A fall during bike riding, skateboarding, or scooter use may seem minor, but if a child’s bike helmet hits the ground, replacement should be considered immediately. A bicycle helmet is typically designed to withstand one significant impact. After a crash, the helmet’s inner foam may be compromised, even if there’s no visible damage. This internal breakdown weakens the helmet’s ability to protect a child’s head in the event of another impact.
The Consumer Product Safety Commission advises that any time a helmet is involved in an accident where the child’s head hits the pavement or another surface, a new helmet should be used. Safety standards exist for a reason, and most helmets that experience a direct impact are no longer safe for future use.

Key Signs a Child’s Helmet Needs Replacing
After a fall, inspect the helmet carefully. Look for cracked foam, a damaged outer shell, loose or frayed straps, or a deformed shape. Even small cracks or dents may suggest the helmet’s protection has been compromised. The foam inside is designed to absorb shock by crushing on impact, and it doesn’t rebound afterward.
If your child’s helmet was stored in a hot car for extended periods, its materials may degrade even without a fall. Heat can warp the plastic shell and weaken the foam lining, reducing its ability to absorb energy during a crash. Any helmet that has endured extreme heat, appears cracked, or fits poorly should be replaced.
Helmets Are Built for One Crash
Most helmets are certified under safety standards that assume a single crash. Once that crash occurs, the foam liner’s structure changes, even if the helmet looks fine. After one fall where the child’s head makes contact, it is no longer safe to assume the helmet offers full protection.
Riding with a compromised helmet puts a child at risk for serious injuries, including concussion or traumatic brain injury. The helmet’s job is to protect, but it can only do so effectively once. Replacement is a necessary part of safe riding.
Be Cautious with Hand-Me-Down or Older Helmets
While hand me down helmets might seem like a practical option, they can present safety risks. Without knowing the history of the helmet, it’s impossible to determine whether it’s been in a crash. Older helmets may also fail to meet current safety standards. If the helmet lacks a clear certification label, such as a Snell sticker inside or a Consumer Product Safety Commission tag, it should not be used.
Manufacturers also recommend replacing helmets after five years, regardless of whether they’ve been involved in a crash. Over time, exposure to sun, heat, and moisture can weaken the materials. A child’s helmet that is more than five years old is likely not offering the level of protection intended.

Choosing and Fitting a New Helmet
When selecting a replacement, ensure the helmet fits properly. A properly fitting helmet sits level on the head, covers the forehead, and does not move around when the child shakes their head. The straps should form a “V” under each ear and buckle securely under the chin.
Look for helmets that meet or exceed safety standards from organizations like the Consumer Product Safety Commission, ASTM, or Snell. These helmets undergo rigorous testing and offer better protection. Avoid novelty helmets or toy-grade designs that may not include impact-resistant materials or proper foam construction.
Fit is just as important as function. A helmet that is too loose, sits too far back, or has broken buckles can’t do its job. Skate style helmets and bike helmets each have different design intents, so always ensure the right type is being used for the activity.
Safe Use and Helmet Care with Brown Chiari LLP
Routine helmet care is essential. Store the helmet indoors in a cool, dry place. Avoid leaving it in direct sunlight or in a hot car, both of which can cause the materials to deteriorate. Check regularly for cracks, loose straps, or other signs of damage. Teach your child to treat their helmet as protective gear, not just another piece of clothing. A damaged or worn out helmet is not just a cosmetic issue, it’s a safety hazard.
If there’s ever any doubt about whether a helmet is still safe, it’s better to err on the side of caution and replace it. Protection cannot be guaranteed by looks alone. When it comes to your child’s head, safety must come first.

FAQs About Replacing a Child’s Bike Helmet
Yes, if the child’s head hit the ground. Even if the helmet looks fine, internal damage may prevent it from protecting effectively in another crash.
Looks can be deceiving. The internal foam may be crushed or cracked in ways that aren’t visible. Always consider replacing the helmet after a significant fall.
If it’s under five years old, hasn’t been in a crash, and was stored properly, it might be fine. However, once five years have passed, replacement is recommended due to material degradation.
Only if you know for certain the helmet has never been in a fall and it still meets safety standards. If there’s any uncertainty, replace it.
Look for a Snell sticker inside or a certification mark from the Consumer Product Safety Commission. These indicate that the helmet meets tested safety standards for impact resistance.
