HCR 2004 Arizona House · 57th Legislature - Second Regular Session

photo enforcement systems; prohibition.

HCR 2004 is a proposed referendum measure that would prohibit the use of photo enforcement systems for traffic violations in Arizona. It defines "photo enforcement system" as devices combining radar/sensors with cameras to capture license plate images for identifying traffic lawbreakers. If approved by voters, this measure would amend Arizona law to ban such systems, directly affecting law enforcement agencies and traffic enforcement practices. The resolution requires voter approval to become law, as stated in its preamble.

What changed between versions

Introduced Version → House Engrossed Version (03/03/2026) · 5 edits · Mar 3, 2026

MODERATE

The bill was reformatted from an 'Introduced Version' to a 'House Engrossed Version,' which standardizes the layout and header information. Substantively, the text of the bill was significantly simplified and corrected; the original version contained a massive, unrelated list of traffic definitions (like 'explosives' and 'gross weight') that were removed. The final version now clearly defines 'photo enforcement systems' and establishes a strict voter approval process requiring local authorities to seek public consent before continuing to operate these systems.

Scope change

The scope was narrowed by removing irrelevant statutory definitions unrelated to photo enforcement, focusing the bill strictly on the regulation of photo enforcement systems and the requirement for voter approval.

DEFINITION

Removed a large block of unrelated legal definitions (e.g., explosives, gross weight, intersection) that were present in the introduced version but did not belong in this specific bill.

Refined the definition of 'photo enforcement system' to explicitly state its purpose is identifying violators of traffic laws or ordinances regarding excessive speed or failure to obey traffic control devices.

REQUIREMENT

Established a mandatory voter approval requirement, forcing local authorities to seek public consent at the next general election to continue operating photo enforcement systems after December 31, 2026.

TIMELINE

Set a specific deadline of December 31, 2026, by which local authorities must have a signed contract to operate a photo enforcement system to remain eligible for a voter vote.

ENFORCEMENT

Created a mechanism to cease operations within 90 days if voters fail to approve the continuation of the photo enforcement system.
