VIDEO: What the heck caused this jackknife?

Take a look at dash cam video of a semi truck that appears to jackknife for no reason.

The video was published by Youtube user Scott Braam on September 22, 2018. Braam captioned the video, “Jack knife, mechanical failure, no injuries.”

Braam later clarified that he was told by law enforcement that the incident was caused by driveshaft failure, but other viewers have speculated that a steer tire blowout or driver error could be to blame.
