Motor vehicle crashes are a leading cause of death among those aged 1-54 in the U.S.1 More than 2.2 million adult drivers and passengers were treated in emergency departments as the result of being injured in motor vehicle crashes in 2012.1 Adult seat belt use is the most effective way to save lives and reduce injuries in crashes.2 Yet millions of adults do not wear their seat belts on every trip.3
How big is the problem of crash-related injuries and death?
Motor vehicle crashes are a major public health problem.
- Non-fatal crash injuries resulted in more than $50 billion in lifetime medical and work loss costs in 2012.4
- Motor vehicle crashes are the leading cause of death among teens.1
- Young adults (18-24) have the highest crash-related injury rates of all adults.5
What is the impact of seat belt use?
- Seat belts reduce serious crash-related injuries and deaths by about half.6
- Air bags provide added protection but are not a substitute for seat belts. Air bags plus seat belts provide the greatest protection for adults.7
Who is least likely to wear a seat belt?
- Of the teens (aged 13-20 years) that died in crashes in 2012, approximately 55% of them were not wearing a seat belt at the time of the crash.8
- Adults age 18-34 are less likely to wear seat belts than adults age 35 or older. (CDC, 2010, unpublished data)
- Men are 10% less likely to wear seat belts than women. (CDC, 2010, unpublished data)
- Adults who live in rural areas are 10% less likely to wear seat belts (78% use) than adults who live in urban and suburban areas (87% use). (CDC, 2010, unpublished data)
- Seat belt use is lower in states with secondary enforcement seat belt laws or no seat belt laws (80%) compared to states with primary enforcement laws (89%).3
- Rear-seat motor vehicle passengers are less likely than front-seat passengers to wear a seat belt, making them more likely to injure themselves and other passengers in a crash.9
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.
- Consider proven strategies for increasing seat belt use and reducing child motor vehicle injuries and deaths, which include:10
- 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 car, 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 professionals can:
- Remind patients about the importance of seat belt use.
- Encourage patients to make wearing a seat belt a habit.
- Wear seat belts themselves and encourage their colleagues to do the same.
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.
- Have all children age 12 and under sit properly buckled in the back seat.
- Remember to 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.

- Use a seat belt on every trip, no matter how short.
- Require everyone in the car to buckle up, including those in the back seat.
a State primary and secondary seat belt laws vary by whether driver and front seat passengers are required to be buckled or whether drivers and all passengers (i.e., front and rear seats) 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.
