Lake County, Illinois, has about 719,000 residents (2024 Census Bureau estimate). A traffic ticket written in Lake County is a court case in the Circuit Court of Lake County, and the conviction it ends in goes on the driving record kept by the Illinois Secretary of State. This guide says which court takes the ticket, who writes them and where the driving record lives.
This guide covers where tickets go, who writes them, the driving record, cities and common questions.

Where a Ticket Written in Lake County Goes
Tickets in Lake County go to the Circuit Court of Lake County. A paid ticket, a dismissal and a trial all end up in that court's records.
For Lake County, SearchSystems opened and checked the court records page for the county at ilsos.gov/departments/archives/databases/lake.html (page title: Lake County Circuit Court Case Files Index (1840-1898)), phone 815-753-1807, which answered when SearchSystems opened it on September 23, 2026.
Illinois has no single public index of every trial court case; each court's records are looked up through that court.
Who Writes the Tickets in Lake County
The Lake County Sheriff's Office and the agencies that report for Waukegan, Buffalo Grove, Mundelein, Highland Park, North Chicago, Gurnee and 27 more cities write the traffic tickets in Lake County.
The FBI's agency list also places one campus police department and three other agencies in Lake County (the arrest records guide names each one).
The Barrington Police Department, the Island Lake Police Department, the Fox River Grove Police Department and one more are each listed by the FBI across several counties including Lake County, so their arrests are not broken out for Lake County here.
The Driving Record and the Illinois Secretary of State
Convictions are reported by the court to the Illinois Secretary of State, which keeps the driving record and decides on points and suspensions. Order the driving record from that agency, not from the court.
Paying a ticket is a conviction, reported to the Illinois Secretary of State like any other; contesting it means a plea of not guilty entered with the court by the date on the ticket.
A DUI is a criminal charge rather than a ticket, with its own license case before the Secretary of State (see Lake County DUI).
Cities in Lake County
Wherever in the county a ticket is written, it is answered in the Circuit Court of Lake County.
