how much does H licence test cost ?

[Ron Pier]

I've read through those directive that Adrian posted a few times now, and I would agree with him on the conclusion.
Since options 2,3,and 5 are for vehicles drawing a trailer, we can discount them. So that leaves options 1 and 4. Since a carrier has springs and rubber on the rollers/wheels, it must mean 20mph. A quarry machine such as a old drag line or modern Poclain type digger that has no suspension and steel rollers would have the 5mph imposed
Also since 5mph is slower than most milk floats, I think you could be in danger of pissing off the examiner!
It's probably academic anyway, as most would probably use a more modern vehicle like a 432 or Scorpion..... Just my 10cents
