The truckers parked under the overpass in Detroit when a man was threatening to jump off the overpass in a suicide attempt. 

13 semis were alerted by police and that's when they parked under the overpass. Had the man jumped, the trucks would have prevented him from hitting the road.

The man on the overpass was talked down and taken into custody. Luckily no one was hurt.

The interstate was closed for nearly three hours.
