I also inquired re: this "subject" one issue brought to me was first, insurance companys will not insure anything "illegal" now before you say its legal here, problem is most insurance company's are foreign based (as main office U.S. or Europe) so they can not insure anything that is "deemed illegal". Second depending on "value" of shipment "look out" premium is up there. Then depending on product your trailer may have cleaning issue's! Then if said trailer cross's border with a standard product/shipment of goods, do the "dogs" go crazy with the odor (hmm fun time with customs). I quickly said no thanks. Security question while transporting was a question, driver training with regards to product/security, policy's/procedures in the event of "issue/problems, break downs on side of road!!! To much for me.
