I haul hazmat intermittently with an F250 and a trailer. The F250 by itself has a GVWR of 10000lbs. Under federal standards, it is not a CMV unless I have my trailer attached which is also GVWR of 10000lbs. The truck has IRP apportioned plates from Utah, our main office. My truck operates in CA. CA has a different definition of CMV than the feds or Utah. Who has jurisdiction over the definition of CMV in this instance? I have a Bit inspection coming up and they lead me to believe that they think my vehicle is a CMV all of the time. We have more than one vehicle in several states. I'm not going to pre and post trip an F250 that I take to the supermarket and doesn't have any hazmat.
