Illinois speeding ticket fines range from $120 to $310+ depending on how far over the limit you're traveling, with a critical threshold at 26+ mph over: exceeding the speed limit by 26-34 mph is a Class B misdemeanor (up to $1,500 fine and 6 months in jail), and 35+ mph over is a Class A misdemeanor (up to $2,500 fine and 1 year in jail). Construction zone violations automatically double the fine, and Illinois uses automated speed cameras in Chicago and designated safety zones. The state operates on a points-free system — instead of points, the Illinois Secretary of State tracks convictions and can suspend your license after three moving violations in 12 months. Court supervision (a form of deferred adjudication) is available for most first-time offenders and keeps the conviction off your record.

Frequently Asked Questions
How much is a speeding ticket in Illinois?
Base fines: 1-20 mph over $120-$160, 21-25 mph over $160-$310. Add court costs ($50-100) and county assessments ($20-50) for a total of $190-$460 on petty offenses. Going 26-34 mph over is a Class B misdemeanor with up to $1,500 in fines. 35+ mph over is a Class A misdemeanor with up to $2,500 in fines and up to 1 year in jail. Construction zones double the fine.
Does Illinois use a points system for speeding?
No. Illinois does NOT have a traditional points system. Instead, the Secretary of State tracks all traffic convictions. Three moving violations within 12 months can result in license suspension. For drivers under 21, the threshold is just two violations. This makes every speeding conviction significant — there's no 'point cushion' to absorb minor tickets.
What is court supervision in Illinois?
Court supervision is a form of disposition unique to Illinois where you plead guilty but the conviction is not entered on your record if you meet certain conditions (usually paying the fine and avoiding further violations for a set period). It's available for most petty traffic offenses if you haven't received supervision in the past 12 months. Court supervision does NOT report to the Secretary of State as a conviction, protecting your driving record and insurance rates.
Can I fight a Chicago speed camera ticket?
Yes, but the process differs from officer-issued tickets. Chicago speed cameras issue administrative violations (not moving violations) with fines of $35 for 6-10 mph over and $100 for 11+ mph over in safety zones. You can contest by mail, online, or in person at the Department of Administrative Hearings. Camera tickets do NOT go on your driving record and do NOT affect insurance, but unpaid tickets can result in vehicle boot or registration hold.
What happens if I speed in a construction zone in Illinois?
Illinois doubles speeding fines in construction zones under Scott's Law — even when workers are not present if signs are posted. A 15 mph over ticket that would normally be $160 becomes $320. Going 26+ mph over in a construction zone is automatically a Class A misdemeanor (up to $2,500 fine and 1 year in jail). Illinois also has automated speed cameras in active construction zones on highways. A second construction zone offense within 2 years results in a mandatory 90-day license suspension.
