OP, short answer yes.
long winded explaination:
as you indicated this subject has been covered previously, so please aim your kind attention to your first thread you posted out here on the forum where you were given links to NC statutes as well as the NC AG's firearm overview.
in the NC AG's document' section III D, around pg 23 i believe, you can read there are no NC statutes covering transporting firearms, including other 'weapons' in vehicles on NC roads. However, the AG goes on to state ~ 'officer safety' is paramount and the AG indicates immediate self disclosure is good for your internal soul.
now here begins the ensuing discussion...there are some indivuals who carry their firearm on the seat, some carry a opened lockable container on the seat and close it upon encounters, there are some who carry on their immediate person w/o benefit of a CHP and then wing it during encounter(s), and finally there are those who have their CHP and provide the document along with their DL, ins, & registration. of course there are multiple options from there.
remember, if you carry it on your person w/o benefit of CHP ~which is linked to your DL number, you might have bit of tap dancing to do during your encounter w/the nice officer after they run your licence.
bottom line, your choice of how you wish to transport in your vehicle based on if you, as Dirty Harry used to say...You feel lucky, punk?
i am sure others will be along to pontificate why their vehicle carry methodology is better or worse, just don't forget, INAL and i just pointed out where to find the information.
btw what happened to your organizing get togethers?
