Get the CDL handbook and study it.
You can obtain a CDL class B license at your local DMV. To obtain a CDL class B license you are required to take several tests before obtaining your license.

The class of the Commercial Drivers License , A, B or C refers to the weight of the vehicle. When a person gets a CDL, they take the General Knowledge test.
As much as your state charges... CDL requirements are federally regulated, but prices are not. All you have to do to upgrade to an "A" permit is take the combination vehicles written test and pay the fee.
The Online CDL Training website allows one to sign up to take CDL classes for A, B, and C classes in which there are 90 days to complete and there is no set pace.
Not sure what you mean, exactly. Class A is considered the "higher" classification, yes. If you have a Class A CDL, you can operate vehicles requiring that class of licence or any class below that. You could operate a vehicle requiring a Class B CDL, for example, but a driver with a Class B CDL wouldn't be permitted to operate a combination requiring a Class A CDL.
You will need a Class B CDL with tanker endorsement.

The time it takes to get your CDL Class B can vary depending on several factors, including the location, the specific requirements of the training program or school you choose, and your prior experience and knowledge. Generally, it can take anywhere from a few weeks to a few months to complete the necessary training and pass the required tests to obtain your CDL Class B license.
If it's just the power unit, with no trailer attached, they can do it with a Class B. But they must have a CDL to take that vehicle on a public roadway.
You're going to have to pay for the permit... no two ways about it. If you take the written tests, the only thing you'll have to pay for until you get an actual CDL is the permit itself, and you can take those tests at the DMV - you don't have to go to a truck driving school for that.
