A filming vehicle overturns after a semi truck appears to force it off the road in this dash cam clip. 

In the video, a vehicle attempts to pass two semi trucks on the left. They successfully pull ahead of the first semi truck, but as they pull past the second, the cabover drifts suddenly to the left. The filming motorist then swerves to avoid a collision, careens across the road, and overturns on the grassy shoulder. 

We’re not quite sure what is going on here, but it doesn’t look good. 

Please be nice to each other out on the road, and check out the clip below.
