The number of children who have died in motor vehicle-related crashes has decreased by around 61% since the mid-’70s.1,2 That's fabulous news, but some concerning statistics still need improvement.

For example, 26% of all children under the age of 15 who died in car crashes in 2022 were unrestrained with a restrained driver.   Plus, studies suggest that children are between 54% (toddlers) and 71% (infants) less likely to sustain a fatal injury if they're secured in a properly installed car seat.3

In addition to driving safely, the most important thing you can do to keep your child safe in the car is to buckle them into an age-appropriate and properly installed car seat. It’s estimated that at least 11,606 children under the age of four have been saved by car seats between 1975 and 2017.4 Some states have passed child car seat laws to encourage parents to do this, and we wanted to know if stricter laws meant lower fatality rates.


Child car crash fatality rates and restraint laws

It turns out that stricter state car seat laws don’t strongly correlate with lower car-related child fatality rates. In fact, if you look at the comparison charts below, you'll see that the states with the highest child traffic crash fatality rates were more likely to have extended rear-facing and booster seat requirements than the states with the lowest child fatality rates.

Only one state (Montana) fits the expected profile of a state with virtually no child restraint laws and a high child fatality rate.

We're certainly not discrediting the importance of child safety laws, but our analysis shows that keeping kids safe in cars is way more nuanced than enacting legislation.

Other factors may include whether the child restraint was installed and used correctly, the type of vehicle involved in the crash, vehicle speed at impact, etc.

Top 10 states with lowest child traffic crash fatality rates

According to the NHTSA, fatal car crashes involving children happened most (and least) frequently in these states in 2022—the most recent year with available data5,13 The numbers shown are representative of every 100,000 children in each state. For example, for every 100,000 children in Mississippi, 4.34 were killed in a motor vehicle crash.

Additional findings

While we didn’t find a direct correlation between lax state laws and traffic deaths, some interesting national findings are worth mentioning.

  • In 2022, 859 children under the age of 12 and 270 children ages 13 to 14 died in car accidents. An additional 156,502 other children from infancy to age 14 were injured.1
  • Twenty-eight years earlier, in 1994, the numbers were even worse: 1,123 children under 10 and 1,133 children ages 10 to 15 died in car accidents.2
  • The number of children who died in car accidents in 2022 decreased by 6% compared to the previous year.
  • Fatal vehicle accidents involving children have decreased by 61% since 1975.7
  • Idaho allows children to ride out of their safety seat if held by an attendant for “nursing or to meet another immediate physiological need.”8
  • Two children died while riding the school bus in 2020. A total of 70 school bus passengers died in traffic crashes between 2010 and 2020.9
  • The use of car seats for children between 4 and 7 years old dropped from 91% in 2011 to 86.2% in 2019.10,11
  • Of the children younger than 1 year old who died in motor vehicle accidents in 2020, 25% were unrestrained. The percentage of unrestrained children in fatal vehicle accidents increases to 30% for children 1 to 3 years old and 39% for children 4 to 7 years old. It falls slightly to 36% for children 8 to 12 years old before rising again to 51% for kids ages 13 or 14.5

How to keep children safe in the car

Driving safely and using the right safety restraints for your kids is the best way to prevent traffic fatalities. The correct seat for your child will depend on their height, weight, and age. The best car seats are comfortable for your kids and easy for you to install.

Follow these car seat dos and don’ts every time.12

Always read the instructions before installing your child’s car seat for the first time.

Always check to make sure your kids are secured tightly before every ride. The car seat shouldn’t move more than 1 inch from side to side.

Always register new child safety seats with the manufacturer. This will keep you updated on recalls and important brand news.

Always match car seat harnesses to their designated slots, as shown in your car seat’s manual.

Always use the top tether when securing a front-facing car seat.

Always buckle up with your kids. It sets a good example and keeps you safe too.

Never let your kids ride in the car without a safety restraint.

Never let your kids ride in another vehicle without the right safety restraints.

Never secure a rear-facing car seat in the front passenger seat.

Never buckle in your child while they’re wearing a bulky coat or outerwear. Thick outerwear can make the seat less effective. You can drape the coat over your child after they are strapped in.

Never let kids under 13 ride in the front seat. Avoid letting them ride in vehicles with no back seat or active front-seat passenger airbags.

Never use an expired, recalled, or damaged car seat.

If you have a car seat in your vehicle, visit a Certified Child Passenger Safety Technician in your community to double-check that it’s properly installed. Find a car seat inspection station in your area or learn how to become a licensed car seat technician.

Car crash stats methodology

The SafeWise team evaluated car crash data from the National Highway Transportation Safety Administration to determine which states in the country had the highest and lowest numbers of child car crash fatalities per 100,000 children. We also examined state laws on child safety and pediatric recommendations for the best safety practices for children up to 13 years old.
