A school bus and a truck crashed into each other in Beaver Falls, Pennsylvania. The good news is nobody was hurt -- because nobody was on the bus or in the truck -- not even drivers! Apparently, the parked bus began to roll down a hill which was surprising to police because the driver had engaged the parking brake. It ultimately rear-ended a parked truck, which then also began rolling down the hill alongside the bus, until the truck flipped onto its side. The bus continued on, shearing off one utility pole and hitting another before rolling to a stop a few feet from the porch of somebody's house.
