If you're unemployed go to your workforce/unemployment office and tell them you want to become a driver. The state will pay for your CDL school, then you hire on as a trainee to your company of choice. Also, a ton of local companies will train you for free. Soda/Beer/Snack distributors will train you for your cdl while you work in the warehouses, so will LTL and a lot of the Foodservice companies.

 

Celadon
Southern Refrigerated Transport
Jim Palmer Trucking
Western Express

These provide lodging and meals plus a ticket by bus/amtrak/plane to get the their school location.
Apply to all of them at the same time then take the best or first offer; whichever suits your financial capabilities.
You will need an original birth certificate and original social security card that's not laminated.
