The DOT Placarding System requires a vehicle carrying more than 1001 pounds of corrosive to display which placard?

• A. Black Over White
• B. White Over Black
• C. Green
• D. Red

Answer: (B)

Corrosive materials (Class 8) are identified by a placard that has a white top half and a black bottom half. This white-over-black design makes the corrosive hazard quickly recognizable to anyone handling or responding to a scene. The rule kicks in when you’re transporting more than 1,001 pounds of corrosive, requiring the placard to be displayed on all required sides of the vehicle. The other color options don’t indicate corrosives in this context—red is typically used for flammable hazards, and green isn’t the corrosive placard color. So, the appropriate placard for a large corrosive shipment is the white-over-black design.
