Instead of coming to a complete stop and letting this group of bison clear the road, this minivan driver decided to tempt fate and inch his way past…bad idea.

The bison took issue with the encroaching vehicle and delivered a quick head butt partially ripped off the bumper and left it leaking liquid as it sped away. The woman in the background’s reaction says it all.

Bison have injured more people in Yellowstone than any other animal and are more than capable of taking it to vehicles in the park. Remember that next time you’re in a bison jam and feel the urge to push past. Learn more about Yellowstone safety HERE.
