Truck Driving on Interstate Dragging a Propane Tank

Occurred on November 22, 2021 / Buffalo Grove, Illinois, USA

Info from Licensor: I was on my way to a job interview around 3pm via i-90E. Suddenly, I heard a metal clanking sound coming from my left. I assumed it was a muffler dragging along the ground, but then a white blur caught my eye and to my surprise, it was a PROPANE TANK. I pulled out my phone for 10 seconds and filmed this video. Shortly after I stopped, the guy pulled over and that was the last I saw of him.
