Arizona Proposition 319, a legislatively referred measure placed on the November 3, 2026 ballot by the Republican-controlled legislature, would prohibit new photo traffic enforcement systems statewide while requiring periodic local voter approval for existing programs under contract by December 31, 2026. The measure advanced on party-line votes in the Senate (16-12) and House in early 2026, driven by Republican priorities around privacy, due process concerns, and limits on automated fine revenue. Cities such as Phoenix, Mesa, and Tempe have opposed it, citing documented reductions in collisions from existing cameras, but face a statewide electorate where similar enforcement restrictions have historically drawn majority support. With roughly two months until the election and no major counter-campaigns or polling reversals reported, trader consensus at 79.5% for passage reflects the partisan makeup of recent Arizona elections and the structural advantage of legislatively referred measures aligned with the majority party.
