As a minor in possession even as a passenger, the vehicle does not have to be in motion. Open container laws address the alcohol being in the vehicle and ignore motion as well. This isn't something to blow off. I don't know which law you were charged with so I can't tell you. You should probably first worry about dealing with this before expungement issues come into play and you may not have to.

Ok, what penalties do I face in CA?
And, later on, how do I get it expunged?
Does it make a difference if when the officers came the vehicle was parked and had been for some time?
