Statewide

  1. May 23, 2025 Gov. Jared Polis signed SB25-276. It extends existing limits on disclosing personal identifying information for federal immigration enforcement from state agencies to counties, cities and other local governments, with civil penalties for intentional violations. The bill text summary does not mention plate readers specifically. Local officials, such as Longmont's police chief, have cited Colorado's bar on sharing personal information for immigration enforcement in discussing plate-reader data. (Complete Colorado, June 9, 2025; ACLU of Colorado, date not shown; Colorado General Assembly, date not shown; Boulder Reporting Lab, Dec. 11, 2025)
  2. 2026 Colorado law currently lets government agencies keep plate-reader data for as long as three years, according to SB26-070 sponsor Sen. Lynda Zamora Wilson (via Colorado Newsline) and CBS Colorado. Flock's default retention is 30 days, CBS Colorado reported. (Colorado Newsline, April 29, 2026; CBS Colorado, Sept. 22, 2025)
  3. Feb. 2026 The Senate Judiciary Committee advanced SB26-070 on a 5-2 vote, with Sens. John Carson and Dylan Roberts opposed. Colorado Newsline reported the vote as taking place on a Monday; its story is dated Feb. 24, 2026. The bill would have required a warrant for plate-reader database searches once three days had passed since a crime, blocked most sharing with out-of-state agencies, prohibited sale of historical data, required audits of who accesses the data, and limited retention to 30 days unless an active investigation needed more. Sponsor: Sen. Lynda Zamora Wilson; co-sponsors Sen. Judy Amabile and Reps. Yara Zokaie and Kenny Nguyen. (Colorado Newsline, Feb. 24, 2026)
  4. April 2026 SB26-070 died on the Senate floor when, at its sponsors' request, it was laid over until July 4, after the session's end. Colorado Newsline reported the day as a Wednesday in a story dated April 29, 2026. Sen. Judy Amabile told Colorado Newsline that Gov. Polis had threatened to veto the bill if it kept the warrant requirement; the governor's office did not immediately respond to the outlet. Police, sheriffs, district attorneys and cities opposed the bill, Colorado Public Radio reported. (Colorado Newsline, April 29, 2026; Colorado Public Radio, April 30, 2026)
