i say legal. i just saw on CMT a guy and his friend drive a general lee charger followed by a hazard county sheriff's car on the interstate to tennessee (forgot the starting point). fully marked with red and blues.
to impersonate a police officer you have to take actual police action.
merely putting a police sticker on your vehicle is not impersonating a police officer.
take for instance motortrend. they were completely legal in test driving the "dodge city" police charger all over hollywood, ca. this vehicle had numerous stickers with "police" on it and also a light bar and strobes.

now, if they pulled someone over with it, they are then breaking the law.
i guess it is possible that WA state has some really strict laws but with out actually seeing the code myself i'd risk it.
think about all the fraternal order of POLICE stickers that would be illegal and all those reflective state farm insurance stickers that would be illegal.
