But for class:
0 to 18.000 lb = Class D
18.001 to 26.000 = Class C
26.001 + straight truck = Class B
So you would still need a CDL, but if it is 25k it should be Class C.
In this "right coast" people's republic, the legislature gave everyone with a class D drivers' license the privileges of non-CDL class C, or 26.000 not for hire with hydraulic brakes.
It's been years since I passed, but I think the air brake endorsement portion was a "multiple guess" written test. There were brake skills demonstrations as part of the CDL A or CDL B driving test, but I don't think that was part of just getting the endorsement.
You may also need a passenger endorsement written test depending on how many seats are installed.
