I was driving on the ice road on Big Lake when I thought the driver was turning right. By the time I realized he was turning left I had committed to going around him. I tried to stop but ended up sliding, so I punched the gas and went around. There was no contact, He chased me down and forced me to stop. I tried to apologize but he instantly wrapped my shirt up in his fist and started punching me with his other fist while trying to pull me out of the window. When he changed his tone and started to yank on my door handle I put the car into drive and ran through his car to escape dragging him for about 20 yards in the process. He tried to chase me down but I lost him and called the troopers.
