S.F. No. 850, the first engrossment, increases the restrictions on the use of off-highway vehicles, which include off-highway motorcycles, off-road vehicles (commonly known as 4x4s), and all-terrain vehicles. The bill requires an operator certificate for operation of off-highway vehicles on public lands. It also provides civil citation authority for the Department of Natural Resources (DNR) to enforce off-highway vehicle laws, limits off-highway vehicle operation on state lands to designated routes and expands the purposes for which money in dedicated off-highway vehicle accounts can be spent to include more enforcement, restitution for property damage, and increased grants-in-aid for local safety and maintenance programs. The bill would also require the DNR to terminate grant-in-aid trail funding to a recipient violating legal or contractual requirements applicable to the grant.
