Genuinely true story.
I did my class one HGV test 20 years ago and failed for driving at 40mph in a 50mph zone.
The examiner said it was a clear day, and I should keep up with the traffic and there was no reason I shouldn't have been doing 50, so at the time did appear to be a target and not a limit! I was fairly annoyed as I thought I was playing it safe.
I passed a week later and made sure I did 50 down the same stretch of road with the same examiner.
To be on the safe side, always slow down under motorway gantries!
Watch out in Bedfordshire. They have average speed cameras through 30mph villages, and are not signposted, and the cameras are impossible to spot. There is a very small white tick or V mark on the road.
I had a friend who worked for the Bedfordshire council who said half the council staff have been on speed awareness courses! Slow down, BEFORE you get to the 30, and don't speed up until you have LEFT the 30 as its easy to do both.
