The chart snapped at Ampang park Auto Week provided by Jabatan Keselamatan Jalanraya shows how bad the injury or fatal could be if you drive at certain speed. It simply means how bad you want to kill yourself with that speed under dangerous driving influence or condition. At 30km/h if a collision happens, it is just like jumping from 1st floor of a building. Well maybe not too bad.
But in 90km/h, it is like you jump from the 10th floor of a building. So please be careful while driving at higher speed as you surely cannot survive if an accident happened.
