So, Alejandro’s response is correct, but all of this seems rather tangential to the question you quote. The reason the speed limit is 55 rather than 56 or 54 is because we have a cultural preference for multiples of 5… which is also why all the other speed limits I see posted are multiples of 5. Seeing a speed limit sign that read “33” or something would cause me to do a potentially life-threatening double-take.
Huh. Some of these I can understand, but I’m really curious about the 19mph one… is there a story behind that? (If I had to guess I’d say it relates to some more global 20mph limit.)

They’re unusual but they do happen. The “19 MPH” one happens to be from the campus of my alma mater.
