Yes, you can drive a car home from Copart if it is in operable condition and you have the appropriate insurance and registration. Before driving the car off the lot, you should inspect it carefully to make sure it is safe to drive and drive it home responsibly, without putting yourself or others at risk. It is also a good idea to have the car checked by a mechanic before driving it long distances, especially if you purchased it at an auction and do not know its full mechanical history.
