Well put @Denizzalbayrak. Seatbelt and securing items are so important. Firstly he was in the wrong angle and there was a bump. I believe getting stuck at that angle the vehicle should have been secures by a vehicle on top. As coming back the rear right wheel fall in the ditch and the weight of the whole vehicle was on that wheel, with the items shifting in the car gave the push on that side of the car which made it roll over. Not wearing seat belts made matters worse, somehow one survived, but it seems driver came under the Jeep. Not a good sight at all.
