Legal Question in Criminal Law in California

First you did not state which of the many California codes you are citing. Vehicle code section 22349(a) is a speeding ticket, and should not be a problem. Health and Safety code section 11357(b) has to do with the possession of less that 28 grams of marijuana. This is not considered to be a minor offense. At this time the feds are not showing any interest in minor marijuana possession. You should talk to a school counselor regarding the the requirements for maintaining a federal school grant.
