I registered mine with the state. It is done at the license bureau. They didn't even ask for the previous registration, which I had. Snowmobiles don't require a title. You buy a sticker that is good for 3 years. Some states require sleds to be registered to ride their trails. They are supposed to be registered in Ohio to use them on lakes, including Erie. I haven't heard of anyone getting cited or denied access to Erie if the sled isn't registered but I am sure it has probably happened or could. When I registered mine, it was under $30.00 in 2014.
