Understanding Safety Ratings

Safety ratings are determined through a combination of crash testing, ease of use evaluation, and fit-to-vehicle assessment. Here's what parents should look for:

  • Five-Star Rating System: NHTSA's evaluation of ease of use and installation features
  • Additional Testing: Many manufacturers conduct tests beyond federal requirements
  • Consumer Reports: Independent testing and comparative analysis
  • Real-World Performance: Crash statistics and user experiences
