I had a pickup today of some bulk hazmat. It was three 300 gal totes class 8 at 7500lbs. At what weight do you have to put the ID # on the trailer? All of the weight requirements I have found for this has to due with non-bulk containers. I know I have read it somewhere but I can’t remember, dispatch doesn’t know, even called the state DOT and could not get an answer there. Thanks.
