speeding ticket (NIP)

[F4celess]

ref the post about motorway gantry cameras saying do 60 and flash you doing 70

a speed limit is only enforceable if the speedgate sign is surrounded by a red circle as per the road signs you see. If it's a smart m/way then they have the ability to do this on the electronic signs but if any m/way sign just states a figure e.g. 60 and it's orange with no red circle then its only an advisory speed and you cannot be done for speeding

Yeah, tend to see these flash up on the motorway where they warn of queues ahead, or even "traffic calming" ahead. M25 is a good one, north of Heathrow.
I do wonder if the Cameras on the gantry then know this sudden change of speed limit based on the flashing sign that pops up, so will flash you doing 61mph, while you are slowing down from 70... or they are "set" for 70mph. hrug
