Thanks all really useful info. Could be a very costly error that was honestly not done intentionally.

Thanks johnjordan, I shall take it as far as I can if need be.

Hi all, I wonder if you can help me. I have received a speeding ticket saying I was caught speeding at 74mph in a variable speed zone reduced to 40mph. I was travelling on the M69 junction 7-8 With my wife and child, I’m always a careful driver and my wife normally spots reduced speeds if I haven’t and says slow down. None of us have seen any changes on the gantry, no traffic built up and no lane closures, the road is clear. I have signed to say it was me driving but 4 weeks later no penalty notice yet to tell me my fate. I have done the same journey again weeks later and the same spot the speed was reduced to 40mph again but this time major traffic. I can understand the 40 mph on this occasion but nothing like this on my first trip. Could you give me an idea as to what I should expect as a fine etc please. I did write a letter explaining the above and have a clear licence but I presume this will have no affect. Thanks all.
