How old must you be to legally wear an inflatable PFD?

To legally wear an inflatable personal flotation device (PFD), you must typically be at least 16 years old, according to U.S. Coast Guard regulations. However, specific age requirements may vary by state or local laws, so it's important to check the regulations in your area. Additionally, some states may have restrictions regarding the use of inflatable PFDs for younger individuals, even if they are accompanied by an adult. Always ensure you are compliant with local regulations for safety.
