Fixed cameras are used to detect speeding offences and red light violations. They have been installed to counter very serious collision problems, to protect vulnerable road users and to encourage driver compliance with the speed limit and red lights. They have also been established to counter anti-social speeding when concern has been expressed by residents groups. They have never been installed as a means of generating revenue.
Fixed cameras have been established in accordance with the relevant criteria at the time the length was set up. All our enforcement is set up with high visibility deterrence in mind. Our camera housings have a reflective yellow coating and are placed in conspicuous locations on signed operating lengths. We do not operate covertly.
West Yorkshire Police use a mixture of fixed camera types across the county, all of which are approved by the Home Office and are calibrated before enforcement. They are placed in areas that have been identified as high risk of collisions, following road collision analysis carried out at District Council level. Speed and location surveys are carried out by Police and district engineers to ensure enforcement is possible and necessary.
Not all cameras have line markings on the road, some use radar with no forms of road markings, some use embedded sensors in the carriageway, whereas some have visible white lines before or after the camera. These white lines are used during processing, they do not calculate the speed, the speed travelled is measured by the camera equipment, the lines are only used as a secondary check during the processing of the offence.
Compliance with these rules has no bearing on the enforcement of offences detected by the use of safety cameras. Non-compliance with these rules and guidelines does not provide mitigation of, or defence for, an alleged offence committed under current UK law.
