Which of the following statements about helmet retirement is true?

• A. Condition
• B. Age
• C. Manufacturer's rec
• D. Lifetime

Answer: (C)

The main idea is to retire helmets according to the manufacturer’s recommendations. This is the best guidance because the manufacturer has tested how long a helmet maintains its protective ability for that exact model, considering materials, design, and typical use. Following their timeline helps ensure you’re not keeping a helmet that may no longer provide reliable protection, while also avoiding retiring it too soon.

While visible wear or age can matter, they aren’t the official standard on their own. A helmet might still look fine but have degraded performance, or, conversely, a model may last longer than a rough age estimate. Relying on the manufacturer’s rec provides a consistent, model-specific retirement point that safety programs use.
