Not quite correct. In fact there has been a lot of speculation in this
thread that misses
The UK has road classifications M (motorway), A, B, C, D and U, although
C, D and U do not appear on signs or maps (technically, they should not
exceptions are known).
None of the classifications, other than M, necessarily tell you anything
width or quality of the road (usually, they do, but it's not always the
case). Instead they
tell you (approximately) about the traffic density and are (or originally
to indicate a preference ranking of sorts. If you want to get from X to Y
you'd try to
use motorways as much as possible, where you can't use a motorway you'd use
roads, where you can't use A roads you'd use B roads. If you have local
you might, on some routes, prefer a B road or even a C road to a motorway.
I've simplified a lot. It's more complicated, and less sensible, than

Perhaps, if we reach a conclusion here, the documentation may need to be
updated to make things a little more clear.
