Pursuant to RCW 46.44.080, Clallam County may prohibit or restrict vehicle operation or vehicle weight whenever any County road, by reason of rain, snow, climatic or other conditions, will be seriously damaged or destroyed unless the operation of vehicles thereon be prohibited or restricted or their permissible weights reduced (such periods hereafter referred to as “load sensitive periods”). The Board of County Commissioners of Clallam County, Washington, upon recommendation of the County Engineer, has deemed it advisable to place certain restrictions on various County roads during load sensitive periods to protect such roadways from extensive damage.
