One person died Tuesday morning in a two-vehicle crash that occurred near Wallace.

Names of the two people involved have not yet been released pending notification of family members.

Preliminary crash information indicates that a 2019 GMC Terrain SUV was westbound on South Dakota Highway 20, near the intersection with 436th Avenue, when the vehicle crossed the centerline and collided head-on with an eastbound 2019 Kenworth Semi-tractor and trailer.

The 32-year-old female driver of the SUV was pronounced dead at the scene. Her seatbelt use is under investigation. The 33-year-old male driver of the semi-tractor trailer was not injured. He was wearing a seatbelt.

That section of Highway 20 was closed to traffic for about five hours.

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