Where can I rent a class a truck in Tennessee for CDL test?

Let me clarify what I wrote earlier. The truck school had someone take the truck to a testing site. They also had students there as well. I just paid them to set up my appointment date (after I paid the State for the initial appointment) and use they’re truck to test with. I still had to do a Pre trip, Skills, and Road test. And for an hourly fee the school let me train in they’re trucks before testing. I cant see why most schools wont help you in that way, easy money for them. However I first had to pass the written test for my green card before they could help me. And you'll need your med card. Good luck.
