The City of Thornton and the Thornton Police Department are working to improve community safety by installing state-of-the-art digital red-light safety cameras and mobile speed cameras to decrease traffic violations and collisions and to help increase safety in our community.
Thornton has partnered with Verra Mobility to install red-light safety cameras at two intersections:
East 88th Avenue and Washington Street
Citations began Jan. 11, 2026
East 120th Avenue and Colorado Boulevard
Warning period start date Feb. 6, 2026
To reduce excessive speeding, Thornton will also place mobile speed cameras at various high-risk locations in the city.
Citations began Dec. 25, 2025
These cameras have been proven effective in reducing crashes and serious injuries. We want to stop this behavior before it becomes even more dangerous, or even fatal.
Verra Mobility’s programs across the U.S. gathered 4.6 million red-light citations in 2023, with a recidivism rate of 84%, meaning most violators did not repeat their illegal behavior. Speed programs issued 11.6 million speed citations with a 62% recidivism rate.
This is just one of the many tools Thornton is employing to keep the community safe.
Frequently Asked Questions
Red-light cameras have been proven to be effective in reducing red-light violations and right-angle collisions, and speed cameras consistently lessen reckless speeding and reduce pedestrian-related accidents. Municipalities using these systems consistently report safer roads with fewer collisions.
A Notice of Violation for a red-light violation is issued when a vehicle fails to stop at a clearly marked stop line or at any other stopping point described in the ordinance when facing a steady circular red signal, or if the vehicle does not come to a complete stop before making a right turn. Similarly, a Notice of Violation is issued when a vehicle fails to comply with the posted speed limit.
The fine for a red-light violation is $75. Failure to respond to a Notice of Violation, failure to appear for a requested hearing, or failure to pay a penalty imposed after a hearing may result in the issuance of a Summons and Complaint with personal service at an additional charge of $18. Once personal service has been provided, your appearance in court will be required.
Drivers will incur fines of $40 in a non-school zone and $80 in a school zone for speed violations.

The registered owner of a vehicle will be mailed the Notice of Violation. If your vehicle was stolen, sold before the date and time of the violation, the operator received a citation for this violation from a law enforcement officer, driver at time of the violation is deceased, or the vehicle was otherwise not in your care, custody, or control at the time of the violation, you may submit a sworn statement to that effect to rebut the presumption that you were driving the vehicle at the time of the violation.
Send the notarized Affidavit of Non-Responsibility (along with all supporting documentation and a copy of your Notice of Violation) back before the Due Date on the front of this Notice. Please mail to Violation Processing Center, PO Box 22091, Tempe, AZ 85285-2091, or email to Info@ViolationInfo.com, or fax to 1-480-990- 4819. If an Owner furnishes satisfactory evidence pursuant to this paragraph, the Court may terminate the prosecution of this Notice of Violation issued to the owner, and if appropriate, issue a Notice of Violation to the person identified in the evidence as the operator of the motor vehicle at the time of the violation. You will be notified of the outcome by mail. Keep in mind that submitting the Affidavit will NOT automatically result in the closure of this matter. If further information is required, you will be notified.

The red-light cameras capture violations for failing to come to a complete stop at a red light. Drivers who stop properly before turning right and proceed only when it is safe will not receive violations. Right turns on red are allowed as long as you stop first.
Thornton PD staff can only issue warnings or citations when a readable license plate is captured. Officers still conduct daily traffic enforcement and address violations like missing plates, expired registration, fake tags, or obstructed plates during those stops.
The system captures an image of any potential violation so it can be reviewed by Thornton PD staff. A warning or citation is only issued if the violation is confirmed. Drivers are notified by mail only when a confirmed violation occurs.
Officers continue regular traffic enforcement, including traffic stops, speed enforcement, and responding to crashes. The photo enforcement program is an additional tool to monitor high-risk intersections and locations prone to serious crashes.
No. These red-light and mobile speed cameras are part of Thornton PD’s photo enforcement program, used only to detect red-light violations and speeding. They capture a violation and the vehicle’s license plate, which is reviewed by staff before issuing a warning or citation.
The city does use Flock cameras, but those are license plate readers used for criminal investigations, such as locating stolen vehicles, missing persons, or suspects. Flock cameras are not used for traffic enforcement.
These cameras do not do any type of facial scanning. Images are reviewed by Thornton PD staff only to confirm the violation and issue a warning or citation to the vehicle’s registered owner. The system is strictly for enforcing red-light and speed violations.
Any funds generated go toward covering the cost of the camera program. The goal is for drivers to obey traffic laws, so ideally no violations will be issued. Any collected funds go to the general fund to offset program costs.
No. Yellow light timing is set by engineering standards and is not changed for photo enforcement. The cameras only record violations based on existing traffic signals and laws.
Yes. Photo enforcement signs are posted at locations with cameras in accordance with state law.
All drivers, including municipal vehicles, are subject to the same traffic laws. Drivers performing official duties and actively responding to an emergency are exempt. Otherwise, city employees driving city vehicles can receive violations just like any other driver.

How do mobile speed cameras work?
Step 1: The system activates when a vehicle is detected traveling in excess of the posted speed limit. Step 2: The system takes an image of the front of the vehicle to identify the driver. Step 3: The system takes an image of the rear of the vehicle to identify the license plate. Step 4: Additional data collected includes the time, date, posted speed, vehicle speed, location, lane and direction of travel. Step 5: The police review the images and data captured by the system to determine whether to issue a violation notice.
