Relevant To: ALPR presentation (August) — state-by-state data retention comparison
Verification Status: Verified
Notes: Confirmed via screenshot: a “License Plate Reader Data Retention Map” — a state-by-state choropleth map of statewide ALPR data retention limits as of June 2026, color-coded by retention window (30 days or less, 31-90 days, 91 days-1 year, over 1 year, has a law but no deletion deadline, no ALPR law). Cites state statutes and NCSL (National Conference of State Legislatures) as sources. Notably flags Oregon-relevant context is absent (would need to check where Oregon falls), and includes footnotes clarifying CA’s limit applies only to Highway Patrol, CO is a passive-surveillance state, and NJ relies on a 5-year AG directive rather than statute. Useful reference visual for the August ALPR presentation’s comparative state-law section — recommend independently spot-checking a few states’ figures against primary statutes before reproducing the map directly, per BPA verification standards, since this is vendor-published (VPN company) content.
