Which statement best reflects mandatory PFD usage on board?

• A. PFDs are optional for adults
• B. PFDs are required only in rough seas
• C. PFDs must be worn only by passengers when underway
• D. PFDs must be worn by everyone on board when underway or in risk of immersion

Answer: (D)

PFDs should be worn by everyone on board whenever the boat is underway or there’s any risk of immersion. This rule ensures immediate protection if someone falls overboard, and it applies to all people on the vessel, not just adults or passengers. PFDs should be Coast Guard–approved, properly sized, and worn correctly, with life jackets kept readily accessible so they can be put on before immersion risk occurs. The other statements don’t fit because safety isn’t limited to rough seas, to adults, or to passengers only; universal readiness is the aim.
