MI HB5612

Removes the "eligible county" restriction, allowing any county to adopt ordinances authorizing off-road vehicle (ORV) operation on maintained roads and highways within its jurisdiction, with no fees charged to operators.

Allows townships to adopt ordinances permitting ORV operation on maintained roads within their jurisdiction after a 1-year waiting period following authorization of their county, with no fees charged.

Permits municipalities to adopt ordinances authorizing ORV operation on maintained streets, with operators required to travel on the far right at maximum 25 mph and with lighted headlights and taillights.

Establishes that county road commissioners may close up to 30% of county roads to ORVs only if usage creates significant public safety threats or environmental damage, and requires municipalities to maintain roads used by registered motor vehicle ORVs but not other ORVs.

Provides tort immunity for the state and local governments for ORV-related injuries except in cases of gross negligence, and establishes that ORV operators are prima facie negligent if in collision with other permitted vehicles; violations are municipal civil infractions with maximum $500 fine plus damage repair costs, with collected revenue split equally between law enforcement and road maintenance.
