Gatso Photos -Speeding
Discussion
I've received a NIP for excess speed for class of vehicle, 68MPH in a 60MPH limit
I've been down today and looked at the photos. The first photo shows my van within the area covered by the white markings on the road,the second photo is outside of the area covered by the white markings.
As the second photo does not show the white lines then the distance travelled cannot be calculated using this method.
The police say they can still measure the distance I guess using a ruler to work out the distance?????
How accurate would it be - would the ruler have to be calibrated?
Anyone had any experience of this.
The officer stated that the white markings are to be extended shortly as they are too short for the camera site!!

I'm not a legal beagle or BiB but AFAIK there don't need to be any white lines at all. Many Truvelo sites I've seen didn't have any. The electronics at the end of the GATSO (or whatever) radar transceiver will get your speed to a very high accuracy. Compared to this, taking measurements off a small image is hamfisted and inaccurate, and I don't believe the police can enlarge or otherwise alter the pic as this could be seen as tampering with evidence.
Isn't the accurate speed determination imprinted on a GATSO photo, like the date gets on to holiday pics with some cameras?
If there are no white markings on the road then plod could use a transparent plastic overlay with markings on that, to the same scale that road markings would be on the pic. With accurate radar measurement I can't see why though, unless it's a failsafe should the imprinting mechanism go wrong and no speed appears on the film.
Surely the photo is needed to establish identity (number plate) more than anything else, and the double flash to reveal movement in the half-second gap? If there happened to be a parked car in a single photo, in an urban location say, it might not be clear which was moving with two vehicles alongside each other.
Hopefuly there's somebody who's got first hand experience of all of this and they can settle it.

And as I have said before
Goto www.pepipoo.com - if they are right there is no reason these days to get points or pay a fine if a scamera gets you. (It just might take the Government a bit longer to realise this)
BiB OTOH - well not much one can do about that!

Hi Nugent,
I spend a bit of time over there as well but can't find out the new hearing date due in september. It seems pretty important, do you know where/when it is and where I can find the info on Pepipoo?
It is beyond belief that anyone would rely purely on radar data alone to assess speed accurately. There is a strong need for a "sanity check" - this doesn't have to be so accurate, as you're only really looking for the radar system making a total muckup of the speed...
Not going into details, but while it is very accurate most of the time, periodically radars get things superbly wrong... I have seen instances of flying piers and flying boats as well as stationary airliners...

The white lines are used to corroborate the speed. If the lines are not in the second picture how can the speed be corroborated.
Agreed, but an officer with a radar or laser gun operating at various sites rarely or never has corroboration from white lines, but this doesn't stop successful prosecutions. I think white lines are in the "desirable but not essential" category and have a deterrence plus public acceptability angle too.
