Dear Mr. Hulme:
This is in response to your October 23, 2012 e-mail requesting clarification of the Hazardous
Materials Regulations (HMR; 49 CFR Parts 171-180) applicable to prohibited and
permissive placarding. Specifically, you ask whether the logos as shown in the illustrations
you supplied are prohibited under the HMR. ·
The answer is yes. As provided in§ 172.502(a), no person may affix or display on a
packaging, freight container, unit load device, motor vehicle or rail car any sign,
advertisement, slogan, or device that, by its color, design, shape or content, could be
confused with any placard prescribed by the HMR. This prohibition is intended to limit the
potential dilution of hazard warning communication provided by the appropriate hazardous
materials placards. The illustrations you provide depict the same shape (i.e., square-on-
point configuration), size (i.e., 10 inches by 10 inches), and color (i.e., orange with black
legend) as that of hazard warning placards. These logos, in the aggregate, can be confused
with a Class 1 (explosive) placard prescribed in the HMR and are therefore prohibited under
§ 172.502.
I trust this satisfies your inquiry. Please contact us if we can be of further assistance.
Sincerely,
T. Glenn Foster
Chief, Regulatory Review and Reinvention Branch
Standards and Rulemaking Division

Hi Ca olyn,

eived the following request for a formal letter of interpretation.

Subj : Interpretations of 49 CFR 172.502(a)
Hazar ous Materials Information Center,
I am s eking an interpretation of 49 CFR 127.502(a) in regards to the vinyl displayed on our company vehicles. AWP, Inc.
is a te porary traffic control company that performs our work in accordance with the provisions of the Federal Highway
Admin tration's Manual on Uniform Traffic Control Devices (MUTCD), specifically "Part 6-Temporary Traffic Control," as
well as each state's temporary traffic control provisions as prescribed in 23 CFR 655.603(b). To that effect, we advertise
our tw primary services on our pickup trucks: (1) temporary traffic control for road work, and (2) providing flaggers for
tempo ary traffic control. These are advertised on our vehicles through the use of FHWA designed signs: W20-1"Road
Work head" and W20-7 "Fiagger Symbol," respectively (reference http://mutcd.fhwa.dot.gov/ser-shs millennium.htm
for sig specifications). I have included the layout of our truck vinyl for your use as Attachment A.
It has b en brought to our attention that these decals may be confused for Class 1 (explosives) placards and is in violation
of 49 C R 172.502(a)(2). It is my argument that while they share the same background and legend colors as the explosives
placard , they are accepted by every State Department of Transportation (DOT) & the US DOT as standard warning signs,
and ha e simple, highly recognizable legends that cannot be confused with any other sign or placard. The diamond shape
is desig ated by FHWA as a standard warning sign. The orange background with black legend color scheme is designated
by FHW for temporary traffic control. The three (3) line message and symbol are designed by FHWA to be highly legible
and rec gnizable.
Further ore, if it is determined that these vinyl decals are in violation of 49 CFR 172.502(a), I would ask for interpretation
49 CFR 72.SO(a) regarding the use of FHWA designed diamond signs being required to be mounted to vehicles used as
part of obile operations, as shown as required in Attachment B (reference http://mutcd.fhwa.dot.gov/ for additional
informa ion). As these vehicle mounted warning signs share the same shape and color as the explosives placards and may
be conf sed for them. If they are not in violation of 49 CFR 172.50(a), why would the decals on our pickup trucks be in
violatio ? If they are in violation, please inform the Federal Highway Administration that they are so the entire series of
vehicle ounted signs may be changed in the next revision of the MUTCD.
I look fo ward to your interpretations. Please let me know if you have any questions or need additional information.
