Missouri has no statutory duty to inform a law enforcement officer that you are carrying a firearm. Neither the constitutional-carry statute at Mo. Rev. Stat. Section 571.030 nor the concealed carry permit statute at Mo. Rev. Stat. Section 571.101 imposes an affirmative obligation on the carrier to volunteer that information during a traffic stop, a Terry stop, or any other police encounter.
This is in contrast to states such as Michigan, North Carolina, Ohio, South Carolina, and Texas, which have express duty-to-inform statutes requiring the carrier to notify the officer upon contact.
Missouri law does require:
Honest response to direct questions. A carrier who is asked by a law enforcement officer whether he or she is armed must answer truthfully. Making a false statement to a peace officer in the course of an investigation can constitute hindering prosecution or giving a false statement under Mo. Rev. Stat. Section 575.060 and related statutes.
Production of the CCP on demand. If the officer asks for the CCP, the holder must produce it. Failure to produce the CCP on demand, by a CCP holder who is in fact carrying, can result in a citation for failure to comply with Section 571.121.
Compliance with lawful officer commands. During an investigative stop, the carrier must comply with lawful commands regarding handling of the firearm. Refusing a command to keep hands visible, to slowly produce identification, or to remain in the vehicle can escalate the encounter and may itself constitute obstruction.
Beyond these requirements, the carrier is not obligated to volunteer the presence of the firearm.
Mo. Rev. Stat. Section 571.121 requires that the Missouri Department of Revenue add a notation to the driver's license of every CCP holder, identifying the holder as a CCP holder. When the carrier presents the driver's license at a traffic stop, the officer can see the notation. This is effectively passive disclosure: the officer learns of CCP-holder status from the license itself.
The notation does not by itself authorize the officer to search the vehicle or to disarm the carrier. It does, however, typically prompt the officer to ask whether the carrier is armed at the moment.
The notation may be removed at the holder's request if the CCP is voluntarily surrendered.
Missouri firearms instructors and law enforcement liaison groups generally recommend the following practices, even though they are not legally required:
Many Missouri instructors recommend voluntary disclosure for the practical reasons above. The legal rule is no duty.
A constitutional carrier (without a CCP) has no document to produce. The driver's license has no CCP notation. If the carrier is asked by the officer whether he or she is armed, the carrier must answer truthfully.
A constitutional carrier in a vehicle benefits from Mo. Rev. Stat. Section 571.030.6, which protects vehicle carry without restriction. The carrier should disclose calmly if asked and produce identification on request, but the carrier need not volunteer the firearm presence absent direct question.
A carrier who refuses to answer a direct question about whether he or she is armed, or who refuses to produce identification on request, may be detained for further investigation. Refusing to comply with lawful commands during a Terry stop is not a separate offense in itself in Missouri, but combined with other circumstances it can be evidence of obstruction.
A carrier who is found, after the stop, to have lied about being armed may be charged with making a false statement to a peace officer or with hindering prosecution under Mo. Rev. Stat. Section 575.060 or related sections.
A CCP holder who refuses to produce the CCP on demand, when carrying, may be cited for failure to comply with Section 571.121. The citation is typically dismissed if the holder produces the CCP in court.
When the encounter is with a federal officer (FBI, U.S. Marshals, DEA, ATF, etc.) on federal business, the federal officer's authority controls. There is no federal statutory duty to inform analogous to the state-law debates, but federal officers may treat firearm presence with heightened concern, particularly on federal property.
