Hi Russ
Wasn't on the way back from the Ace was it? 'Twas good to see you again. Let's hope they don't take objection to your number plate as well.
I think Pepipoo is the place for speed fine related info.

Assuming you were caught by lidar (laser): I believe the units should be returned to the manufacturer for annual calibration (I doubt the manufacturer would own up if they found such a fault). Alignment checks should be done by the operator at the start and end of each session.

If you really believe you've been falsely accused, then the following link may shed some light as to why:

This subject made front page news in the Daily Mail a few months ago.

As I understand it a radar reading (if that's what it was) isn't allowed to be used as evidence where two vehicles are travelling close together as each vehicle's signal can interfere with t'other....

Anyone know if I'm talking shite?
