What is a "prohibited good"?

• A. A substance that is allowed in small quantities
• B. A chemical that requires special handling
• C. A substance that cannot be transported due to extreme hazards
• D. Materials that can be transported with special permits

Answer: (C)

A "prohibited good" refers to a substance that cannot be transported due to extreme hazards it poses to safety and health. These goods are often classified as dangerous because they can cause significant harm to people, property, or the environment if not handled or contained properly. This classification facilitates regulatory compliance and ensures that high-risk materials do not enter the transportation system, thus protecting the public and the environment from potential accidents.

In contrast, items that are allowed in small quantities or those that can be transported under specific conditions, such as with special permits or special handling procedures, do not fall under the category of prohibited goods. These distinctions are crucial for maintaining safe transportation practices and adhering to relevant regulations.
