CDL · Hazardous materials

In which case must your vehicle display placards for the hazardous materials it carries?

Correct answer: Whenever the load includes Division 4.3 material, in any amount.

Answer options

  1. AWhenever the load includes Division 4.3 material, in any amount Correct
  2. BWhenever the load includes Class 8 material, in any amount
  3. COnly when at least 1,001 pounds of a Division 2.3 material are on board

Why

Materials that react dangerously with water (Division 4.3) and poison gases (Division 2.3) are on Placard Table 1, so any amount of them requires placards, with no 1,001-pound threshold. Corrosives (Class 8) are on Placard Table 2, so in non-bulk packages they require placards only once the Table 2 materials on board reach 1,001 pounds or more.
