Motorway signs only lead to trouble ahead

I WAS heading southbound on the M50 one night recently when I almost missed my turn-off as the main signpost for it wasn’t visible because of overgrown trees.

In fact almost all of the signposts on the left-hand side of the road on the southern part of the M50 are partially blocked by vegetation. This is a driving hazard in itself.

What is much more sinister - and I have written to the NRA about this, with no response - is the fact that the sign indicating the exit is actually on the exit, and sometimes on the slip road itself.
