Interesting - most of the M1 roadworks is done ( from memory) on two cameras ,with 3 lanes ( again from memory)

And you know the cameras aren't covering the hard shoulder.
So now you have to remember... What is the speed limit? What speed have I been averageing? And which lane was I in when I passed the last camera?

No no no, it's all about safety. Yeah.

Funny thing is, didn't they swear blind that changing lanes would make no difference and still result in a prosecution? That explains the 'stay in lane' messages in roadworks. I thought it was for safety, clearly it is just to make sure they catch any speeders.

I've thought that was the case for a long time .

Truly unbelievable! It would appear the technology is capable, just disallowed for now.
So when will they sneakily close that loophole? perhaps when people have gotten used to changing lanes to evade the things? Don’t bet your license of something you won’t know about, far better to tailgate a truck (!!) when entering/leaving so the cam can’t see your plate at all!

What about zones with more than 2 SPECS cameras, say a two lane motorway, you would have to change back to your original lane for the third camera – would the system still get you?

No it wouldn't.

For SPECS to take a speed measurement it needs to clock you through two consecutive cameras in the same system, ie over the same lane. So as long as you swap lanes every time you pass a camera then you should remain undetected.

However, I have also heard that the next generation of SPECS cameras will address this, as the cameras will be capable of measuring (say) from camera 1 to camera 3 as well as from 1-2 or 2-3; but (as the article says) this technology is not yet type approved for installation.

It also means that every other zone is dead. With a four camera installation: A B C D, it can measure speed from A-B and C-D but NOT from B-C. And certainly not from A-C nor A-D nor B-D.

Thanks chaps, that's good to know.
I certainly won't be betting my license on this, but I will now be making use of the lanes (safely of course) - just to be 'safe' (especially after my experience on the M1)

I'm not entirely certain that this is true, ie whether or not a particular camera can simultaneously act as an "entry" and as an "exit" monitor.

However, even if your statement is entirely true, there is also the possibility that some cameras may be dummies; in which case the lane swapping strategy might not be 100% infallible, ie if you swap to L2 for what you think is camera "B" only for it to be a dud, then you return to L1 and pass through the real camera "B" and get nabbed.

For my own part, I routinely swap lanes whenever I pass through multi-lane SPECS installations and have done ever since I was wrongly prosecuted by an inaccurate one. I guess if you were to combine this with some judicious tailgating whenever the opportunity presented itself it seems this would be pretty near foolproof and you could go as fast as you liked!

Tailgating while exceeding the speed limit through roadworks doesn't seem like a very bright move!

I don't like the fact that SPECS is there, I think its counterproductive to road safety, but as long as it's there I'll do my best not to do the sort of speed that would get me a ticket.

I wasn't advocating it, merely predicting it!

That's exactly my approach too. Unfortunately it already got me one ticket, when what I believe to be a faulty SPECS system wrongly accused me of speeding.

I challenged this, in the belief that the fact that SPECS doesn't independently corroborate its readings would allow me to demonstrate that the evidence failed the "reasonable doubt" test, however doing so merely increased my fine from £60 to £500.

So in future I'll continue not to speed through roadworks, but I'll also swap lanes and / or tailgate, and indeed do whatever else I can legally do in order to protect my licence. Clearly if SPECS can't detect you then it can't erroneously cause you to be prosecuted.

I noticed this in the article

Med Hughes "It is irresponsible for motorists to deliberately seek to evade detection and speed.'
WTF is he on, is it irresponsible, to check your speedometer and try to stay within the limit, hence deliberately evadeing speed and detection, what a F*ckwit, of course if we watch our speed and avoid detection he doesn't get any money.

fatboytim

There was a report (speedcam , i think) about Northants SPECS, where those in the "know" drove in a particular lane ,"as the cams only targeted that lane " ---now fixed ,i believe.
