Mom tries to ride a dirtbike but instead ends up crashing into grandma sitting in her wheelchair.
Sometimes a dirtbike can have a mind of it's own, or the driver just can't hold on to it.
One wipeout causes an even worse crash.
This dude does a back flip on his dirtbike and lands face first onto a dozer.
This guy turns right into an oncoming car and goes flying. He is lucky to have survived!
