Section 3B.07 - Warrants for Use of Edge Lines

Standard:

01 (DE Revision) Edge line markings shall be placed on paved and surface-treated roadways with the following characteristics:

. Interstates,

B. Freeways,

C. Expressways, and

D. Roads with a traveled way of 20 feet or more in width and an ADT of 3,000 vehicles per day or greater.

Guidance:

02 (DE Revision) Edge line markings should be placed on paved and surface-treated roadways where an engineering study indicates a need for edge line markings.

03 Edge line markings should not be placed where an engineering study or engineering judgment indicates that providing them is likely to decrease safety.

Option:

03A (DE Revision) Edge line markings may be maintained along roadways at the intersection with minor roadways or driveways with ADTs less than 200 vehicles per day.

04 Edge line markings may be placed on streets and highways with or without center line markings.

05 Edge line markings may be excluded, based on engineering judgment, for reasons such as if the traveled way edges are delineated by curbs, parking, or other markings.

06 If a bicycle lane is marked on the outside portion of the traveled way, the edge line that would mark the outside edge of the bicycle lane may be omitted.

07 Edge line markings may be used where edge delineation is desirable to minimize unnecessary driving on paved shoulders or on refuge areas that have lesser structural pavement strength than the adjacent roadway.
