Gasoline is a flammable liquid

Gasoline is the textbook Class 3 flammable liquid: it has a low flash point and ignites very easily. Class 3 is red, so gasoline takes the red diamond with a flame symbol and the number 3. If a question asks the color for gasoline, red is the answer.

The UN number 1203

Alongside the red placard, gasoline carries the identification number 1203. The four-digit number identifies the specific material, while the red color and flame tell you the hazard. So a gasoline load can show a red flammable placard displaying 1203, which together say flammable liquid, specifically gasoline.

How the trick questions work

Trick questions offer tempting wrong colors, sometimes leaning on the idea that fuel must be special, or confusing gasoline with diesel. Diesel is also Class 3 and red but usually reads COMBUSTIBLE because of its higher flash point. Gasoline, with its low flash point, reads FLAMMABLE. Both are red; the wording differs.

How to lock it in

Tie gasoline to red, flame, 3, and 1203. Pair it with diesel in your study so you remember both are red Class 3 but gasoline is FLAMMABLE while diesel is usually COMBUSTIBLE. That contrast makes the color answer automatic. Verify the details in your official state CDL manual.
