Which tank is shaped like a cigar and has a capacity of 4000-6000 gal?

• A. DOT 406
• B. DOT 407
• C. DOT 412
• D. MC331

Answer: (C)

Recognizing tank design by shape and capacity helps identify the designation. A cigar-shaped tank is a long cylindrical cargo tank with rounded ends, built for liquids at low to moderate pressure, and it typically falls in the 4,000 to 6,000 gallon range. That combination—elongated cylinder with rounded ends plus about 4,000–6,000 gallons—matches the DOT 412 designation (MC312). The other options have different end shapes or typical capacities and do not fit this specific profile as neatly.
