Key Takeaways

• Appear on time at the correct courthouse. Most Cook County traffic cases are handled at the Clemente Ruiz Courthouse (55 East 1st Street, Chicago) or the Hubert H. Humphrey Courthouse (400 North State Street, Chicago). Appearing at the wrong location can result in a bench warrant.
• Bring the right documents or face dismissal risk. You must bring your citation, proof of insurance, valid driver's license, and any evidence (photos, witness statements, repair receipts) to every court appearance.
• Choose your plea carefully before your first appearance. A guilty plea triggers fines and points on your license. A not-guilty plea preserves your right to contest the charge and may open the door to mitigation or a reduced offense.
• Cook County offers probationary licenses for certain suspensions. If your driving privileges are at risk, ask the judge about a Probationary Driver's License or Restricted Driving Permit before your case is resolved.
• You may qualify for supervision or Court-Ordered Traffic School. First-time offenders and those charged with minor violations can often negotiate supervised disposition, which keeps the violation off your permanent driving record.
• The cost of ignoring a citation is far higher than defending it. Failure to appear results in automatic license suspension, a $100 late fee (plus additional penalties), and a bench warrant under Illinois Vehicle Code 625 ILCS 5/6-303.
