During my Christmas exams in my third year of high school, my brother drove me to school early in the morning. It had snowed the day before (which had now turned into thin layers of ice).
Anyway, at one point we get to a crossroad, red lights, so obviously we stopped and on the lane next to us, a truck stops. Lights turn green and my brother steps on it so he would get in front of the truck, the truck driver saw this and decided to slow down a bit and get on our lane just behind us, but instead of getting behind us, he gently touches the back of our car. Our car starts spinning like crazy, gets hit by another car, we flip upside down and keep sliding into a ditch that was filled with water and ice.
I had tried to brace myself by putting my feet against the back of passenger area, which was a bad idea since I ripped my articular ligaments. Because of that, I couldn’t move at all (seeing as the roof had caved in as well). My brother was shocked/stunned and in massive panic (but he was okay, apart from a whiplash) and didn’t know what to do… While I was in the ice cold water. Someone who saw it happen stopped and called an ambulance, by the time they got there, I was nearly unconscious (the guy who saw it and my brother managed to get me out of the car, thank god… But I was still freezing).
