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 local voter approval every ten years for any existing programs installed by December 31, 2026. Republican lawmakers advanced the proposal along party lines, citing privacy, due process, and revenue concerns, while Democratic opponents and several municipalities emphasize documented reductions in collisions and red-light violations at camera locations. Cities using the systems have taken neutral or opposing stances, and no major polling or campaign developments have emerged in recent weeks to shift the even split. The 50% implied probability reflects this balance between safety data supporting continued use and persistent statewide skepticism toward automated enforcement.
