Castaic FAQ
Can I find out if my license plate was scanned?
Yes, partially. The California Supreme Court ruled ALPR data is subject to Public Records Act review with redaction. File a request with the Sheriff's Department citing ACLU v. Superior Court 2017 to obtain hits on your plate.
How long does the County keep ALPR data?
Currently up to five years per Sheriff policy, longer than many counties. SB 34 requires the policy be posted and audited annually, but does not set a maximum retention. Civil liberties groups continue to push for shorter limits.
Los Angeles FAQ
How long does LAPD keep my license plate scans?
LAPD retains automated license plate reader data for five years under current policy, regardless of whether the plate matches an investigative hit list.
Can LAPD share ALPR data with ICE?
California Senate Bill 54 limits state and local agency cooperation with immigration enforcement. LAPD has been audited for ALPR data sharing; current policy prohibits transfers to federal immigration authorities.
