One hundred and fifty-one automobile collision reports involving over 850 persons were examined;​ in each case one or more of the passengers was a child under the age of 5. Emphasis was placed on post-1966 vehicles, on collisions involving a restrained driver (who would more likely be carrying restrained children), and on cases in which the severity of the crash and the severity of the injuries seemed inconsistent.

Safety standards for children's car seats were examined and assessed, parental attitudes towards the devices were reported, and current restraints in use in North America evaluated.
