• The material being offered or transported is a hazardous material.
• The placard represents a hazard of the hazardous material being offered or transported.

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 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 conformance with the International Maritime Dangerous Goods (IMDG) Code, or the United Nations (UN) Recommendations. These restrictions also do not apply to the display of a Biohazard marking, a Hot marking, or an identification number on a white diamond configuration in accordance with the tables or lists.
