This morning early, stretch of local road I know well with three cameras within a mile of each other, 40 Mph limit. I go through at less than 40 it flashes twice, can I prove my speed using Digi Tacho download…

NO
Tacho is not proof although i suppose it could help.
If you really weren’t speeding then the flash may well not be for you. If you get a summons then ask for the pic and check for high speed birds.
Wasn’t the A435 through Coughton was it?
Each safety camera has a calibration certificate and is calibrated every 12 months by the manufacturer. The safety camera operator carries out a self-test before and after each use of the camera. Evidence of this self-test and the calibration certificate form part of the prosecution case and will be presented before a court if necessary.
I’ve had this happen to me a number of times, nothing will happen as you were below the speed limit at the time.
Some times they pick up something that makes them think that there is a speeding car. It imght be a bird or reflection off some glass nearby. This has been proven in various documentries In any case. They will not take you to court because they are checked before they issue a NIP.
One near me can’t cope in the fog. I went passed it about a year ago in the fog and it was firing off every minute or so.
It was the A5 through Brownhills, west bound… 
Am I right in thinking that you went through all 3 cameras at 40 or less and only one flashed
If yes, then the tacho can be used in supporting your claim that one camera was faulty as it will show that all 3 were passed at the same speed and the other 2 did not flash
IIRC, when tacho’s first came in, the charts were allowed to be used as defence but not in prosecution.
Since they’ve installed the average cameras at Wetherby, there is a temporary 50mph limit. Now what I can’t understand is that when I’m doing 50 there are wagons doing atleast 56mph and cars going even faster.
How can they do it I mean its asking for trouble. All you need to do is travel North and South bound get caught four times and you’ve lost your licence!!!

I think it’s the other way about now

Because if your speedo is showing 50 you will only actually be doing around 46 - 48 mph, maybe even less, and the ones that are showing 56 will only be doing around 52 - 53, again maybe less. The camera will not fire below 57 so very few of the vehicles going through will actually trigger it, the ‘50’ you are doing will be about 10 mph less than the trigger speed. If a camera was set to trigger at the exact speed limit or just above the amount of offences generated would swamp the departments which issue tickets. All speedos, over read, even on brand new vehicles, as the cost of manufacturing a totally accurate device would be prohibitive and they can over read by anything up to 10%, the main reason why the ACPO guidelines work on 10% +2 mph.
as of today swindon have covered all the speed camaras, as it was costing them 350k a year to maintain, now there gonna spend there money on something else.
Wonder if anyone else will follow suit.

Yes Rog just the one flashed, we all know this road well and always pass just fractionally less than 40…

So in doing the same speed through the other two makes the point that one was faulty.
If you went through all three cameras at 60 and all three went off, would you get done 3 times cos technically you were only speeding once 
BTW your safe* to speed through Swindon now. they turned the cameras off at last
*but watch out for the rozzers, and the mobile cameras.

Differing views on that from BRAKE and the IAM -
"We’ll be working with the road safety partnership, investing in education programmes [and] working with the Institute of Advanced Motorists to improve driver training facilities and with schools and colleges.
“We are also trying to deliver improved programmes for drivers who have been caught transgressing the speed limits,” he said.
“At the end of the day all these devices do is take pictures of people breaking the speed limit, they’re not actually managing the speeds and they’re not educating people.”
Tim Shallcross, from the Institute of Advanced Motorists, said: "Cameras are not the total solution and 10 out of 10 really to Swindon for reviewing the expenditure that they put into the budget for road safety.
“If Swindon can show that they have produced a definite reduction in casualties by diverting the money to other resources from some cameras, then that’s setting a good example for others to follow.”
But Helena Houghton from Brake said: "We’re strongly opposed to the decision. We think it’s a dangerous experiment with people’s lives.
“By removing speed cameras you are removing a deterrent. They are crucial in lowering death and injury rates.”
Apparantly large flat backed vehicles that are vibrating can sometimes send spurious returns to a GATSO.
So that means its a good idea to make sure if your transporting adult toys, to ensure the batteries are removed before transit then.
