Arizona Proposition 319, a legislatively referred statute placed on the November 3, 2026 ballot by Republican legislative majorities, would ban new photo enforcement systems for traffic violations while requiring local voter approval every ten years for programs under contract by December 31, 2026. Traders assign the measure an implied 79.5% chance of passage amid consistent Republican support for restrictions on automated enforcement, citing privacy, due process, and revenue concerns, alongside recent controversies over license-plate readers like Flock Safety that prompted cancellations in cities such as Tempe and an Attorney General review announced August 27. Opposition from some municipalities and public health advocates highlights safety data on reduced collisions, yet the measure's structure—preempting future installations while grandfathering compliant existing ones—aligns with patterns of legislative skepticism toward photo radar in the state. No major polling shifts or new endorsements have altered this positioning in the weeks since referral.
