Authorities say a 32-year-old Nebraska man died when his truck rolled off the road.
The Douglas County Sheriff's office says Duane Safarik, of Ralston, died after the Wednesday night crash.
Witnesses say Safarik may have lost control of the Ford F-150 he was driving after he crossed the center lane of West Center Road.
Authorities say Safarik may have overcorrected, and his truck flipped down an embankment near 240th Street.
Safarik died later at an Omaha hospital.
Investigators are trying to determine whether speed or alcohol contributed to the crash.
