Automated Traffic Enforcement Safety Devices Toolkit

Traffic signal showing red light

Enabling Legislation: Public Act No. 23-116

As of October 1, 2023, Connecticut towns are authorized to use Automated Traffic Enforcement Safety Devices (ATESD) at locations within school zones, pedestrian safety zones and other locations (upon an ordinance adopted by the municipality in accordance with the Act's requirements and a plan approved every three years by CT DOT.

ATESDs will detect and collect evidence of alleged violations of ordinances by recording images that capture a number plate, date, time, and location of a motor vehicle that exceeds the posted speed limit by ten or more miles per hour, or fails to stop such vehicle when facing a steady red signal on a traffic control signal.

The intention of this legislation is to empower Connecticut municipalities to equitably improve roadway and pedestrian safety in their communities.

  • Devices that detect violations of municipal traffic ordinances may issue a citation, which will be mailed to the vehicle owner's address within 30 days after address confirmation by the CT DMV
  • If a violation occurs within the first 30 days the enforcement device is working, the citation will result in a written warning
  • The fine for a first violation may not exceed $50 for a first offense and not more than $75 for a subsequent violation

CT Department Of Transportation (CTDOT) is required to develop, and revise as necessary, guidance for municipalities. Guidance will include ATESD plan development and submission, criteria used when evaluating plan submitted for approval, and ensure that the devices are installed in locations where they are likely to improve traffic safety and distributed equitably throughout the municipality

The National Highway Traffic Safety Administration (NHTSA) and the Federal Highway Administration (FHWA) have observed that the presence of ATESDs can supplement other speed management techniques to alter driver speeding behaviors, and FHWA has identified these systems as a proven safety countermeasure that can reduce roadway fatalities and injuries by 20-37% (Montella et al, 2015; Li et al, 2015).
