The colour they are painted has no bearing on whether they are live or not.
HTH
Back it up .HTH
All of the installations were grey, they are now being changed to yellow. The only significant difference between the grey and yellow cameras is the colour. The colour is being changed as maintenance or installation affords the opportunity to apply the yellow colour.
I think I've said it once in this thread already, and if not then somebody else probably has, these things are going to catch far more people as they can also recognise the type of vehicle that is driving and can therefore apply different limits where appropriate. Cars with trailers or caravans might confuse them a bit but trucks, buses and vans that previously weren't recognised by the gantry cameras specifically won't.
The last time I was going Southbound on the M1 near Leicester one of the Northbound cameras was flashing regularly with no evidence of anyone going particularly quickly, the HGVs/Transits were setting it off.
I don't remember having seen any other than in variable limit sections of Motorway, which are turning up everywhere anyway. They are enforcing the variable limit but usually also seem to be enforcing the NSL when a reduced limit isn't in force.
According to my radar detector, virtually every one of them is live. The 3 cameras on the pole prior to the hangman's gantry with the HADECS check the numberplates to determine the type of vehicle then the camera will trigger at the relevant limit for the vehicle.
Hoorah.
If I have this wrong I am happy to be corrected. Very happy.

Yes they were in the managed motorway section coming north out of Birmingham on the M6. However, the cameras were mounted on a bracket on an umbrella handle massive pole supporting a single square-ish message board, not a gantry spanning the carriageway.
In the dark these will be impossible to see, and could be a game changer wrt my approach to driving on the motorway.

I'm only on the M25 every other week but have noticed not as many speeds over 70mph.In the dark these will be impossible to see, and could be a game changer wrt my approach to driving on the motorway.
Last week twice, C/C set to 70 for most of the journey. VW T5 van so i should know soon enough if the cameras are picking up on vehicle type.

The cameras are pointed at the VSL signs to produce a photographic record of the limit in force at the time of a contravention.According to my radar detector, virtually every one of them is live.

AFAIK, there isn't anything needed to determine type of vehicle other than a lookup in the DVLA database when the plate is read.
The radar will be on all the time, not just when there's a VSL in place, but the trigger speed is >85mph (probably quite a bit more) when NSL applies. There have been reports of notices issued for 100 and above but I don't remember seeing any in the low nineties. As always, make your own mind up rather than relying on anything you read on forums.

Yes, I have seen some on their own 'stand' but mostly they are on a hangman style support to the left of the gantry with the speed limit signsIn the dark these will be impossible to see, and could be a game changer wrt my approach to driving on the motorway.

Those cameras (3 side-by-side ) on a pole are also the ANPR to read the plates as far as I am aware. AFAIK, there isn't anything needed to determine type of vehicle other than a lookup in the DVLA database when the plate is read.

You'd have to be a bit daft to chance going through them at more than 78 though. They may not trigger until 85 or more but I doubt it, the standard tolerance for NSL would give a 79mph trigger. Why would they go higher with the current mindset on speed? The various sources I've read are all suggesting that at present the gantry or HADECS cameras if used to enforce NSL are being set at 79.

Some of us have tried, but you seem happier to believe your own version of reality 
The thing I can't find confirmed or denied is whether they differentiate between class of vehicle. As to prosecutions for exceeding the 70mph limit when there is no active reduction in force, there are numerous reports from BBC, The Times etc regarding prosecutions with very non-committal responses from the relevant constabularies as to what their trigger speeds are. Thinking you can happily travel around below 85 wouldn't be very sensible from reading what they say.cmaguire said:

Here's something for you though. NSL is enforced, why wouldn't it be?
Source: me. Why ask for more?
