ATV age requirements for trails in Wyoming?

[beran34]

Me and a couple buddies of mine are planning on going to Wyoming to ride our four wheelers this summer and I was wondering if any body knew the age requirements for the trails there. I have looked every where to see how old I have to be to ride on the trails. I am guessing I have to take some kind of ATV safety class because I'm only 15. If any one knows how old I have to be let me know!

more then likely youd have to ride a 90cc quad thats how it is in NY. 16 and up to ride smaller cc quads i.e blasters and 250ex's and 18 for 400ex's and etc...
