Do these messages irritate anyone else?

They've put those overhead electronic signs up at great expense for warning people about, for instance, accidents ahead, so they feel they have to justify them by putting messages up all the time. Sigh.

The one that irritates me the most (well, amuses, in an irritated, manic sort of way) is the one that says, during Scottish downpours "Beware surface water" – as if we hadn't noticed! No mention of the intense downpouring atmospheric water. I think they're slipping up not to tell us about that as well

No, they just distract. It is worse in France - the roads leading into every town are lined with billboards for mile after mile.

No they don't. I recently sat in a meeting for an hour whilst 'ground rules' were being drawn up for the group, until someone said can't we just have one 'Act normal, be polite'. And we settled on that! Bliss.
