Chandler police announced Saturday they are adding 12 new traffic cameras at intersections.

Officials warn the cameras will have to be tested, which will result in drivers getting flashed as they pass through the intersections. The testing phase is necessary to set the cameras, according to authorities. The systems will be active starting on April 1.
