An Early Analysis of Speed Safety Camera Program Rollout in California

This research brief offers an early analysis of California’s rollout of speed safety camera pilot programs under Assembly Bill 645 (AB 645). No California city has ever had an automated speed camera program before Spring 2025. Documenting the program set-up and early administration experience of the pilot cities will be informative in advancing road safety efforts if speed cameras become more widespread across the state. After examining research on speed camera effectiveness and best practices based on a review of national programs, the brief focuses on Oakland and San Francisco. Drawing on interviews with city staff, the brief evaluates how well California’s approach aligns with best practices in effectiveness and equity. It finds that AB 645 incorporated many instructive learnings from elsewhere, including income-based fine reductions and data-driven site selection. It also identifies areas for further improvement such as public transparency, alternatives to monetary penalties, approach to infrastructure investments, and enforcement challenges. The brief concludes that, depending on program improvements in these areas, speed safety cameras could become a valuable tool in California’s efforts to reduce traffic-related injuries and fatalities without exacerbating social inequities.
