I hope occupants are Ok..???
From picture it seems that there is curve on the road and driver lost control, most probably "speeding".
Copy pasting again.. "Guardrails Please. There is no guarantee that it will eliminate ,but for sure reduce such events. There can be many reasons for this.. driver lost control due to an animal or for that matter a human coming in front, speeding, or maybe trying to be over smart while over taking something..
Guardrails reduce or eliminate the further consequences. The car occupant might get no injury at all from initial impact or losing control but they can hurt badly or die from going in the ditch, and to be honest it happens and happened so many times. I am not sure if there were any rails. But if someone is in real high speed, even guardrails will not do anything."
