South Dakota Highway Patrol troopers are investigating a crash on Interstate 90, just west of Sioux Falls.
Authorities say a Chevy Malibu with a flat tire was stopped in the eastbound driving lane of I-90 when it was hit by another car. The Malibu was pushed into the ditch. The other vehicle, a Pontiac Bonneville, went into the median.
The driver of the Malibu was outside the car at the time of the crash, was injured and taken to a hospital. The driver of the Bonneville was also injured and taken to the hospital.
There's no word, however, on how serious their injuries are.
