Figure 3C-1. Object Markers and End-of-Roadway Markers

This figure illustrates 13 object and end-of-roadway markers. Three types of object markers are shown.

OM1-1, OM1-2, and OM1-3 are shown labeled as Type 1 object markers:

• OM1-1 is shown as a yellow diamond shape with nine yellow circles denoting yellow retroreflectors mounted symmetrically in three diagonal rows on the marker.
• OM1-2 is shown as a black diamond shape with nine yellow circles denoting yellow retroreflectors mounted symmetrically in three diagonal rows on the marker.
• OM1-3 is shown as an all-yellow diamond shape.

OM2-1V, OM2-2V, OM2-1H, and OM2-2H are shown labeled as Type 2 object markers:

• OM2-1V is shown as a vertical white rectangle with three yellow circles denoting yellow retroreflectors in a vertical column on the marker.
• OM2-2V is shown as a vertical all-yellow rectangle.
• OM2-1H is shown as a horizontal white rectangle with three yellow circles denoting yellow retroreflectors in a horizontal row on the marker.
• OM2-2H is shown as a horizontal all-yellow rectangle.

OM-3L, OM-3C, and OM-3R are shown labeled as Type 3 object markers:

• OM-3L is shown as a vertical rectangle with diagonal alternating black and yellow stripes. The stripes are at a 45-degree angle beginning at the upper left and slanting down to the right.
• OM-3C is shown as a vertical rectangle with diagonal alternating black and yellow stripes that form upward-pointing chevrons.
• OM-3R is shown as a vertical rectangle with diagonal alternating black and yellow stripes. The stripes are at a 45-degree angle, beginning at the upper right and slanting down to the left.

OM4-1, OM4-2, and OM4-3 are shown labeled as end-of-roadway markers:

• OM4-1 is shown as a red diamond shape with nine red circles denoting red retroreflectors mounted symmetrically in three diagonal rows on the marker.
• OM4-2 is shown as a black diamond shape with nine red circles denoting red retroreflectors, mounted symmetrically in three diagonal rows on the marker.
• OM4-3 is shown as an all-red diamond shape.
