Infant Car Seat Crash Test Ratings Explained
Recently, I had a chat with a Child Passenger Safety Technician, and here’s what I found out about the safety ratings:
- While there are no standardized safety ratings for infant car seats in the USA, the manufacturers must test for and meet particular Federal standards.
- The National Highway and Traffic Safety Administration can enforce these standards and recall the ones that don’t meet them.
How Are Infant Car Seats Crash-Tested?
Crash testing is a pretty vigorous safety test. Since the car seat is mounted on rails or a sled, it is also called a sled test.
- Firstly, they secure a crash test dummy into the car seat. Then, the car seat is properly installed on the sled.
- After the installation, the test bench or sled is accelerated or decelerated at different speeds to simulate a 30-mph frontal impact.
- According to the US Department of NHTSA, the car seats must meet the performance criteria in the frontal impact simulation.
- This also includes a side impact test where the car seat goes through a 30-mpg side collision.
The dummy isn’t a mere prop during the crash, sled, or dynamic test. It has sensors that pick up and record particular values during the crash. Based on these values, the manufacturers can rate the car seat on different criteria such as safety, ease of use, durability, etc.
Who Tests The Car Seats?
Both the NHTSA (National Highway and Traffic Safety Administration) and IIHS (Insurance Institute for Highway Safety) are responsible for testing the car seats and awarding safety ratings.

- In the US, manufacturers run tests at various stages of production, but the NHTSA crash test is essential for each car seat to be approved for the market. The NHTSA also continuously updates its testing criteria and standards to ensure optimum safety.
- When it comes to the IIHS, the insurance industry funds it, and it is a non-profit agency that focuses on research to reduce the rate of death, injury, and damage from vehicle crashes. They even invented the small front crash test to measure the impact of a collision between a vehicle and a tree or a pole.
You can also visit NHTSA’s website to check if your car seat or similar equipment has been recalled. This way, you can be sure you are following guidelines and keeping your little ones safe.
How Has The Crash Test Evolved Over The Years?
Crash or dynamic testing was developed in 1970, and during this short time, the test and safety ratings have evolved significantly. Let’s look at the highlights of how it has evolved:
| Year | Development |
|---|---|
| 1971 | NHTSA introduced the first-ever Federal safety standard for infant car seats. |
| 1978 | Tennessee passed the first-ever child passenger safety law – parents were required to put their little ones in a child restraint system or safety seats. |
| 1981 | The Federal government improved safety standards – car beds, rear-facing restraints for infants, and forward-facing seats for kids under 50 lbs were mandated. |
| 1984 | The Child Restraint Task Force of the Society of Automotive Engineers adopted the initiative to create safe car designs to fit child restraints, belts, and vehicle seats together. |
| 1986 | NHTSA found that child restraints can reduce 71% of fatalities and 67% of severe injuries. However, misuse can reduce their effectiveness by 44%. |
| 1990 | Society of Automotive Engineers’ task force made new recommendations on child restraints, seat belt design, and vehicle seats. |
| 1996 | The airbag requirement gets amended by the NHTSA, which includes additional warning labels and cut-off switches for vehicles without smart airbags. |
| 1998 | Dana’s Bill is passed and says that states will receive $30 million for technical training, safety inspection, and child safety restraints or car seat distribution for four years. |
| 2000 | Washington and California passed the first law regarding booster seats for children over 40 lbs. (Took effect in 2002) |
| 2002 | Anton’s Law requiring the standards for booster seat testing was passed. |
| Current | The latest infant car seat requirements include a 5-point safety harness, LATCH system, snug fit for the child and safe restraints. |

What To Look For In An Infant Car Seat
- Choose For Your Child’s Needs: Don’t just go for the best-rated or the most expensive car seat. Choose one based on your child’s weight and size. Avoid relying on age limits, since babies grow at their own pace.
- Compatibility with Baby Gear: Ensure compatibility with other baby gears, like their stroller. Some infant car seats are compatible with all strollers, whereas the UPPAbaby ones aren’t compatible with any other brands.
- Lightweight: Carrying your little bean around won’t be convenient if your car seat is too heavy. Look for a seat you can carry easily with your baby inside.
- Easy Maintenance: Babies are messy. If you’re a mom, you know! So, pick out a car seat that will be easier to clean. I always like removable and machine-washable covers for baby devices.
- Limit Motion: Check for motion-limiting features to ensure optimum safety; for instance, load leg, rear-facing tether, or an anti-rebound bar.
- Standards: Refer to the state laws to find the necessary standards you must comply with, such as federally approved seats.
