I was told by an attorney years ago that if there is any question about it to inform the officer.
"Officer, I just want you to know that there is a gun at so-and-so and I have no intention on using it or anything else. Now how do you want me to handle it?"
I know this will irk the stuffings out of some people but the comments about having to notify someone that we are not breaking the law is BS. We are notifying them so we won't get shot due to a misunderstanding. Sometimes I feel like there is something wrong with me as I have never been stopped just so unlike it seems most people are everyday from the posts on the Internet.
If a LEO stops you he already considers you to be a lawbreaker/criminal so this stuff about an innocent party is already out the door. It can either go downhill quickly from ther by acting like a criminal or better by cooperating and acting like the law abiding citizen that you claim you are. The time to argue your 2A rights is not beside the road during a traffic stop but later in court.
DO NOT FOLLOW THIS ADVICE!
Unless you give your CCW / LTC to the officer with your drivers license you will be in for a hell of a lot of unnecessary trouble. All FN1910 has done is informed a PO that they (you) have a weapon, not necessarily a legal weapon in their eyes, just a weapon. Most inexperience PO's will yell to their partner, "He's got a gun!" and draw on you.
Try this instead.
If you are carrying and stopped while driving ( I don't know the laws for your State or County ):
Turn off your car. Yes, pull over first.
Turn off your radio. Roll down your window. ( If you have an auto that was built before 1975 you should probably do this before you shut down the auto ).
Have your insurance ready. Do not reach for your glove box during this situation. Get it out in advance.
Pass them all ( IF YOU ARE ASKED IF YOU ARE CARRYING OR HAVE A WEAPON IN THE AUTO ) to the PO if and when they ask. That means your drivers license, your pistol permit and your insurance.
Inform them you have a CCW / LTC and are carrying LEGALLY. Stress that point.
Keep your hands at 10 and 2 on the steering wheel.
Tell them ( typically two officers one on each side of auto ) where your gun is.
Tell them you are happy to proceed however they would feel most comfortable and safely.
This is a very uncomfortable situation for ALL East Coast PO's. They are not used to real world United States 2A rights.
Be calm. Be nice. Try to be relaxed.
Tell them you are happy to proceed however they would like. Without issue.
That includes being asked to get out the the auto, frisked, hand cuffed and placed in a patrol car.
Do NOT resist. It's bull, but they are scared. You are not. You will go on your way shortly. Deal with it.
If you are not asked if you are carrying or have a weapon in the auto, but are asked to get out of the auto you MUST tell them before getting out you are carrying. You have to pass them your CCW / LTC before getting out of the auto. This is for everyone's protection.
Don't speed or drive erratically. Keep your registration up to date and don't do anything stupid while CCW and driving and you will not have an issue.
I am not a lawyer. Do as you like, but this is the training I have been given on the East Coast.
