IL SB3320

Defines "automated license plate reader" (ALPR) as a camera system using computer algorithms to convert license plate images into searchable alphanumeric data, mounted on law enforcement vehicles or stationary locations for investigative purposes.

Prohibits ALPR users from sharing information with any jurisdiction to investigate or enforce laws that deny reproductive health care services or permit detention based on immigration status.

Requires written declaration from out-of-state law enforcement agencies affirming they will not use ALPR information in violation of sharing prohibitions before Illinois agencies may share such data.

Establishes 5-year maximum retention period for ALPR detections by law enforcement agencies, with mandatory archiving after 90 days unless relevant to ongoing investigations or pending trials.

Prohibits archived ALPR records older than 90 days from being searchable by out-of-state agencies and requires all records to be destroyed after 5 years unless needed for ongoing investigations or criminal trials.
