A mock crash in Colfax was so life-like that students actually passed out.

Students were evacuated as part of the drill though no one was ever in danger.

"It's really powerful," said Colfax High School student Ben May. "It's... it's terrifying - I'm really glad they showed it to us."

The point of the exercise was to show high school students the importance of obeying traffic laws at railroad crossings.

The event; however, for some students was so life-like that two students actually passed out from the site of the mock carnage.
