can car seats be reused

[DeGianna]

No, car seats should generally not be reused, especially if they are expired, have been in a moderate or severe crash, or have unknown history. The primary reason is safety. A car seat's structural integrity can be compromised in ways that are not visible to the naked eye. Reusing a seat without knowing its full history introduces significant and unnecessary risk for your child.

The decision hinges on several critical factors. First, check the expiration date. Most car seats expire 6 to 10 years after their manufacture date. Plastics and other materials degrade over time due to temperature fluctuations and sunlight exposure, weakening their ability to withstand crash forces. The expiration date is usually stamped on the shell.

Second, consider crash involvement. The National Highway Traffic Safety Administration (NHTSA) states that car seats involved in a moderate or severe crash must be replaced. However, seats in minor crashes can often be reused if specific criteria are met: the vehicle was drivable from the crash site, the door nearest the car seat was undamaged, no vehicle occupants were injured, and the airbags did not deploy. If any of these criteria are not met, the seat must be replaced.

For used seats, the "history unknown" rule is paramount. If you cannot be 100% certain of a seat's history—including whether it was in a crash, recalled, or improperly cleaned—it is not safe to use. Always check for recalls on the NHTSA website using the model number and manufacture date.

Car Seat Brand	Typical Expiration Period (Years)	Key Consideration
Graco	7-10	Varies by model; check label.
Britax	6-10	Many models have a 10-year life.
Chicco	6-8	KeyFit infant seats often expire at 6 years.
Evenflo	6-10	Expiration is clearly marked on the seat.
Maxi-Cosi	6-8	Follow the printed expiration date strictly.
Clek	7-9	Some booster models have a 9-year life.
Diono	7-10	Radian series often has a 10-year limit.
UPPAbaby	7	MESA infant seat expires 7 years from manufacture.
Nuna	6-7	PIPA series typically has a 6-year lifespan.
Cybex	7-10	Cloud Q infant seat expires after 7 years.

Ultimately, your child's safety is not an area for compromise. When in doubt, replace the car seat. Many retailers offer trade-in events, providing a discount on a new seat when you recycle an old one, making the safe choice more affordable.

As a mom of three, I’ve reused car seats exactly once: when it was my own seat, moving it from my old car to my new van. I knew its entire history—never in a crash, well before its expiration date. I would never grab one from a garage sale or use a hand-me-down from a friend without asking a million questions. You just can't see the stress that plastic has been through. It’s not worth the gamble.

Think of a car seat like a bicycle helmet. It’s designed for one major impact. After a crash, the energy-absorbing foam inside is compressed. It may look fine, but it won’t protect your child the same way again. The same logic applies to time. The plastics get brittle. The expiration date isn’t a suggestion; it’s an engineering calculation. The safest move is always a new seat or one with a known, pristine history.
