It sent the driver of the van, a man in his late forties, to hospital with serious injuries Monday night. It happened just before 7 o'clock in the evening. Calgary Police say both vehicles were southbound on 44th Street southwest approaching 16th Avenue southeast in the community if Forest Lawn. Investigators say the truck had apparently just activated the lights and sirens and was attempting to pass the van.  According to police, the van's driver then tried to make a left turn in front of the fire truck which somehow sent both vehicles into the front lawns of a pair of homes just missing the structures. The lone occupant of the van was rushed to the Foothills Hospital in serious but stable condition.
