The two passengers are a 22-year-old from Hayward and a 31-year-old from Oakland.
No word on the driver's age, or their exact identities.
Officers say they veered off the freeway around 3a.m. Saturday, and smashed into a tree right by the Camino Pablo exit.
Investigators believe the slick roads are at least one factor.
All westbound lanes reopened at around 6:30am Saturday.
