Speed limit along I-26 from NC into TN ranges from 60 to 65 in most places. As you approach TN border from NC there is a sign about trucks going 55 (weigh station?) but suddenly it must drop for cars on a 6 lane highway with hardly any exits as you pop over the hill – there sits a trooper. As you go further down where there is much more congestion and exits, the speed limit increases back up to 60 and 65. Was a pretty drive that I will never do again nor spend any money for gas or food (taxes) until I reach VA or NC from now on
