Are Flock Cameras Legal in Colorado? Yes — and largely unregulated. Flock’s license plate readers are lawful to operate in every state; the real question — the one this page answers — is what rules Colorado puts on them: how long your plate data can be kept, who can search it, whether a warrant is needed, and what rights you have to see the record.
Here is the fact that surprises most drivers: Colorado has no ALPR-specific statute at all, which means the rules are set by Flock defaults and each local contract — and that gap is exactly what the current legislative fights are about. All details are for general guidance, verified against Colorado sources as of September 2026.
In This Colorado Guide:
Are Flock Cameras Legal in Colorado? The Short Answer
NONE — Colorado has no ALPR-specific statute. Local policy and general surveillance law govern. The only statute that touches ALPR-style data is the generic passive-surveillance records law, C.R.S. 24-72-113 (enacted 2008, amended since), which was not written for license plate readers. Colorado is one of roughly half the states with no dedicated ALPR statute; two 2026 bills that would have created one (SB26-070 and SB26-071) both died. Source: Colorado Division of Criminal Justice, Office of Research and Statistics, “In Detail: Automated License Plate Readers” (https://cdpsdocs.state.co.us/ors/Docs/Briefs/2024-05_InDetail-ALPR.pdf).
With no state law, Colorado is governed city by city, and the range is wide. Boulder PD operates 31 Flock cameras under a policy with a 30-day retention setting, no immigration or traffic-only-hit use, and national lookup disabled for out-of-state agencies. Denver ran 111 solar cameras at about 70 locations before ending the program. Clear Creek County and Glenwood Springs publish public Flock FAQ pages. Colorado Springs moved in February 2026 to nearly triple its reader network.
Lafayette, like Boulder, chose to keep 30-day retention after Flock moved its default to seven days. Fort Collins and Salida went the other way and cancelled outright. Several city councils have voted on Flock contracts as budget items, which is the practical control point — Denver council rejected a 666000 two-year extension on May 5, 2025, and the administration then signed a 498500 extension, 1500 below the threshold that would have required a council vote.
What Colorado Law Actually Requires
| Question | Rule in Colorado |
|---|---|
| ALPR statute | NONE — Colorado has no ALPR-specific statute. Local policy and general surveillance law govern. The only statute that touches ALPR-style data is the generic passive-surveillance records law, C.R.S. 24-72-113 (enacted 2008, amended since), which was not written for license plate readers. Colorado is one of roughly half the states with no dedicated ALPR statute; two 2026 bills that would have created one (SB26-070 and SB26-071) both died. Source: Colorado Division of Criminal Justice, Office of Research and Statistics, “In Detail: Automated License Plate Readers” (https://cdpsdocs.state.co.us/ors/Docs/Briefs/2024-05_InDetail-ALPR.pdf). |
| Data retention | NONE specific to ALPR. C.R.S. 24-72-113 caps “passive surveillance records” held by a government entity at three years from creation, and requires the custodian to log the reason for access and the person accessing any such record kept beyond one year. That is a ceiling, not an ALPR rule, and it is far longer than Flock’s contractual default. Flock’s own default was 30 days in Colorado deployments; the company announced in August 2026 it is cutting the platform default to seven days. Boulder and Lafayette have said they will keep a 30-day retention setting rather than move to the shorter default. Colorado law itself does not require any specific ALPR deletion period. |
| Who can search | No state-law standard. Colorado does not require a warrant, probable cause, or reasonable suspicion to run an ALPR/Flock search. Access is set by each agency’s own general order and its Flock contract — typically sworn officers and civilian analysts running plate or vehicle-description queries for a stated law-enforcement purpose. SB26-070 would have required a warrant to search historical location databases more than 72 hours after the crime under investigation, with emergency exceptions; it failed on April 29, 2026. Until a court or the legislature says otherwise, whether a warrantless Flock search violates Article II, Section 7 of the Colorado Constitution is an open question now being litigated in Boulder. |
| Immigration use | YES — but through general immigration-data law, not an ALPR statute. Senate Bill 25-276, effective May 2025, bars any Colorado state or local government entity from sharing personal identifying information — license plate data included — for the purpose of federal immigration enforcement, and tightens earlier limits in HB19-1124 and SB21-131. Local layers on top: Denver Mayor Mike Johnston signed an executive order in February 2025 barring ICE access to city databases and technology absent a subpoena, warrant, or court order; Boulder stopped sharing ALPR data on the national Flock network in June 2025 and blocks non-Colorado agencies from national lookups; Boulder PD policy bars use for immigration enforcement, for traffic enforcement based solely on a camera hit, and for any non-law-enforcement purpose. Enforcement has been the weak point — Colorado Newsline reported on August 6, 2025 that Denver Flock data had been searched for immigration-related reasons, and Denver PD audit logs released to council on July 23, 2025 showed Denver data searched more than 1,400 times in connection with ICE since June 2024. 9NEWS reported that Loveland police had shared ALPR access with Border Patrol. |
| Data sharing | No general state restriction. Colorado agencies may share ALPR data with out-of-state and federal agencies except where SB25-276 blocks immigration-purpose sharing, or where a local policy or contract setting blocks it. Flock’s national lookup feature is on or off at each agency’s election — Boulder turned off out-of-state access; other Colorado agencies have left national sharing enabled. SB26-070 would have banned most out-of-state sharing and banned sale of historical data; it died. |
| Search audits | NONE required by Colorado law for ALPR specifically. C.R.S. 24-72-113 requires an access log only for passive surveillance records retained past one year, which does not reach 30-day ALPR data. In practice, audit logs exist because Flock generates them — that is how Denver’s ICE-related search counts surfaced, after Denver PD and the mayor’s office withheld the logs for more than three months before releasing redacted versions on July 23, 2025. SB26-071 (the SAFE Act) would have required an attorney general audit of law enforcement every two years and given the AG civil enforcement authority; Senate Judiciary postponed it indefinitely on May 6, 2026 on the sponsor’s own motion. Flock announced in August 2026 that misuse-detection auditing, “Audit Assistance” anomaly flagging, proactive lockout, and case-number-linked searches become mandatory for law enforcement customers by January 1, 2027 — a vendor policy, not Colorado law. |
The retention number is the one to watch. Flock’s national default is 30 days; some states now force shorter windows by statute, and where Colorado law is silent, the local contract decides. When people ask “are flock cameras legal in Colorado,” the retention and search rules above are usually what they actually need to know.
Misuse penalties: NONE ALPR-specific. Colorado has no statutory criminal or civil penalty aimed at ALPR misuse by police or civilians. Misuse would have to be charged or sued under general law — official misconduct, computer crime, POST decertification proceedings, an internal affairs action, or a state constitutional claim like the one pending in Boulder. SB26-071 would have created AG civil enforcement; it died May 6, 2026. SB25-276 restricts immigration-purpose data sharing but is not a criminal penalty statute.
Your Rights: Seeing What Colorado Has on Your Plate
Knowing whether are flock cameras legal in Colorado is only half the question — the other half is what you can see about your own plate. Two routes, both discretionary. Law enforcement ALPR records are criminal justice records, so the request goes under the Colorado Criminal Justice Records Act (CCJRA), C.R.S.
24-72-301 et seq., to the records custodian of the agency that operates the cameras — for example the Boulder Police Department Records Unit or the Denver Police Department Records Section. Records held by a non-law-enforcement agency (a city transportation department, CDOT) go under the Colorado Open Records Act (CORA), C.R.S.
24-72-201 et seq. Critical caveat: CCJRA release is discretionary, not mandatory. In the Boulder case, resident William Freeman used CCJRA to ask for all images and metadata of his own vehicle for the full retention period, and Boulder PD’s records supervisor refused, saying a search would violate department policy and its Flock contract because the system may only be accessed for documented criminal investigations.
Freeman’s position is that Harris v. Denver Post Corp. (Colo. 2005) requires a custodian to weigh privacy and public interest before denying. That dispute is unresolved. If a custodian denies, C.R.S. 24-72-305(7) lets you apply to the district court in the county where the records are held to show the denial was arbitrary or capricious.
Many Colorado drivers can file the request; you may or may not get the images, and you should expect a denial citing the vendor contract. Check with the specific agency and, if it matters to your case, with a Colorado attorney.
A records request is the single most useful lawful move for a driver asking are flock cameras legal in Colorado: it is free or cheap, it forces the agency to state its rules on paper, and the answers feed every other channel — council testimony, comments on pending bills, or a lawyer if the logs show misuse. If a camera-based citation is the concern, the Flock camera ticket guide for Colorado covers that side.

The Backlash in Colorado: Cancellations, Lawsuits & Cases
• May 5, 2025 — Denver City Council unanimously rejected a 666000, 24-month Flock extension covering 111 cameras. The administration signed a 498500 extension on October 22, 2025 instead, just under the council-approval threshold, drawing a formal council rebuke on October 29, 2025. Denver ended its Flock contract on February 24, 2026 (Colorado Politics). • June 2025 — Boulder stopped sharing ALPR data on the national Flock network accessible to ICE (Boulder Reporting Lab, August 19, 2025). • July 23, 2025 — Denver PD released redacted Flock audit logs to city council after a delay of more than three months; the logs showed Denver data searched more than 1,400 times in connection with immigration enforcement since June 2024 (Colorado Newsline, August 6, 2025; Denverite, July 1, 2025). • November 2025 — ACLU of Colorado called for a statewide moratorium on ALPR systems until meaningful safeguards exist, and separately demanded an end to Flock contracts over ICE surveillance.
What Flock and Other Vendors Are Saying
• August 2025 — In response to the Denver audit-log reporting, Flock and Denver officials defended the program on crime-solving grounds while the city moved to restrict ICE-related access; Denver’s mayor’s office cited data-security fixes. • October 22, 2025 — Denver’s administration extended the Flock contract citing public-safety value, over council objection.

Colorado FAQ: Are Flock Cameras Legal in Colorado
Can I find out if police searched my plate in Colorado?
Often, yes. ALPR search logs are records, and public-records laws reach many of them — the request path in the rights section above is the route. Some state statutes require agencies to keep audit logs precisely so this question is answerable. Expect exemptions for active investigations, but the policy, the retention schedule, and aggregate search data are routinely producible.
Do Flock cameras use facial recognition?
No — the cameras photograph vehicles and plates, not faces, and the company states the system does not identify drivers or passengers. The privacy concern is different and real: a network of timestamped plate captures builds a movement history of your vehicle, which is why retention limits and search rules are where every serious legal fight is happening.
Is it illegal to block or damage a Flock camera in Colorado?
Damaging one is criminal property destruction — and prosecutions are real: vandalism cases around the country in 2026 have drawn felony charges, including over a police decoy camera. Blocking or obscuring one on public land can also draw obstruction or tampering charges depending on state law. The lawful channels — records requests, council testimony, pending bills — are covered above, and they are the ones actually cancelling contracts.
Why the Answer to “Are Flock Cameras Legal in Colorado?” Keeps Changing
ALPR law is the rare corner of traffic law being written in real time. The cameras spread faster than legislatures could react, so the first rules were whatever the vendor’s defaults and each city’s contract said. Now the statutes are arriving — retention caps, search standards, immigration-use bans, audit duties — and every session moves the line somewhere. A page that answered “are flock cameras legal in Colorado” correctly last year can be wrong this year.
The fights driving it are concrete: officers caught running personal searches, federal agencies reaching into local data, cities discovering their contracts allowed sharing they never intended. Each scandal produces a bill; each bill resets the rules. That is why the dated sections on this page exist and get refreshed — the statute table is the stable part, and everything else is a moving front.
For a driver, the takeaway is to check the date on anything you read about are flock cameras legal in Colorado — including this page, which is why its verification date is printed above — and to anchor on the statute citations, which are the one part of this fight that is always checkable at the source.
