It’s a state by state thing.
For the ORV trail in Maumee, if you had a plated street legal vehicle you didn’t need anything else. I’m not aware of any changes to that this year, but we should check. There is a permit required if your vehicle is not plated. Other parts of Ohio have more localized requirements – for the Wayne National Forest for example.
An ORV permit AND a trail permit are required in Michigan to ride the ORV trails (yes, two stickers…).
