SB 152: Changes Automated Vehicle Identification System Usage - Colorado

Rerevised → Final Act · 6 edits · May 21, 2026

MODERATE

The bill clarifies that automated vehicle identification systems (AVIS) used for traffic enforcement are distinct from automated license plate readers (ALPR) used for criminal investigations. It adds specific definitions for mobile AVIS and establishes new public notice requirements, including website announcements and physical signage, before these systems can be deployed to issue violations.

Scope change

The bill explicitly limits its scope to AVIS for civil traffic enforcement, ensuring it does not regulate or affect the separate use of ALPR systems for law enforcement purposes.

DEFINITION

Added a specific definition for 'Mobile Automated Vehicle Identification System' to cover systems mounted on vehicles like vans or SUVs that can be relocated between enforcement sites.

Clarified that the term 'Automated Vehicle Identification System' does not include Automated License Plate Reader systems.

REQUIREMENT

Mandated that agencies must announce new AVIS deployments via their websites and social media for at least 30 days prior to use.

Required physical signs at each AVIS location announcing upcoming use, with specific lettering height requirements for visibility.

Established a rule that only warnings (not penalties) may be issued for the first 30 days after a new system is installed or deployed.

Required permanent signage at least 300 feet before the start of any designated automated vehicle identification corridor.

MINOR

The bill was re-revised to include a new sponsor, Duran, and updated the reading status to reflect amendments adopted in the Second House. Substantively, the text removed a section defining mobile enforcement devices as those used for temporary flexibility in high-risk areas, while retaining the definition that devices mounted to trailers are considered mobile if moved within 72 hours.

Scope change

The bill's scope regarding the definition of 'mobile' enforcement devices was narrowed by removing the clause that covered temporary flexibility in high-risk traffic areas or shifting traffic patterns.

DEFINITION

Deleted the definition stating that a device is generally used to provide flexibility for temporary enforcement in high-risk traffic areas or shifting traffic patterns.

ADMINISTRATIVE

Added Senator Duran to the list of House sponsors.

Updated the document header to indicate this version includes amendments adopted in the Second House rather than just on Second Reading.
