A driver's license is not required to purchase a car in the state of Texas. A license is required in order to drive the car.
If you don't have, or do not qualify for, a state drivers license, the state also issues state identification cards. The requirement that you positively identify yourself with verifiable documentation as to who you really are still exists, but it should serve as an alternative picture-ID to the drivers license. As it is in most(all?) other states, you cannot possess BOTH a Texas drivers license and a Texas identification card at the same time - only one or the other.
If your drivers license is revoked in one state, can you get a drivers license in another state?
