UPDATE | Megabus crashes in Ind., 18 injured

INDIANAPOLIS (AP) — A double-decker passenger bus flipped onto its side on a highway in suburban Indianapolis today after striking a crashed car, leaving 18 people with mostly minor injuries, police said.

The bus, operated by Megabus, was traveling from Atlanta to Chicago, said Sean Hughes, spokesman for the line's parent company, Coach USA North America. It was carrying 50 to 60 people when it crashed about 4:30 a.m. on Interstate 65 in Greenwood after coming upon a car that had crashed about 10 minutes earlier, state police Sgt. Shawn O'Keefe said.

"The driver apparently didn't see it because of the rain or something and swerved to avoid it," O'Keefe said. "The bus driver swerved and ended up turning the bus over on its side, and it went into the median."

The roadway was wet from overnight storms and some light rain continued in central Indiana.

A witness who had stopped to check on the crashed car told police the bus struck the rear of the car, a news release said. The collision sent the bus into the median and the car into a ditch.
