Roads over here have lane markings on the road surface so you know which lane to be in approaching a junction some will have an arrow straight ahead, left or right, sometimes a road number or destination as well, these are OK in light to medium traffic but once it gets nose to tail you can't see the road surface. There are many air heads who never look at the road surface (it's beneath them to look down maybe) they are usually the ones that approach a junction in the left turn lane but go straight ahead and get all shirty and blowing their horn when they get cut up (for them what drive on the other side, instead of left, read right).
We also have quite a few signs reading "no right turn except buses" sure are some funny looking buses around here; many of them look like late model BMW, Audi or Merc, and quite a few Chelsea tractors, they can't be bothered to drive a hundred yards or so to a roundabout to do a U turn.
