(KLZA)-- Four people were injured in a single-vehicle Saturday afternoon wreck on Interstate-29 in Andrew County, Missouri.

The Missouri Highway Patrol reports a car driven by 58-year-old Karla Koontz of Mound City was southbound following another vehicle. The front vehicle brake checked the Koontz car, which avoided the car by changing lanes. However, the driver lost control and traveled off the west side of the road striking a guardrail.

Following the impact, the car returned to the roadway, then traveled off the east side of the roadway, coming to rest in the median.

Koontz was transported to Mosaic Life Care in St. Joseph with what were described as minor injuries. Passengers, 80-year-old Fern Hamm of Mound City and two juveniles, ages 13 and 14 from Branson, MO. were also transferred to the hospital with what were described as minor injuries.
