Not quite there are 2 class A licenses, tractor trailer and truck trailer. With a truck trailer you can drive any combination that isn’t a tractor trailer. Tractor, trailer allows you do drive anything as long as you have the right endoursements to accompany it.
I kinda wish I still was in the capital region as I have a class A and tow license and experience, but it’s just a lousy market up here you make no money doing that kind of work.
Also nice Pete
