Chapter 5E. Markings
Section 5E.01 Introduction
Support:
The purpose of markings on highways is to provide guidance and information
for road users regarding roadway conditions and restrictions.
The criteria for markings, delineators, and object markers, in general, are contained in Part 3 and in other Sections of this Manual. Criteria for markings that are specific to low-volume roads are contained in this Chapter.
Section 5E.02 Centerline Markings
Standard:
Where centerline markings are installed, no-passing zone markings
in conformance with Section
3B.02 shall also be installed.
Guidance:
Centerline markings should be used on paved low-volume roads where
engineering judgment or an engineering study indicates a need for
them.
Section 5E.03 Edge Line Markings
Support:
The purpose of edge line markings is to delineate the left or right
edge of the roadway.
Guidance:
Edge line markings should be considered for use on paved low-volume
roads based on engineering judgment or an engineering study.
Option:
Edge line markings may be placed on highways with or without centerline
markings.
Edge line markings may be placed on paved low-volume roads for roadway features such as horizontal curves, narrow bridges, pavement width transitions, curvilinear alignment, and at other locations based on engineering judgment or an engineering study.
Section 5E.04 Delineators
Support:
The purpose of delineators is to enhance driver safety where it
is desirable to call attention to a changed or changing condition
such as abrupt roadway narrowing or curvature.
Option:
Delineators may be used on low-volume roads based on engineering
judgment, such as for curves, T-intersections, and abrupt changes
in the roadway width. In addition, they may be used to mark the
location of driveways or other minor roads entering the low-volume
road.
Section 5E.05 Object Markers
Support:
The purpose of object markers is to mark obstructions located within
or adjacent to the roadway, such as bridge abutments, drainage structures,
and other physical objects.
Guidance:
The end of a low-volume road should be marked with an end-of-roadway
marker in conformance with Section
3C.04.
Option:
A Type III barricade may be used where engineering studies or judgment
indicates a need for a more visible end-of-roadway treatment (see
Section 3F.01).
Section 5E.06 Other Markings
Standard:
Other markings, such as stop lines, crosswalks, pavement legends,
barricades, channelizing devices, and islands, used on low-volume
roads shall conform with the criteria contained in this Manual.
