Requirements for class A no air brakes?

You would take the General Knowledge and Combination Vehicles written tests, and conduct your road test in a combination with a Gross Combination Weight Rating of more than 26,000 lbs., in which the trailer has a Gross Vehicle Weight Rating of more than 10,000 lbs. A Ford F650 pulling an eight ton equipment trailer would be one example of such a combination.

You would have to be at least 18, in which case, on top of the "no air brakes" and "no tractor-trailers" restrictions, you'd also have an "intrastate only" restriction until you turned 21.
