Camera Equipment and Site

Can you confirm the camera was in full working order on the date of the alleged offence? / Can you provide identification of the actual equipment used to record the alleged offence? / I would like to see all maintenance and calibration records for the identified equipment. 

A copy of the calibration certificate for the equipment used to detect the offence can be requested. The calibration certificate shows type, serial number and a West Yorkshire Police unique device number. Details of how to view the Public Access System are on your Notice of Intended Prosecution. All our devices are Home Office typed approved and are calibrated as per manufacturers’ specifications.


How do you know that the equipment is accurate?

First and foremost, all devices used are statutorily Home Office approved for the purpose.  This is a demanding process, first entailing extensive user operational trials on behalf of the Association of Chief Police Officers (ACPO) in different Police Force and Partnership areas.  if successfully completed, the submitted equipment is then subject to rigorous scientific examination by the Home Office Scientific Development Branch.

There is a requirement for all devices to be recalibrated by or on behalf of the manufacturer. Devices are also recalibrated if substantial work has been carried out making this necessary.

Other checking arrangements vary with the type of equipment, checks being carried out as frequently as appropriate. Checks are also carried out on each occasion a fixed camera is loaded or unloaded. Some devices (in particular fixed systems designated as 'automatic operation') have independent secondary check facilities. Others (in particular mobile systems designated as 'attended actively operated' ) confirm the opinion of a trained operator that the vehicle was exceeding the speed limit.


How can I be assured that the speed detection equipment is working within its specified ranges if you don’t hold exact information as to where the mobile vehicle was positioned?

The speed detection equipment is checked for range at the start of each day over a fixed calibrated length at the police station. It is immaterial where the vehicle is parked.


Can you please provide information on the training the operator has received and their understanding of that training, also can you please confirm that the operator was wearing a full police uniform and highly visibility jackets whilst operating the mobile camera?

All operators are trained by experienced and qualified professionals then tested on their understanding of the processes involved.

The operator works  from within the confines of a vehicle. These vehicles are fully marked and liveried police vehicles which are highly visible. There is no requirement for the operator to wear any particular garment if he is sat within the confines of a vehicle.


Was the vehicle / fixed camera highly-visible in rainy conditions, from 100 meters? Were the vehicle doors open or closed? If it had roof lights what was the major colour seen by an approaching motorist? Please provide evidence (including photo of liveried vehicle from 100 meters, operators check sheets/notes stating conspicuity guidance was met on that day).

Visibility conforms to the conspicuity guidelines set out by the Department of Transport. Note that non-compliance with these guidelines does not provide mitigation of, or defence for an alleged offence.


I am unsure of how you can confirm that the vehicle or fixed camera was highly visible and positioned so that oncoming motorists could check their speed.

The vehicles have high visibility “Battenberg” livery with the words police written down both sides, fixed cameras are covered in a reflective coating or painted yellow, though the appearance of the equipment used has no bearing on the offence. Signing and visibility are checked prior to enforcement commencing or a camera being deployed.


Among the Partnership, who actually purchases the automated enforcement systems used in your county? Who determines which manufacturer of enforcement systems is to be used? Who is responsible for the operations of the automated enforcement?

The responsibility falls between local authority engineers, the safety camera coordinator, partnership staff and individual camera suppliers.


Please send me a copy of whatever documentation is necessary to establish the financial involvement of your force in Speed Awareness Courses or similar provided to drivers caught speeding. Please also advise the legal basis for such involvement.

Any legal basis / documentation that we follow is from ACPO guidelines.


Can you please provide evidence that the location of the mobile speed camera was approved by West Yorkshire Police and the relevant Local Authority?

We do not document approval for enforcement locations as representatives from the West Yorkshire Police and Local Authority attend numerous site visits together prior to going live. This has no bearing on the validity of an alleged offence.



Why is the section of road covered by mobile speed cameras rather than other speed detection devices, is it due to collisions scattered along the length of the road, due to the time of day, or period in the year?

Enforcement type is chosen according to road layout, collision numbers and traffic flow data
