Two weekend accidents in Lincoln County injured several people, the Oklahoma Highway Patrol reports.

The first occurred Saturday afternoon on CR 970, just west of CR 3520, east of Sparks.

A 2018 Jeep Latitude driven by Joseph D Mayhall, 19, of Davenport, was eastbound when he lost control of the vehicle and it departed the roadway to left, striking a dirt embankment and rolling one time, the OHP said.

Mayhall was transported by Stroud EMS to Stroud Regional Medical Center, where he as admitted for treatment of neck and internal trunk injuries.

His passenger, Jacob Cullum, 19, Stroud, also was transported by Stroud EMS to Stroud Regional Medical Center, where he was treated for minor back and neck injuries.

The patrol said cause of the collision was improper action and unsafe speed. Seat belts were not in use, the OHP said.

Another accident occurred 4:29 a.m. Sunday on the Turner Turnpike, east of Wellston when a vehicle entered the turnpike from the Wellston westbound gate traveling the wrong way.

The 2015 Toyota Tacoma, driven by Bo Mallett, 19, Claremore, entered the turnpike going eastbound in the westbound lanes and struck head-on a 2007 Toyota Highlander driven by Fa Yuan, 35, Lindsay, the patrol said.

Troopers said Mallet was ejected in the crash and was taken by Air Evac to OU Medical Center and admitted in critical condition with head, internal trunk, external trunk, arm, and leg injuries.

Yuan, who was pinned 49 minutes before being extricated by the Chandler Fire Department, also was transported by Air Evac and admitted in OU Medical Center with internal trunk and arm injuries. 

Yuan had two passengers also from Lindsay, ages 68 and 62, with both going by ambulances to separate Oklahoma City hospitals for treatment.

The patrol said Mallett's condition at the time of the accident is under investigation, with cause of the crash listed as going the wrong way.

It was unknown if seat belts were in use by Mallett, but they were in use in the Highlander, the patrol noted.
