OP, for accuracy the discount lasts until 12 June.
In your direction of travel, GSV(10 months) shows three advanced signs. The first is for information and comprises words alone with a colour palette indistinguishable from adjacent banners, the second contains a diagram and a distance(20yds) while the third is regulatory. The second and third are situated on the nearside of the road(with respect to your direction of travel) and are clear of trees and other paraphernalia which might obscure a motorist's view. The first one could be obscured by a tree, but not the second and certainly not the regulatory sign.
What interests me is the wording of the first sign: 'No right turn Uxbridge Road into Longfield Ave.' The PCN states 'New Broadway/Longfield Ave.'. Is the turn in New Broadway or Uxbridge?
