The Highway 120 Bypass claimed two more lives at 8:41 p.m. Saturday  when a 30-year-old male driver lost control of his 2009 Mercedes with it rolling over multiple times in the eastbound lanes just west of South Main Street. 
The driver died at the scene and a 16-year-old male passenger in the right front seat later succumbed to his injuries at San Joaquin General Hospital, the CHP said.
An 18-year-old passenger in the rear seat was the only one wearing a seat belt. He was able to exit the car and walk to the shoulder of the freeway. All three were from Tracy.
A CHP spokesman said it was determined the driver had made an unsafe turning movement and ran off the roadway, colliding with a guardrail, an electrical box and the base of a freeway informational sign.  No more than 30 seconds after the rear seat passenger climbed out of the vehicle, the Mercedes was struck broadside by a 2002 Elantra Hyundai in a secondary collision driven by a 38-year-old woman from Modesto.
The driver of the Hyundai was transported to Kaiser Hospital in Manteca with complaint of pain.  The surviving 18-year-old was transported to San Joaquin General Hospital and treated for minor injuries.
Alcohol appeared to be a factor in the collision, according to the CHP.  This is an ongoing investigation.  Anyone witnessing the collision or events leading up to the crash is asked to contact the Stockton area CHP Office at (209) 938-4800.
