Hello everyone, got a quick question. Got a friend of mine soon to be retired cop. Wants to know about the legalitys about carrying a firearm in a commercial vehicle. I told him I was pretty sure that you couldnt but that I would check. I went to fmcsrs website and went through the book and couldnt find a ##### thing about carrying guns in the truck.Since there is no regulation it seems as though you can, and I figure laws change from state to state. Does anyone out there have a definitive ansewer?? Thanks for all your help.
