Gasoline is most often hauled in which kind of cargo tank?
Correct answer: An MC-306 (DOT-406) tank.
Answer options
- AAn MC-307 (DOT-407) tank
- BAn MC-306 (DOT-406) tank Correct
- CAn MC-312 (DOT-412) tank
Why
Gasoline does not need a high-pressure tank, so it usually rides in an MC-306 or its newer version, the DOT-406, both made for liquids at very low pressure (about 3 to 4 psi). MC-307/DOT-407 tanks handle chemicals at somewhat higher pressure, and MC-312/DOT-412 tanks are made for corrosives.
