What you'll pay for a speeding ticket in Illinois
Illinois speeding fines depend on how far over the limit you were driving and whether the violation happened in a school or construction zone. A ticket for driving 1 to 10 miles per hour over the limit costs $120. For 11 to 20 mph over, you pay $140. The fine jumps to $200 for 21 to 30 mph over the limit, and $375 for 31 to 40 mph over. Anything 41 mph or faster over the posted limit costs $500 or more.
These base fines are not the only cost. Illinois adds court fees, which typically run $75 to $100 depending on the county. You may also face a Driver Responsibility Assessment fee of $250 if this is your first violation, or $375 if you have prior violations within a certain period. The total bill often lands between $400 and $700 for a routine speeding ticket.
Fines are higher in school zones and construction zones. School zone violations double the base fine. Construction zone violations also increase the penalty, though the exact amount varies by county. If you were speeding in both a school and construction zone simultaneously, the fine applies only once — you do not pay both multipliers.

How fines increase with speed over the limit
Illinois structures speeding fines in bands based on how much you exceeded the posted limit. The state does not use a per-mile-per-hour calculation; instead, it groups violations into ranges. This means the difference between 10 mph over and 11 mph over the limit is significant — it moves you from the $120 band into the $140 band.
The bands are: 1–10 mph over ($120), 11–20 mph over ($140), 21–30 mph over ($200), 31–40 mph over ($375), and 41 mph or faster over ($500 or more). If you were clocked at 35 mph in a 25 mph zone, you were 10 mph over, so the base fine is $120. If you were clocked at 36 mph in the same zone, you were 11 mph over, and the base fine becomes $140. Courts have no discretion to lower these amounts — the fine is set by statute once the speed is recorded.
School zone and construction zone penalties
Speeding in a school zone carries a doubled fine. If your base fine would have been $120, it becomes $240 in a school zone. The doubling applies to the base fine only, not to court fees or the Driver Responsibility Assessment. School zones are typically marked with signs and are active during school hours — usually 7 a.m. to 4 p.m. on school days, though this varies by district.
Construction zones have their own penalty structure. Illinois increases the fine by 50 percent in active construction zones where workers are present. A $120 base fine becomes $180. Unlike school zones, construction zone penalties explore only when construction is actively happening and workers are in the zone — not straightforward because a construction zone sign is posted. The officer must document that the zone was active at the time of the violation.
Court fees and additional assessments
Beyond the base fine, Illinois counties add court fees to process your ticket. These fees typically range from $75 to $100 and go to the county court system, not to the state. The exact amount depends on which county issued the ticket. Some counties charge $75; others charge closer to $100. You can call the courthouse listed on your ticket to find out the specific fee for your county.
The Driver Responsibility Assessment is a separate state fee. For a first violation, it is $250. If you have had another violation within the past five years, the fee increases to $375. This fee is not optional and does not go away if you pay the ticket — it is assessed automatically by the Secretary of State's office. If you do not pay it, your driver's license can be suspended.
What happens if you pay late or miss a court date
If you do not pay your fine by the due date, the court adds a failure-to-pay penalty, typically $100 to $200 depending on the county. Your license can also be suspended for non-payment. If you miss a court date without notifying the court, a warrant can be issued for your arrest, and additional charges may be filed.
If you received a ticket and are unsure of the due date, check the ticket itself — the date is printed on it. If you cannot pay by that date, contact the courthouse listed on the ticket and ask about a payment plan. Most Illinois courts allow you to pay in installments rather than in a lump sum, which prevents late fees and suspension.
How speeding tickets affect your insurance and license
A speeding conviction in Illinois is reported to your insurance company and typically raises your premium. The increase depends on your insurer and your driving history, but a single speeding ticket often results in a 10 to 15 percent premium increase for three years. Multiple violations within a short period can trigger a larger increase or even policy cancellation.
Speeding violations also add points to your driving record. Illinois uses a points system where violations are assigned point values. A speeding ticket is usually worth 5 points. If you accumulate 15 or more points within a two-year period, your license can be suspended. Points remain on your record for five years from the date of the violation.
Options if you want to contest the ticket
You have the right to contest a speeding ticket in court. You can request a trial and present your case to a judge. Common defenses include challenging the accuracy of the speed measurement device, questioning whether the officer properly calibrated the radar or laser gun, or disputing whether you were actually speeding. You can represent yourself or hire an attorney.
Before going to trial, you can also request traffic school or a plea agreement. Some Illinois courts offer traffic safety courses that, if completed, result in the ticket being dismissed or reduced. This option is usually available only once every five years. Ask the courthouse about traffic school may be able to access when you contact them about your ticket.
Frequently Asked Questions
Can I pay my speeding ticket online?
Most Illinois counties allow online payment through their court website. Search for "[your county] Illinois traffic court" to find the payment portal. You will need your ticket number, which is printed on the ticket itself. If online payment is not available for your county, you can pay by mail or in person at the courthouse.
Does a speeding ticket in Illinois affect my out-of-state license?
Yes. Illinois reports violations to your home state through the Interstate Compact, a system that shares driving records between states. Your home state will add the violation to your record and may suspend your license or raise your insurance rates based on the Illinois conviction.
What is the difference between a speeding ticket and a speeding warning?
A warning is issued at the officer's discretion and does not result in a fine or court appearance. It is not reported to your insurance company or added to your driving record. A ticket is a formal citation that requires payment or a court appearance and is reported to your record.
Can I get a speeding ticket dismissed if I take a defensive driving course?
Some Illinois courts offer traffic safety courses that can result in dismissal or reduction of the ticket, but this is not automatic. You must request this option from the court and meet the court's requirements, which may include a clean driving record or first-time violation status. Contact your courthouse to ask whether this option is available for your ticket.
What happens if I ignore my speeding ticket?
Ignoring a ticket leads to a failure-to-pay penalty, license suspension, and a possible warrant for your arrest. The court can also refer the debt to a collection agency. It is better to contact the court and arrange a payment plan than to ignore the ticket.
