Are ATV's street legal in Michigan?

Answer 1

Three and four-wheel all-terrain vehicles (ATV) cannot be upgraded for on-road use. ATV's are manufactured with a live axle, rather than a differential gear, which seriously affects their handling characteristics when operated on paved surfaces. So there is no possible way they can be street legal unless the manufacture make a ATV with a differential gear.

--The above statement is wrong. Many atvs currently sold come with open differentials, which allow the rear tires turn at different speeds (just like every unmodified truck on the road). Atvs have been street legal in many states for years. In Ohio you are allowed to ride on secondary roads without any modifications, unless a specific jurisdiction states otherwise. MI has an extensive off-highway-vehicle trail system which incorporates the use of many public roads. I imagine the rules are similar to OH (no state routes, interstates, city, or juristictions that state otherwise). Atvs remain illegal to operate on roads in many states due to the fact that manufacturers state plainly that their atvs are not intented to be operated on public roads.

Actually, 1 year ago they made the law that you can ride a ATV (fourwheeler) on any non state roads in Michigan if your four wheeler has the correct appliances, and if you either have your ATV lisence or you are 16 years or older.
