GATSOs with no lines on the road surface

[jjmurphy]

I am seeing more and more GATSOs that have no lines on the road in front of them. Does this mean, a. they are inactive or b. the enforcement folk don't need to confirm speed by physical measurements?

The latter

Sorry Sussamb, where did you obtain the information that the Gatso markings aren't required.
As I understand it to prove an offence of exceeding a speed limit still requires 2 sources of information:-
Gatso, Radar + physical photo showing vehicle set time apart over road markings.
Police radar : Radar readout + opinion of authorised operator.

I am aware photogrammetery can be used but there would still need to be known reference points visible in the photo and they would also have to prove the veracity of the photogrammetery program in court on each occasion

Are you sure they are Gatso type cameras and not Specs average speed cameras that are now appearing ?

The latest 2017 Siemens Safezone cameras for example, whilst aimed in one direction are actually trapping speeding in both directions. They don't use road marks afaik.

Similarly mobile cameras obviously can't use non existent marks.

Despite the legalities or otherwise of road markings, to miss-quote Dirty Harry "you've got to ask yourself one question: 'Do I feel lucky?' Well do ya, punk?".

I don't when it's a yellow box..

I think these questions are prompted by the recent Forum reference to this:-

"Meanwhile, last year, David Erasmus, from Llanelli, West Wales, successfully contested a speeding ticket when he found that the white lines painted on the road as a secondary measure of speed were too close together. Mr Erasmus measured the distances between the lines and found that they were three inches short; his case was dismissed".

The two earlier posters may well be wondering why, if white lines were once considered a necessary double-check, this no longer pertains as a safeguard against incorrect readings.

Mobiles have the police officers statement that you were speeding and the confirmatory reading of his laser jobbie = two sources of information.

I think the original question was about Gatsos with white lines in front of them, or not, (and not about mobiles or yellow boxes).

I used mobiles as an example that the technology is out there to measure accurate speed without road markings.

Plus, just to check whether the camera in question is a true old style Gatso.

My guess is that Gatso & Monitron probably do need reference markers.

As posted by Duddy above, one is photogrammetry.
