I think that's an American sign. The context of the article is the UK. We don't that exact sign in the UK. I think there is a 'stop in 100 yards' sign but I can't recall ever seeing one. But the point was people aren't paying attention to the signs... so another sign doesn't solve that.
MUTCD == the (American) Manual on Uniform Traffic Control Devices, it was intended to demonstrate what I was talking about.
If you add multiple (large) signs ahead of the actual control device, you'll have higher compliance, since the unusual sign doesn't appear out of the blue.
Maybe in NA. In the UK the likely solution would be to install a roundabout. You can’t ignore an upcoming obstacle, in which you’re forced to give way.
Gotta say, as a biker, I love roundabouts for that reason- and people who don't ignore the obstacle go flying [1]. As a driver, I love the idea of drifting around one sometime when I have the skill and there's legitimately nobody nearby. Also forces people to focus, which is nice.
