Accidents on Icy Roads

Tweet

I live in Alaska, and often times the roads can be icy. On a two lane road, I had just switched lanes to pass someone from the right to the left. As I was passing, his bed slid towards me and hit my truck. We were both going slightly below the speed limit, because it was icy out. However, he was the one that lost control. Who is at fault? I only have liability. Will I have to pay out of my pocket for this? He had a broken tailight along with a dent near his headlight, while I have a huge dent on my truck.
