Many states, based on federal regulations, already require a Class A non-CDL license where the GCVW is greater than 26,000 pounds, AND the trailer being pulled is greater than 10,000 pounds. I know that is the case in Illinois. There is a specific non-CDL written test and driving test. I am not well versed in the actual CDL requirements, but I think one of the key differences is that the non-CDL does not require the physical/doctor exam. My F350 and Cyclone combination meets this requirements (F350 at 13,300 and Cyclone at 18,000). I'm also told this is based on the placard maximum, not actual weights. Although I know my actual weights are over 26,000 as well (F350 curb weight 9,660 ready to tow, Cyclone 17,500 loaded and ready to go, for a total of 27,160).
