Automated Photo Enforcement Program - Red Light Cameras

In late July 2006, the City of Seattle initiated a 12-month pilot project designed to test the effectiveness of traffic safety cameras – also known as red light cameras – at selected arterial intersections. The purpose of the project was to gauge the extent to which these cameras might reduce the frequency of red light running and associated accidents, events which have become all too frequent in recent years, not only in Seattle but throughout the country.

Altogether, six camera systems were deployed at four intersections in the pilot project. After 12 months, through July 23, 2007, 16,539 citations were issued. The Final Evaluation Report, summarizes the results of the pilot and evaluates the performance of the red light cameras and the City's red light camera vendor, American Traffic Solutions, Inc. (ATS) of Scottsdale, Arizona.

Based on the favorable findings of the pilot project, the City approved a significant expansion of the program in 2008, 2009, and 2013 involving the addition of 25 new cameras at intersections throughout Seattle. Four factors were weighed in choosing locations for the new cameras: right-angle crashes, serious pedestrian injuries, the frequency of red light running based on video observation, and geographic distribution.

With the completion of construction in September 2013, the City now has 31 "red light" traffic safety cameras operating at 23 different arterials intersections. 

How do the cameras work?

The Axsis RLC-300 camera system used by ATS has three basic components: a high resolution camera for taking still, color photos, a video camera that provides a broader view of the offending vehicle and any other vehicles, pedestrians, or cyclists in the intersection, and a vehicle sensing device that activates the still cameras and captures video of approaching vehicles that the system "predicts" will violate a red signal.

Red Ligth Camera

The stills show the vehicle behind the stop line with the traffic signal showing red in the image #1 photo and the same vehicle fully beyond the stop line with the traffic signal still showing red in image #2 photo. These two photos, together with a cropped image of the vehicle license plate are included in the citation (also known as the notice of infraction (NOI)) that is sent to the registered owner of the vehicle. The still photos and video clip of the event are available to police reviewers, court personnel, and registered owners via secure ATS Internet Web site. All photos and video only show the vehicle from the rear, as Washington law prohibits taking images of the faces of vehicle driver or occupants.

Photos and videos of violation events are sent electronically from the traffic safety camera system to the ATS data center where they are reviewed against criteria established by the Seattle Police Department. Events that clearly are not violations are rejected at the data center. Events that appear to be a violation are forwarded to trained officers in the SPD Traffic Section, who authorize issuance of citations for those deemed in violation, review events that appear to meet SPD criteria.

Use the coupon enclosed with your ticket to request a mitigation hearing or contested hearing. To submit a declaration of non-responsibility, follow the instructions on the ticket.

  • A HEARING TO EXPLAIN THE CIRCUMSTANCES: By requesting a mitigation hearing, you will be deemed to have committed the infraction. You may not subpoena witnesses for this hearing. You would request a mitigation hearing if you agree you committed the infraction but believe the circumstances may be such that the court could reduce or waive the penalty.
  • A HEARING TO CONTEST THE INFRACTION: At a contested hearing the City has the burden of proving by a preponderance of the evidence that the infraction was committed. You may subpoena witnesses including the officer who issued this Notice of Infraction. If you request a contested hearing the Court will schedule a pre-hearing conference, which you may waive by using the form attached to the Notice of Hearing that the Court will send you.
  • SUBMIT A DECLARATION OF NON-RESPONSIBILITY: If your vehicle was stolen, sold by you prior to the date of the violation, or 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 the Court to rebut the presumption, established in SMC 11.31.090, that you were driving the vehicle at the time of the violation.

A photo enforced violation is treated like a parking infraction. There are no issues with your license, no points assessed, and no impact to your insurance.




You may view the photographic images and video online at www.ViolationInfo.com. You must use the Notice # and PIN printed on the front of the notice to login.

Persons without access to a computer can visit any Seattle Public Library branch or at the Municipal Court (600 Fifth Avenue) to view photographic and video evidence.




If this occurred during school hours and the beacons were flashing, then you probably have a ticket, but keep in mind, in some cases the system is monitoring multiple lanes of traffic. If it occurred at any other time (e.g. nighttime and/or beacons off), then it's likely that the camera was conducting a self-diagnostic test and you will not have a ticket. In the event, controls are in place to avoid the issuing of erroneous citations outside of the enforcement period or during equipment malfunction.
