Naperville DUI records come primarily from the Naperville Police Department for arrest data and from the 18th Judicial Circuit Court in DuPage County for all case filings and court dispositions. Naperville sits mainly in DuPage County, with a smaller portion in Will County, so the handling county for a specific DUI case depends on where in the city the arrest took place.

Illinois State Police Records for Naperville DUI Cases
Every Naperville DUI arrest results in a fingerprint submission to the Illinois State Police Bureau of Identification. When the circuit court reports a conviction, the ISP links that outcome to the fingerprint record. The ISP then holds a statewide criminal history that includes all Naperville DUI arrest and conviction data. Under 20 ILCS 2630/5.2, DUI convictions in Illinois cannot be expunged or sealed. This rule covers every Naperville DUI conviction in the ISP system, with no exceptions.
The ISP Bureau of Identification at isp.illinois.gov/BureauOfIdentification is the central state repository for all Illinois DUI criminal history, including records generated by Naperville DUI cases handled through the 18th Judicial Circuit.
Conviction data is public under the Uniform Conviction Information Act. The ISP criminal history request page at isp.illinois.gov/BureauOfIdentification/CriminalHistory explains how to submit a request for a criminal history that includes Naperville DUI conviction data.

Driving Record and License Actions for Naperville DUI Cases
A DUI conviction from a Naperville case triggers mandatory license revocation by the Illinois Secretary of State. The SOS handles revocation as an administrative process that runs separately from the criminal court case. Reinstatement requires a formal hearing with the SOS, and waiting periods vary based on the number of prior DUI convictions on the driver's Illinois record.
The Statutory Summary Suspension applies before the criminal case is resolved. If a driver fails or refuses a chemical test during a Naperville DUI stop, the suspension takes effect 46 days after the officer issues the notice. Refusing the test on a first offense means a 12-month suspension. Failing the test on a first offense means a 6-month suspension. Drivers can challenge the suspension through a formal SOS administrative hearing. More on that process is at ilsos.gov/departments/administrative-hearings.html.
Driving record abstracts that show Naperville DUI convictions, suspensions, and revocations are available from the SOS at ilsos.gov. The abstract costs $20 and covers the full license action history on a driver's Illinois record, including any actions tied to Naperville DUI cases.
Naperville DUI Enforcement and What the Records Cover
Naperville is one of the more active DUI enforcement cities in Illinois on a per-capita basis, and NPD runs dedicated patrols and participates in statewide enforcement campaigns throughout the year. The high volume of DUI stops in Naperville means the 18th Judicial Circuit processes a significant number of Naperville DUI cases each year, and the clerk's records reflect a range of charge types from standard first-offense misdemeanors to felony repeat-offense cases.
The records from a Naperville DUI case are spread across different agencies. The NPD holds the arrest-level records. The DuPage County Circuit Clerk holds the court case records. The ISP holds the statewide conviction history. The SOS holds driving record and license action data. Each agency maintains a different piece of the record, and working through them in sequence is the most thorough approach when researching a specific Naperville DUI matter.
The Illinois Courts website at illinoiscourts.gov/courts/circuit-court has background on how the 18th Judicial Circuit operates and how DUI cases move from filing through final disposition. This is useful context before contacting the DuPage County Clerk or consulting an attorney about a Naperville DUI case.
