Illinois Traffic Court Costs and Administrative Fees

Illinois traffic court costs start at $164 for the simplest minor offense resolved by written plea, rise to $226 if the same minor offense goes through a court hearing, and reach $325 for major traffic offenses. Those numbers are the court assessment only. The fine the judge imposes for the violation itself is a separate charge added on top, so the final bill for a ticket is almost always higher than the assessment number alone.

The Three Assessment Schedules

Illinois sets court costs through the Criminal and Traffic Assessment Act (705 ILCS 135), which assigns every traffic offense to a numbered schedule with a fixed total.1Justia. Illinois Compiled Statutes 705 ILCS 135 – Criminal and Traffic Assessment Act Three schedules cover the vast majority of traffic cases.

Fines are separate. A driver convicted of a major traffic offense owes the $325 assessment plus whatever fine the court sets for that particular violation.

Written Plea or Court Appearance

Not every ticket requires a trip to the courthouse. Under Illinois Supreme Court Rule 529, most minor traffic offenses can be resolved by mailing in a written guilty plea with the $164 Schedule 12 assessment.4Illinois Courts. Rule 529 – Written Pleas of Guilty in Minor Traffic Offenses It is the cheapest and simplest way to close out a minor ticket.

The trade-off is that a written plea is a guilty plea. A conviction goes on your driving record, and your insurance carrier will see it. If you want a shot at court supervision instead (more on that below), you need to appear in court or hire an attorney to appear for you. Appearing bumps the assessment from $164 to the $226 Schedule 10 amount, plus any fine the judge imposes. For many first-time drivers the extra $62 and the time spent are worth it to pursue a result that keeps the ticket off their public record.

Your citation will tell you whether an appearance is required and will list the date, time, and courthouse location. More serious offenses, including all misdemeanors, require a mandatory court appearance regardless of what you would prefer.

School Zone, Construction Zone, and Aggravated Speeding

Certain offenses carry statutory minimum fines that stack on top of the assessment, and these are the ones that catch drivers off guard.

Speeding in a school zone under 625 ILCS 5/11-605 carries a minimum fine of $150 for a first offense and $300 for a second, plus community service at the court’s discretion.5Illinois General Assembly. Illinois Compiled Statutes 625 ILCS 5/11-605 A first-time school zone ticket resolved by written plea runs at least $314 ($164 assessment plus $150 fine). Taking it to court pushes the minimum to roughly $376.

Construction zone speeding under 625 ILCS 5/11-605.1 is steeper: a $250 minimum fine for a first offense and $750 for a second. Both school zone and construction zone speeding have aggravated tiers. Driving 26 to 34 mph over the posted limit in either zone is a Class B misdemeanor, and 35 mph or more over is a Class A misdemeanor.6Illinois General Assembly. Illinois Compiled Statutes 625 ILCS 5/11-605.1 At that point the Schedule 9 assessment of $325 applies on top of the criminal penalties.

You do not need to be in a school or construction zone to face criminal charges for speeding. Under 625 ILCS 5/11-601.5, driving 26 to 34 mph over any posted limit on any Illinois highway is a Class B misdemeanor, and 35 mph or more over is a Class A misdemeanor.7Illinois General Assembly. Illinois Compiled Statutes 625 ILCS 5/11-601.5 A Class A misdemeanor can carry up to 364 days in jail. Because these are major traffic offenses, the $325 Schedule 9 assessment applies rather than one of the lower schedules. Doing 81 in a 55 does not feel criminal, but it crosses the 26 mph threshold and triggers misdemeanor charges with a court cost bill to match.

Court Supervision and What It Costs

For most traffic offenses punishable only by a fine, an Illinois judge can grant court supervision instead of entering a conviction. If you complete the supervision period (typically four months) without a new violation, the case is dismissed and nothing goes on your public driving record.8Circuit Court of Cook County. Court Supervision The clerk still reports the supervision to the Secretary of State, but that record is confidential and cannot be shared with insurance companies.

Supervision usually comes with conditions. The judge will typically require payment of a fine, attendance at traffic safety school, or both. Traffic safety school fees run roughly $49 to $85 depending on the provider and format, and those fees are separate from the court assessment. If you fail to complete any requirement, the court can convert your supervision into a conviction and add more fines and costs.

Supervision is not available for every offense. You cannot get supervision for speeding in a construction or school zone, passing a school bus that is loading children, or a second offense of driving without insurance, among other exclusions.8Circuit Court of Cook County. Court Supervision Where it is available, the long-term insurance savings from keeping a clean record usually outweigh the added traffic school cost.

Finding Your Balance and Paying

Your citation is the starting point. The ticket number, usually printed in a corner, is the key identifier in every court database. You also need the county that issued the citation, since each county’s Circuit Clerk maintains its own records.

Most Circuit Clerk offices have an online portal where you can enter your case number or name and pull up an itemized balance: the base fine, the assessment schedule amount, and any additional charges. Online payment by credit or debit card is typical, with a convenience fee of roughly 2% to 3% from the third-party processor. The percentage varies by county, so check the total before confirming.

If you pay by mail, most clerk offices accept money orders and cashier’s checks but not personal checks. In-person payment at the courthouse gives you an immediate receipt, which is worth having as proof of compliance. Whichever method you use, payment must be received by the deadline on your citation or the date set during your court appearance.

Missing Court or Falling Behind on Payment

Missing a court date escalates quickly. For a petty traffic violation, the court will typically enter a conviction in your absence, and the clerk notifies the Secretary of State, who will suspend your driving privileges until you resolve the ticket. For misdemeanor traffic charges, the court will generally issue a bench warrant for your arrest instead of, or in addition to, entering a judgment.

If fewer than 30 days have passed since the missed date, most courts will reopen the case on request. Beyond 30 days you are past the appeal window and reopening becomes significantly harder. Even if you cannot pay the full amount, showing up and asking for a payment plan is far better than skipping the date.

Non-payment is treated differently from non-appearance. Under the License to Work Act, which took effect July 1, 2020, the Secretary of State can no longer suspend, cancel, or refuse to renew a driver’s license solely because of unpaid traffic fines or penalties.9Illinois General Assembly. Illinois Compiled Statutes 625 ILCS 5/6-306.6 (Repealed) As of July 1, 2021, the Secretary of State was required to reverse any existing suspensions imposed for non-payment. That protection does not erase the debt. Unpaid court costs can be sent to collections, and the court still has authority to enforce the judgment through other means. It also does not cover failure to appear, which remains a license-suspension trigger. If you cannot afford the full amount, call the clerk’s office about a payment plan and stay engaged with the court.
