Today's blast of wintry weather had Okotoks RCMP responding to 13 motor vehicle collisions in the area.

Okotoks RCMP say most incidents involved vehicles sliding off the icy roads or towards oncoming traffic.

Many vehicles ended up in ditches along area highways as drivers attempted to avoid collisions.

One incident involved a school bus with students on board.

Police say no children were injured as a result of the collision, but a male driver was taken to the hospital as a precaution.

Road conditions deteriorated rapidly throughout the day, causing the closure of the Trans Canada Highway from Calgary to Bassano.
