Why this is the answer

On hazmat SHIPPING PAPERS, the basic description for each hazardous material typically includes (in a required sequence): the PROPER SHIPPING NAME; the HAZARD CLASS (or division); the IDENTIFICATION NUMBER (UN or NA number, e.g., UN1203 for gasoline); and the PACKING GROUP (I, II, or III — indicating the degree of danger); plus the QUANTITY and packaging. CDL hazmat. The shipping papers must be ACCURATE and ACCESSIBLE (in the door pouch or on the seat within reach while driving). They allow emergency responders to identify exactly what's being transported. The information must match the package markings and placards. Knowing what the hazmat shipping description includes (proper shipping name, hazard class, ID number, packing group) is commonly tested.
