Seeing 13 truck drivers parked under a bridge and blocking traffic on the highway going in both directions is definitely unusual. But, that’s exactly what fellow drivers encountered in Michigan. As if the sight wasn’t bizarre enough, the reason why they were doing it left onlookers even more stunned.

Michigan State Police Lt. Michael Shaw found himself in need of the public’s help in the wee hours of a Tuesday morning. Luckily, he’d get exactly what he needed from a group of selfless individuals. Now, the image of the 13 truck drivers is leaving many speechless.

Seeing 13 trucks in a row, lined up under an overpass on Interstate 696 in Detroit, Michigan, blocking traffic in both directions, doesn’t initially sound like something to be celebrated. But, make no mistake, it most definitely is. Those trucks were there for an incredible, selfless reason. The Michigan State Police (MSP) had called on them to do what they couldn’t: Help them save a man’s life.

After police in Detroit received a call that there was a man threatening to kill himself by jumping off an overpass above Interstate 696, several local law enforcement agencies rushed to the scene with negotiators. Then, the police came up with an unexpected plan to safeguard against the worst-case scenario, according to CBS News. The trucks created a “safety net” under the underpass.

When officers arrived on the scene, they calmly talked to the man as others took to the highway, flagging down truck drivers and organizing them into a row beneath the bridge, in order to shorten the distance that the man would fall if he were to jump, ABC News reported. Lt. Shaw said the trucks got into position, packed tightly together, “to make sure if [the man] moved anywhere in that overpass, there was a semi there.” Later, MSP Metro Detroit took to Twitter to share an image of the incredible effort.

“This photo does show the work troopers and local officers do to serve the public. But also in that photo is a man struggling with the decision to take his own life. Please remember help is available through the National Suicide Prevention Lifeline at 1-800-273-8255,” they wrote alongside the image. “You can also call a loved one, member of the clergy or 911. There are so many people that can help you make the choice to get help and live! It is our hope to never see another photo like this again,” they later added.

“We always want to make sure that people realize there are so many other options,” Lt. Shaw said of the post. And, they should see from the image that others, even complete strangers, do care. “There’s 13 truck drivers that didn’t even know this guy and were willing to slide underneath that overpass to help him,” Shaw added.
