' tour bus driver was reportedly killed last night after one of the buses in her 4-vehicle caravan flipped over on a highway in Virginia.

Officials also confirmed the driver of the bus was the only fatality -- one other person was transported to a local hospital due to injury.

Officials are investigating whether the driver died before the crash or after -- which could explain why the bus drifted off the road. Officials also tell us the roads were really wet from overnight rain. A man at the scene says the bus appears to have drifted off the road for a fairly long stretch before tipping over.

A reporter from was on scene and shot footage of the wreckage.

A rep from Dinwiddie Fire and EMS tells us the bus had been carrying Miley's concert production crew -- there were several passengers on-board.

The survivors of the wreck were able to exit the bus through the front windshield, which was busted out during the crash.

Miley's manager tell us, "It was one of our tour buses, but not Miley's. It was one of our buses that transported our lighting crew."
