HGV Blind Spots

yes, just found it in Google Streetview, okay not that badly hidden but much too small to be notice, no one going to look at it, it's too small, nor even HGV;

Ed, is it that tiny little yellow sign on the lampost? Man that's rubbish!

I used to cycle through that junction pretty regularly, I've been through there twice in the last couple of weeks as well and I have never noticed that sign before. How is anyone supposed to see that - it's a tiny sign that is maybe twenty yards from where the cars stop and by the looks of it, is obscured by the traffic lights anyway until you're moving, by which time you'll be busy looking at the road ahead and checking the other drivers around you aren't doing anything foolish.
