Can You Get Traffic Light Camera Footage After a Collision?
The Short Answer
Sometimes, but often not. Footage from cameras at traffic lights can be obtained only if the camera actually recorded the moment of your collision and the recording still exists when you ask for it. Many cameras mounted near signals never record at all. They exist to detect waiting vehicles or to stream live traffic views. Where a recording does exist, you usually get it through a public records request, the police investigation, your insurer, or an attorney's preservation request or subpoena. Speed matters most, because stored video is commonly overwritten on a rolling basis.
Two conditions change the answer. The first is the type of camera and who operates it. The second is your jurisdiction, because records laws, exemptions, fees and retention practices differ by state, county and city across the US.
Which Cameras at an Intersection Actually Record
A camera on a signal pole is not necessarily a recording camera. Knowing what you are looking at tells you whether it is worth asking and whom to ask.
Camera type | Typical purpose | Does it usually keep video? | Who to ask; Signal detection camera | Senses vehicles waiting so the light can change | Usually no; it processes images to trigger the signal and typically does not store them | City or county traffic engineering department; Red-light enforcement camera | Captures vehicles entering on red to issue citations | Often only short clips or still images when a violation is triggered, not continuous video | The city or county running the program, which may contract a private vendor; State DOT traffic monitoring camera | Live views of road conditions for traffic management and traveler information | Frequently live-only; recording is not guaranteed and varies by agency | State department of transportation; City or police surveillance camera | Public safety monitoring | Often records, with retention set by local policy | Police department or city records office; Private business or home camera | Security for a store, gas station or residence | Often records, but owners may overwrite quickly | The property owner or manager
Red-light enforcement cameras deserve a closer note. Because they are designed to document violations, they may have captured your crash only if a vehicle triggered them at the right moment. Even then, they may store a few seconds or a set of stills rather than the full sequence of events.
About Colorado's Traffic Camera Network and Archives
People in Colorado often look for an archive of the state's traffic camera views after a crash. The Colorado Department of Transportation runs a large network of roadside cameras for its traveler information service. Like many state DOT systems, that network is built mainly for live viewing. Do not assume a publicly browsable archive of past footage exists. If you need to know whether a particular camera recorded a particular time, ask the department directly and promptly. Requests for public agency records in Colorado generally fall under the Colorado Open Records Act, often shortened to CORA. Cameras run by a city, county or police department are handled by that local agency, not the state.
How to Request the Footage Step by Step
1) Write down the exact location, date, time and direction of travel as soon as you safely can. Note which corners of the intersection have cameras and photograph them, including any visible labels or operator markings. 2) Identify the likely operator of each camera using the table above. Signal and enforcement cameras usually belong to the city or county. Highway cameras usually belong to the state DOT. Cameras on buildings belong to the property owner. 3) Contact the agency or owner quickly and ask two things: whether the camera records, and how long recordings are kept. Ask them to preserve footage for the relevant time window while your formal request is processed. 4) Submit a written public records request to the agency's records custodian. Use the federal Freedom of Information Act only for federal agencies; state and local agencies follow state open records laws. Include the location, camera position if known, date and a time range several minutes before and after the crash, and ask for the native video file rather than a screen recording. 5) Get the police report number and tell the investigating officer that cameras may have captured the collision. Investigators can sometimes obtain footage faster than private citizens. 6) Notify your insurance company and give it the same camera details. Insurers routinely request evidence for claims. 7) If injuries, serious damage or a liability dispute are involved, consider an attorney. A lawyer can send a formal preservation letter and, if a lawsuit is filed, use a subpoena to compel production. 8) Ask nearby businesses separately. Private owners are not bound by records laws, so a polite, prompt request is your main tool. Offer to have them save a copy to a USB drive or give them your insurer's or attorney's contact.
Why a Request Can Be Denied or Come Back Empty
The camera never recorded, which is common for detection and live-view cameras. The recording was overwritten before your request arrived. The agency withholds it under an exemption, for example because it is part of an active criminal investigation or contains other people's private information. The camera was pointed elsewhere, malfunctioning or obstructed at the time. Your request was too vague to locate the right file, or it went to the wrong agency. Fees for search, redaction or copying apply, and the request stalls until they are paid.
If you are denied, ask for the reason in writing and which exemption applies. Many state records laws provide an appeal or review process. A narrower or corrected request, or a request routed through police, an insurer or an attorney, may succeed where a first attempt did not.
Checking the Footage Once You Have It
Confirm the timestamp matches the crash time, keeping in mind that camera clocks can drift or be set to a different time zone. Confirm the view shows the correct intersection and the approach directions that matter to your case. Check that the clip covers the lead-up, the impact and the aftermath, including the signal phase if visible. Keep the original file unaltered and work only from copies. Record who provided it, when and in what format, along with any cover letter or certification, which helps establish authenticity later. Share copies with your insurer or attorney rather than posting the video publicly, which can complicate a claim.
Do Not Rely on Cameras Alone
Even when a traffic light camera is present, treat its footage as one possible piece of evidence. Photograph vehicle positions, damage, skid marks, debris and the signals themselves. Collect contact details from witnesses, and save any dashcam video from your own vehicle or others involved. If the official footage turns out not to exist, this other evidence may still establish what happened.
