Answer
Hi Scott.
It is illegal to carry a gun in a commercial vehicle, period. There are no permits or exceptions. I hear guys saying they carry guns. If it got stolen, or worse, you shot someone breaking in, you could be in a world of hurt too!

Ha! Keep in mind, LEO vehicles are commercial as well, mr stephens. The officer you called out, will for sure leave his arms back at the precinct now after he heard that!
I drive a truck and some states (such as CA) I ask about various laws about the guns and each state says their own thing (I ask DOT officers/State Police officers at the scale/port of entry stations). CA has sort of a "Don't ask/Don't tell" setup, which, come to think of it, I never get asked if I have any guns when Im in my tractor (I'm owner op) but I usually DO when I'm in a regular car/pickup truck.
Also keep in mind, that although they are technically illegal because no state law (or even Federal law) can annul the Constitutional Law (as far as I'm concerned, but that is a whole dif. story), many places that are State owned (such as a rest area) put up signs saying "No firearms" and whatnot. Many scale facilities do as well, but they are usually more limited to the building itself. Interpret "premises" for yourself. Ohio has put up a footnote, however, stating "Unless otherwise authorized by law" - so, as far as I'm concerned, the Second Amendment does actually state you can keep and bear a gun.
Yes, many companies state "no guns allowed" (and the like) policies. This is not just who you work for, but who you pickup/deliver to. Many companies put up signs stating they don't allow any guns on their property. They never check unless it is a high security place or an illegal one (where they don't like things such as a camera of video recorder around, since there is not "secret" product they make, the only reason I could see as to why they don't want anything recorded would be because of something illegal going on...many places live in a spirit of fear rather than that of a sound mind) and all the ones I have been checked out at mostly are into the side compartments, engine compartments, and the cab area, and are usually looking for things much more than a simple firearm, such as drugs/explosives/people (US Customs facilities, anyway) others such as mines and whatnot, have their own things. No pets/passengers/guns/recording devices are usually the biggest "searched for" items, but not too excessively... ie.. they don't rummage through everything you have and treat you like you're a terrorist.
As far as legal info, technically, my tractor is both my place of residence AND my place of business, BOTH of which is commonly exempted from the many [i will add, illegal, because the Constitution is over state laws] of the limitations imposed to guns/gun owners. There are plenty (such as myself) who basically do live out of the truck, and it IS my place of business, especially since I own the truck myself and run my own business in, through, from, and out of it.
The most harassment I have ever had with my guns is treat me like I'm a terrorist and/or check serial numbers and see if the gun(s) are stolen.
Also, add "ports" to the Military facilities/Canada type list too, as many of them have "edge of US Soil" type setups, and US Customs Officers all over and Customs Checkpoints. Many places make you turn in even anything with a camera on it (such as your cell phone) among other things. All that stuff takes up your time, and last time I checked, I wasn't paid for any of it.
so anyway...some more info on it all.
