Use of Child Safety Seats: Laws Mandating Use

Child safety seat laws require children riding in motor vehicles to be restrained in federally approved infant or child safety seats. Requirements vary by state based on a child’s age, weight, height, or a combination of these factors. Enforcement guidelines and penalties also vary, but all such laws allow drivers to be stopped for failing to place children in safety seats as required under the law.

Summary of Task Force Recommendations and Findings

The Community Preventive Services Task Force recommends child safety seat laws based on strong evidence of their effectiveness in increasing child safety seat use.

Task Force Finding

Results from the Systematic Review

Nine studies qualified for the review.

  • Fatal injuries: median decrease of 35% (range: 25% to 57% decrease; 3 studies)
  • Fatal and non fatal injuries combined: median decrease of 17% (range: 11% to 36% decrease; 5 studies)
  • Observed child safety seat use: median increase of 13% (range: 5 to 35 percentage points; 3 studies)
  • Among the studies that evaluated the laws’ effects on injury rates, researchers found no differences in the effect size based on the age of children who were required to be in safety seats.

These results are based on a systematic review of all available studies led by scientists from the Community Guide and 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 child safety seat use.
