The Greyhound bus carrying 35 passengers was travelling from Los Angeles to Sacramento when it crashed outside downtown Fresno on Highway 99.
CHP Officer Kirk Arnold says the bus driver was trying to avoid another crash.
"We have a Trailblazer overturned in the traffic lane. The greyhound bus hits that vehicle, veers off to the right, hits a second vehicle, travels down an embankment, and hits a large eucalyptus tree before coming to rest."
Three of the Trailblazer passengers died. So did three of the 36 people on the bus, including the driver, who’s from Sacramento. A statement from Greyhound describes the driver as a 32-year employee with a clean record. The DMV says the driver’s only ticket was for failing to register his personal vehicle.
The CHP says some of the injured are at Fresno-area hospitals. Others only had minor cuts or bruises.
Greyhound sent a relief bus to take the remaining passengers to Sacramento.
