Pediatricians are well acquainted with the fact that accidents are the leading cause of death in children after the first year of life, and that the automobile causes more deaths than all other accidental causes combined. During the last 20 years, while the death rates from infectious diseases and other causes have shown a marked decline, death rates from accidents, in children under 4 years of age, have remained unchanged. It is all too apparent that vigorous action among those providing medical care for children must now be directed to the prevention of accidental death and injury, particularly from the automobile.
