U.S. authorities investigating a tour bus crash that killed four Chinese tourists in Utah said Thursday they haven’t uncovered any mechanical problems that could explain why the driver lost control of the vehicle.
The 60-year-old driver was on his first run for a new company when the bus crashed on Sept. 20, but he knew the area from trips with another agency, according to the preliminary report from the National Transportation Safety Board.
The group of older adults from China was on a seven-day tour that started in Los Angeles and was set to end in Salt Lake City.
