SB3257
VEH CD-ALPR-RECORD RETENTION
TL;DR
Illinois Senator Laura Murphy's SB3257 updates the state's rules on automated license plate readers (ALPRs), redefining them to explicitly include camera systems using computer algorithms and setting strict retention limits: records must be archived after 90 days, require agency head approval to access after that, and be destroyed after 5 years. The bill also blocks out-of-state agencies from searching archived records older than 90 days.
How This Might Impact Your Business
Companies that manufacture, sell, or operate ALPR technology for Illinois law enforcement (Flock Safety, Motorola/Vigilant, Rekor, Genetec) would need to update their platforms to support 90-day archiving, 5-year automatic deletion, and access-approval workflows tied to the agency head.
The updated definition explicitly captures AI-driven camera systems using computer vision algorithms, not just traditional 'electronic devices,' which brings modern AI-based ALPR vendors clearly under Illinois regulation.
Private ALPR operators (parking lots, HOAs, retail centers, repo companies) that share data with Illinois law enforcement fall under the definition and would inherit these retention rules for shared data.
Vendors must build technical controls to block out-of-state agency searches of records older than 90 days, meaning multi-state data-sharing platforms need geo-fencing and query restrictions specific to Illinois data.
Existing prohibitions still apply: ALPR data cannot be shared for immigration enforcement or to investigate reproductive health care, and out-of-state sharing requires written affirmation of compliance.
The bill is still early (introduced February 2026, re-referred to Assignments), so timelines for compliance are not yet set, but Illinois has a track record of passing ALPR restrictions.
No direct monetary penalties are specified in this amendment, but violations of the underlying Vehicle Code section carry existing enforcement mechanisms and reputational/contract risk with law enforcement clients.
What Should You Do
If you sell ALPR or computer vision plate-recognition tech in Illinois, have your product team map current retention defaults against the 90-day archive and 5-year destruction requirements and scope the engineering work now.
Legal teams at ALPR vendors and data-sharing platforms should review out-of-state query architecture to confirm you can technically enforce the ban on out-of-state searches of archived records.
Private operators (retail, parking, HOA security vendors) sharing plate data with Illinois police should audit contracts and data flows to confirm you can comply with the retention and access-approval rules downstream.
Track SB3257 through the Illinois Senate Assignments Committee; assign someone to monitor for a hearing date and companion bills in the House.
Review your existing written declarations from out-of-state law enforcement partners to ensure they meet the affirmation requirements already in Section 2-130.
