A Greyhound bus ran off Highway 99 in Tulare County on Wednesday, but it remained upright, and about half the passengers had minor injuries, authorities said.
About 8:25 a.m. the bus carrying about 30 passengers veered off the southbound lanes of Highway 99 near Traver and drove across a frontage road and into a field.
Fourteen people, including the driver, suffered injuries and were taken to area hospitals for treatment.
The crash site was between Traver and Avenue 328, near Cross Creek.
Why the bus went off the road is under investigation, but alcohol or drug use was not considered a factor, California Highway Patrol officer Steve Beal said.
The bus drove through two fences and clipped a cotton transport bin on which a “Trump for President” sign was attached.
The bus left Sacramento about 3:30 a.m. and was bound for Los Angeles. Passengers told reporters they were sleeping when the bus left the roadway.
“Everybody was screaming,” said passenger Donny Van Why of Huntington Beach.
Victoria Casillas, another passenger, said she “remembered waking up, and everybody is, like, flying all over the place.”
Passenger Bamm Byas of Los Angeles said running off the highway “felt like a roller-coaster ride, but bumpier and scarier.”
He said it appeared to him that the bus driver was eating, then collapsed, before driving off the highway. “He started getting dizzy, and the whole bus went from one lane to the other lane and ended up off the road.”
The injured passengers were taken to hospitals in Visalia, Tulare and Hanford.
Another Greyhound bus was dispatched to the scene to pick up the uninjured passengers and transport them to Los Angeles.
