The wheel path is the path followed by the right or left wheels of a truck or car traveling in the center of a traffic lane. It is assumed to be 3 feet from the left or right lane lines. In urban areas, where inlet block-outs or manholes are in the right- or left-hand wheel path, the pavement smoothness measurements shall be made in a location determined by the Engineer.
