I don't see how they can differentiate the speed limit. Nowhere on the V5 or even the van itself does it say what the unladen weight is, which is what dictates the speed limit difference.
The key point is, is the van above or below 3.05t unladen? Below and the speed limits are the same as in a car, above and it's 50 on single carriageways and 60 on dual carriageways, the others stay the same.
Mine's definitely below 3.05t, honest Officer. Truth is I don't know but if it was completely empty, no fuel, no driver, it probably would sneak under. I can't see it ever being checked though - not exactly easy to do, unlike your gross laden weight.
