In NC, you may carry on your person or concealed in the vehicle, such as under seat, between cushions, etc. You do not have to "shout out the window" as someone said. If stopped, open window a few inches, keep your hands on the steering wheel. When officer approaches, quietly tell him you are a permit holder, carrying a weapon. Then do as he instructs. He may ask you for the permit & ID, may want to hold the weapon, or may say "no problem, show me your license & registration". All depends on how he sees the situation. NC LEO's are generally very respectful of right to carry. I've disclosed 5 or 6 times that I was armed & never been asked to disarm or show permit, even when we were rear ended in a traffic accident. Other driver & I had already spoken & were directing traffic when officers arrived.
P. S. Remember no carry in banks, schools, govmt property, on premise alcohol
businesses, etc. Also, no alcohol in your blood. Very similar to VA,
as I recall.
