Summary

California prohibits carrying loaded firearms in vehicles statewide under Penal Code 25400 and 25850. Unloaded handguns transported in private vehicles must be in a locked container or the vehicle's locked trunk; long guns must be unloaded but need not be locked.

Full Breakdown

Penal Code 25400 prohibits carrying a concealed firearm in a vehicle unless the person holds a valid CCW license or qualifies for a statutory exemption. Penal Code 25850 makes it unlawful to carry a loaded firearm in any vehicle on a public street or in a public place within an incorporated city. Under Penal Code 25610, a non-prohibited person may transport an unloaded handgun in a motor vehicle only if it is in a locked container or the locked trunk. Long guns may be transported unloaded without a locked container in most cases but cannot be loaded. These rules apply uniformly statewide and override any inconsistent local vehicle-carry ordinance under Government Code 53071.

Violations & Fines

Violations of Penal Code 25400 or 25850 are misdemeanors punishable by up to one year in county jail, with felony enhancement available for prior convictions or aggravating factors.

Frequently Asked Questions

How must I transport a handgun in my car in California?

Unloaded and stored in a locked container separate from ammunition, or in the vehicle's locked trunk. Glove compartments and utility boxes do not qualify as locked containers under Penal Code 25610.

Can a California city impose stricter vehicle carry rules?

Generally no. Government Code 53071 preempts local licensing and most carry regulation. Vehicle carry standards in Penal Code 25400, 25610, and 25850 apply uniformly statewide.
