California Vehicle Code 23110 addresses the illegality of throwing
any object or substance at a vehicle in operation. According to the
code, any person who throws anything at a vehicle or occupant of a
vehicle while the vehicle is being operated on a highway is guilty of a
misdemeanor.
Code 23110 also notes that if a person intentionally attempts to
cause bodily injury to a driver or occupant of a vehicle by throwing a
rock, brick, bottle, or any other object at a moving car, it is
considered a felony. Any intention to cause bodily harm to a driver or
other vehicle may be punished by imprisonment.
