I drove a big rig for a while and found lots of drivers who took a no weapons approach with a big grain of salt. Personally I think it's nonsense because some of the places you go, you definitely need a weapon. To hell with the DOT. Do what's right for you though, but a good BOB would be a good place to start. Stuff it under your bunk if your tractor has storage room there or in the overhead bunk if you're not team running.
