Red light cameras are automated devices installed at intersections to capture images of vehicles that run red lights. When a vehicle crosses the stop line after the traffic signal has turned red, the camera takes a photograph of the vehicle, including its license plate. This evidence is then used to issue a traffic citation to the vehicle's owner. These cameras are designed to enhance road safety by discouraging drivers from ignoring traffic signals. Many cities use red light cameras as part of their traffic enforcement strategies, aiming to reduce accidents and improve compliance with traffic laws.
