Child Passenger Safety Week: why nearly half of car seats are still used wrong

This week is Child Passenger Safety Week (September 20–26, 2026). The most useful development for parents is not a new seat design. It is a blunt reminder from the Baby Safety Alliance and NHTSA: nearly half of child restraints are installed or used incorrectly, while viral “hacks” and look-alike seats keep spreading online.

Car seats still work when they are the right seat, installed tightly, and harnessed correctly. NHTSA estimates they cut fatal injury risk by about 71% for infants and 54% for toddlers. The gap is not awareness of “use a seat.” It is whether the seat in your car is doing that job.

Background

Parents have been told to use a car seat for decades. What changed is the information environment. Advice now arrives from short videos, marketplace listings, and group chats as often as from a pediatrician or a certified technician. Some clips show coat-over-harness tricks, aftermarket inserts, or cheap copies that look like a known brand.

Child Passenger Safety Week exists because misuse is still common: loose belts, wrong belt path, harness clips too low, seats that have been in a crash, or a child moved forward-facing too early.

Rear-facing for as long as the seat allows remains the standard for infants and most toddlers. AAP guidance is unchanged on the core point: keep children rear-facing until they reach the height or weight limit of that seat, then use a forward-facing harness, then a booster, then the vehicle belt when it fits.

What changed this week

The Baby Safety Alliance’s 2026 campaign line is “Before You Try, Verify.” For car seats they published a four-step S.E.A.T. check:

S — Select a seat that fits this child and this vehicle.
E — Ensure the seat moves less than an inch at the belt path.
A — Adjust the harness snug and flat: at or below the shoulders rear-facing, at or above forward-facing.
T — Technical help from the manufacturer or a certified Child Passenger Safety Technician (CPST).

That last letter is the point. A two-minute video cannot see your vehicle’s LATCH anchors, your child’s winter coat, or a cracked shell.

Competing viewpoints

“The seat clicked in, so we are done.” A click is not a fit check. The one-inch test at the belt path still fails in a large share of family cars.

“Forward-facing looks safer / the child hates rear-facing.” Comfort complaints are real. The evidence still favors rear-facing through the seat’s limit. Switching early trades a known protection for a calmer car ride.

“A cheaper look-alike is the same seat.” Federal standards apply to seats sold for use in the U.S., but copies, expired seats, and seats missing labels or the instruction booklet are a common source of hidden risk. Secondhand can be fine if you know the crash history, recall status, and expiry date.

“Winter coats over the harness keep babies warm.” Bulky coats leave slack when the fabric compresses in a crash. Thin layers plus a blanket over a tightened harness is the usual safer pattern.

What to do this week

Book a free inspection if one is nearby (many fire stations and hospitals host CPSTs during this week).
Check recalls on the manufacturer site and NHTSA.
Confirm the expiry date molded into the plastic.
Do the one-inch test and the pinch test on the harness.
Ignore coat-over-harness and “hack” clips that did not come with the seat.

This is not medical or legal advice. Use your seat manual and a certified technician when something does not match the booklet.

What to watch next

Whether marketplace platforms keep listing noncompliant look-alikes.
Local inspection hours through the end of Baby Safety Month.
Your child’s next height/weight check against this seat’s printed limits — not a social-media age chart.
