Felt my drivers side wheels lift, looked in the mirror, saw it. Pulled off the motorway, found a nice place to park!Soon as my trailer started leaving the ground I would have pulled right over. I'm not about to fight with wind like that.He kept on driving the first 5 flip should've been his warning sign to pull over and stop the truck, contact his dispatcher and let them know the Truck is going flip over with the high winds if he continues to drive.The truck with the camera was the straw that broke the camel's back. as he got closer the wind pressure increase from both vehicles, forcing more air over the top instead of the front and the back. I would argue that the cameraman aided in the truck in front flipping over.
