Okay, here is what the Revise Code of Washington says about it: RCW 77.15.460 Loaded firearm in vehicle -- Unlawful use or possession -- Penalty. (1) A person is guilty of unlawful possession of a loaded firearm in a motor vehicle if: (a) The person carries, transports, conveys, possesses, or controls a rifle or shotgun in or on a motor vehicle; and (b) The rifle or shotgun contains shells or cartridges in the magazine or chamber, or is a muzzle-loading firearm that is loaded and capped or primed. (2) A person is guilty of unlawful use of a loaded firearm if the person negligently shoots a firearm from, across, or along the maintained portion of a public highway. (3) Unlawful possession of a loaded firearm in a motor vehicle or unlawful use of a loaded firearm is a misdemeanor. (4) This section does not apply if the person: (a) Is a law enforcement officer who is authorized to carry a firearm and is on duty within the officer's respective jurisdiction; (b) Possesses a disabled hunter's permit as provided by RCW 77.32.237 and complies with all rules of the department concerning hunting by persons with disabilities. (5) For purposes of this section, a firearm shall not be considered loaded if the detachable clip or magazine is not inserted in or attached to the firearm. But if you notice, it says "negligently shoots". Just what does that mean? Does it mean you cant shoot across a road if there are cars traveling on it, or does it mean you cant shoot across a road PERIOD?
