If an average-speed camera system is used to detect speeding offences, it must be operated so that, when an instrument or computer forming part of the system registers that a vehicle has travelled between two detection points at an average speed equal to or greater than a speed set on the system –

(a) the system creates a digital incident file containing at least one photograph of the vehicle, or data from which a photograph of the vehicle is capable of being derived, taken at each of the relevant detection points; and

(b) each photograph so taken or derived, and included in the digital incident file, shows the following information:

(i) the serial number of the device;

(ii) the date on which and time at which the photograph was taken or the data was recorded;

(iii) the operator's code for the person who installed the device or was operating it when the photograph was taken or the data was recorded;

(iv) the location code for the detection point where the photograph was taken or the data was recorded;

(v) the speed-limit, or average speed-limit as calculated under regulation 14 , applying to a driver for the length of road between the detection points on which the vehicle was travelling when the photograph was taken or the data was recorded;

(vi) if the system is capable of detecting speeding offences in multiple marked lanes, the code for the marked lane in which the vehicle was travelling when the photograph was taken or the data was recorded.
