There are no SPECS speed cameras permanently installed on the motorway network. Temporary SPECS cameras are used at some roadworks on the motorway network. The number varies according to the roadworks in place at any one time.
Electronic message signs on motorways are not fitted with speed cameras. CCTV cameras are fitted to a number of electronic signs to assist the Highways Agency in assessing the effectiveness of the signs in altering driver behaviour in response to the messages.
