I've recently received a speeding ticket for driving at 57mph in a 50mph zone on the "A41 Chetwynd Aston towards Newport". As someone who generally keeps within the speed limit, I'm a bit miffed at receiving my first ticket in over 30 years of driving. Also, using the Home Office guideline of Speed + 5mph + 10% , that puts me bang on the borderline. Now, I've been wondering a bit.... If my speed was 57mph, then it was likely that I thought that the speed limit was 60mph, which would be the norm for that particular class of road. If I've missed a sign, then fair enough, I should have been more alert. But then again, what if the copper with the speedcam has slipped up and mistakenly reported the limit as 50mph instead of 60mph? I've just looked on a speedcam website and they report that mobile cameras are often used on this stretch of road and that the limit is 60mph. Of course, it may be out of date. So, is there anybody who can confirm what the speed limit is on this particular bit of road? Thanks in advance.
