This bill establishes legal immunity for motocross facilities in Iowa regarding civil liability actions. It defines key terms such as "facility operator," "inherent risks of motocross activities," and "participant." Under the new law, a motocross facility will not be liable for injuries or deaths resulting from the inherent risks associated with motocross activities, and participants or their representatives are prohibited from making claims against the facility for such incidents. However, the bill outlines specific exceptions where liability may still apply, including cases of intentional injury, negligence, provision of unsafe equipment, or failure to exercise reasonable care.

Additionally, the bill mandates that all motocross facilities must post warning signs in visible locations, informing participants of the legal immunity provisions. The signs must include a specific warning notice regarding the facility's liability limitations. Importantly, the bill clarifies that it does not alter any existing claims or defenses under current law and does not affect claims arising from incidents that occurred before the bill's effective date.
