The authors found good evidence that community-based programs, such as laws, car seat distribution programs, and public service announcements, improve the use of child safety seats and seat belts. They also found that targeted counseling for people with a history of alcohol problems or drunk driving can decrease future accidents. However, they did not find evidence to show that counseling about child safety seats, seat belts, and drunk driving during doctors' visits provides additional benefit beyond other programs that promote driving safety, or that such counseling improves age- and weight-appropriate use of child safety seats. The authors found no good studies that addressed the harms of counseling, but they believe that counseling is unlikely to be harmful.
