Traffic jams are one of the most common excuses for being late. A bison-induced traffic jam may just sound like a lie -- but sometimes it's the truth.
The determined bison can be seen making their way across the street, causing drivers on both sides to hit their brakes.
Judging by the photo, people stayed in their vehicles, which was probably a good decision given the numbers of people who wind up injured by getting too close to the large animals.
No use in blowing your horns in these kinds of jams. The bison will let you know when you can go.
