Which of the following is a DOT hazard class?

• A. Pesticides
• B. Batteries
• C. Electronics
• D. Explosives

Answer: (D)

DOT hazard classes name the categories of danger used to guide how materials are packaged, labeled, and shipped. Explosives are one of these named categories (Class 1) because they can detonate or release energy violently, requiring very strict handling and separation from other goods.

Pesticides, batteries, and electronics can be hazardous materials, but they aren’t a single named DOT hazard class. They fall under different classes or subcategories depending on their specific properties (for example, some pesticides or components may be regulated under toxic substances, lithium battery rules, or other classifications).

So Explosives fits the definition of a DOT hazard class, making it the correct choice.
