Driver (CDL) - Prohibited Placarding

No person may affix or display on a packaging, unit load device, or motor vehicle, any placard described in the HMR unless it meets the following conditions:

• The material being offered or transported is a hazardous material
• The placard represents a hazard of the hazardous material being offered or transported
• The placarding conforms to the requirements of the HMR

Additionally, any sign, advertisement, slogan (such as "Drive Safely"), or device that, by its color, design, shape, or content, could be confused with any placard prescribed in the HMR is prohibited.

These restrictions do not apply to a bulk packaging, freight container, unit load device, transport vehicle, or rail car that is placarded in accordance with the Transportation of Dangerous Goods (TDG) Regulations, the International Maritime Dangerous Goods (IMDG) Code, or the United Nations (UN) Recommendations. These restrictions also do not apply to the display of a BIOHHAZARD marking, a "HOT" marking, or an identification number on a white square-on-point configuration in accordance with the HMR.
