Don't confuse the requirements for having to have a CDL (26,000 pounds) with those that define a Commercial Motor Vehicle (10,001 pounds). You don't have to have a CDL for, say, an 11,000 pound vehicle, but it is a CMV nonetheless, and requires logging and scaling, and all the other wonderful benefits of being a CMV.
