Arizona voters will decide Proposition 319 on November 3, 2026, a legislatively referred measure that would bar new photo traffic enforcement systems statewide while requiring periodic local voter approval for existing speed and red-light cameras installed by the end of 2026. The slim 51% implied probability against passage reflects a partisan split, with Republican legislative sponsors emphasizing privacy, due process, and limits on automated enforcement, balanced against Democratic opposition and municipal arguments from Phoenix, Tempe, and Mesa that the systems reduce collisions and generate revenue. Cities have maintained neutral or supportive stances on current programs, citing safety data, while prior local restrictions such as Tucson's 2015 ban highlight recurring anti-surveillance sentiment. Competitive balance stems from these competing safety-versus-privacy frames and the absence of dominant statewide polling. Shifts could occur from campaign spending by enforcement advocates or privacy groups, law enforcement endorsements, high-profile enforcement incidents, or turnout patterns among suburban and urban voters before Election Day.
