A woman captured the moment she stayed calm - as a family of bison charged towards her car.

Passenger Marisah Yazbek, 29, was on a road-trip to Montana, USA, with her friend Alina Ezzi.

The friends from California, USA were travelling through Yellowstone National Park in Wyoming when the herd of bison approached the road.

A video shows the moment panic sets in for Alina and absolute calmness for Marisah as the animals make their way across the road.

Marisah, a producer from Temecula, California, said the incident "made for a perfect look at what the friendship dynamic is like between the two."

She added: "We were on vacation, making a few stops on our scenic route to Montana.

"Once we entered Yellowstone, we immediately noted the wildlife and were in awe of the scenery.

"At first, we were comfortable seeing Bison from afar - especially if they were walking leisurely or sitting.

"But once we saw a herd of bison running towards the road we were on, we thought it best to keep a considerable distance away from them.

"The driver, Alina Ezzi, was scared of what could happen as the bison drew closer to the vehicle.

"I was thrilled that I would be able to capture footage of this event.

"The two quite opposite responses made for a perfect look at what the friendship dynamic is like between the two."

After panicking and calming down the pair laughed off the situation and carried on with their journey to Montana.

Marisah said: "We were in awe of what just happened and couldn't stop laughing.

"We kept driving but didn't get too far.

"Right after the herd of bison passed two smaller bison crossed the road to keep up with their family.

"We both thought they were so cute!"

The footage was captured on March 23.
