FOPA Safe Passage:
Theory vs Practice in California

I'm driving through California with firearms that are legal in my home state. Does FOPA protect me?

What FOPA Says

18 U.S.C. Section 926A^[1] provides that a person "shall be entitled to transport a firearm" through any state if the firearm is unloaded and "not readily accessible or... directly accessible from the passenger compartment," or if in the passenger compartment, is "contained in a locked container other than the glove compartment or console." The person must be traveling from a place where they may lawfully possess and carry the firearm to another such place.

FOPA is an affirmative defense, not immunity from arrest. The statute provides that a person "shall not be arrested or otherwise detained" for mere transport, but this language has been interpreted narrowly by courts in restrictive states. The traveler must prove they meet all statutory conditions.

California's Complications

California defines "locked container" in Penal Code Section 16850^[2] as "a secure container that is fully enclosed and locked by a padlock, keylock, combination lock, or similar locking device." This is consistent with FOPA's requirements. However, several California-specific issues create practical risks:

Assault weapons: Firearms that are legal in other states may be classified as "assault weapons" under Penal Code Sections 30510-30530^[3]. FOPA does not preempt state assault weapon laws. A standard AR-15 with a pistol grip and detachable magazine, legal in Arizona or Nevada, is an assault weapon in California. Transporting one through California, even locked and unloaded, risks felony charges under Penal Code Section 30600 (up to 8 years imprisonment).

Large-capacity magazines: Magazines holding more than 10 rounds are prohibited under Penal Code Section 32310 (subject to ongoing litigation in Duncan v. Bonta). FOPA's safe passage arguably does not protect prohibited accessories. An out-of-state traveler carrying standard 17-round Glock magazines could face charges even with the firearms properly locked and unloaded.

Ammunition: California requires ammunition purchases to go through a licensed vendor with a background check (Penal Code Section 30352). FOPA does not clearly address ammunition transported separately from firearms.

Practical Enforcement Risks

California law enforcement officers may not be familiar with FOPA's protections. A traffic stop that reveals firearms, even properly stored, can lead to detention while officers consult supervisors or prosecutors. The firearm may be seized pending investigation even if the traveler is ultimately not charged. Recovery of seized firearms from California DOJ custody is notoriously slow, often requiring months and legal representation.

The Second Circuit's decision in Torraco v. Port Authority, 615 F.3d 129 (2d Cir. 2010), while not binding in the Ninth Circuit, illustrates the risk: the court held that a traveler who made an unplanned stop in New York lost FOPA protection because the stop was not part of "continuous travel." Extended stops in California, such as an overnight hotel stay, could theoretically be argued to break the "traveling through" requirement.

Bottom Line

Settled: FOPA provides a federal affirmative defense for transporting legally owned firearms through California if all conditions are met. California's locked container definition is consistent with FOPA.

Unsettled: Whether FOPA preempts California assault weapon and LCM laws for travelers in transit. What constitutes an impermissible "stop" that breaks continuous travel. Whether California law enforcement must honor FOPA's "shall not be arrested" language in practice.

Do: If transiting California, ensure firearms are unloaded, locked in a container in the trunk (not passenger compartment), with ammunition stored separately. Remove or leave behind any magazines exceeding 10 rounds and any firearms that could be classified as assault weapons under California law. Do not make extended stops. Carry documentation of your origin and destination.
