One man died late Wednesday night in a one-vehicle crash northeast of Summit.

The name of the person involved is not being released pending notification of family members.

Preliminary crash information indicates that a 2008 Buick Lucerne was westbound on 127th Street when the driver failed to negotiate a curve. The vehicle left the roadway, went into the ditch and rolled. The 42-year-old driver, who was not wearing a seat belt, was thrown from the vehicle. He was pronounced dead at the scene.

South Dakota’s Highway Patrol is investigating the crash. All information released so far is only preliminary.
