post a link to the GS in nc or the federal law. check out Handgunlaw.us. . . . . . they have the most up to date database of the ever "liquid" changing laws about weapons and their carry/transport. at last update there was no law specific to commercial vehicles. if there is a law on this i would like to be able to read it and be informed.http://www.handgunlaw.us/documents/FAQ.pdf
