Advocates has expressed strong opposition to Senate Bill (SB) 1019 and Senate Concurrent Resolution (SCR) 1002 in a letter to members of the Arizona Senate. SB 1019 prohibits the use of automated enforcement (AE) systems, an effective technology to deter speeding and red light running, and SCR 1002 seeks to do the same through a referendum. AE is proven to deter speeding and red light running where cameras are present.

A study by the Insurance Institute for Highway Safety (IIHS) found that speed safety cameras alone resulted in a 19 percent reduction in the likelihood that a crash caused a fatal or incapacitating injury. Red light safety cameras show similar safety benefits. According to the Journal of Safety Research, rates of fatal red light running crashes were 21 percent lower and all fatal crashes were 14 percent lower at signalized intersections in cities with camera programs. Conversely, cities that took down their red light safety cameras experienced a 30 percent increase in deadly red light running crashes and a 16 percent increase in fatal crashes at signalized intersections overall.
