Pursuant to RCW 47.36.280, the Standard in MUTCD Section 3B.07, is revised to read:
Edge lines shall be used on all interstate highways, rural multilane divided highways, all principal arterials and minor arterials within urbanized areas, except when curb or sidewalk exists, and may be used on other classes of roads. A jurisdiction shall conform to these requirements at such time that it undertakes to renew or install permanent markings on new or existing roadways. The edge lines shall be white, except that the edge lines shall be yellow on the left edge of each roadway of divided streets and highways and one-way roadway in the direction of travel.
Edge line markings shall also be placed on paved rural arterials with a traveled way of20 feet or more in width and an ADT of 6,000 or greater vehicles per day.
These standards shall be in effect, as provided in this section, unless the legislative authority of the local governmental body finds that special circumstances exist affecting vehicle and pedestrian safety that warrant a site-specific variance.
