Right chap form talking to the guy at work on this subject the othr week.

The camera must be signed before the site (Not applicable if handheld trap). You can request to see the calibration certificate from the device that caught you. You can request to see the picture from the incident so you can assist the robbing bastards in identifuying the driver. If the image is at all vague you can say you have asked everybody that could have driven the vehicle on this date but saddly to no avail to identify the driver. You have then taken every reasonable action to identify the driver and you are very sorry but you can offer no further help on the matter.

Claim the car was for sale and the chap test driving it must have done it. his name was:

Freddie Kruger
17 Elm Street
Or at least that's what he told you
