ALPR Laws in Montana

What Montana's license plate reader rules look like — and the records law you can use to ask your city.

Verified Aug 18, 2026
Your records law: Montana's public records requests run under the Montana Public Records Law. That's the law to cite when you ask your city about its ALPR program.

What's reported in Montana

Montana-specific ALPR rules are being compiled from public records — no verified statewide summary yet.

As in most states, ALPR deployment and data rules are set partly by state law and partly by local policy — retention periods, access limits and sharing agreements vary city by city. The definitive answer for your city comes from its records, not from a national summary.

Ask for the actual policy

Use the FOIA generator to write a state-specific request under the Montana Public Records Law — asking for the ALPR contract, camera locations, retention policy and data-sharing agreements. It takes about 2 minutes.

How to file a records request in Montana

Filing under the records law is a repeatable process. In order:

  1. Identify the right agency — state police, county sheriff, or city police. The agency that operates the cameras holds the records.
  2. Generate the request — use our FOIA generator to produce a state-specific letter covering the contract, camera locations, retention policy and data sharing.
  3. Send it to the records division — find the email on the agency's website under "Records" or "Public Information." Keep a copy with the date sent.
  4. Wait the statutory period — most states require a response within 10–30 days. Mark the deadline on your calendar.
  5. Follow up if needed — no response by the deadline? Send a brief follow-up citing the law and the original date. Persistence is normal and expected.

Common exemptions & appeals

Records laws aren't absolute — agencies may withhold records under exemptions such as active investigations, certain law-enforcement techniques, or information protected by other statutes. If part of your request is denied, the agency must typically cite the specific exemption and identify what's withheld. You generally have the right to appeal the denial administratively, and ultimately to seek review in court. An attorney or a local open-records advocate can help with appeals.

What to do with the answers

  • Compare the retention policy against what's reported about plate data retention.
  • Check whether cameras were approved in a public meeting — council minutes are public.
  • Bring the facts to a city council or HOA meeting, or share them via the ban tracker precedent.
