What is a "tank vehicle"?

A "tank vehicle" specifically refers to a motor vehicle that is constructed or used to transport liquid hazardous materials in bulk. This definition is crucial within the context of the Department of Transportation's Hazardous Materials Regulations, as it ensures that there are clear guidelines for the safe transportation of hazardous liquids, which can pose significant risks if leaked or mishandled.

The regulations specify that tank vehicles have a specialized design and construction intended to handle the challenges presented by transporting liquids, especially those that are hazardous. This includes having appropriate containment features, materials that resist corrosion, and safety elements that minimize the risk of spills or accidents during transit.

Understanding the definition is essential for anyone involved in the transportation of hazardous materials, as it underscores the importance of compliance with safety standards and the proper categorization of vehicles used in this industry. The distinction is particularly relevant because it helps regulatory agencies, shippers, and carriers to follow the necessary operational protocols and safety measures specific to tank vehicles, thereby ensuring public safety and environmental protection.
