A Sunday afternoon accident along Highway 4, west of Dunton Road, was a head-on collision that resulted in fatal injuries to one of the drivers involved.

According to the California Highway Patrol, the call came in about 1:39 p.m. Sunday, the caller reporting a head-on traffic collision on State Route 4, in an unincorporated area of Stanislaus County; in the Oakdale fire/ambulance coverage area.

Emergency personnel arrived on scene and located a gray 2002 Nissan Maxima with major front end damage, overturned and resting on its passenger side, within the westbound lane and facing in a southwesterly direction. Responders also found a black 2016 Dodge Ram pick-up with major front end damage stopped on its wheels, on the south shoulder of the roadway, facing in an easterly direction about 50 feet east of the first vehicle.

The driver of the Nissan, identified as Sheryl R. Liv, 43, of Citrus Heights sustained major injuries and was life-flighted from the scene to Memorial Medical Center, where she succumbed to her injuries. The CHP report indicates she was wearing her seatbelt at the time of the crash. The driver of the pick-up, a 61-year-old man from Calaveras, was not injured; he also was wearing his seatbelt, said authorities.

The preliminary investigation shows that Liv was westbound on Highway 4 at about 60 miles per hour, approaching the eastbound pick-up truck, which was traveling at about 55 miles per hour. Witnesses on scene said the Nissan had been weaving over the yellow lines dividing the eastbound and westbound lanes for several miles and a driver behind the Nissan said the vehicle swerved completely into the eastbound lane just before colliding head on with the pick-up truck. Authorities said the driver of the pick-up did not have time to take evasive action.
