I look at these cases for a living and the best action you can take when zapped by a speed camera is to request the following information:
1) When was the device calibrated? and where is its certificate. I will guarantee the police force will comply and show you a nice cert. Check the serial number of the device with the one that was used....it might be a cert for a different device!!!!
The problem with Calibration cerificates is that they only show you that the device was reading fine on the date it was calibrated. For example If i bought a car on the 1st January 2007 with a valid MOT certificate and let's say that on the 1st July 2007 the exhaust fell off, the tyres were below the legal limit, there was a crack across the windscreen etc, such that the car would fail an MOT, but now lets just say I continue to drive the sh*t heap around without being caught by the Rozzers until the 31st December 2007 when I get all the car fixed up and MOT'd. I then sell that car to you on the 1st Jan 2008 with a valid MOT cert and even give you the previous one to show what a nice little runner it has been............actually for the past 6 months its been a poor runner with a number of things wrong with it. You'd not have a scooby about that unless the most up to date MOT cert was accompanied by the mechanics invoice to show what was done to the car to make it right. Its the same principle with the Calibration certs for the speed devices........and I've yet to come across a police force that will ask the calibration service people for the engineers report aswell!!!!! Any brave barristers/solicitors should be making this point in Court.
2) The ACPO codes of practice for speed enforcement technology should be rigorously adhered to. They are not suggestions they are the bible and superceed the maufacturer's instructions. There are one or 2 police forces who have camera enforcement/safety partnerships who think the ACPO CoP do not apply to them.........wrong and I enjoy challenging them in Court as their Chief Constable signed up for it and it is a joy watching CPS being invited to bring in the chief to give evidence on why his own force policy is not being complied with.
3) The ACPO codes of practice give specific monkey see monkey do instructions on how to calibrate the devices before and at the end of each shift/tour of duty. This should be recorded on either a specific proforma and/or the officers pocket notebook, and/or the video (if being used). Just because this might not be in their statement doesn't mean it hasn't happened but you'll need to request this information. Watch the officer's/CPSs face if this information hasn't been recorded properly.
4) The speed measuring devices are bloody accurate WHEN USED PROPERLY and IN ACCORDANCE WITH ACPO CoP. There is a bloke who reckons to have proved, on the telly, that these(LTI20:20) devices are inaccurate but he wasn't using it properly or in accordance with ACPO CoP. He is a complete chump. (I work independently so I am not biased towards the police)
5) Word of unofficial advice.......don't speed in Cleveland force area as the chaps in the unit there are very very good and the Ex-Black Watch bloke who runs the unit is very proud of his procedures and working practices. Cumbria need to have a word with themselves about adhering to ACPO CoP!!!!

I am trying to confirm the average speed camera issue but it is possible that if you tuck in behind (too close) to a lorry or other vehicle the reg of your vehicle cannot be read by the camera, so it takes 4 readings and knows which cameras did manage to take the number plate, and therefore the distance between those cameras and therfore also the time and a calculation of the average speed between those two cameras is taken, i.e. if there are 4 cameras then you average speed could be between cameras 1 &4, or 1&2 or 2&4 etc etc. Best thing to do is not speed at all through the road works............the workmen(if there are any about will thank you). The guys you see speeding through them are either total idiots and haven't seen them or don't understand the principles behind average speed cameras and think that if they only pass the camera at the speed limit they can do any speed in between.
Hope you find this info helpful
