The FMCSA regulations book does NOT discuss guns, there are no federal regulations for commercial drivers in that regard. (Went thru it chapter by chapter in a CDL-A class.) Navy, above, is correct. BTW, sooooo glad I'm out from behind the "take from the driver what we can till he/she dies" wheel now and working locally! If anybody knows a person who drives for Paul Transportation, buy the poor sap a coke or a beer...
