This is the Rule 529 pre-court guilty-plea option, not every judge’s fine or a school/work-zone charge. At 26–34 mph over, speeding is a Class B misdemeanor; at 35+ it is Class A. Those criminal charges require court and are not priced here.

The statutory fine and the payable amount.
Schedule 12 of the Criminal and Traffic Assessment Act sets the $164 assessment used for an eligible written guilty plea under Supreme Court Rule 529. The rule prohibits ordinary additional fines or costs in this narrow disposition. Illinois Vehicle Code 11-601.5 classifies 26-34 mph over as Class B aggravated speeding and 35+ as Class A; those charges are excluded from this payment schedule. School and work-zone charges also require their separate disposition.

Compare the neighboring speed bands.
Your record is a separate cost.
Illinois assigns 5, 15, 20 or 50 points by the ordinary-speed band. School/work-zone offenses have a different schedule, including55 for aggravated zone speeding. Points help determine licensing action; adult review also depends on conviction count.
For a standard adult license, the Secretary of State may suspend or revoke after at least 3 moving-violation offenses committed within 12 months. Young-driver and serious-offense rules differ. A single point threshold would misstate this conviction-based trigger.
Ordinary moving-violation convictions remain on the driving record4–5 years from conviction. If they support suspension or revocation, the record remains for at least 7 years after reinstatement. Record retention differs from the12-month conviction window.

The 2026 ValuePenguin quote study reports a 24% average increase for one speeding ticket in Illinois. Your insurer, coverage and driving history can produce a different result. Read the study and its sample.
The NAIC 2023 combined average premium for Illinois is $1,256.58 per year. This historical measure combines liability, collision and comprehensive averages.
At $1,256.58 per year and 24%, the illustration adds $301.58 per year, about $25.13 per month.
Applying a 2026 quote-study percentage to the historical 2023 NAIC combined premium is illustrative math. These sources use different populations and coverage methods; this is not a measured post-ticket average or a current quote. No future premium increase is included in a court fine.

How much is 15 over in Illinois?
The estimate shown is $164. This is the Rule 529 pre-court guilty-plea option, not every judge’s fine or a school/work-zone charge. At 26–34 mph over, speeding is a Class B misdemeanor; at 35+ it is Class A. Those criminal charges require court and are not priced here.
Will my insurance go up?
A conviction can affect premiums, but your insurer uses its own rules. The 2026 ValuePenguin quote study reports a 24% average increase for one speeding ticket in Illinois. Your insurer, coverage and driving history can produce a different result. A points-free outcome does not promise an unchanged premium.
Does traffic school remove points?
A county may offer court supervision on a written plea for eligible minor offenses, sometimes with an approved traffic-safety program. Course fees are additional. Missing the certificate deadline can revoke supervision and enter a conviction; county eligibility and your history control. Confirm eligibility before enrolling or paying your ticket.
Is this the amount I should pay?
No. The estimate explains a published schedule. Pay only the amount confirmed by the court handling the citation, through its official instructions.
What if I do not respond on time?
Follow the response or appearance date on the citation. Rule 529 allows an eligible written guilty plea and payment before an appearance; missing both the response and appearance date moves the case into the Rule 556 procedure. Missing a deadline can add consequences. Ask the court about extensions or payment help before it passes.
