13 trucks lines up under an overpass to prevent a man from jumping off and killing himself. Story here.

(CNN)A man stood on a freeway overpass near Detroit early Thursday, threatening to jump. So thirteen tractor-trailers lined up underneath, ready to break his fall.

Troopers closed off both directions of Interstate 696 and asked for the truckers’ help, hoping to protect the man in case he fell or jumped, said Lt. Mike Shaw of the Michigan State Police.

Asking truckers to help in such cases is not unusual, Shaw said, but “most of the time these events are (resolved) pretty fast, so we only get one semi.”
