To find out if you are able to purchase a car in the state of Missouri without having a valid driver's license you can contact the MO Division of Motor Vehicle and Driver Licensing. They should be able to give you information on if it is possible to buy, title and register a vehicle without a state driver's license.

Even if it is possible to buy a car without a license, it might be difficult finding an auto dealer that does not require a driver's license as part of their procedures for selling a vehicle. Also, most insurance companies require a person applying for an insurance policy to have, or in a short time obtain, a driver's license.
