More than 700 child passengers aged 12 and below died in motor vehicle crashes in 2021, the latest year for which data is available. To note, nearly 40 percent were not buckled in. And even when appropriate safety gear like restraints and booster seats are used, they’re used incorrectly nearly half the time, according to the Centers for Disease Control and Prevention (CDC). Reading up on your child’s safety restraint systems could help you keep them safe.

Car seat safety statistics and facts

Car seat safety statistics and car seat death statistics are never easy to read. However, arming yourself with the facts may help to improve the outcome in the event of an accident.

Car seat recommendations based on a child’s age and size

Several different types of cars are available to help keep your child safe. Your child’s age and individual needs will likely influence the type of car seat that works best for them.

Rear-facing car seat

  • Best for infants, from newborns to three-year-olds
  • Designed to mitigate stress to the child’s fragile neck and spinal cord

Forward-facing car seat

  • Best for toddlers between the ages of four and seven
  • Designed with a buckled harness that limits your child’s movement in the event of an accident

Booster seat

  • Best for children between the ages of four and 12
  • Raises a child’s body so that the car’s seat belt sits correctly over the child’s hips and chest

Seat belt

  • Best for children and adults ages 12 and above, provided they’re big enough so that the belt fits properly
  • Should fit snugly across thighs, shoulder and chest

Car and booster seat safety laws by state

If you’re looking for ways to keep your family safe in the car, remember that enforcing seat belt use is one of the best ways to do that. Each state has its own booster seat guidelines and car seat laws.

Replacing a car seat after a collision

A lesser-known car seat safety fact is that car seats need to be replaced after a collision — even a relatively minor one. Car accidents involve significant forces and those forces get absorbed by the vehicle and its contents. Car seats are designed to absorb some of that force to keep the child in the seat safe.

The plastic of a car seat can be damaged or weakened by a crash, even if the seat doesn’t show any signs of damage and looks like it is fine to use. It’s better to be safe and replace your child’s car seat after a collision to reduce the risk of injury (or worse) should an accident occur in the future.

Under NHTSA guidelines, if any of these apply to your collision, you should replace the car seat:

  • The vehicle cannot be driven away from the crash site.
  • The door nearest the seat was damaged.
  • Any of the passengers in the vehicle sustained injuries.
  • The airbags deployed.
  • There is visible damage to the seat.

Does car insurance cover car seat replacement?

If you get into an accident, the NHTSA recommends that you replace car seats to keep your children safe. The good news for parents is that insurance companies typically help cover the cost of a new car seat if your policy includes collision coverage. When filing your insurance claim, make sure to inform the insurer that you have a car seat that will need to be replaced.

Frequently asked questions

    • Five-point harness car seats should have height and weight limits listed on them. Typically, children are ready to graduate from car seats to booster seats between the ages of five and nine.
    • Your booster seat should note height and weight recommendations on it. When your child is seated in the booster seat, the seat belt should fit snugly across the child’s torso and hips without being uncomfortable.
    • The first step is to make sure your child is properly restrained in the car. Ensure that your child doesn’t exceed the height and weight limits listed on their car seat or booster seat. Never leave children in a hot car — even if you’re just running inside for a moment. Talk to your children about not playing near vehicles and staying away from cars when they’re backing up.
    • Car insurance rates vary a lot between people because insurance companies use multiple factors to calculate your rate, including your driving record, information about your vehicle and personal information about you. That said, finding cheap car insurance doesn’t have to be difficult. One of the easiest ways to find the cheapest car insurance for your situation is to request quotes from several insurance companies for the same coverage types and levels and compare.
    • Some of the most common mistakes people make when using car seats or booster seat include:
      • Installing the car seat improperly: Even similar-looking seats may have different installation requirements, and installed seats should move no more than one inch from side to side.
      • Placing the chest clip incorrectly: A chest clip that is too low may allow the child to be ejected from the seat. One placed too high could cause a neck injury. In general, the clip should align with the child’s armpits.
      • Choosing the wrong seat: In general, children three and under should be in a rear-facing seat, and those four and up should have a forward-facing seat with a harness.
      • Using an expired seat: Car seats usually expire six years after they’re made as the plastic becomes more brittle and parts become worn.
