Yes, Iowa speed cameras are legal and operating, but the rules changed in 2024. Every camera location on a state road now needs a permit from the Iowa Department of Transportation, cameras can only ticket you for going more than 10 mph over the posted limit, and the citation is a civil penalty that does not affect your license or insurance.
The 10 MPH Rule and What You’ll Pay
A camera in Iowa cannot issue a citation unless you exceed the posted speed limit by more than 10 miles per hour.1Iowa Legislature. Iowa Code 321P.3 – Use Limited Nine over, nothing. Eleven over, you’re in range. The threshold is the same for every automated camera in the state, fixed or mobile.
State law caps the fines, which climb with the speed. Outside work zones:2Iowa Legislature. Iowa Code 321P.6 – Enforcement
- 11 to 20 mph over: up to $75
- 21 to 25 mph over: up to $100
- 26 to 30 mph over: up to $250
- More than 30 mph over: up to $500
In a work zone, every tier doubles:2Iowa Legislature. Iowa Code 321P.6 – Enforcement
- 11 to 20 mph over: up to $150
- 21 to 25 mph over: up to $200
- 26 to 30 mph over: up to $500
- More than 30 mph over: up to $1,000
These are ceilings. Some cities set their fines at or near the cap, but none can go higher.
What a Camera Ticket Is and Isn’t
A speed camera citation in Iowa is a civil infraction, not a criminal traffic violation. The DOT cannot use it in driver’s license decisions, and your insurance company cannot use it to adjust your rates.2Iowa Legislature. Iowa Code 321P.6 – Enforcement No points land on your license. That’s a real difference from a regular speeding ticket written by an officer at the roadside.
The tradeoff is who gets billed. The citation goes to the vehicle’s registered owner, not the driver. If someone else was behind the wheel, you can submit evidence that you were not driving, but you have to provide the name and address of the person who was.3Iowa Legislature. Iowa Code 321P.7 – Liability for Violations Detected If the city accepts the evidence, the citation can be amended and reissued to that driver.
Before any citation goes out, a peace officer or a certified reviewer has to look at the photograph or video and confirm a violation occurred. The system doesn’t mail tickets on its own.2Iowa Legislature. Iowa Code 321P.6 – Enforcement The images themselves are also limited by law: the camera can capture the rear of the vehicle and the license plate, nothing more. A citation from a camera that photographs the front of the car or anyone’s face is void.4Iowa Legislature. Iowa Code Chapter 321P – Automated Traffic Enforcement
Where Cameras Are Allowed to Operate
House File 2681, signed in 2024, created Chapter 321P of the Iowa Code and put the DOT in charge of approving every automated enforcement location on state roads.5Iowa Legislature. House File 2681 – Automated Traffic Systems A city has to show that the camera is “appropriate and necessary” and the “least restrictive means” of addressing a documented safety problem at the exact spot where it wants to use one.4Iowa Legislature. Iowa Code Chapter 321P – Automated Traffic Enforcement
The first statewide review wrapped up in late 2024. The DOT received 348 location applications, approved 154, and denied 194.6Iowa Department of Transportation. Iowa DOT Issues Rulings on Automated Traffic Enforcement in 348 Locations Across Iowa More than half the cameras cities wanted to keep running were shut down. The ones still operating, in places like Cedar Rapids, Des Moines, and Davenport, cleared the new standard or won on appeal.
City size also matters. Cities with 20,000 people or fewer cannot use mobile speed cameras at all. In larger cities, mobile units are limited to neighborhoods, construction zones, school and college campus zones, and locations where conventional enforcement would be difficult or dangerous.1Iowa Legislature. Iowa Code 321P.3 – Use Limited
Signs You Should Have Seen
Iowa doesn’t let cities operate cameras in secret. A fixed camera has to have a permanent warning sign posted between 500 and 1,000 feet before the camera on the approaching highway. A mobile camera requires permanent signs at every point where a road enters the city, letting drivers know mobile enforcement is used there. Either way, the signs must be in place for at least 30 days before any citations go out.4Iowa Legislature. Iowa Code Chapter 321P – Automated Traffic Enforcement
Signs also have to meet the DOT manual on uniform traffic control devices for size, reflectivity, and placement. A camera running without proper signage is out of compliance, and any citation it issues during that window is void.2Iowa Legislature. Iowa Code 321P.6 – Enforcement
How to Contest a Ticket
You can challenge a camera citation. The ticket itself includes instructions for requesting an administrative hearing, and some cities let you do it by mail rather than in person. The grounds that actually tend to carry weight are specific: you weren’t the driver and can name who was, the camera wasn’t properly calibrated, the required signage was missing or hadn’t been up for 30 days, or the system was otherwise out of compliance with Chapter 321P. The law says a citation from a non-compliant system is void.2Iowa Legislature. Iowa Code 321P.6 – Enforcement
Calibration is a real avenue. Every camera system has to verify its internal calibration daily, and a trained technician has to run an additional monthly calibration. The city keeps a log of every one, and if either check fails, the camera can’t operate until it passes. Those logs are admissible in court, so you can request them if you’re contesting a ticket.4Iowa Legislature. Iowa Code Chapter 321P – Automated Traffic Enforcement
If you request a hearing and lose, you’ll owe the original fine plus court costs and a filing fee, which runs roughly $95 to $100 depending on the city. Factor that in before deciding whether to fight a $75 ticket.
What Happens If You Ignore It
Not paying is a worse idea than most people think. The citation is civil, but cities have real collection tools. The pattern varies by city, but you typically have a 30- to 60-day window to pay. Miss it and late fees or collection activity start. Davenport adds a $25 late fee after 60 days. Cedar Rapids sends unpaid citations to a collection agency after 60 days and can file a civil court action within a year of the violation.
Some cities have gone further and used Iowa’s tax setoff program, which lets a government agency intercept your state tax refund to cover a debt. Cedar Rapids has done this with persistent non-payers. Legislation introduced in the 2025 session, House File 3, would prohibit using the setoff program for unpaid camera fines going forward, but unless and until it passes, your refund is on the table.
