St. Louis red light cameras are back on the street as of 2024, and a violation costs you $100. The ticket is a civil municipal matter, no points land on your Missouri driving record, and the registered owner receives a notice by mail with a deadline to pay or contest. Ignoring that deadline is the one move that turns a routine fine into a bigger legal problem.
What the Ticket Costs and Whether It Hits Your Record
The fine is $100 per violation.1Violation Info. St. Louis, MO – Violation Info It’s handled as a civil municipal citation, not a criminal charge, so jail isn’t on the table.
Camera-generated violations are treated as non-moving violations in St. Louis. No points get added to your Missouri driving record. Without points, your insurer generally has no trigger to raise your rates. The program is built around collecting fines to deter red-light running rather than building a record that follows you to the Department of Revenue.
What Arrives in the Mail
If a camera catches the vehicle running a red light, the registered owner gets a mailed notice. Open it carefully, because everything you need to decide what to do is on it:
- High-resolution images of the vehicle, the license plate, and the driver.
- A unique ID number and PIN code to view the recorded video clip on a secure web portal.
- The intersection, date, time, and how long the signal had been red before the vehicle entered.
- The payment deadline printed on the notice.
- Instructions for paying or contesting.
Pull up the video before you do anything else. It shows exactly how long the light was red and where the vehicle was when it crossed the line. Vehicles already in the intersection when the signal changes don’t trigger a violation; the system only fires on vehicles that enter after the light is red. If you’re on the fence about contesting, the video is where you make the call.
How to Pay
Three ways to pay the fine:
- Online, through the city’s violation portal with a credit or debit card.
- By mail, with a check or money order sent to the St. Louis Municipal Court in the return envelope included with the notice.
- In person, at the St. Louis Municipal Courthouse clerk’s window during business hours.
Once the payment processes, the citation is resolved. Nothing more is required.
How to Contest a Citation
If you believe the ticket is wrong, do not pay it. Paying resolves the matter and functions as an admission. You have two routes.1Violation Info. St. Louis, MO – Violation Info
The first is a written dispute. Send your supporting documents along with the coupon printed on the back of the notice, using the provided envelope. A prosecutor reviews the materials and notifies you in writing. This path works best when the evidence speaks for itself: proof the vehicle was stolen, records showing you sold it before the violation date, or similar documents that don’t need testimony to explain.
The second is a court hearing. Contact the municipal court to request a date, then appear before a judge and present your case. If someone else was driving, this is where that gets sorted out. The current program captures the driver’s face along with the plate, so the driver photo on your notice can actually help you here. If the person in the image clearly isn’t you, that’s strong evidence.
Whichever route you choose, your written response or court request has to be in before the deadline on the notice.
What Happens If You Ignore It
Don’t ignore the notice. If you miss the deadline, the city issues a delinquent notice, and you may be charged with an additional offense on top of the original violation.1Violation Info.

Why the Cameras Came Back and How That Affects You
St. Louis ran red light cameras under an older ordinance until the Missouri Supreme Court struck that law down in 2015 in Tupper v. City of St. Louis. The court’s objection was specific: the old ordinance presumed the registered owner was the driver and put the burden on the owner to prove otherwise, which the court held unconstitutional because it relieved the prosecution of proving a core element of the violation.2vLex United States. Tupper v City of St. Louis The cameras went dark.
The restart came through Board Bill 105, which became Ordinance 71821 and took effect May 16, 2024. It repealed the old ordinance and created the Automated Camera Enforcement Act.3City of St. Louis. Board Bill Number 105 In Session 2023-2024 The key change for drivers: the new cameras capture both the plate and the driver’s face, and the city uses facial recognition and database matching to identify the actual driver before issuing a summons.4City of St. Louis. Automated Camera Enforcement Moves Closer to St. Louis Comeback The cameras are being placed at intersections with the highest rates of traffic-related injuries and fatalities in the city.
That identification step is what makes a wrong-driver defense practical now. The notice itself should show the face of whoever was behind the wheel, and that image is reviewable through the portal before you decide how to respond.
