Are Booster Seats More Effective than Child Safety Seats or Seat Belts at Reducing Traffic Fatalities among Children?

Abstract

In an effort to increase booster seat use among children, the National Highway Traffic Safety Administration is encouraging state legislators to promote stricter booster seat laws, yet there is a paucity of information on booster seat efficacy relative to other forms of restraint. Using data from the Fatality Analysis Reporting System for the period 2008-16, the current study examines the effectiveness of booster seats relative to child safety seats and adult seat belts. For children two to five years of age, we find some evidence to suggest that booster seats are the least effective form of restraint. For children six to nine years of age, all three forms of restraint appear equally effective.
