HI
IS IT TRUE THAT ALL THESE "SAFETY CAMERA VANS" ETC. ONLY PROSECUTE YOU IF YOU EXCEED THE 10% PLUS 2 MPH MARGIN? SO IN THEORY 35, 46, 57, 68, 79 WOULD BE FINE? BUT NOW PEOPLE ARE COLLECTING 3 POINTS FOR 35 IN A 30. THEREFORE, IS THIS MARGIN IS NO LONGER APPLIED?
ANYONE HAVE ANY THOUGHTS?

no need to shout, and they aren't "scamming" you, they are fining you for breaking a law. This law/position of camera's is debatable but the fact still remains.

The 10% + 2MPH no longer exists, the tolerance has been dropped quite dramactially indeed, although I am unsure as to what that tolerance actually is.

As far as i'm aware you can be charged for being 1 mph over the limit, even though a speedo can have a 10% margin of error.

this is a mis conception. The speedo error has to be with -10% +0% ie the speedo will NEVER read under, you are always traveling slower than the indicated speed. Varies per car and per speed for any given car but typically will be around 3 to 5%.

You can be done for a fraction of mph over the limit, the main issue concerns the accurancy of the measurement which is typically +-1mph on most detection systems. So in practice anything over +2 is fair game. Scamera's tend to be around 5% over police stick nearer to the 10%+ is what I've concluded.

Maintaining one's speed at the limit +/- 1, 2, 3, 4 or 5 mph at all times is a practical impossibility. Few roads are completely level, as you go up the speed naturally falls, as you go down it rises. Even speed control doesn't compensate immediately to changes of level.

1mph over the limit (Brunstrom territory) might be breaking the law, but (as posted here before) maintaining one's speed to that degree of criticality requires one's concentration to be on that aspect of driving and not on others, such as pedestrians (jay-walkers), other cars, road signs ...

Having said that, read this separate thread and consider ...

Technically speaking 1 mph over the limit then the offence of speeding is there, but believe ir or believe it not BiB are more than fair.

Guidlines on enforecement fiqures have been made by Bib heads (ACPO) which roughly equates to 10 per cent plus 2mph

Page 6 of enforcement policy. Note the small print that it still remains the discretion of the individual officer.

(Presume Mike/Tony there has been no change)

Don't disagree, but a camera could be set to this level and with little human intervention could in the future see people getting NIP's for 1mph over the limit.

The thing to watch out for with this is that Brunstrom is ACPO's Road Policing Chairman. So expect these guidelines to be revised when the revenue stream to his "Business Unit" starts to dry up...

Playing Devil's advocate here, some would argue that it's a speed limit, not a target. If it's too hard to keep the needle bang on 30, the 'speed fascists' would argue that you should keep it on or around 25 mph instead, to give yourself margin for error.

10% + 2mph was always discretionary anyway, it was never statutory.

Or to put it another way, it always used to be a generally-accepted rule of thumb, and as such never something to be relied upon.

It's much the same to the fact that you can be prosecuted under the Road Traffic Act for having an empty washer bottle. Not something you would expect to actually get prosecuted for, but within the law nonetheless.
