Across the vehicles we have checked, the buckle is what decides it. Buckles on tall, stable stalks stand up on their own and a child can grab them. Buckles that sit flush with the seat cushion, or flop over on a loose strap, disappear under the booster and need an adult. It is the single most common reason a vehicle loses points on the booster test, and almost nobody checks it on a test drive.
Compiled by our gear team from Cars.com's Car Seat Check. Published July 18, 2026. Booster findings are from Cars.com's Car Seat Checks, conducted by certified child passenger safety technicians, and we have written up each vehicle individually.
Why this matters more than it sounds
The booster years last a long time. NHTSA guidance is that a child stays in a booster until the adult seat belt fits properly, generally around 4 feet 9 inches tall and somewhere between ages 8 and 12. That is years of getting into a car.
If your child can buckle themselves, that is one less thing on every school run, every nursery drop-off, every trip in the rain with your arms full. If they cannot, you are leaning into the back seat several times a day for years.
Nobody checks this on a test drive. It never appears in a brochure. And it is the single most common reason a vehicle drops a grade on the booster test.
What a good buckle looks like
The pattern is consistent across every vehicle we have looked at.
- Good: the buckle sits on a tall, rigid stalk that stands upright on its own. A child can see it and grab it without digging.
- Bad, version one: the buckle sits on a short stalk flush with the seat cushion. Once a booster is in place, it is level with or under the booster's base and small hands cannot get at it.
- Bad, version two: the buckle is on a long floppy strap. It lies flat, slides under the booster, and has to be fished out every single time.
You can test this in ninety seconds in a dealership parking lot. Put your child in the seat and ask them to buckle up. That is the whole test, and it will tell you more about the next eight years than the brochure will.
Vehicles where kids should manage on their own
| Vehicle | What Cars.com found |
|---|---|
| 2027 Kia Telluride | Stable stalks kids can grasp. |
| 2025 Subaru Crosstrek | Large, relatively stable stalks. The reason it swept every test. |
| 2022 Toyota Sienna | Stable buckles kids should manage alone. |
| 2025 Ford F-150 | Rigid and high enough, but only in the middle and passenger positions. The driver's-side buckle is floppy. |
| 2025 Kia Carnival | Outboard buckles on stable stalks. The middle buckle is floppy. |
| 2025 Kia EV9 | Tall, stable stalks. |
| 2025 Ford Expedition | Sturdy and tall. |
| 2025 Toyota Tundra | Short but stable, on a wide flat seat. |
| 2026 Chevrolet Traverse | Large, on tall stalks anchored to the seat. |
| 2025 Volkswagen ID. Buzz | Stable stalks. |
| 2023 Honda CR-V | An A. After raising the head restraint to sit the booster flush against the seatback, it fit well, and Cars.com noted the buckles sit on stable bases just above the seat cushion, making them easy to grasp. |
Vehicles where they will probably need help
| Vehicle | What Cars.com found |
|---|---|
| 2025 Tesla Model 3 | Buckles sit flush in the seat bight and the booster slides over them. Fixed head restraint pushes the booster off the seatback. |
| 2023 Honda Civic | Floppy buckles, plus a fixed head restraint that stops the booster sitting flush. |
Somewhere in between
These earned a B, usually because the booster itself fits well but the buckle is awkward, or the head restraint has to come out first. Workable, with some friction.

The vehicles that got everything right
A small number swept every second-row test Cars.com runs, booster included. Since booster is the grade most vehicles lose, this is a short and useful list.

One thing the grade does not tell you
A vehicle can have excellent buckles and still be wrong for you, and an awkward buckle is not a crash-safety rating. A booster's protection comes from being used correctly every time.
What an awkward buckle costs you is friction, several times a day, for years. That is worth weighing when you choose a car rather than panicking about.
Choosing the booster itself
Seat choice affects this too. A high-back booster with a deep base can bury a low buckle that a backless booster would leave clear, and a narrower booster leaves more room to get a hand in beside it. If you are close, that is the lever you have.
Browse the car seats we carry, and if you are trying to work out when your child is actually ready for a booster at all, our guide to booster readiness covers the height, weight and maturity markers that matter more than age.

How a car seat fits and installs depends on your exact vehicle (its model year, trim, and seating configuration) and your exact car seat model. The instructions that came with your car seat and your vehicle owner’s manual always control. If anything in this article ever conflicts with those instructions, or with current guidance from the National Highway Traffic Safety Administration (NHTSA), follow the manufacturer instructions, your vehicle manual, and NHTSA, not this article.
Our fit findings are compiled from third-party sources, including independent car seat fit testing performed by Certified Child Passenger Safety Technicians and manufacturer specifications, that we believe to be reliable, and we provide all of it “as is.” Specifications, model years, and vehicle configurations change, and we do not guarantee the accuracy, completeness, or current status of any of it.
