Below is the uncorrected machine-read text of this chapter, intended to provide our own search engines and external engines with highly rich, chapter-representative searchable text of each book. Because it is UNCORRECTED material, please consider the following text as a useful but insufficient proxy for the authoritative book pages.

71 3B.05 contains the following standard: “A channelizing line shall be a wide or double solid white line.” Even in these stan- dards for longitudinal lines, flexibility is given regarding the width that may be used. Paragraph 3 of Section 3B.05 contains the following stan- dard: “Other pavement markings in the channelizing island area shall be white.” Paragraph 7 of Section 3B.05 contains the following stan- dard: “For exit ramps, channelizing lines shall be placed along the sides of the neutral area adjacent to the through traffic lane and the ramp lane.” Paragraph 1 of Section 3B.08 contains the following stan- dard: “Pavement markings extended into or continued through an intersection or interchange area shall be the same color and at least the same width as the line markings they extend (see Fig- ure 3B-11).” Paragraph 1 of Section 3B.16 contains the following stan- dard: “If used, stop lines shall consist of solid white lines extend- ing across approach lanes to indicate the point at which the stop is intended or required to be made.” Paragraph 4 of Section 3B.17 contains the following stan- dard: “When crosswalk lines are used, they shall consist of solid white lines that mark the crosswalk. They shall be not less than 6 in. or greater than 24 in. in width.” Paragraph 14 of Section 3B.19 contains the following stan- dard: “Where through traffic lanes approaching an intersection become mandatory turn lanes, lane-use arrow markings (see Fig- ure 3B-21) shall be used and shall be accompanied by standard signs.” Among the areas of interest of this synthesis, the only Stan- dards found within Part 3 of the 2003 MUTCD are the following: Item E in Paragraph 1 of Section 3A.05 contains the follow- ing standard: “A dotted line shall consist of noticeably shorter line segments separated by shorter gaps than used for a broken line. The width of a dotted line shall be at least the same as the width of the line it extends.” Paragraph 3 of Section 3B.03 contains the following stan- dard: “If a two-way left-turn lane that is never operated as a reversible lane is used, the lane line pavement markings on each side of the two-way left-turn lane shall consist of a nor- mal broken yellow line and a normal solid yellow line to delin- eate the edges of a lane that can be used by traffic in either direction as part of a left-turn maneuver. These markings shall be placed with the broken line toward the two-way left-turn lane and the solid line toward the adjacent traffic lane as shown in Figure 3B-7.” Paragraph 6 of Section 3B.03 contains the following stan- dard: “If a continuous median island formed by pavement mark- ings separating travel in opposite directions is used, two sets of double solid yellow lines shall be used to form the island as shown in Figures 3B-2 and 3B-4. Other markings in the median island area shall also be yellow, except crosswalk markings which shall be white (see Section 3B.17).” Paragraphs 3 and 4 of Section 3B.04 contain the following standards: “Where crossing the lane line markings with care is permitted, the lane line markings shall consist of a normal [4 to 6 in. wide] broken white line. Where crossing the lane line mark- ings is discouraged, the lane line markings shall consist of a nor- mal [4 to 6 in. wide] solid white line.” Paragraph 1 of Section APPENDIX B Standards from Chapter 3B of the 2003 MUTCD That Are Referenced in this Synthesis
