How big is the problem of crash-related injuries and deaths to drivers and passengers?

Motor vehicle crashes are a leading cause of death among people aged 1-54 in the United States.1 Most crash-related deaths in the United States occur to drivers and passengers.5

Seat belt use is the most effective way to save lives and reduce injuries in crashes for adults and older children who are big enough for seat belts to fit properly.5 Yet millions do not buckle up on every trip.6

Deaths
  • About 60% of the people who died in motor vehicle crashes in 2021 were drivers and passengers in passenger vehicles.5  That’s more than 26,000 people.
  • More than half (range: 51%-61%) of teens 13-19 years and adults aged 20-54 years who died in crashes in 2021 were not buckled up at the time of the crash.*5
Injuries
  • More than 1.8 million drivers and passengers were treated in an emergency department as the result of being injured in motor vehicle crashes in 2021.1
  • Young adult drivers and passengers aged 18-28 years had the highest crash-related non-fatal injury rates among people of all ages.1
Costs
  • Non-fatal crash injuries to drivers and passengers resulted in over $220 billion in lifetime medical, work, and quality of life loss costs in 2021.7

Who is least likely to wear a seat belt?
Age
  • Young adults (age 18-24) are less likely to wear seat belts than those in older age groups.8
Gender
  • Men are less likely to wear seat belts than women.8
Metropolitan Status
  • Adults who live in non-metropolitan areas are less likely to wear seat belts than adults who live in metropolitan areas.8
State Laws
  • Seat belt use is lower in states with secondary enforcement seat belt laws or no seat belt laws (90% in 2022) compared to states with primary enforcement laws (92% in 2022).9
Seating Position in Vehicle

Rear-seat motor vehicle passengers [PDF – 4 pages] are less likely than front-seat passengers to wear a seat belt,10 making them more likely to injure themselves and drivers or other passengers in a crash.11

What is the impact of seat belt use?

    Seat belts reduce serious crash-related injuries and deaths by about half.12

  • Seat belts saved almost 15,000 lives in 2017.5
  • Air bags provide added protection but are not a substitute for seat belts. Air bags plus seat belts provide the greatest protection for adults.13
Primary enforcement laws make a difference

Research shows, primary enforcement seat belt laws make a big difference in getting more people to buckle up and reducing the risk of dying in a crash.8,14 Observed seat belt use in 2022 was 92% in states with primary enforcement laws and 90% in states with secondary enforcement laws or no seat belt laws.9

A primary enforcement seat belt law means a police officer can pull a vehicle over and issue a ticket just because a driver or passenger covered by the law is not wearing a seat belt. A secondary enforcement law only allows a police officer to issue a ticket for someone not wearing a seat belt if the driver has been pulled over for some other offense. State primary and secondary seat belt laws vary by whether drivers and all passengers (i.e., front and rear seats) or drivers and only front seat passengers are required to be buckled. These requirements may also vary depending on the age of the passenger. For information on laws in each state, check with the Insurance Institute for Highway Safety at http://www.iihs.org. As of September 2023, 29 states did not have a primary enforcement law covering all seating positions for adults (ages 18+ years).15

What can be done to increase seat belt use among adults?

When it comes to increasing seat belt use, individuals, government, and health professionals can help promote safety.

Building icon

States can:

  • Consider proven strategies for increasing seat belt use and reducing child motor vehicle injuries and deaths, which include:14,16
    • Primary enforcement seat belt laws, which have been shown to increase use and reduce deaths compared with secondary enforcement laws.
    • Seat belt laws that apply to everyone in the vehicle, not just those in the front seat.
    • Fines for not wearing a seat belt that are high enough to be effective.
  • Make sure that police and state troopers enforce all seat belt laws.
  • Support seat belt laws with visible police presence and awareness campaigns for the public.
  • Educate the public to make seat belt use a social norm.
Health care professionals icon

Health professionals can:

  • Remind patients about the importance of seat belt use on all trips and in all seats.
  • Encourage patients to make wearing a seat belt a habit.
  • Wear seat belts themselves and encourage their colleagues to do the same.
Parents icon

Parents and caregivers can:

  • Use a seat belt on every trip, no matter how short. This sets a good example.
  • Make sure children are properly buckled up in a car seat, booster seat, or seat belt, whichever is appropriate for their age, height, and weight.
  • Properly buckle all children ages 12 and under in the back seat.
  • Never place a rear-facing child safety seat in front of an air bag.
  • Properly buckle children in the middle back seat when possible because it is the safest spot in the vehicle.
Everyone icon

Everyone can:

  • Use a seat belt in the front and back seats on every trip, no matter how short.
  • Require everyone in the car to buckle up, including those in the back seat.
