Which of the following statements is true regarding helmet safety?

The statement that helmets should be replaced after any crash is accurate and highlights an important aspect of motorcycle safety. When a helmet is involved in a crash, it may sustain damage that is not always visible on the outside. The protective foam inside the helmet is designed to absorb impact, and even if the outer shell looks fine, the integrity of the helmet may be compromised. Using a helmet that has been in a crash can increase the risk of head injury in a subsequent incident, as it may not provide the same level of protection.

Understanding this principle is crucial for all riders; regularly inspecting helmets for visible signs of damage or wear and adhering to replacement recommendations can significantly enhance safety while riding. Furthermore, helmets are designed with a specific lifespan due to materials degrading over time, which is another reason to prioritize the replacement of any helmet that has experienced a significant impact.

The other options do not accurately reflect best practices in helmet safety. For instance, a helmet cannot be used indefinitely just because it appears to be in good condition; it should be regularly inspected and replaced according to the manufacturer's guidelines or after any crash.
