DuPage County DUI Records Search

DuPage County DUI records are filed and maintained through the 18th Judicial Circuit Court in Wheaton. The county consistently ranks among the top in Illinois for DUI enforcement activity, with municipalities like Naperville, Wheaton, and Lombard generating a high volume of cases each year. If you need to find a DUI case, check a court disposition, or look up an arrest record in DuPage County, this page covers the key offices and access methods available to you.

DuPage County Circuit Clerk

Circuit Clerk Theresa Barreiro oversees court records for the 18th Judicial Circuit, which serves DuPage County exclusively. The clerk's office at 505 N. County Farm Rd. in Wheaton handles all case filings, dispositions, and records requests. DUI cases are classified as traffic or criminal depending on the offense level, and the clerk maintains both types of records.

First-offense DUI under 625 ILCS 5/11-501 is a Class A misdemeanor. A conviction carries up to one year in jail, a fine up to $2,500, and a one-year license revocation. A second offense adds a mandatory 5 days in jail or 240 hours of community service and a 5-year revocation. DuPage County courts see many first and second offenders from its densely populated suburbs, and all of those convictions stay in the Circuit Clerk's records permanently.

Note: DUI convictions cannot be expunged or sealed under Illinois law at 20 ILCS 2630/5.2, so DuPage County DUI case records remain accessible indefinitely.

DuPage County Sheriff

The DuPage County Sheriff handles law enforcement in unincorporated parts of the county and assists with countywide enforcement. Arrest records for DUI incidents in those areas go through the Sheriff's office at 501 N. County Farm Rd. in Wheaton.

For cities like Naperville, Wheaton, and Lombard, local police departments handle DUI stops and maintain their own arrest records. You would contact each city's police department directly for arrest-level records, while the Circuit Clerk holds the court case records for all DuPage County municipalities.

Under the Illinois Freedom of Information Act at 5 ILCS 140, arrest reports are public record and must be provided within 72 hours of a request. Each law enforcement agency in DuPage County processes its own FOIA requests for arrest-level records. Court records at the Circuit Clerk's office are accessed separately through that office's records request process.

When a DUI arrest is made in DuPage County, the driver faces both criminal court proceedings and a separate administrative action from the Illinois Secretary of State. Refusing a chemical test at the scene triggers a Statutory Summary Suspension under 625 ILCS 5/11-501.1, independent of the court outcome. A first-time refusal leads to a 12-month suspension; failing the test means 6 months. These suspensions run separately from any revocation ordered after conviction.

The Illinois State Police Bureau of Identification at isp.illinois.gov/BureauOfIdentification maintains the statewide criminal history database. A DuPage County DUI conviction will appear in this database and is accessible through the ISP's public criminal history request process. The ISP can be reached at 815-740-5160 or ISP.BOI.Customer.Support@illinois.gov.

The Illinois State Police criminal history system at isp.illinois.gov/BureauOfIdentification/CriminalHistory shows what DUI conviction data is available through the state system for DuPage County and other Illinois counties.

DUI Evaluations and License Reinstatement

Anyone convicted of DUI in DuPage County must complete a substance abuse evaluation through a provider licensed by the Illinois Division of Substance Use Prevention and Recovery. The court's designated agency handles initial evaluations, and defendants may complete required education or treatment with any SUPR-licensed provider after that first evaluation.

License revocation follows automatically after a DUI conviction under 625 ILCS 5/6-205. Getting your license back requires a formal hearing with the Illinois Secretary of State. DuPage County drivers can access Secretary of State administrative hearing services through the main office or by mail. The SOS driving record purchase portal at ilsos.gov lets you get a copy of your driving record, which will reflect any DUI-related suspension or revocation.

Note: The Secretary of State's administrative hearing process is separate from the criminal court process and must be handled independently of your DuPage County court case.
