Don't really see there is a problem whne transporting forklift w/tanks isntalled on a flat bed trailer (or than if the driver stops & leave teh cab the local sticky fingers can walk off with them). The issue is with transporting forklift in an enclosed trailer or by rail (box car or containers, especially out of state. Ihe ICC has requaltions on them & it is a no, no with them. One just needs to check these out w/ the ICC - not teh DOT. Take a look at a bill of lading & you should find an area for ICC regulation compliance.
