THE DESIGN OF THE MAP OF THE UNITED STATES
The mark consists of a black outline of a map of the United States in the background and an abstract drawing of a black truck in the foreground with the letters "DSI" directly to the left of the truck cab in stylized blue lettering. Three parallelograms colored light gray, gray and black, all of different widths, trail behind the truck on the left side of the mark. The color white is intended to indicate background, outlining, shading or transparent areas and is not part of the mark.
