The sign design in the USA is weird. They really don’t like symbols, and prefer to spell things out with weird abbreviations. Instead of an obvious sign like that, you would get a diamond shaped yellow sign with saying “SPEED BUMB” and instead of a standard crosswalk sign you would get the same yellow diamond saying “PED X-ING”, and it is by no means consistent what they actually say.

The USA could really use some sign design revision.
