How often should bicycle helmets be replaced?

• A. Every year
• B. Every 2 years
• C. Every 5 years or sooner
• D. Never

Answer: (C)

The main idea is that bicycle helmets don’t last forever. The protective foam that absorbs impact and the outer shell can degrade over time from sun exposure, heat, sweat, and normal wear. Even if a helmet looks fine, the energy-absorbing material can lose its ability to protect you after years of use. Because of that, helmet manufacturers and safety groups generally recommend replacing a helmet about every five years, or sooner if there’s any damage. A crash is a clear trigger to replace a helmet, since an impact can create invisible cracks or weaknesses in the foam or straps. Before using a helmet, you can also check for signs of trouble: cracks, dents, frayed straps, or a loose or broken buckle. It’s helpful to look for the date of manufacture stamped inside the helmet, because some brands set a shelf life based on time rather than years of use. So, the best practice is to replace the helmet every five years or sooner if it shows damage or has been involved in a crash. This isn’t about replacing on a strict yearly schedule or never; it’s about ensuring the protective materials are still reliable to shield the head during an impact.
