The theory is commonplace, but I doubt the practice - not least
because it's entirely possible for two nominally visually identical
vehicles (and certainly very similar in overall outline or

Basically, I just don't think the cameras are intelligent enough.
Well, the cameras don't need to be that intelligent. The software for
working out the fines can do a final check on whether the speed is
legal for the vehicle in question.

So you're suggesting that the cameras in a 60 limit single carriageway
NSL should take a photo of every vehicle doing over 40mph, in case they
might be HGVs?

No, just that if, as suggested, they have the capability to check for
'large' vehicles which have a lower speed limit, there can be a final check
of the speed before fines are issued.

I don't believe they have that capability, based on conversations with people
from TRRL.
