the camera was already set up in the right place, and damned if the pile up on the highway didn't cause a loaded semi to swerve toward the camera to avoid crashing into the parked cars and trucks, and lay over because of the ditch along Highway 84 in Lubbock County, Texas

Driving too damn fast for the fog limited visibility, reported to be as low as 40 feet.

So, the red Chevy truck was moving too damn slow to get out of the way and out of the fast lane, and the semi was moving too fast to avoid hitting everything on the road no matter what lane it was in...

but that red Chevy was blocking both lanes when it went to pull into the slow lane, directly in front of the semi that legally must drive in the slow lane.
