Also if stopped in California and asked or not asked are you required to declare you have a unloaded gun locked in a gun safe and the ammo locked in another safe? I would think the cops would be required to get a warrant to look in my gun safes. I was a LEO in the early 80's in Kansas and this crap was never a concern or issue but now I want to drive through a communist country and still have the ability to protect myself.
You are not required to inform the officer of the presence of guns but if they ask, by California law, you must allow them to inspect the guns or you can be arrested :
