Start by separating a clearly minor crash from everything else

NHTSA’s minor-crash guidance only applies when every listed condition is satisfied.

Crash meets every minor-crash criterion
A possible continued-use decision if the seat manufacturer also allows it

Confirm all five NHTSA conditions, inspect the seat carefully, and then check the manufacturer’s instructions. A single failed criterion means the crash does not fit this minor-crash definition.

Moderate or severe crash
Replacement rather than continued use

NHTSA recommends replacing car seats after moderate or severe crashes because hidden damage can affect future crash protection.

Crash severity or seat history is uncertain
A conservative replacement decision

If you cannot verify what happened, cannot confirm the seat’s history, or cannot get clear manufacturer guidance, do not assume the seat is safe because it looks normal.

A NHTSA minor crash must meet all five conditions

  • The vehicle was able to be driven away from the crash site
  • The vehicle door nearest the car seat was not damaged
  • No passengers in the vehicle sustained injuries in the crash
  • The vehicle’s air bags did not deploy
  • There is no visible damage to the car seat

The car-seat manufacturer can be stricter than the general NHTSA guidance

Car seats are certified products with model-specific instructions, materials, expiration rules, and replacement policies. Some manufacturers may instruct owners to replace a seat after any crash or may define their own conditions for continued use.

That means the NHTSA checklist is not a shortcut around the product manual. Find the model name, model number, and date of manufacture on the seat, then read the manufacturer’s crash policy or contact the manufacturer if the instructions are unclear.

Insurance coverage can also vary. Keep crash photos, the police or incident report if one exists, the seat model information, and any manufacturer replacement guidance in case your insurer asks for documentation.

Stop and get help

Do not rely on appearance alone after a meaningful collision

A child restraint can look normal while having been loaded in a crash. If the collision was moderate or severe, any NHTSA minor-crash criterion is not met, the seat shows damage, or the manufacturer requires replacement, do not transport a child in that seat again. Replace it according to the manufacturer’s instructions and dispose of the old seat in a way that discourages reuse.
