A 1-year-old child was critically injured Thursday afternoon in a single-vehicle accident on State Highway 11, the Oklahoma Highway Patrol reported.

OHP reports said the accident occurred approximately a mile south of Avant at around 2:05 p.m. A 1995 Honda Accord driven by 20-year-old Kayley Hull of Barnsdall was northbound on the highway when it went off the right side of the road and then departed the road to the left after the driver apparently overcorrected, the OHP said. After rolling a half turn, the vehicle came to rest on its top, the report added.

The driver and an adult passenger in the car — identified as 29-year-old Stanley Hull of Bartlesville — were transported to a Tulsa hospital, where they were treated for head injuries and released. The OHP report said the 1-year-old male passenger was ejected an unknown distance and direction from vehicle. After being transported by Life Flight, the child was admitted in critical condition with a head injury at Tulsa’s St. Francis Hospital.

Although the car was equipped with seatbelts, none were in use at the time of the accident, the OHP said. Cause of the mishap was "failure to stay in a single lane," the report said. The Osage County Sheriffs Office and Skiatook Fire Department assisted highway patrol personnel at the scene, the report said.

Regarding the condition of the injured child, no update could be obtained at presstime.
