This sign warns of elderly people crossing the road, and presumably means you should take caution and even slow down for them.
Even an American can recognise this one. Watch out for the school kids, then watch out for the old folks at the next sign down the road.
A red circle on a white background without a slash through the black symbol actually means “NO!” So, the sign on top tells us there are no bikes allowed! The one below enforces the meaning of “no” in the sign above. I hope that since dogs cannot read, the sign is interpreted by the dog walkers.
Now for the bit that always confused me! Since the red circle without a slash means “NO!” what then does this mean? No poop scooping? I’d hate to point out the obvious, but I think someone needs to read the standards code once again. I have explained that cultural differences mean more than just celebrating different holidays, and this is what I mean! Cultural differences requires a different logic right down to the core!
