Signs not on the freeway tend to say “Speed Limit 45” (or whatever number), while freeway signs say “Maximum Speed 70”. I remember hearing once in traffic school in California that there is a difference between a “speed limit” and a posted “maximum speed”. I don’t recall what the difference was. It was something like “you may exceed the posted speed limit if it is reasonable and prudent, but you may not exceed the maximum speed”. Or something like that.
What is the legal difference between “speed limit” and “maximum speed”?
