When considering reuse of a bicycle helmet, which statement is appropriate?

• A. As long as the helmet does not have cracks, you may use it.
• B. If the helmet is free from marks, you may use it.
• C. You may continue to use a helmet up to 10 years.
• D. You should always purchase a new helmet for each child.

Answer: (B)

The main idea here is how to judge whether a helmet can be reused based on signs of damage. A bicycle helmet should be discarded if there’s evidence of compromise to its protective ability, such as visible damage, a distorted shell, cracked foam, or a broken or frayed strap. If the helmet shows no signs of impact or wear—specifically, it is free from marks that would indicate past damage—it is reasonable to reuse it, assuming it still fits properly and there’s no other damage. This approach avoids assuming safety simply because there’s no cracked shell, and it’s more practical than sticking to a rigid age rule, since replacement timing can vary by manufacturer and use. In short, when there are no marks or other damage indicating prior impact, reusing the helmet is acceptable; replace if there’s any sign of damage or a significant crash.
