We've scoured the globe and found actual safety signs messages ranging from the blatantly obvious to the just plain odd. We're a bit better off knowing that Japan warns it's drivers of crabs crossing the road and it seems that if we ever need to find a secret nuclear bunker, the UK seems to indicate their exact location. Have you seen any odd signs in your city or during your travels? We'd love to see it, feel free to leave us a comment below.
