For many years, industry and enforcement have relied on an interpretation that appeared to say that if I had ever transported gasoline in my one compartment cargo tank, I can just leave the 1203 placard on there, even if I am transporting diesel fuel today. Well, PHMSA did a rule change a couple years ago that moved a couple words around and has issued a new interpretation. You can still use gasoline placards if you have both gasoline and diesel, even if you only have the residue of gasoline. But if all you have is diesel fuel, you have to display 1993 placards. If you have a cargo tank with just diesel, you have to use NA1993 or UN1202. If you have any questions on this issue, please feel free to contact MTA for further information or a copy of the interpretation.
