Dear Mr. Brown:
This is in response to your April 24, 2013 email, concerning the display of placards on motor
vehicles. You asked whether the display of two-sided placard affixed on the crossbar of a
headache rack (approximately six inches behind and even in height with the cab), with one placard
visible from the front, one from the rear, would comply with the placarding requirements of the
Hazardous Materials Regulations (HMR; 49 CFR Patis 171-180 ).
The answer to your question is no. When placarding is required by§ 172.504 ofthe HMR, a
transport vehicle must be placarded "on each side and each end." The placarding scenario that you
describe in your letter does not meet the requirement in§ 172.504 for placarding on each side and
each end of a transport vehicle.
I hope this information is helpful. If you have further questions, please do not hesitate to contact
this office.
Sincerely,
!Uaff·

Subject: 172.516 Placarding
I plan to operate a Dodge Crew Cab 5500 single axle vehicle with an 11' flat bed. I have a headache rack
that is approximately 6" behind the cab and the height is even with said cab. According to regulation 172.516
paragraph (a) "each placard must be clearly visible from the direction it faces" My desire is to affix a two sided
placard(s) on the cross bar of the headache rack with one side facing forward and the other side facing the rear.
The visibility from both directions would be greatly enhanced and protection of the placard(s) from road debris,
mud, and unfortunate incidents with other vehicles would be more secure. Your consideration and hopefully
positive interpretation is greatly appreciated.
