An accident involving a Black Hawk County snowplow injured two people near Waterloo over the weekend. The accident happened at a Black Hawk County intersection south of the Waterloo city limits Saturday afternoon. Sheriff’s officials say the snowplow, driven by 48-year-old Tim Connor of La Porte City, went through a stop sign and collided with a pick-up, driven by 38-year-old Larry Hora of Traer. Hora and his 36-year-old wife, Diana, both suffered head injuries and were transported to a Waterloo hospital. Their conditions are not being released. Two children in the pickup were also taken to the hospital for observation. Deputies charged Connor with failure to yield at a stop sign. Larry Hora was charged with having no insurance. The accident is the second involving a snowplow in the area in as many days. Early Friday, a pedestrian was killed in Waterloo when she was struck by a city plow in front of an elementary school.
