CDL Hazardous Materials Practice Test

What is the proper definition of a cargo tank?

1. A removable container for liquids

2. A bulk container permanently attached to a vehicle

3. A temporary storage tank

4. A portable fuel tank

The correct answer is: A bulk container permanently attached to a vehicle

The proper definition of a cargo tank is a bulk container that is permanently attached to a vehicle. Cargo tanks are specifically designed to transport liquids and gases, often hazardous materials, and are constructed to meet stringent safety and design standards. This permanent attachment allows the tank to be part of the vehicle's structure, enabling the safe and secure transportation of bulk liquids or gases without the need for transfer to another container during transport. Other choices refer to different types of containers that do not fit the definition of a cargo tank. For example, a removable container for liquids implies that the container can be detached from a vehicle, which does not align with the definition of a cargo tank. Similarly, a temporary storage tank or a portable fuel tank suggests a level of mobility and removal from a specific vehicle context, which is not characteristic of cargo tanks designed for long-term transport of bulk materials. Therefore, understanding the permanent nature of cargo tanks is crucial for anyone handling hazardous materials and ensuring compliance with transportation regulations.
