California Highway Patrol Sgt. Joseph Azevedo tells KNTV that the semi-truck driver took an Interstate 680 off-ramp in San Ramon too quickly around 2:30 a.m. Wednesday, and the truck's trailer flipped on its side.
The truck also spilled an estimated 40 gallons of diesel fuel, snarling traffic for hours during the morning commute.
The driver had minor injuries, and a passenger was not hurt.
It wasn't clear what will happen to the boxed turkeys that landed on the road about 40 miles east of San Francisco.
The turkeys were headed to a wholesale distributor, who was going to deliver them to a big-box retail store.
