I wouldn't do that unless he/she/they asks, if they search the car they will ask, at which point I would declare I have a weapon in the car. However laws and procedures vary depending on state. 2A is my right and not any of the LEOs business unless they ask if I have any weapons or contraband in the car. This is a link to the laws procedures in my state and i suggest everyone look up theirs in their state:
Traffic Stop While Carrying in Pennsylvania - U.S. LawShield.
One of the most dangerous things for a police officer is a traffic stop. But under the law if you are
carrying a firearm concealed or even openly in a car, you have no duty or requirement to announce to the police officer that you're carrying a firearm.
Being a legal firearm owner, it isn't as though I am going to shoot a cop for pulling me over.
