Which DOT specification has a horse shoe shaped tank?

• A. DOT 406
• B. DOT 407
• C. DOT 412
• D. MC338

Answer: (B)

The shape of a highway cargo tank is a quick clue to its DOT specification, especially for non-pressurized tanks carrying flammable liquids. A horse-shoe shaped tank is a distinctive feature of DOT 407, which is a low-pressure, non-pressurized tanker designed for flammable liquids. That curved bottom design helps with drainage and stability when unloading and during transport, and you’ll see it specifically associated with this type of tank. Other specs have different end shapes and overall geometry, so they aren’t described as a horse-shoe tank. So the horse-shoe shaped tank best aligns with the DOT 407 designation.
