On the way home from work, this evening, I heard a loud bang from behind. On the far side of the road were three cars, one stopped ahead of the other two, one flipped on its side and pointing almost backwards and one plowed into a power pole. I think that the first had stopped suddenly when he saw a police car and towtrucks ahead in his lane, catching illegally parked cars. The overturned car must have tried to veer right suddenly and flipped and spun, while the third had veered left to avoid the second. Obviously the police were on the scene immediately, and helping the driver of the overturned wagon out of the car.
