DOT packing groups: which number indicates the highest danger?

2 3 4 1

Correct Answer:

Explanation:

The key idea is that DOT packing groups reflect how dangerous a material is to transport: Packing Group I is the highest hazard, Packing Group II is a lower hazard, and Packing Group III is the lowest hazard. In this item, the highest danger is represented by the top level on that hazard scale. The option that corresponds to that top level is the correct choice. The other numbers map to progressively lower hazard levels (or, in some cases, avoidable distractors), so they aren’t correct.
