#36: Please, No More
The thing about signage is that it has to convey a simple message to a lot of people. Plenty of signs have to be universal, meaning that anyone can understand them regardless of the language they speak. This sign is definitely universal. It’s also terrifying. There’s no way in heck anyone is going to try and get over five people on that bridge.
No one, regardless of where they are from or what language they speak, wants to be the real-life version of that stick figure falling into oblivion. There’s nothing like universal sign design and the element of mortal fear to make people follow the rules. More signs should try this tactic.
