True or False: A helmet should be replaced after a crash even if no visible damage is seen.

• A. True
• B. False
• C. Only if there is visible damage
• D. It depends on the helmet's age

Answer: (A)

After a crash, you should replace a helmet even if there’s no visible damage. The energy-absorbing foam inside the helmet is crushed during impact, and that crushing is not reversible. Even when the shell looks fine, there can be internal cracks or weakened materials that reduce the helmet’s ability to protect you in a future crash. The retention system and fit can also be stressed, so the helmet may not stay securely on your head next time. Because your protection hinges on the helmet returning to its original shape and strength, replacing it after any significant impact is the safest choice.
