as to the container
does that mean, that when you are in your vehicle ( and without a CC permission slip), that you must keep it in a container and not open? i think SC is like that
Nope, OC is fine, so if it's plainly visible,
or if it's in a secured container, both are fine.
What that leaves you not able to do (without the CHP) is to keep it in the car but concealed, such as on the front seat under a jacket, or perhaps in the back seat floor out of plain sight. You start getting bogged down with specifics here, and those are the kinds of things that usually aren't settled until the trial, so you have to use some common sense.
Plain sight, secured container, or CHP should be three safe choices.
