Why did the Bison cross the road?

Recently I took a little trip down the Alcan Hwy. Along the way we (my brother, who was sharing driving duties, and I) saw many interesting sights.



One interesting sight was this Bison crossing the road.












He moved pretty slow and did not look both ways before crossing...













I was wondering if this happens often...












And what might happen if visibility was low...












If there were an altercation who would win...













I guess it does happen on occasion.



I'm afraid the Bison didn't win...










Neither did the Toyota...
