A single vehicle collision in Merced County on Saturday injured three Turlock residents, including a 13-year-old boy who had to be taken by air ambulance to a trauma center.

The driver of the vehicle also sustained major injuries in the collision, including a partially amputated finger, according to the California Highway Patrol.

The collision happened around 10 p.m. Saturday on northbound Highway 99, just south of Buhach Road in Atwater.

Maria Enriquez, 53, was the driver of the 1999 Chevrolet Tahoe. According to the CHP, the vehicle was traveling at 65 mph in the middle lane when Enriquez made an “unsafe turning movement.”

The vehicle spun out of control, moving in and out of the lanes before spinning onto the right shoulder, where it overturned and came to a rest on its left side.

The 13-year-old boy, who was sitting in the back seat without a seat belt on, was thrown into the cargo area of the vehicle during the crash, the CHP reported. He sustained moderate injuries and complained of pain to his back. He was taken by air ambulance to a Modesto hospital.

Enriquez suffered a partially amputated finger on her left hand. She also had complaints of pain to her neck, head, and back, the CHP reported. She was taken to a Modesto hospital by air ambulance.

The front passenger in the Tahoe, Maria Rocha, 56, sustained minor injuries and was taken by ground ambulance to Mercy Medical Center in Merced.

Enriquez and Rocha were both wearing seat belts.

The collision remains under investigation, but at this time, the CHP does not believe driving under the influence was a factor in the crash.
