Federal transportation officials will investigate the crash that involved a driverless shuttle bus in Las Vegas.
The National Transportation Safety Board on Thursday said a team of four officials is expected to arrive in Las Vegas Friday.
The crash between the self-operating bus and a semi-truck happened Wednesday, less than two hours after the driverless vehicle debuted. No injuries were reported.
Police in Las Vegas have said the driver of the semi-truck was cited for illegal backing. Authorities have said one of the semi-truck’s tires tapped the front bumper of the bus.
