A 25-year-old man either jumped or climbed onto a moving 18-wheeler before starting to dance, authorities in Texas said.
But when the semitrailer traveling south on the Eastex Freeway passed underneath a bridge, the dancing man slammed into the overpass and was knocked off the vehicle, according to a Nov. 14 news release from the Houston Police Department. He landed on the freeway below.
First responders were called to the scene near the Tuam Street bridge at about 11:35 a.m. Thursday, Nov. 10.
The man was rushed to a local hospital, where he was later pronounced dead, according to the news release.
Authorities said they believe the man might have been recording himself as he danced atop the truck. A video shared on Facebook shows the man dancing on the semitrailer before the fatal incident.
Police questioned and released the driver of the 18-wheeler. He was unaware someone had gotten on top of his truck, authorities said.
An investigation is ongoing.
