Which of the following statements is TRUE concerning life jackets?

Correct Answer: Option B — Life jackets are designed to turn an unconscious person's face clear of the water.

46 CFR 160.176 mandates that life jackets must be designed to turn an unconscious person's face clear of the water. This self-righting capability is a fundamental requirement for personal flotation devices, ensuring that even if a crewmember is incapacitated, their airway remains above the water surface.
