Prática CDL hazmat endorsement

At one shipper you load 2,500 pounds of a Class 8 corrosive. At the next stop you add 600 pounds of a Class 3 flammable liquid. All packages are non-bulk. Which placarding is correct?

• AA DANGEROUS placard alone covers both classes on this load.
• BOnly FLAMMABLE placards, because Class 3 is the greater hazard.
• CNo placards, because each stop loaded under 2,205 pounds.
• DCORROSIVE placards are required; DANGEROUS cannot replace them.
