If the item is reversible, at least 200 square centimeters of retro reflective material must be attached to each of its reversible sides. The retro reflective material attached on each side of the item must be divided equally between the upper quadrants of the side, and the material in each quadrant must be attached as closely as possible to the shoulder area of the item.
