Which statement about AIS regulations is true?

The statement that all watercraft must be inspected before use is true because it reflects the comprehensive approach of AIS (Aquatic Invasive Species) regulations in Wyoming. These regulations are designed to prevent the introduction and spread of invasive species that can harm aquatic ecosystems. The requirement for inspecting all watercraft, regardless of their type or size, ensures that any potential invasive species are identified and managed before they can enter the waterways. This proactive measure is critical in preserving the state's natural resources and biodiversity.

Other options suggest limitations to the regulations based on type of watercraft or imply that inspections could be optional, which does not align with the intent and enforcement of AIS laws. The regulations encompass all types of watercraft to ensure a holistic approach to managing and protecting waterways.
