In this regard, why do street signs have numbers on them?
When you don't have numbered streets, some cities put little numbers on the signs to show what the number would be so it's easier to navigate the city.
Subsequently, question is, how are blocks numbered? Most cities and towns are laid out in a grid. Each grid (or block) is numbered. So the "600 block" is the grid numbered 600. So to your example, the full message is "On the road Phuckdizguy Drive, in the block numbered 600, a man was robbed."
In respect to this, what do different color street signs mean?
A white background indicates a regulatory sign; yellow conveys a general warning message; green shows permitted traffic movements or directional guidance; fluorescent yellow/green indicates pedestrian crossings and school zones; orange is used for warning and guidance in roadway work zones; coral is used for incident
What do black street signs mean?
Black and white: Posted regulations (i.e., speed limits) are seen on black and white road signs. Regulatory signs tell you what you can and can't do on the road. Yellow traffic signs stand for slowing down, driving with caution, or a general warning. It may be yellow, or yellow-green with black wording or symbols.
