In many jurisdictions, closed bodied vehicles may have a maximum propane capacity of how many pounds, with no single container exceeding how many pounds?

• A. 60 / 30
• B. 120 / 60
• C. 30 / 15
• D. 90 / 45

Answer: (D)

Transport safety for propane in enclosed vehicles focuses on limiting both the total amount carried and the size of any single container to reduce risk in a crash or fire. The standard you’re studying allows up to 90 pounds of propane in a closed cargo vehicle, and no single container may exceed 45 pounds. That means you could carry two 45-pound containers at most. The idea behind these limits is to keep the potential energy release and gas volume manageable for emergency responders and for the vehicle’s venting and safety systems. If you need more propane, you’d adjust the setup or make additional trips while staying within these rules. Always secure cylinders upright, inspect for leaks, and follow applicable regulations.
