Understanding Speeding Fines in Illinois

Illinois has some of the highest base speeding fines in the Midwest, and the mandatory 6-month suspension for going 31+ mph over makes aggressive speeding extremely costly. The Chicago metropolitan area has intensive enforcement through both traditional patrols and speed camera systems in school and park zones introduced in recent years.

In Illinois, going 10 mph over the speed limit on a highway typically results in an estimated fine of $275–$385, including court costs and administrative fees. The fine increases to approximately $325–$455 for 20 mph over and $375–$525 for 30 mph over. Road type significantly affects your total: fines in school zones are multiplied by 2.5×, and construction zone fines are doubled.

A Illinois speeding ticket consists of a base fine of $75 plus $5/mph over the limit, with an additional $150 in court costs and administrative surcharges. For example, going 15 mph over the speed limit would cost approximately $300 before road-type multipliers are applied. These figures reflect typical statewide fine schedules; exact amounts vary by county.

Key Illinois Speeding Laws

• Going 31 mph or more over the posted limit in Illinois results in a mandatory minimum 6-month license suspension — there is no judicial discretion to avoid it.

• Fines are doubled in construction and school zones, and a third school zone violation within 12 months triggers mandatory reporting to the Secretary of State for review.

• Illinois uses a merit-based point system: 26–34 mph over the limit adds the maximum 55 demerit points, with suspension triggered at 110 points in 12 months.

License Points in Illinois

Illinois uses a point system to track driver violations. A standard speeding infraction typically adds 2–4 points to your Illinois license depending on the severity. Accumulating 15 or more points within 2 years triggers a license suspension or mandatory DMV hearing.

Beyond license points, a speeding conviction in Illinois typically raises auto insurance premiums by 20–35%, with the surcharge lasting 3–5 years. The total long-term financial impact of a single speeding ticket — including fines, court costs, and insurance — commonly exceeds $1,000–$1,500 over the surcharge period.

Tips for Illinois Drivers

For violations under 26 mph over the limit in Illinois, court supervision — where you pay fines but the offense is not reported to the Secretary of State — is frequently available for first-time offenders. Court supervision costs slightly more than a standard guilty plea but prevents points from appearing on your Illinois driving record.

If you are stopped for speeding in Illinois, be polite and cooperative with the officer. Anything you say can be referenced in court. Before paying a ticket online, consider whether contesting it or requesting traffic school produces a better financial outcome — the insurance savings over 3–5 years typically far exceed the inconvenience of a court appearance.
