During the time of Jim Crow this was actually a law. A black man could not shake hands with a white man. This would show that the black man was at the same social par as the white man. If this happened the black man would be lynched with no trail.
Another law during Jim Crow was that, if a white man came into the bus the black man had to move to the back. They even had signs that the blacks had to move! If you did not abide by these laws you would most likely be lynched. Also, black students didn't even get school buses! White kids, of course, did.
