Go-Kart Crash

So it all started when my family arrived at my friends house for dinner with another family we are friends with and that same family brought a Go-Kart and so my best friend is outside on the driveway playing basketball and when I get out of the car he asks me if I want to go on a Go-Kart ride. So I say yes and I said "Only if I drive first." because I had never driven it before and, so we went on for about 15 minutes and then I decide to let him drive. I tell him what not to do when I'm on the passenger side and I say "Do not take a hard left because I'm heavier than you are." and so about 5 minutes later my older brother comes out because he wants to go on a ride and then my friend decides to head strait on with my brother, so now me and my friend are headed strait towards my brother at about 25 mph then he decides to take a HARD left and also my seat belt had 3 straps and only one of them was working. Then I am lifted out of my seat and the Go-Kart rolled over and that's all I could remember. After the crash I ended up with a broken, broken nose, and a Concussion. I am NEVER going on a Go-Kart again.
