There are plenty of no-entry signs in Edinburgh, with plates below
them saying things like "Except for buses, cycles and taxis".

A few years ago there was mention in the paper of someone claiming
these signs were invalid. However, I have not heard more and imagine
that is because the someone has discovered their assertion is
incorrect.

There have been long-running debates in Cambridge over signs that might
say "No Entry - except for cycles", which some people think would work
well in the local context of a few roads. The Cambridge City Council
continues to insist that such signs are illegal (presumably advised by
the Cambridgeshire County Council), even though they are to be found in
Peterborough (which is a Unitary Authority). The stand-off continues,
but few Peterborough traffic planners seem to end up in jail.
