Proposition 319 would prohibit state or local authorities from installing and using photo enforcement systems to identify people who violate certain traffic ordinances, including traffic signs, markings, signals and speed restrictions. It defines a photo enforcement system as a device that has radar or a sensor linked to a camera that produces images of a vehicle’s license plate to identify traffic violations.
Proposition 319 would permit local authorities that have installed photo enforcement systems prior to December 31, 2026, to continue using the existing systems. To continue use, local authorities would need to receive voter approval at a referendum in the November 2027 election.
Will Humble, Executive Director of the Arizona Public Health Association, joined “Arizona Horizon” to discuss this ballot measure.
If voters reject the continued use of photo enforcement systems, Proposition 319 would require local authorities to end operations of the systems within 90 days of the referendum.
If voters approve the continued use of photo enforcement systems, local authorities would be permitted to maintain operations for 10 years. Every 10 years after the voters approve the photo enforcement systems’ use, local authorities would be required to receive reapproval from voters to continue using the systems.
