Standard:

01 Markings shall be yellow, white, red, blue, or purple. The colors for markings shall conform to the standard highway colors. Black in conjunction with one of the colors mentioned in the first sentence of this paragraph shall be a usable color.

02 When used, white markings for longitudinal lines shall delineate:

A. The separation of traffic flows in the same direction, or

B. The right-hand edge of the roadway.

03 When used, yellow markings for longitudinal lines shall delineate:

A. The separation of traffic traveling in opposite directions,

B. The left-hand edge of the roadways of divided highways and one-way streets or ramps, or

C. The separation of two-way left-turn lanes and reversible lanes from other lanes.

04 When used, red raised pavement markers or delineators shall delineate:

A. Truck escape ramps, or

B. One-way roadways, ramps, or travel lanes that shall not be entered or used in the direction from which the markers are visible.

05 When used, blue markings shall supplement white markings for parking spaces for persons with disabilities.

06 When used, purple markings shall supplement lane line or edge line markings for toll plaza approach lanes that are restricted to use only by vehicles with registered electronic toll collection accounts.

Option:

07 Colors used for official route shield signs (see Section 2D.11) may be used as colors of symbol markings to simulate route shields on the pavement (see Section 3B.20.)

08 Black may be used in combination with the colors mentioned in the first sentence of Paragraph 1 where a light-colored pavement does not provide sufficient contrast with the markings.

Guidance:

08A (DE Revision) Black contrast markings should be used with white edge lines, broken lines, and dotted lines along all concrete roadways (see Figures 3A-1A and 3A-1B).

08B (DE Revision) Except as provided in Paragraph 8D, the black contrast marking patterns shown in Figure 3A-1A should be used along all interstates, freeways, and expressways with concrete pavement.

08C (DE Revision) The black contrast marking patterns shown in Figure 3A-1B should be used along all conventional roadways with concrete pavement.

Option:

08D (DE Revision) The black contrast marking patterns shown in Figure 3A-1B may be used along interstates, freeways, and expressways with concrete pavement based on engineering judgment.

Support:

09 When used in combination with other colors, black is not considered a marking color, but only a contrast-enhancing system for the markings.
