Towing a Car behind a 5th Wheel

Any state may exceed Federal Standards if they wish.
California requires a "Doubles Endorsement" on the driver's license for any resident towing two trailers. They say the only license that can have a "Doubles Endorsement" is a Class A CDL. Therefore, if you want to tow two trailers, and you are a resident of CA, you must have a Class A CDL with Doubles Endorsement.
If any state desires to do so, they can pass a law that ALL resident drivers of ANY vehicle of ANY size must have a Class A CDL and a medical certificate "For safety on the highways and byways, and For The Good Of The Children!"

I agree that any state can up the requirements, but that does not make them any safer. You as well as I have seen so called pro's behind the wheel of big rigs at are pure idiots. But making blanket statements about requirements without reference to a specific state is giving out miss information as I see it. Oh, and I do hold a class "B" CDL and medical card for my part time job.
