Question:

What is the main difference between a portable tank and a cargo tank?

1. Cargo tanks are permanently attached; portable tanks are temporarily attached.

2. Cargo tanks are filled while on the vehicle; portable tanks are filled while off the vehicle.

3. Portable tanks must additionally show the owner or lessee's name on them.

4. All of the above

Answer: All of the above

Explanation
There are several key differences between cargo tanks and portable tanks, but the key facts have to do with the permanence of cargo tanks. Since they are stuck to commercial vehicles permanently, they will be filled while they are on the vehicle, and they do not need to display an owner's name separately. A portable tank can be filled on or off a vehicle, then attached, and must display the owner or lessee's name.
