Check the link; the red truck was being passed by the white one and the SUV. I believe norwaypinesavage has it exactly right. The red truck said he pulled back onto the road after avoiding the accident.
See that solid white line, that is the line separating a lane of traffic from the shoulder of the road. See the green, that is grass.
