The Oklahoma Highway Patrol investigated two crashes in Tulsa involving pickup trucks early Thursday.
The first crash happened just after midnight on I-44 near Harvard. Troopers said a Chevy pickup heading west hit a wall on the side of the highway. By the time the OHP arrived, the driver had disappeared.
Two and a half hours later, the OHP responded to another crash, this one on I-244 at Memorial. Troopers said a Ford pickup was westbound when it hit a wall.
EMSA took the driver to the hospital with minor injuries.
