Many states , perhaps most, DO require a higher grade of license to operate any vehicle with a GVWR greater than 26,000 pounds than the one required to operate a passenger car. Here in Texas it is a NON COMMERCIAL CLASS B if the vehicle is used for certain non commercial uses.. The regular car license is a class C. They may go by other designations in other states. In Texas an RV used for personal use is exempt from requiring a CDL, but not from the non commercial class B if the GVWR is over 26000. A lighter rig may be operated with a class C.
In order to get my class B, I had to take a written test AND a driving test in a vehicle that has a GVWR of more than 26,000. In my case I used my class A RV.
