I stand down. You are correct. It would seem that CA has classified any trailer over 10000lbs that is not for farmer use or a travel trailer as Commercial dispite the weight of the combination.
So let me ask you, If you are driving a 3/4 ton pickup and pulling a 12000lbs trailer, you must have a CDL "A" right? Do you maintain a CDL physical, log book, HOS? Do you have to maintain IFTA and USDot stickers? Is the pickup only considered to be a commercial vehicle when towing the trailer? So if, for instance, your wife or friend drives just the pickup, do they need a CDL? Im assuming not, but Im confused on how a vehicle can flipflop from commercial to non commercial?
