[quote="Neil HFC"]you'll find the chevrons tend to go missing when someone drives into them, hence its preferable they are;
1) Collapsible rather than solid steel posts set in concrete
2) There to warn people of the corner.
its also ludicrous to say they are on "just about every corner".
Seriously, travel between Withernsea and Hull. These plastic chevrons are on "just about every corner" and even on some corners that actually aren't
Complete waste of money imo. The vast majority of us are well capable of following the road round a corner without a six foot chevron to guide us round. Not saying there is never a need. Of course there is but not over to over excess.
