North Carolina Truck Speed Limit
North Carolina caps interstates at 70 and trucks run the same number — no split (N.C. Gen. Stat. § 20-141). DOT can post other divided highways up to 70 too. Off the freeway the default is 55 outside town and 35 inside city limits unless a sign says otherwise. Work zones bite: speed through a marked one and you're looking at a minimum $250 fine (G.S. 20-141(j2)) on top of the regular ticket.
