Which of the following options correctly states the capacity of the DOT 407 cargo tank?

• A. 1000-2000 gallons
• B. 1500-2500 gallons
• C. 2500-4000 gallons
• D. 2000-7000 gallons

Answer: (D)

DOT 407 cargo tanks are non-pressurized liquid carriers built in a variety of sizes. They don’t come in a single fixed capacity; you’ll find both smaller and much larger tanks within this class. The best choice is the option that describes a broad capacity range because it reflects the real-world variability of DOT 407 tanks—from the smaller units to the larger ones within the same family. The other options propose narrower ranges that don’t capture the typical spread of capacities for these tanks, so they don’t describe how DOT 407 tanks are actually built and used.
