I did a search on here and a few on google but couldn't find the answer to my specific situation. For work I drive a DOT regulated vehicle. (F350 service truck) I do not have a CDL just the required medical card. My question is it legal to transport a concealed firearm in a truck with DOT numbers. Also is it ok to cross state lines transporting a concealed firearms in the same vehicle (mainly Texas state line) Oh and yes I do have a CHL. Thanks
