(AP) - Federal investigators are expected to announce the results of their yearlong probe of a California collision between a FedEx tractor-trailer and a bus carrying high school students that killed 10.
The National Transportation Safety Board is scheduled to release its conclusion about the probable cause of the crash and make safety recommendations at its meeting Tuesday.
State investigators in May faulted the FedEx driver for the head-on collision. The California Highway Patrol could not determine why the driver veered across an interstate median into oncoming traffic.
The federal safety board already released thousands of pages of records from its separate investigation.
The April 10, 2014, collision happened in Orland, about 100 miles north of Sacramento. The dead included both drivers, five students heading to a visit at Humboldt State University and three adult chaperones.
