Can (specs) tell the difference between lgvs and cars?

Can (specs) tell the difference between lgvs and cars?
I would say that they probably can as they use ANPR.
This is something I’ve long wanted to know, infact I think I’ve brought the subject up before in relation to the A616.
Don’t recall having ever got a definitive answer.
Mostly just “well I always blast thru’ there in my artic on the limiter & have never had a problem.”
There’s a series of these cameras between Boston and Grantham on the A52. I have yet to pass through there doing HGV speed and am yet to get a ticket…
Probably tempted fate now! 
No.
Thankyou.
A chap I know reckons he got done on the A420 on a section between two cameras with weigh in motion sensors on them & according to him, they’re average speed cameras.
They may have weigh in motion on two of them but I doubt these cameras are linked as average speed cameras because they’re a long way apart with lots of junctions between them.
I hope the ones in the roadworks on the M5 between J13 & j14 southbound work though, they’re in a section restricted to 50mph with average speed cameras & as we were going down through there yesterday an artic flew past all of us like we were stood still. He must be a right ■■■■■■■■■ or very well paid if he can’t stick to the limit in a 2 mile section of motorway in narrow lanes.

I would say no after reading this:
As vehicles pass between the entry and exit camera points their number plates are digitally recorded, whether speeding or not. Then, by ANPR recognition, the images on the video of matching number plates are paired up, and because each image carries a date and time stamp, the computer can then work out your average speed between the cameras. There is no film used for SPECS
I’ve had a ticket in my car on the A616, so I know they work, but when I was on the bread runs, I used to go up and down there on the limiter and never heard anything.
BUT, I don’t anymore, it’s just not worth the risk, 40mph for me for the full length of woodhead (a628 and a616) even where there’s no scameras. If I have a queue behind me at the top (going from Tintwistle towards Barnsley), I’ll stop once I get just onto the downhill section and let people pass, but I won’t stop on the uphill sections, takes too long to get going and just end up with another queue before you get to 40mph. Coming the other way, there’s enough passing places so I just plod on.
There’s a speed camera on the A15 coming south from the M180 towards Lincoln which differentiates between cars and LGV’s. It’s 60 for cars but a single carriageway so 40 for trucks. Someone I know got a ticket for doing 50 in a truck caught by the camera.

Quite a few Gatso’s do, like the 1 on the A556, they’re different.
i go through the ones on woodhead at about 45,but probably quicker inbetween.so theyre either not switched on or they arent being enforced.
they certainly do know if you`re hgv or not because the information pings up with your reg.
not all roads are policed the same,it depends on different things like accident rate and wether or not the chief super is a petrol head 
some gatsos can also detect when you are over 7.5tonne by way of a pressure plate in the ground,if you look closely you can see where the road has been cut out to accomodate it.
i know drivers that have been nicked for doing over 40 on both the a1 north of newcastle and the a52 at grantham…both gatsos
