Minnesota DNR Off-Highway Vehicle Regulations
People enjoy using recreational motor vehicles (all-terrain vehicles, off-highway motorcycles and off-road vehicles) for trail-riding, off-road transportation, competition and other activities. Your attitude toward your surroundings and your behavior as a rider affect the attitudes of other outdoor users, landowners and lawmakers. Ride responsibly!

Off-Highway Vehicles in Iowa
Many Iowans enjoy riding Off-Highway Vehicles (OHV) for recreation. Iowa has several designated OHV riding areas, many of which are managed by local clubs, associations or municipal/county governments. The DNR provides law enforcement assistance for these areas. Riders should familiarize themselves with the laws and follow safety guidelines for off-highway vehicle use in Iowa to ensure a safe and enjoyable experience for everyone.
