Which high-pressure tank truck carries liquefied gases such as anhydrous ammonia and LPG, typically bullet-shaped and around 11,500 gallons?

• A. MC 338
• B. MC 307 / DOT 407
• C. MC 331
• D. MC 312

Answer: (C)

High‑pressure cargo tanks are designed specifically to transport liquefied gases at elevated pressures. The distinctive bullet‑shaped tank is a hallmark of these high‑pressure units, which are built to keep gases like LPG and anhydrous ammonia in liquid form under pressure. Their typical capacity is around 11,500 gallons, and they’re rated for the higher pressures needed to maintain liquefied gas state. This combination of design (high‑pressure bullet shape) and service ( LPG and anhydrous ammonia) identifies the MC 331 type. Other tank designs have different purposes and shapes: non‑pressure or low‑pressure tanker units carry flammable liquids but aren’t built for high‑pressure gas service; corrosives tanks have thicker walls and chemical‑resistant linings; cryogenic tanks (for very cold liquids) are insulated differently and handle refrigerated conditions. The high‑pressure, bullet‑shape LPG/anhydrous ammonia tank matches the described vehicle.
