Duty to Inform States

States that require you to proactively inform (8)

• Alaska — Alaska IS a duty-to-inform state. A person carrying a concealed handgun (with or without a permit) who is contacted by a peace officer must immediately inform the officer that they are carrying a concealed handgun and allow the officer to secure it for the duration of the contact (AS 11.61.220(a)(1)). This is an affirmative, proactive duty.
• District of Columbia — The District of Columbia IS a duty-to-inform jurisdiction. A licensee who is stopped by a law enforcement officer while carrying a concealed pistol must disclose that they are carrying, present the concealed carry license and the pistol's registration certificate, identify the location of the pistol, and comply with the officer's lawful directions (D.C. Code §7-2509.04). This is an affirmative, proactive duty.
• Louisiana — Louisiana IS a duty-to-inform state. A permittee armed with a handgun — or a person carrying under permitless carry (R.S. 14:95(M)) — who is approached by a police officer in an official manner or with an identified official purpose must notify the officer that they have a weapon, submit to a pat-down, and allow the officer to temporarily disarm them (R.S. 40:1379.3(I)(2)). This is an affirmative, proactive notification duty.
• Maine — Maine requires a person carrying a concealed handgun WITHOUT a valid permit to immediately inform a law enforcement officer of that fact on first contact during an arrest, detention, or routine traffic stop (25 M.R.S. §2003-A). This proactive duty applies to permitless carriers (the common carry mode in Maine); permit holders present the permit on demand.
• Michigan — Michigan HAS a statutory duty to inform. Under MCL § 28.425f, an individual licensed to carry a concealed pistol who is carrying a concealed pistol (or a portable electro-muscular-disruption device) and who is stopped by a peace officer must IMMEDIATELY disclose to the officer that he or she is carrying a pistol concealed upon his or her person or in his or her vehicle. This is a proactive notify-on-contact duty. A first violation is a state civil infraction with a $500 fine and a 6-month CPL suspension; a subsequent violation within 3 years carries a $1,000 fine and CPL revocation. (The statute frames the immediate-disclosure duty in terms of carrying a pistol concealed under the CPL; the CPL holder must also have the license in possession and show it, with a government-issued photo ID, on a peace officer's request.)
• Nebraska — Nebraska IS a duty-to-inform state. Whenever a person who is carrying a concealed handgun is contacted by a peace officer or by emergency services personnel, the person must immediately inform the officer or personnel that they are carrying a concealed handgun (Neb. Rev. Stat. §28-1202.04). This applies to permit holders and to permitless carriers, and is an affirmative, proactive duty.
• North Carolina — North Carolina HAS a statutory duty to inform. Under N.C.G.S. § 14-415.11(a) a permittee who is carrying a concealed handgun MUST disclose to any law enforcement officer that the person holds a valid permit and is carrying a concealed handgun when approached or addressed by the officer, and MUST display both the permit and valid identification upon the officer's request. This is an affirmative, proactive notify-on-contact duty, not merely a produce-on-demand rule.
• North Dakota — North Dakota IS a duty-to-inform state. A person carrying a firearm — whether under the constitutional-carry provision or a concealed weapon license — must inform a law enforcement officer that they are in possession of a firearm on any in-person contact (N.D.C.C. 62.1-04-03.1; 62.1-04-03). This is an affirmative, proactive notification duty.

In every other jurisdiction there is no affirmative duty to volunteer that you are armed — but most still require you to present a permit or answer truthfully if an officer asks. Confirm the exact rule on each state's page.
