The incident occurred around 8:30 a.m. in the south-bound lanes between Assiniboine Avenue and Wascana Parkway, and involved two cars and a school bus. There have been no injuries reported.

The school bus was carrying 11 elementary school-age children. A second bus was sent to safely transport the kids.
