Unload your gun. You must carry your gun and ammunition separately while traveling through states with gun laws differing from your own state.
Place your unloaded gun in the trunk of your car. Make sure the lock on your trunk is properly functioning.
Lock your gun in a separate container if there is no trunk in your vehicle. Guns and ammunition must not be transported in your console or glove compartment.
Guns and ammunition must not be within reach of the driver or passengers in the vehicle.
Review the gun laws for each state you will be traveling through. It is in your best interest to be informed before you travel.
