It is really very plain and simple. The ORV laws in the state of Michigan are so filled with gray areas, that the laws are left to interpretation by the various DNR Districts. Ask two different districts the same question, you get two different answers.
After years of going to ORV Advisory meetings ( we are speaking of a period over two decades ), it has been proven over and over again that most DNR officers don't even have a clue ( not entirely their fault ), so they make up their own interpretations.
The only way you can really clarify this entire topic is to take a trip to the next ORV Advisory meeting ( Nov 4th )and find out the "Real Deal". Make sure to take your blood pressure medication before you go though, those meetings will make your blood boil.
The lawmakers DO want to eliminate four wheeling on state lands and they DO want four wheeling entirely pushed off into private off road parks. They CANNOT dictate the use of ORV stickers on private off road parks without relinquishing some of their ORV dollars to the private parks, which they are NOT about to do at this time.
