I dont mind about the roadworks speed limits but those mobile vans are just a money machine! No signs, no warnings,
You shouldn't be speeding, it's farcical that they have to put limit/camera signs near cameras anyway, the standard road signs should be fine!
and they dont even have signs to indicate the change in speed limit between the different sections of the road.
That would suggest that there's either no change, or that they're acting illegally and you should warn them of it.
There's no excuse for being caught speeding. While they may well be cash generating machines, they're only enforcing the laws that you should be abiding anyway, you're bang to rights if you get caught – grow up and accept the punishment.
before I realised I was now on a single carraigeway, about 500metres from the dual carraigeway I came off!
All that you're saying here suggests you have the observational skills of a blind rat.
