Here's what we do in MI (an "inform" state)
MSP - Proper Conduct During Encounters with Police
If you do a search on this forum, there has been a lot of discussion about what to say, when to say, how to say...etc.
Never exit a car until told to do so, gun or not. Got stopped short after getting my license. Had my weapon on me. Cop wanted to show me my defective turn signal. Told him I had my sidearm on. He said okay and just stay in car. No ticket
I have been let go for being brutally honest before. Not about carrying, but I blasted a red light one time and the officer who pulled me over asked if I knew why he stopped me. I said "yep, I blasted that red light because I am late for work and it was stupid. I understand you have to give me a ticket, I deserve it". He said "be more careful" and let me go.
Does anyone have a link to state by state laws as to disclosure during a traffic stop?
When the DOJ in WI sent you your CW they included a pamphlet that says " Concealed Weapons License Information." Under "Law Enforcement Contact" # 6 - Immediately and calmly tell the officer that you have a concealed carry license and are carrying a weapon. They also advise you as to other procedures to avoid any problems. For you WI guys read the pamphlet again.
EDIT: Awww.. Mike was just a little quicker than I was :)
This is an interactive reciprocity map, but you can click on the state and get information on that states carry laws.

I think you should always verify information from a site like this on the State and Local web site before you trust it...but its a good start.
