Yep they sure do, along with my dirt bike and snowmobile. If the ambulance chasers aren't hanging around when your riding, well, then it must not be all that fun to ride in the first place.
I ride my 4 and 5 yr. olds in it daily around the property and trails and never, ever had an issue. Rhinos are great machines and in my opinion just as safe a a regular ATV.
BUT , I have rolled mine twice, without the kids in of course. I was riding to the machines maximum capabilities over some extremely large rocks. I wasn't dumb enough to stick my foot or arm out and try to stop the roll however. Wasn't hurt a bit and it only cost me one tail light lens.
