Circuit Clerk of Cook County maintains all court records, including DUI case filings, court dates, dispositions, and sentencing records. Mariyana T. Spyropoulos serves as Circuit Clerk. The main office is located downtown at 50 W. Washington, Suite 1001, Chicago. DUI traffic cases can be searched online through the clerk's web portal, but full criminal case files generally require an in-person visit or a formal records request.

The Cook County Circuit Court website at cookcountyclerkofcourt.org provides online DUI case search and court call information for Cook County.

DUI traffic cases in Cook County can be searched online through this portal, though full criminal case files require an in-person visit or a formal records request to the clerk's office.

Cook County has a unique court structure. Unlike most Illinois counties, Cook runs its own standalone circuit rather than sharing a judicial circuit with neighboring counties. This means DUI cases originating in municipalities like Cicero, Evanston, or Schaumburg all flow through the Cook County court system rather than a regional multi-county circuit. The court handles first-offense misdemeanor cases at district courthouses spread across the county, and felony DUI cases get sent to the main criminal courthouse at 26th and California in Chicago. If you're not sure which district handled a specific case, the clerk's office can point you in the right direction by case number or defendant name.

Cook County Sheriff DUI Arrests

The Cook County Sheriff's Office, led by Thomas J. Dart, handles law enforcement across unincorporated areas of the county and maintains arrest records including DUI arrests. The Sheriff's records are separate from the court's case files. For arrest reports and jail booking records, the Sheriff's office is your first stop.

The Cook County Sheriff website at cookcountysheriff.org provides information on the Sheriff's services, inmate lookup, and public safety programs for Cook County.

Inmate lookup tools on the Sheriff's site let you check whether someone is currently in custody following a DUI arrest in Cook County.

Under 5 ILCS 140, Illinois Freedom of Information Act rules require government agencies to turn over arrest reports within 72 hours of a request. Cook County has its own FOIA process for Sheriff's arrest records.

FOIA Requests for Cook County DUI Records

To request Cook County Sheriff arrest reports, you'll use the county's dedicated FOIA portal. This is distinct from the Circuit Clerk's court records. Arrest records held by the Sheriff can include the initial DUI stop report, field sobriety test notes, and booking information.

The Cook County FOIA request page at cookcountyil.gov is the starting point for submitting public records requests to the Cook County Sheriff's Office.

Submitting your request online through this portal is typically faster than a written mail request, and the county is required by state law to respond within 5 business days for most record types.

It is worth noting that court records held by the Circuit Clerk are subject to different access rules than arrest records held by the Sheriff. Under 625 ILCS 5/11-501, DUI is defined as operating a vehicle with a BAC of 0.08 or higher, or while impaired by any substance. The record of a DUI conviction stays permanently in Illinois systems and cannot be expunged or sealed under 20 ILCS 2630/5.2. Only conviction data is made public under the Uniform Conviction Information Act at 20 ILCS 2635/1; arrest-only records without a conviction have more restricted public access.

Note: DUI defendants in Cook County may also need an initial substance abuse evaluation through the court's designated agency. Contact the Cook County DUI Evaluation office at SSD.DUIeval@cookcountyil.gov or call 312-948-6001 for guidance on the evaluation requirement.

DUI Evaluations and Treatment in Cook County

Illinois law requires that anyone convicted of a DUI complete a substance abuse evaluation and, depending on results, an education or treatment program through a provider licensed by the Illinois Department of Human Services Division of Substance Use Prevention and Recovery. Cook County courts work with a designated agency for initial evaluations.

After the initial evaluation, defendants may complete required education and treatment through any SUPR-licensed provider. The Illinois State Police Bureau of Identification at isp.illinois.gov/BureauOfIdentification maintains the central criminal history database that feeds into license revocation and reinstatement processes tied to DUI convictions.

A DUI conviction under Illinois law triggers mandatory license revocation under 625 ILCS 5/6-205. Reinstatement requires a formal hearing through the Secretary of State. For drivers who refused a breath or blood test during a Cook County DUI stop, a Statutory Summary Suspension kicks in automatically under 625 ILCS 5/11-501.1. Refusing the test means a 12-month suspension for a first offense; failing it means 6 months. Second offenders face 36 and 12 months, respectively.
