Use of Safety Belts: Laws Mandating Use

Safety belt laws mandate the use of safety belts by motor vehicle occupants. All current U.S. laws cover front seat occupants. Other requirements, such as rear seat coverage, fines, affected age groups, type of enforcement, and exempted vehicles and drivers vary by state.

Summary of Task Force Recommendations and Findings

The Community Preventive Services Task Force  recommends safety belt laws as a strategy based on strong evidence of their effectiveness in increasing safety belt use and reducing fatal and non-fatal injuries among adolescents and adults.

Task Force Finding

Results from the Systematic Review

Thirty-three studies qualified for the systematic review.

  • Fatal injuries: median decrease of 9% (interquartile interval: 2% to 18% decrease; 6 studies)
  • Nonfatal injuries: median decrease of 2% (interquartile interval: 15% decrease to 11% increase; 6 studies)
  • Fatal and nonfatal injuries combined: median decrease of 8% (interquartile interval: 3% to 20% decrease; 9 studies)
  • Observed safety belt use: median increase of 33 percentage points (interquartile interval: 20 to 36 percentage points; 10 studies)
  • Police-reported safety belt use: increase of 26 percentage points (2 studies)
  • Self-reported safety belt use: median increase of 16 percentage points (interquartile interval: 13 to 19 percentage points; 4 studies)

These results are based on a systematic review of all available studies led by scientists from CDC’s Division of Unintentional Injury Prevention with input from a team of specialists in systematic review methods and experts in research, practice and policy related to increasing safety belt use.
