Department of Transportation Hazard Communication Overview 153 describes the Hazard Materials Regulations (HMR) of the U.S. Department of Transportation, which govern the proper marking and labeling of hazardous material in transport. Particular attention is paid to the nine hazard classes designated by the HMR, such as explosives and radioactive materials. The HMR requires that Department of Transportation diamond labels be present on various containers, packaging, and vehicles transporting hazardous materials.
