By the way Mike have you been down Houghton cut lately?
They are doing roadworks and have put the speed limit down to 30! (it's a dual carriageway)

Now a speed camera van hides at the bottom.
I was doing 34 today do you think I will get a ticket?
Not been up there since Christmas day, don't seem to vist swmbo family very often, no particular reason.
34, you might just get away with it, 10% plus your speedo will read low at that speed, I think. 
The rule used to be 10% + 2 MPH, i.e. you had to be doing 35 to get a ticket, nowadays though in the interest of revenue raising I am not sure what discretion is applied, if any, it is so easy to rely on computer generated tickets. Totally off topic, in early September I drove from Dover to Durham, 353 miles, and did not see a single police vehicle of any description, not one, anywhere. Are they relying too much on cameras, not a single marked car to deter dangerous drivers who tailgate, stay in lane 2 for 30 miles, don't use their lights in rain / fog etc. I for one would prefer a visible police presence rather than constantly looking for cameras. What do other members think ?
