> And then a slash in some cases means "end of" (end of no passing zone) but in other cases it means "no" (no left turn). So it essentially means both "allowed" and "not allowed", but I guess it's based on the color or orientation or something of the slash, or multiple thin slashes vs one big thick one? A black and white sign with a slash means "end of prohibition", a red sign with or without a slash means "probition" or "restriction". The issue is that a slash is already used to mean "prohibition" so there needs to be a different kind of slash to indicate the end. > I find myself very much preferring the help of "wordiness" in this case. The top priority while driving is clarity in messaging, not economy of space. What the US does, which is actually to combine symbols in many cases with text, gives both quick recognition and unambiguous information. I have to ask "What if you didn't understand the language of the state?", it seems the wordiness only works if you understand the language, and if you don't then you're kinda fucked. I wouldn't understand any signs in say Slovenia were they written in Slovenia, but with the current system it's not an issue as the signs look like what I have at home. I wouldn't deny not all the signs are intuitive, but it's a language with a grammar, and once you get it down, it becomes easy.
