Mobile Speed camera calibration?
Discussion
The son's been caught doing 57 in a 40 and received a letter through the post informing him of the deed!
But, the associated docs on GMP's website show the camera only to be calibrated up 150m, and the photos of the him in the actual car show him being pinged at 284m.
I'm not an expert what-so-ever in how these things work, but can something that's tested up to 150m be deemed accurate at 284m?

He can go to court and challenge it if he wishes, it will turn £100 and 3 points into fine and costs of around £700 and potentially more points.
He will need an expert to challenge the accuracy which I don't think you will find and the prosecution will produce their own expert (which you will pay for when they win) and they will.
Does he dispute that he was speeding or is he looking for a technicality to get him off.

No not disputing the speeding at all, just clutching at straws reallyHe will need an expert to challenge the accuracy which I don't think you will find and the prosecution will produce their own expert (which you will pay for when they win) and they will.

I've torn a piece off him already saying you deserve it and it'll teach you a lesson.
I actually don't think he's a daft driver (and has a dash camera fitted - if that actually prevents you from being 'daft'???), just one of those things, empty'ish dual carriageway and not thinking properly.

Have a look at agtlaw's posts in this thread. (As mentioned already by covboy)

"The Road Traffic Offenders’ Act 1988 allows for the Type Approval of devices to be used for the detection of the speed of motor vehicles ... Calibration of equipment is not a condition of Type Approval within the meaning of section 20(4) of the Road Traffic Offenders’ Act and, therefore, failure to prove calibration does not affect the admissibility of evidence. While it is not a condition, it is recommended that calibration is performed on an annual basis as normal routine maintenance of the device."
As mentioned above, as part of the Type Approval process, the Ultralyte 1000 was tested at a maximum range 454 metres. The manufacturer says the maximum range of the aforementioned speedmeter is 1000 metres.
In OP's case, the (recommended) annual calibration tested the device at distances of 25-150 metres. His vehicle was 243 metres from the speedmeter. 243 metres is well within the maximum range tested as part of the Type Approval process.
If he wants to see how this 'defence' will play out in court then read the eadt links I posted above.

Needs a comment from AGTlaw
I suspect the legal test will be what it is certified for, and the calibration ranges just confirm that its working as designed
Look up ^ ^ You must have been typing at the same time!I suspect the legal test will be what it is certified for, and the calibration ranges just confirm that its working as designed

I hope the lesson sticks.
Although the checks are per calibrated set distances shown, the type approval of the unit will be for x distance. Calibration will just be as per the manufacturers guidelines in accordance with type approval to guarantee overall accuracy, not just for the prescribed distances youve shown.
