lettering a vehicle which is required to be so identified may have permanently
affixed to its exterior a reflectorized weather resistant sign which shall be
horizontally oriented diamond the center height of which shall be two-thirds

vehicles using pressurized flammable gas other than those provided for in
either subsection (a) or subsection (b), in white letters PFG centered on a red
background.
(d) In the event any
such sign is affixed to a vehicle the color of which does not provide
significant contrast between the vehicle color and the sign, the sign shall
have a 6 mm (1/4 inch) border of the same color as the letters on the sign so
as to provide ready recognition of the sign.
(e)
(1) Each
vehicle required to be identified pursuant to Public Act No. 83-317 shall have
the required sign, label or placard affixed to either the body of the vehicle
as near as is practicable to the filling connection or directly upon the fuel
tank at the filling connection so as to be clearly legible when viewed at a
distance of 7.6 meters (25 feet) perpendicular to the vehicle upon which it is
displayed.
(2) Unless the sign,
label or placard required pursuant to subdivision (1) of this section is
located as hereinafter provided, each motor vehicle shall in addition to the
identification required pursuant to subdivision (1) have an additional sign,
label or placard affixed to the back of the vehicle, not including the bumper,
