California tour bus crash kills 1, injures 30 more

A tour bus traveling in Northern California interstate on Sunday morning lost grip of the road and crashed onto its roof, killing a 33-year-old man and injuring 30 others in the vehicle's second collision in a day, according to reports.

The incident took place at around 7.30 am about 100 miles south of the Oregon. The bus operated by a company called Yellow Arrow Lines was on its route to Pasco from Los Angeles when it went off Interstate 5.

It was the second car crash for the bus. It had struck a Denny's restaurant earlier Sunday in Red Bluff, about 50 miles south, but no one was hurt, California Highway Patrol Officer Jeff Borgen said.

Three patients were in critical condition, including one who was flown by helicopter to Mercy Medical Center in Mount Shasta with severe head injuries, hospital spokeswoman Joyce Zwanziger, according to KCRA news.

The two dozen others who were treated at hospitals had mostly minor injuries and were released.

The bus company is Yellow Arrow LLC which  is based in Othello, Washington. It has a current license and had no reported accidents in the past two years before Sunday, according to federal records.

The cause of the crashes has yet to be determined but investigators said evidence at both crash sites show that driver fatigue may have been a factor. They did not say whether drugs or alcohol may have been involved or whether any citations or charges were planned.
