[Closed] Average speed cameras

Thanks.  Some of the lorries do seem to be going a fair bit faster than 56mph, and they often speed up to around 70mph on the downhill sections of dual carriageways. In a way, the faster lorries seem to cause less stress than the 40mph Tesco lorries of yore, but I've now become one of the slower vehicles on the road!

I haven't been able to get a definitive answer on the speed limit on my Land Rover, so I've played it safe and stuck to a 50-ish mph average since the A9 cameras came into effect.  It's a 2004 Td5 90 Hard Top.  I think it's classed as a commercial, and the road tax is £240, but the law, or some people's interpretation of it, is a bit ambiguous with regard to the Land Rovers.

I’m pretty sure the A14 average cams in the expansion work don’t work

They do.
