Was 12 and on a roadtrip with my parents. We've been travelling for a month and we're just one day away from home. There's a snowstorm but it doesn't seem too bad, so we just decide to drive it anyway. We kind of had a bed in the back of our car and I was sleeping because I get fiercely carsick. I'm also not wearing a seatbelt. There was a huge moving truck (uhaul) in front of us and no one else really on the highway. The road turns and it's a 2-way highway, so in the other lane is a semi truck pulling trailers of fertilizer. The driver was falling asleep at the wheel and he didn't turn; instead, he drove over the uhaul in front of us, which killed the entire family in it, and knocked it into us. I heard my mother screaming, which is what woke me from my nap, and then there was just the most horrible crunching sound. It was truly indescribable. I woke up and was crying that I couldn't breathe, but both my parents were limp on their airbags. I black out for a moment and they're both awake when I wake up, but my mother's face is torn to bits and her skull is fractured and her chin is completely gone. My father can't stand because his pelvis is shattered, and my leg is at an outwards 90-degree angle, smashed from my ankle to my knee. There's also a large car pile up and everything is on fire around us, including the back of our own car. I push my mother out of the car and I'm stuck behind a twisted seat, so I tell her to go without me. She doesn't and she eventually gets me out, but my leg is broken and she's delirious with blood loss, so we crawl through the snow on the highway. My father has to roll. Shit is exploding around us at this point and it's extremely hot. Our clothing is covered in oil and gasoline, but the snow is still falling and it's extremely slushy and wet which is probably the only reason we didn't catch on fire ourselves. There's a huge emergency response team and my mother is taken to a trauma hospital in a different city while I go off with my dad. We didn't see each other for over a week, and we all needed extensive surgeries. It was wild.
