The All-Terrain Vehicle (ATV) project is open to 4-H members in grades 3-12. Members should have their own properly-fitted ATV. The National ATV 4-H Handbook will be used as a guide to help determine if a member's ATV is the proper size for them. The 4-H ATV leader has the responsibility and authorization to make this determination for the safety of all participants. ATV's used in this project must have an annual certificate of machine safety inspection prior to inclusion in group riding events.
