Always partial to a contrast I clocked these signs on my travels. The one referring to the sat nav is one I've only started seeing in the last few years. It is very much of now and hopefully has saved a few unsuitable vehicles becoming stuck in places they were never designed to tackle in the first place. This is the first time I've been able to photograph one as I'm usually in a moving car!
A much old style of signage. I'm sure nowadays it would be up on a post rather than stuck on the side wall of the corner cottage. It is apparently a pre Worboys sign. A committee headed up by Walter Worboys in 1963 met to decide upon how traffic signage should be designed with the resulting changes being rolled out on 1st January 1965.
Formed in 1878 the CTC still exists, but underwent a name change this year. It's now Cycling UK.
