Tyler Campbell, who was reported missing Saturday night, was found about 2 p.m. Tuesday off Interstate 65 North in Tennessee, WHNT-TV, Huntsville, Ala., reported.
Campbell apparently fell asleep at the wheel while driving home from a church event and drove his truck off the road into a ravine. He suffered a broken leg and an injured shoulder.
The teenager was able to climb out of the ravine Tuesday. He crawled under a guard rail and flagged down a passing driver, who dialed 911.
