You intend to transport incompatible\nexplosives separated in this manner.\nThe answer is yes. A dromedary unit that is attached to the cab of a tractor trailer unit where\nincompatible explosives are transported with one group in the dromedary unit and one group on the\ntrailer is acceptable for hazardous materials that may not be transported on the same transport vehicle.\nI hope this information is helpful.\nSincerely,\nRehen Hillis,\nDelmer F.
