What is the pressure range for the DOT 412 cargo tank?

• A. 10-20 psi
• B. 35-50 psi
• C. 5-10 psi
• D. 100-200 psi

Answer: (B)

DOT 412 cargo tanks are designed as low‑pressure tanks. They’re built to handle a service pressure in the mid-range of tens of psi, specifically around 35 to 50 psi. This rating supports transporting liquids that require some pressurization but not high‑pressure containment. The other ranges don’t fit this tank type: targets like 10–20 psi or 5–10 psi are too low for a low‑pressure DOT 412 design, while 100–200 psi falls into high‑pressure territory that DOT 412 tanks aren’t built for. So, 35–50 psi is the range that best matches how DOT 412 tanks are designed to operate.
