The Road Traffic Act 1991 provides highways authorities with the power to install and maintain, on or near a highway, structures and camera equipment at traffic-light junctions to detect vehicles failing to comply with a red traffic light. A total of 600 red light cameras were operating within the National Safety Camera Programme for England and Wales on 31 March 2007. Since 1 April 2007 the Department’s guidance has allowed local authorities greater freedom to deploy red light cameras in order to prevent or reduce such incidents.
