Commercial Driver’s License (CDL) HW Practice Test

Which statement is true regarding the packing group for hazmat shipments?

If a packing group exists, it must be listed on the shipping paper. Packing group is always required regardless of material. Packing group is never listed on the shipping paper. Packing group is optional even when it exists.

Correct Answer:

If a packing group exists, it must be listed on the shipping paper.

Explanation:

Packing group indicates the level of packaging required for a hazmat shipment and is part of the information you must show on the shipping papers. It tells the carrier how intensely the material must be packaged and handled, using designations that reflect the material’s hazard level. The statement you’re looking for is that if a packing group exists for a material, it must be listed on the shipping paper. That’s the rule because the shipping papers are the official guide for carriers to know the proper packaging and handling requirements for each hazmat load. Not every material has a packing group, so it isn’t “always” required. And it isn’t optional when it does exist, nor is it never listed.
