NMTA-1: Night Mobile Operations on Shoulder of Two-Lane Two-Way Roadside

This figure illustrates an example of a night mobile operation on a road with two travel lanes heading in the opposite direction. The lanes are separated by a broken yellow line. Shoulders are shown to the left and right of the roadway and are separated from the roadway by solid white lines.

At the bottom of the diagram, a sign is located to the right of the shoulder. It reads "ROAD WORK AHEAD NEXT X MILES." Following the sign, about 1/3 of the way up the diagram on the right shoulder, is a work vehicle labeled "Vehicle #2 – Work Vehicle and/or Shadow Vehicle." This vehicle is equipped with a horizontal rectangular black arrow panel with four yellow dots in each corner and a truck-mounted attenuator (labeled optional). Also shown mounted on the back of Vehicle #2 is a diamond-shaped orange sign that reads "SHOULDER WORK" in black. North of Vehicle #2, about half way up the diagram, is a shaded rectangular area in the right shoulder labeled "Work Area." Immediately following the Work Area is another work vehicle labeled "Vehicle #1 – Work Vehicle."

There are three vertical lines drawn to left of the left shoulder in parallel with the roadway. These lines indicate measured distances between the objects in the diagram. The line that begins at the point where the "ROAD WORK AHEAD" sign is set stretches to the point where Vehicle #2 is located. Instructions read "See note 5." The next vertical line stretches from the front of Vehicle #2 to the work area, and is labeled "See Note 2." The last vertical line stretches from the front edge of the work area to the back of vehicle #1 and is labeled "25 feet max."
