What is the purpose of this sign?

I have seen it on the start of motorways and last week in the new Hindhead tunnel.

Why not just put the speed limit sign up 50-60 70 etc. it would be much simpler and clearer

Umm, Balthazar, pictures don't post very well here! You'll have to do a link to a picture if you want to illustrate the question.

There is a reason; it's to do with the Road Traffic Regulation Act, as motorways are 'Special Roads'. I'll see if I can find a link about it, or some of the legal bods/coppers on here might know.

There is no national speed limit for all roads and all vehicles, so one sign covers it all.

>>>What is the point of the national speed limit sign?

Covers lots of different speeds

Single carriageway is 60mph in a car, lorry 50 mph...................1 sign = 2 different speed limits

>>>What is the point of the national speed limit sign?

Isn't it 40mph for LGVs on a single carriageway?
