Figure 5C-1. Horizontal Alignment and Intersection Warning Signs and Plaques and Object Markers on Low-Volume Roads
This figure shows 27 horizontal alignment and intersection warning signs and plaques and object markers for low-volume roads.
Signs titled with a "W" are shown as yellow signs with black borders and legends.
W1-1 is shown as a diamond-shaped sign with a right-angled arrow pointing up and to the left.
W1-2 is shown as a diamond-shaped sign with an arrow curving up and to the left.
W1-3 is shown as a diamond-shaped sign with an upward-pointing arrow with a 90-degree turn to the left and then a 90-degree turn to the right, straightening to a vertical direction.
W1-4 is shown as a diamond-shaped sign with an upward-pointing arrow that slants diagonally up and to the left and then straightens to a vertical direction.
W1-5 is shown as a diamond-shaped sign with an upward-pointing arrow that curves sharply to the right, to the left, to the right, and then straightens to a vertical direction.
W1-6 is shown as a horizontal rectangular sign with a large horizontal arrow pointing to the left.
W1-7 is shown as a horizontal rectangular sign with a large horizontal double-headed arrow.
W1-8 is shown as a vertical rectangular sign with a large chevron arrow pointing to the left.
W2-1 is shown as a diamond-shaped sign with a vertical black line bisecting a horizontal black line.
W2-2 is shown as a diamond-shaped sign with a vertical black line and a horizontal black line angling to the right at a 90-degree angle from the midpoint of the vertical line.
W2-3 is shown as a diamond-shaped sign with a vertical black line and a black line angling to the right at a 45-degree angle from the midpoint of the vertical line.
W2-4 is shown as a diamond-shaped sign with a black T-shaped symbol.
W2-5 is shown as a diamond-shaped sign with a black Y-shaped symbol.
W2-6 is shown as a diamond-shaped sign with a black symbol of 3 arrows indicating a counter-clockwise direction around a roundabout.
W13-1P is shown as a square advisory speed plaque with the legend "35 MPH" on two lines, with "35" in large numerals.
Thirteen object markers grouped as four types are shown.
OM1-1, OM1-2, and OM1-3 are shown labeled as Type 1 object markers for obstructions within the roadway:
- 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 for obstructions adjacent to the roadway:
- 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 for obstructions adjacent to or within the roadway:
- 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 Type 4 object markers for end of roadway:
- 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.
