At the north end of South Grove in Highgate, North London, are no-entry
signs with text beneath reading "No Entry Except From East". In effect they
are saying that you can do a left-turn into South Grove but you can't do a
right-turn into it. There are none of the normal right-turn-banned signs at
all. Since drivers are not legally required to carry a compass or know the
direction in which they are travelling at a particular moment, I don't see
how anyone could be successfully prosecuted for doing a right turn here. I
also don't see why they didn't just mount a right-turn-banned sign.

'No right turn' is not a strict offence, whereas 'no entry' is.
However, it would be interesting to see what the traffic
order says
