Two women suffered "serious" injuries when the cars they were driving collided head-on in a rural part of Merced County, according to California Highway Patrol.
A driver on Highway 140 reported that a Chevrolet Impala was driving erratically around 5 p.m. on Monday before it turned north on Cunningham Road, according to Officer Eric Zuniga.
The Impala, which was driven by 32-year-old Crystal Smith of Fresno, made it about a mile north on Cunningham Road before striking a Ford Fusion head-on, CHP said. The Fusion was driven by Gwen Powers, 30, of Mariposa, CHP said.
Powers slowed as the other car approached, CHP said, and attempted unsuccessfully to avoid a collision.
Each woman was flown out to Modesto hospitals by helicopter, CHP said.
The crash remains under investigation, Zuniga said.
