Plate Reader Audit Obligations: free sample (Tensorust LLC)

4,081 US agencies run plate readers; 648 sit in states with an audit or access-log law, and 32 Minnesota agencies have no audit in the state file.

Headline: Plate reader programs now carry state audit duties (Minnesota requires an independent audit every two years, Virginia an internal audit every 30 days, Washington a yearly audit from 2026), but no one tracks which agencies owe one.

This repository is a free teaser, not the dataset. It holds 25 example rows and a summary table with no names in it. The full file has 4,081 rows and is sold by Tensorust LLC: https://tensorust.com/datasets/alpr-audit-obligations/.

Method and limits

Take every Atlas record whose technology is Automated License Plate Readers, group by state and agency, and merge vendors and evidence dates. Attach the state statute where this table has one. For Minnesota agencies, match the agency name against the titles and entities of the LRL audit reports; 'none found' means no report with that agency's name is in the LRL file, which can also mean the audit exists but its summary was never filed. Matching is by name, so a city department can pick up a same-named county's report; check the report title column before relying on a 'yes'.

Not a finding that any agency is out of compliance. The Atlas is crowdsourced from public evidence and can be out of date; an agency may have stopped using ALPR. The state table covers five statutes and is not a 50-state legal survey. Not legal advice. Attribution: Atlas of Surveillance, EFF and University of Nevada, Reno, CC BY 4.0.
