Cars bumped on a snowy road

Today, snow accumulated in Michigan. Especially, snow fall in the evening was extreme, so roads were covered by snow and very slippery. When I was heading toward the swimming pool, I saw two cars bumped about 20 feet ahead of me. One car was waiting a chance to turn left; another car was to turn right to enter into a mall. Suddenly, the car turning left changed its direction and hit the car. Though it was a small accident, it reminded me importance of speeding down and avoiding from sharp handling.
