   The Department shall exempt any vehicle in which hazardous material is
   transported or any person who transports any hazardous material if
   such exemption is identical to an exemption issued by the Secretary of
   the United States Department of Transportation and may exempt any
   person who transports any hazardous material intrastate under similar
   provisions. The Department may seek exemptions pursuant to federal law
   for transportation of those quantities of hazardous materials which do
   not pose a substantial danger to the public health and safety.
