Important correction: NHTSA’s current guidance does not require automatic replacement after every crash. NHTSA recommends replacing a car seat after a moderate or severe crash. After a minor crash, replacement may not be necessary if the crash meets all five of NHTSA’s minor-crash criteria and the car seat manufacturer permits continued use.[1]
The Short Answer
Your child’s car seat may need to be replaced after what seems like a minor accident—but not because NHTSA has adopted a blanket “replace after any crash” rule.
The correct decision depends on two things:
- Whether the crash meets every part of NHTSA’s definition of a minor crash.
- What the instructions for your exact car seat or booster seat say about post-crash use.
Some manufacturers require replacement after any crash, even when all five NHTSA criteria are met. Others permit continued use after a qualifying minor crash. Always follow the instructions for the specific model involved.
How NHTSA Defines a Minor Crash
Under NHTSA’s current guidance, a crash is considered minor only when all five of the following statements are true:[1]
- The vehicle could be driven away from the crash site.
- The vehicle door nearest the car seat was not damaged.
- No passenger in the vehicle was injured in the crash.
- If the vehicle had air bags, none of them deployed.
- There is no visible damage to the car seat.
If even one statement is not true, the crash does not meet NHTSA’s minor-crash definition. Set the seat aside and do not use it while arranging replacement or obtaining instructions from the manufacturer.
NHTSA says a car seat involved in a moderate or severe crash should be replaced and should never be used again.[1]
A Practical Post-Crash Decision Guide
| Situation | What to Do |
|---|---|
| All five NHTSA minor-crash criteria are met, and the manufacturer permits reuse | The seat may not need automatic replacement. Follow the manual’s inspection and continued-use instructions. |
| All five criteria are met, but the manufacturer requires replacement after any crash | Replace the seat. |
| One or more NHTSA criteria are not met | Do not continue using the seat. Arrange replacement and follow the manufacturer’s instructions. |
| You cannot determine whether all five criteria were met | Stop using the seat until the manufacturer provides guidance. Replace it if its crash history cannot be verified. |
| The manual is missing or the model cannot be identified | Contact the manufacturer using the model number and date-of-manufacture label. If the seat cannot be identified or its instructions obtained, do not use it. |
Why “It Was Only a Fender-Bender” Is Not Enough
Descriptions such as “minor accident,” “parking-lot bump” and “low-speed collision” are not enough to make the decision. NHTSA’s minor-crash test does not use a specific miles-per-hour cutoff.
A low-speed crash may still fail the test if, for example:
- An occupant was injured.
- An air bag deployed.
- The door nearest the car seat was damaged.
- The vehicle could not be driven away.
- The seat, base, harness, belt guide or lower-anchor hardware shows damage.
Likewise, the lack of visible damage does not, by itself, prove that the seat can be reused. “No visible damage” is only one of NHTSA’s five requirements, and the manufacturer may still require replacement.
The Manufacturer’s Instructions Can Be Stricter
NHTSA specifically tells caregivers to follow the car seat manufacturer’s instructions.[1] American Academy of Pediatrics parent guidance also notes that some manufacturers recommend replacement after any crash, including a crash that meets NHTSA’s minor-crash criteria.[5]
Check the section of the manual labeled “After a Crash,” “Vehicle Crash,” “Replacement” or similar wording. Policies may differ between models, so do not rely on a general online chart for the entire brand.
If the manual is unclear:
- Find the model number, serial number and date of manufacture on the seat’s label.
- Contact the manufacturer directly.
- Describe the crash and each of NHTSA’s five criteria.
- Ask for written confirmation of whether the seat, detachable base or both must be replaced.
Do not let an insurer’s willingness or refusal to reimburse determine whether the seat is safe to use.
What to Do Immediately After a Crash
- Attend to injuries first. Call 911 for an emergency. If any occupant was injured, the crash does not meet NHTSA’s minor-crash definition.
- Do not place the child back in a seat that clearly must be replaced. Use another appropriate car seat with a known history, no unresolved recall and no expired service life.
- Photograph the scene when it is safe. Document the vehicle damage, the door nearest the seat, air-bag status and the seat in its installed position.
- Photograph the car seat labels. Capture the manufacturer, model number, date of manufacture and serial number, if present.
- Inspect without taking the seat apart. Look for cracks, deformation, torn webbing, damaged connectors, stress marks or broken components. Do not attempt an unauthorized repair.
- Read the manual and contact the manufacturer. Include the detachable base, if one was used.
- Document the crash for insurance. Save the crash report or driver-exchange information, photographs, repair estimate and manufacturer instructions.
Infant Seat Bases, Convertible Seats and Boosters
Post-crash instructions may apply to more than the part in which the child sits.
Infant Seats With Detachable Bases
If an infant seat was attached to a base during the crash, ask whether the carrier, base or both must be replaced. Do not assume the carrier is unaffected simply because most of the installation hardware is in the base.
Convertible and All-in-One Seats
Follow the same NHTSA criteria regardless of whether the seat was rear-facing, forward-facing or being used in booster mode. Also check the model’s instructions for the harness, tether and lower-anchor components.
Booster Seats
Boosters are child restraints and have manufacturer instructions that must be followed. Check the booster’s manual after any crash, even if it was unoccupied or was not attached to the vehicle at the time.
What If the Car Seat Was Empty?
NHTSA’s five-part minor-crash test does not include an exception for an unoccupied seat.[1] Evaluate the crash using the same criteria and follow the manufacturer’s instructions.
Do not assume that an empty seat can automatically be reused. Conversely, do not assume NHTSA automatically requires replacement solely because the seat was present. The crash classification and the manufacturer’s policy remain the deciding factors.
What If More Than One Car Seat Was in the Vehicle?
Evaluate every seat separately. The door nearest one car seat may be damaged while the door nearest another is not. The seats may also be different models with different manufacturer policies.
Record each seat’s:
- Seating position
- Nearest vehicle door
- Visible condition
- Model and manufacture date
- Installation method
- Manufacturer’s post-crash instructions
How to Handle an Insurance Claim
Insurance coverage and claim procedures vary. NHTSA’s safety guidance does not guarantee that an insurer will automatically reimburse you.
To support a claim:
- Notify the insurer that a child restraint was in the vehicle.
- Provide photographs and the seat’s model information.
- Include the relevant page from the instruction manual or a written response from the manufacturer.
- Explain which NHTSA minor-crash criteria were not met, if applicable.
- Ask whether the carrier, base and any additional seats are handled as separate items.
- Keep receipts for replacement seats.
- Ask before discarding the crashed seat in case the insurer needs photographs or other documentation.
If the seat must be replaced, do not continue using it while waiting for a claim decision. Use another appropriate seat that fits the child and vehicle and can be installed according to both manuals.
Used Car Seats and Unknown Crash History
NHTSA says a secondhand seat may be acceptable only when its history and condition can be verified. It should not have been involved in a moderate or severe crash, and it must have its model and manufacture-date labels, all required parts, instructions and no unresolved recalls.[2]
Before using a secondhand seat, confirm that:
- You know its complete crash history.
- Any previous minor crash met all five NHTSA criteria.
- The manufacturer permitted continued use after that crash.
- The seat is within the manufacturer’s stated service life.
- It has no cracks, missing parts or unauthorized repairs.
- Its model and manufacture date can be checked for recalls.
Avoid a used seat if its history is unknown. Check car seats and other vehicle equipment through NHTSA’s recall search.[4]
Can a CPST Decide Whether the Seat Is Safe?
A certified Child Passenger Safety Technician can help you locate and understand the instructions, select an appropriate replacement and check that the new seat is installed and used correctly. NHTSA provides a locator for inspection stations, many of which offer checks at no charge.[3]
A technician’s visual inspection should not override NHTSA’s criteria or the manufacturer’s post-crash instructions. If the manufacturer requires replacement, a normal-looking seat should still be replaced.
After installing a replacement, see How to Know if Your Car Seat Is Installed Correctly Without Paying a Technician for an at-home installation review. When possible, also arrange a check with a qualified CPST.
How to Dispose of a Seat That Must Be Replaced
Before disposal, confirm that the insurer and manufacturer no longer need the seat or its labels.
To discourage reuse:
- Do not sell or donate the seat.
- Mark the shell clearly with “CRASHED—DO NOT USE.”
- Remove or cut the harness straps when appropriate.
- Separate removable components if local disposal rules permit.
- Follow local trash or recycling requirements.
Do not use a crashed seat as a travel, backup or grandparent seat if NHTSA or the manufacturer says it must be replaced.
Frequently Asked Questions
My car was bumped in a parking lot. Must I replace the seat?
Not automatically under NHTSA guidance. Apply all five minor-crash criteria and then check the manufacturer’s instructions. Speed alone does not answer the question.
The insurer says the crash was under 10 mph. Does that make the seat safe?
No specific speed cutoff appears in NHTSA’s five-part minor-crash definition. Confirm all five criteria and follow the seat manufacturer’s instructions.
The seat looks completely normal. Can I keep using it?
Appearance is only one factor. The crash must meet all five NHTSA criteria, and the manufacturer must permit continued use.
No child was riding in the seat. Does that change the rule?
NHTSA’s criteria do not include an exception for an empty seat. Follow the same assessment and the manufacturer’s instructions.
The seat was installed with a vehicle belt instead of lower anchors. Does that matter?
The NHTSA minor-crash criteria remain the same. Check the seat and vehicle manuals for instructions concerning the installation components involved.
Should I replace only the infant carrier or only the base?
Do not guess. Check the manual or ask the manufacturer whether the carrier, base or both must be replaced.
Can I repair a cracked shell or damaged harness?
Do not make an improvised repair. Follow the manufacturer’s instructions. A seat with visible crash damage does not meet NHTSA’s minor-crash definition.
The Bottom Line
As of August 10, 2026, NHTSA does not recommend automatic car seat replacement after every minor crash. A seat may be considered for continued use only when all five minor-crash criteria are satisfied and the manufacturer allows it.
Replace the seat when the crash was moderate or severe, when any minor-crash criterion is not met, or when the manufacturer requires replacement after any crash. When the crash details or seat history cannot be verified, set the seat aside and obtain guidance before transporting a child in it.
