Standard:

01 The color of delineators shall comply with the color of edge lines stipulated in Section 3B.06.

02 A series of single delineators shall be provided on the right-hand side of freeways and expressways and on at least one side of interchange ramps, except when either Condition A or Condition B is met, as follows:

A. On tangent sections of freeways and expressways when both of the following conditions are met:
1. Raised pavement markers are used continuously on lane lines throughout all curves and on all tangents to supplement pavement markings, and

2. Roadside delineators are used to lead into all curves.

B. On sections of roadways where continuous lighting is in operation between interchanges.

Option:

03 Delineators may be provided on other classes of roads. A series of single delineators may be provided on the left-hand side of roadways.

Standard:

04 Delineators on the left-hand side of a two-way roadway shall be white (see Figure 3F-1).

Guidance:

05 A series of single delineators should be provided on the outside of curves on interchange ramps.

07 Double or vertically elongated delineators should be installed at 100-foot intervals along acceleration and deceleration lanes.

08 (DE Revision) A series of delineators should be used in accordance with Paragraph 3 of Section 3F.04 wherever guardrail or other longitudinal barriers are present along a roadway or ramp.

Option:

09 Red delineators may be used on the reverse side of any delineator where it would be viewed by a road user traveling in the wrong direction on that particular ramp or roadway.

10 Delineators of the appropriate color may be used to indicate a lane-reduction transition where either an outside or inside lane merges into an adjacent lane.

Guidance:

11 When used for lane-reduction transitions, the delineators should be installed adjacent to the lane or lanes reduced for the full length of the transition and should be so placed and spaced to show the reduction (see Figure 3B-14).

Support:

12 Delineators are not necessary for traffic moving in the direction of a wider pavement or on the side of the roadway where the alignment is not affected by the lane-reduction transition.

Guidance:

13 On a highway with continuous delineation on either or both sides, delineators should be carried through transitions.

Option:

14 On a highway with continuous delineation on either or both sides, the spacing between a series of delineators may be closer.

Standard:

15 When used on a truck escape ramp, delineators shall be red.

Guidance:

16 Red delineators should be placed on both sides of truck escape ramps. The delineators should be spaced at 50-foot intervals for a distance sufficient to identify the ramp entrance. Delineator spacing beyond the ramp entrance should be adequate for guidance according to the length and design of the escape ramp.
