A truck driver recently recorded this unbelievable incident on a New York Interstate.

In the clip, a semi truck traveling on Interstate 90 loses it’s trailer, without realizing it. The trailer then breaks through the highway guardrail and rolls into a ditch on the side of the road, and the truck continues on without stopping.

Facebook user Roy Hicks, who shared the video, posted the following comment:

It’s from my dash cam & yes he did continue for quite a ways down the road before realizing he lost his trailer , what happened was the king pin apron broke the king pin & part of the plate was still attached to the fifth wheel & no it wasn’t an on ramp he had just passed me when this happened
