To be honest if it's not in the same county as your insurance registration then I wouldn't worry about it. Just pay the ticket and forget about it.
In Tennessee(and most states for that matter) if it's under 15mph over or less than 75mph the citation isn't reported to the state or listed on your record. The only notable exceptions to this are if you get a reckless driving ticket and any tickets from out of state. Those are immediatley reported to the State.
I don't remember who exaclty told me this but it was from a valid source. So if your going to speed just keep it within 5-10MPH of the limit and under 75.
