Traffic signs are designed to convey information in a single image. I've seen signs warning of moose attacks, runaway trucks, and one in Scotland of two bent people with canes. The last, I assume, is to warn that there are elderly people about who may want to cross the road. Maybe it's more sinister than that, a sort of 'death awaits us all'.
My favorite is the one above of a question mark. We saw this one on entering Halifax, Nova Scotia. At first I thought I had imagined it, but the question marks popped up everywhere. My husband found it odd. I found it disturbing, as if I were being randomly challenged, "What is the meaning of life?" "Why are you here?" "Did you really need that second piece of bacon?"
I fretted about it for several days. Finally, I asked a chambermaid. She thought me daft, "It points towards the tourist bureau, of course."
