“The bus was about right here, at Audubon and Warren, and he saw him so he tried to speed up a little bit to keep from hitting him head on. The car hit the bus like right in the middle and drove the bus to the southbound side of Warren,” Anton said.

Police said about a dozen people were transported to local hospitals with minor injuries. The driver of the vehicle that hit the bus suffered among the most serious injuries, and was last listed in temporary-serious condition.
