WASHINGTON, DC — The National Transportation Safety Board is investigating a crash between a tractor-trailer and bus that happened in California on April 10 and killed 10 people and left many others injured.

It happened around 5:30 p.m. local time along Interstate 5, about 100 miles north of Sacramento, involving a FedEx Freight truck and bus carrying Southern California area high-school students.

The driver of the truck lost control and crossed the median, reportedly trying to avoid a car, according to published reports, then slammed into the bus. The crash resulted in a fire, which engulfed both vehicles.

More than 30 people were transported to area hospitals, some with severe injuries.

The crash killed the truck and bus drivers, along with five students and three chaperones, according to published reports.

In a prepared statement, a FedEx spokesperson said, “Our thoughts and prayers are with everyone involved in the tragic accident on I-5 in California. We are cooperating fully with authorities as they investigate.” 

Mark Rosekind, NTSB board member commented: “We are going to be investigating the human, the machine and the environment, and what’s critical for us, especially in highway accidents, is for us to collect perishable information, the kind of information that goes away very quickly. We are interested in anything from this accident that could have some kind of national impact.”
