The California Highway Patrol says a 2008 Mazda was heading south on Del Ray Avenue at Ditch Road, near Selma, at high speed just before 6 a.m. As the road curved, they say the driver lost control of the car, flipped and wound up submerged in a canal.
The driver and two passengers died at the scene, but a fourth passenger escaped with minor injuries.
The identities of the victims haven't been released, but the CHP says they're from Kingsburg.
Investigators say alcohol was involved in the crash.
