Retroreflective sheeting shall be applied to the rear of each truck tractor as follows: (a) Element 1: Two strips of sheeting in alternating colors, each not less than 600 mm long, located as close as practicable to the edges of the rear fenders, mudflaps or the mudflap support brackets, to mark the width of the truck tractor. The strips shall be mounted as horizontal as practicable, in a vertical plane facing the rear, on the rear fenders, mudflap support brackets, on plates attached to the mudflap support brackets, or on the mudflaps. Strips on mudflaps shall be mounted not lower than 300 mm below the lower edge of the mudflap support bracket. If
the vehicle is certified with temporary mudflap support brackets, the strips shall be mounted on the mudflaps or on plates transferable to permanent mudflap support brackets. (b) Element 2: Two pairs of white strips of sheeting, each pair consisting of strips 300 mm long, applied as horizontally and vertically as practicable, to the right and left upper contours of the body, as close to the top of the body and as far apart as practicable. No more than 25 percent of their cumulative area may be obscured by vehicle equipment as determined in a rear orthogonal view. If one pair must be relocated to avoid obscuration by vehicle equipment, the other pair may be relocated in order to be mounted symmetrically. S5.7.2 Reflex Reflectors.
