The DUI Law in Illinois
Drunk driving is charged as DUI in Illinois, at a blood alcohol level of 0.08 or more.
Driving in Illinois is consent to a breath or blood test when an officer has cause to suspect DUI; the license case that follows a refusal or a failed test is run by the Secretary of State, separately from the criminal case.
Illinois sets no time limit on prior offenses: every earlier conviction counts toward a repeat charge.
Who Makes DUI Arrests in Macon County
The Macon County Sheriff's Office and the agencies that report for Decatur, Mount Zion, Maroa, Blue Mound and Warrensburg make the DUI arrests in Macon County.
The FBI's agency list also places two other agencies and two campus police departments in Macon County (the arrest records guide names each one).
Together, the three agencies in Macon County with all twelve months of 2025 on file reported 4,153 arrests to the FBI that year, all offenses together; the FBI's count for Macon County does not break DUI out.
Booking After a DUI Arrest in Macon County
A driver arrested for DUI and kept in custody goes to the county jail, whichever agency made the arrest. The jail, run by the Macon County Sheriff's Office, held about 320 people on an average day in 2023 by the Vera Institute of Justice's count and has a jail page SearchSystems verified at sheriff-macon-il.us/corrections. The Macon County inmate search guide covers the jail in full.
The Court Case
The State's Attorney files the charge, and the case is heard in the Circuit Court of Macon County.
The State's Attorney's page SearchSystems verified is at maconcounty.illinois.gov, phone (217) 624-4312.
The court records page SearchSystems verified for the county is at apps.ilsos.gov/isairad/maconsrch.jsp.
Illinois has no single public index of every trial court case; each court's records are looked up through that court.
The License Case
The court case is only half the record. The Secretary of State runs a separate administrative case over the license, which can suspend it before the criminal case is decided, and the Illinois Secretary of State keeps the driving record the conviction goes on.
The Records a DUI Leaves
- The arrest report: from the agency that made the arrest, under the Illinois Freedom of Information Act.
- The court file: from the Circuit Court of Macon County, kept by the Circuit Clerk.
- The driving record: from the Illinois Secretary of State.
