What does the law have to do with being safe. If I need the law to keep me from hurting myself then I should not be on a wheeler. Wearing a helmet has to do with being responsible and wanting to make it back without injury. How fast I go should not dictate wether a helmet should be worn or not.
I think the law should not dictate whether or not they can make us wear helmets. It is our choice on whether we should have to wear them. Same with seatbelts in cars, but thats a different subject. It is part of lifes natural selection in my opinion. I do wear a helmet most times on an ATV because it is my choice and want to teach my kids the right way. The only time i dont is when im pulling my little yard trailer doing yard work. I think a UTV is a little different if it has a roll cage which is certified. I am safer in my UTV than in a car going down the Glenn and if I do happen to die while riding it, then oh well **** happens. Thats the choice I made, not anyone else.
