What color and number placard is commonly associated with gasoline during transport?

• A. Yellow, 4
• B. Red, 3
• C. Blue, 2
• D. White, 6

Answer: (B)

Gasoline is a flammable liquid, which puts it in Hazard Class 3 for transport. Placards use a red color to signal flammable liquids, and the number 3 identifies that class. So a red placard with the number 3 uniquely indicates gasoline among the common placard combinations. The other color/number pairings correspond to different hazard classes and would not indicate gasoline.
