I saw some speculation that the picture had been Photoshopped, but evidently it's legitimate. Even more interesting is the story behind it, as I found when I tracked it down.
Police said Sabrina Trotter, 44, the driver of an Indianapolis Public Schools bus, stopped on the road to take a cell phone call from her mother. Police said the driver of a Hummer, John Northrop, 54, was going northbound and was tuning his radio when he plowed into the back of the bus.Northrop suffered minor injuries. Police ticketed Trotter for an improper stop.
No children were on the bus at the time, apparently.
