A hazardous material, as defined by the Department of Transportation (DOT), is a substance that poses an unreasonable risk to safety, health, and property when transported. This definition encapsulates the critical nature of hazardous materials, which can include chemicals, gases, explosives, and radioactive materials, among others. The emphasis is on the potential danger these materials can present during transportation, which requires specific handling, packaging, and labeling to mitigate risks associated with accidents or spills.

The recognition of "unreasonable risk" indicates that the risk posed by such materials, if mishandled, can lead to serious consequences, including injury to individuals, damage to property, and environmental harm. This definition is crucial for regulatory purposes, as it drives the implementation of safety protocols and compliance measures aimed at protecting public safety.

In contrast, other options do not align with this definition. For instance, stating that a substance poses "minimal risk" or is "non-toxic and safe" directly contradicts the characteristics of hazardous materials. Additionally, a product being used in manufacturing does not necessarily classify it as hazardous unless it meets specific criteria concerning its risk during transportation.
