What caused the tour bus crash near Hoover dam?
At least five people were killed when the bus turned onto its side in the middle of the road. At this time, no one knows what caused the accident. The position of the bus is typical of when a vehicle overcorrects after avoiding collision. However, another tour bus accident happened October 6, 2008 near Sacramento, CA. In that incident, the driver had either fallen asleep or was driving under the influence. We’ll have to wait to find out what actually happened.
