Which statement is true about the 'any one class' limit for hazardous materials on a bus?

• A. It can exceed 100 pounds if total is under 500
• B. It cannot exceed 100 pounds
• C. There is no limit per class
• D. It must be exactly 100 pounds

Answer: (B)

The main idea is that hazmat on a passenger bus is limited per hazard class. For any single hazard class, you may not carry more than 100 pounds. This per-class cap means you could have up to 100 pounds of each class (for example, up to 100 pounds of flammable liquids, and up to 100 pounds of poisons, etc.) as long as you stay within that limit for each class. The reason for this rule is safety—limiting how much of a potentially dangerous material is in the vehicle helps reduce risk in a crash or spill and keeps storage manageable for passengers. So the statement that it cannot exceed 100 pounds is the correct reflection of the rule. The other options aren’t accurate because there is a per-class limit (not no limit), it isn’t a blanket total of 100 pounds across all hazmat, and you don’t have to carry exactly 100 pounds—less than 100 pounds is allowed.
