Automatic license plate reader systems; authorizing certain use by law enforcement. Effective date.

Oklahoma Senate Bill 857 authorizes law enforcement agencies (like police departments, sheriffs' offices, and the Highway Patrol) to use automatic license plate reader systems on public highways, but only for official criminal investigations - not for traffic enforcement. The bill requires agencies to obtain a Department of Transportation permit, adopt public policies covering data handling and oversight, and delete most collected data within 30 days unless part of an active investigation. It mandates strict data security (encryption, secure storage), prohibits selling license plate data, and bans using the systems to issue traffic citations. The law also requires agencies to verify matches before stops and maintain audit logs for accountability.
