Sad news indeed, yes they can be dangerous tools if not ridden correctly, you have to read the ground and get your backside off the seat and stand on the pegs and be prepared to shift your weight around like a motorcross bike if you want to stay upright on more challenging terrain, i doubt that i would pass a atv course with the way i ride my quad, but i'm still here after 30 years of riding them on some fairly challenging terrain,
