This sign is on the Golden Gate Bridge and purports to provide information about how and when you are able to cross the bridge if attempting to cross by any means other than motor vehicle (it looks cut off on the right, but this is the entire sign!). I use it in my class on information design as an example of very bad information design... I've been looking at it for two years and still haven't deciphered what most of it means. Have fun :)
