2 Del. Admin. Code § 1205-2.0
DelDOT is specifically directed to identify intersections with high crash incidents as potential candidates for the placement of electronic red light camera systems. If a camera installation is performed on state-maintained streets or roads by an entity other than DelDOT, the Department must first approve such installation. In addition, the Department must approve the engineering of any new cameras installed. All intersections using a traffic control photographic system or other traffic light signal violation monitoring system must adhere to the exact duration of the yellow light change interval. This time period must be no less than the yellow light change interval duration specified in the design manual developed by the Department of Transportation.
