Deformable sign post

20th June 2005

Deformable posts have become very common on trunk routes recently. I found one that had been damaged in a collision, and it's instructive to see how it has fared. Obviously, not knowing anything of the nature or severity of impact, we shouldn't over-generalise from what we see here.
