Wash. Admin. Code § 468-95-205 - Raised pavement markers supplementing other markings

Pursuant to RCW 47.36.280, amend paragraph 03 of the Option in MUTCD Section 3B.13 to read:

Raised pavement markers may also be used to supplement other markings for channelizing islands or approaches to other objects. The general use of raised pavement markers along right edge lines is strongly discouraged because the markers can cause steering difficulties and make bicyclists lose control of their vehicles. Raised or recessed pavement markers may be used along right edge lines on the taper in lane transition sections, on approaches to objects, and within channelization at intersections. Raised or recessed pavement markers can only be used along right edge lines at other locations where an engineering study has determined that the markers are essential to preserving pedestrian, bicycle, and motor vehicle safety. At the initiation of the engineering study, local bicycling organizations, the regional member of the state bicycle advisory committee, or the WSDOT bicycle and pedestrian program manager shall be notified of the study for review and comment. Positioning and spacing of the markers in such cases must be determined by engineering judgment taking into consideration their effect on bicycle, pedestrian, and motor vehicle safety; and, where used, are spaced closely enough (no greater than 10 feet apart) to approximate the appearance of a solid line. Other applications of raised or recessed pavement markers along right edge lines of arterials are considered to be nonconforming with this section. Cities and counties shall remove their nonconforming raised or recessed pavement markers at the time that they prepare to resurface roadways, or earlier at their option.

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.
