RCW 46.08.065 provides for the conspicuous marking of publicly owned vehicles used on public highways with insignia on right and left sides of the vehicles. An exception may be granted by the governing body to allow for marking plainly and conspicuously in the lower left-hand corner of the rear window with the name of the agency, the County insignia and the words “Clallam County – For Official Use Only.” This type of marking is desired for some of the Clallam County fleet.
