About Photo Enforcement

First implemented by DPS on a small-scale in 2007, the agency’s Photo Enforcement Program now consists of dozens of automated photo-based speed detection systems along the state highway system. The systems, both stationary and mobile, are located in both rural and urban areas with a majority of the systems positioned along stretches of roadway where the volume and severity of speed-related automobile crashes was high prior to system deployment. In order to encourage voluntary compliance to speed limits in areas where the systems are deployed, every photo enforcement zone is preceded by at least two highly visible advisory signs that indicate the presence of a photo enforcement system ahead. This gives a motorist every opportunity to slow to the speed limit prior to passing the system that, if activated, could result in the motorist receiving a violation notice, and fine, in the mail. Although the DPS Photo Enforcement Program is relatively new in Arizona, preliminary data suggests the program is achieving its goal of reducing the volume and severity of speed-related crashes along the state highway system.
