I passed my c+e lgv(hgv class1) test on 21/08/1996.
After the 1st September 1996 there was no longer a direct to c+e lgv test.
You had to do the c test first(which is what I class as rigid above 7.5t) Then once you had that you could do your lgv c+e(artic).
I remember I was in a hurry up to pass before it was all wasted.
Before then there was still the Hgv class 2/3 ( don't know the difference) for rigid trucks above 7.5t.
I could always drive up to 7.5t on a car licence(I think!)
You can still drive up.to 3.5t on a car licence these days( a big transit) on a car licence.
I've lost track of what's what these days, but before 1996 is a strange one to me?
The number of wheels is irrelevant unless you're BJ Mckay!
The unit/trailer combination I drive is 12 on the unit and 20 on the trailer....32 wheels, but it's still only c+e, but it would be stgo(special types general order, which means you are routed and can only go those roads)(don't know what category) if it was on the road.
Also to add fuel to the fire, the cpc regulations of 60hrs(I think)every 5 years classroom work to make you legal on UK roads has also thrown a lot in the mix.....this is why I don't drive LGVs on the road.
