Car appreciation... the aesthetics, the engineering, etc

Apparently:

For built-up areas and motorways, vans should follow the same speed limit as cars. But on single and dual carriageways, the speed limit is 10mph lower than the speed limit for cars.

But:

If you're driving a van with a gross vehicle weight of between 3.5t and 7.5t, the van speed limits also apply, but the vehicle should be restricted to 56mph under EU law, so the limits for dual carriageways and motorways are effectively redundant.

I'm not sure they would come with a limiter by default?
