A Turlock man driving on Highway 99 shortly after midnight on Sunday was struck by two bullets, the California Highway Patrol reported.
The 26-year-old man was hit in the back with one bullet and the other grazed his head, said CHP spokesman Officer Tom Olsen.
The shooting was reported at 12:13 a.m. Sunday on northbound Highway 99, near the West Main Street exit.
The CHP was dispatched to the scene and found a 2006 BMW sports utility vehicle stopped along the right shoulder.
The victim was alert and able to speak with the officers. He was rushed by ambulance to an area hospital where he underwent surgery and is in stable condition.
The 26-year-old man was the sole occupant of the vehicle. In addition to the two bullets that struck him, investigating officers found additional rounds in the vehicle.
Caltrans responded to the area to divert traffic and evidence was collected at the scene.
At this time there is no suspect information.
