The Fairfax County Police Department continually reviews its policies and practices to ensure LPR technology is used responsibly, effectively, and in a manner that reflects the values of the community it serves. The use of license plate readers is governed by Code of Virginia 2.2-5517 and FCPD General Order 424, Automatic License Plate Reader Program.

How the FCPD Conducts LPR Audits
Every LPR search is tied to a case and permanently logged. Two independent review tracks examine those searches before anything reaches the Commander. Audit reports are on a monthly cadence.
- All users must list a case or event number and a crime type when they conduct a search.
- All searches are logged into the Audit portal and cannot be removed.
- An audit team continually reviews 100% of the searches conducted by the FCPD.
- The team looks to identify anomalies within search patterns and user history.
- An AI audit tool surfaces search patterns based on pre-determined criteria.
- The AI audit is reviewed separately from the human review.
- The audit team provides a monthly report to the FCPD Commander for final review.
- The FCPD Commander is prohibited from conducting any LPR searches, which is separately reviewed.
- Any user who did not follow the strict system rules set forth by the FCPD must provide written documentation to justify their actions.
- That user is removed from the system and must re-attend in-person training.
- If violations of law or departmental policy are found, then a prompt investigation will begin.
