Section 172.516 Visibility and display of placards.
(a) Each placard on a motor vehicle
and each placard on a rail car must be
clearly visible from the direction it
faces, except from the direction of another transport vehicle or rail car to
which the motor vehicle or rail car is
coupled. This requirement may be met
by the placards displayed on the
freight containers or portable tanks
loaded on a motor vehicle or rail car.
(b) The required placarding of the
front of a motor vehicle may be on the
front of a truck-tractor instead of or in
addition to the placarding on the front
of the cargo body to which a trucktractor is attached.
(c) Each placard on a transport vehicle, bulk packaging, freight container
or aircraft unit load device must - 
(1) Be securely attached or affixed
thereto or placed in a holder thereon.
(See appendix C to this part.);

(2) Be located clear of appurtenances
and devices such as ladders, pipes,
doors, and tarpaulins;
(3) So far as practicable, be located so
that dirt or water is not directed to it
from the wheels of the transport vehicle;
(4) Be located away from any marking (such as advertising) that could
substantially reduce its effectiveness,
and in any case at least 3 inches (76.0
mm.) away from such marking;
(5) Have the words or identification
number (when authorized) printed on it
displayed horizontally, reading from
left to right;
(6) Be maintained by the carrier in a
condition so that the format, legibility, color, and visibility of the
placard will not be substantially reduced due to damage, deterioration, or
obscurement by dirt or other matter;
(7) Be affixed to a background of contrasting color, or must have a dotted
or solid line outer border which contrasts with the background color.
(d) Recommended specifications for a
placard holder are set forth in appendix
C of this part. Except for a placard
holder similar to that contained in appendix C to this part, the means used
to attach a placard may not obscure
any part of its surface other than the
borders.
(e) A placard or placard holder may
be hinged provided the required format,
color, and legibility of the placard are
maintained.
