According to this cite:

http://en.wikipedia.org/wiki/Speed_l..._United_States

once the 55 law was repealed in the US, the individual states set all
speed limits, including interstate highways. There is a picture in the
above cite of a posted minimum and maximum speed limit. In my limited
experience, there are laws on the books that prohibit impeding traffic.
