Which type of vehicle is most likely to carry hazardous materials?

Commercial trucks are the primary vehicles designed for the transportation of goods over long distances, which often include hazardous materials. These trucks are specifically regulated and equipped to handle such materials safely, adhering to strict guidelines set by agencies like the Department of Transportation (DOT) and the Environmental Protection Agency (EPA).

Hazardous materials can encompass a wide range of substances, including chemicals, flammable liquids, toxic agents, and others that require special handling and transportation protocols. The size and capabilities of commercial trucks make them suitable for carrying large quantities of these materials, ensuring that they have the necessary safety features, such as proper containment and labeling.

In contrast, passenger vehicles, vans, and service trucks are typically not designed for this purpose. While they may transport smaller quantities of certain materials, they do not have the necessary specifications or regulatory compliance for the transportation of hazardous materials on a larger scale like commercial trucks do.
