Most interstates in NC are posted 65 or 70 mph for all vehicles. There is an exception for companies that transport manufactured housing but they have a slew of other restrictions too due to being considered oversized loads.
You can also read the law at the NHTSA Summary of Speed Laws which I consider much more reliable than some private third party website.
No reliable in regard to Idaho. Still showing max 75 mph on the interstate and 65 oh highways. Interstates max is 80 and some highways are set at 70.
Just saying....(best is to use a state website).
