The effectiveness of safety restraints in protecting children from motor vehicle injuries has been well documented,1 prompting all states to require that child passengers ride in appropriate restraints.2 Although the prevalence of child restraint device use has increased following the passage of child restraint device laws, many drivers use restraints incorrectly on their child passengers. For example, in a recent study of child restraint device use, we reported that, although 75% of children were riding in restraints on seat belts, 62.9% of those children were incorrectly restrained.3 In a 1984 study, Cynecki and Goryl4 reported a similar misuse rate of 64.6%.
