What is a sign? Here is my definition:
A sign is something that indicates something else
I believe that a sign is something that provides knowledge without itself being the knowledge. For example, imagine that you see a grocery bag full of food in the kitchen. This is a sign that one of your roommates recently bought food at the grocery store. Another example, imagine that you see a store that looks dark inside. This is a sign that the store is closed.
How does this apply to street signs? A street sign conveys knowledge in an abstract form without being the knowledge itself. For example, imagine that you see a sign that says 'detour ahead'. This sign is not the detour itself, but instead it is an indication of the detour.
