The limiting effects of exemptions to the coverage of child restraint laws were estimated by determining the extent to which the laws would have applied to child motor vehicle occupants, ages 0-5 years, killed before the laws were passed (1976-80). The 50 state laws would have exempted about 39 per cent of child motor vehicle occupants less than 6 years of age killed in the years immediately preceding enactment of the laws. Of those children killed in pre-law years who were within the age limits set by the subsequent state laws, about 21 per cent would not have been covered. The gaps in the laws are unnecessary, and proper amendments based on these data can save lives.
通过确定儿童约束法在其通过之前（1976 - 1980年）对0至5岁在机动车事故中死亡儿童的适用范围，来估计该法律豁免条款的限制作用。这50个州的法律会使在法律颁布前几年内死亡的6岁以下儿童机动车乘客中约39%获得豁免。在法律颁布前几年内死亡且处于后续州法律设定年龄限制范围内的儿童中，约21%本不应被涵盖在内。法律中的这些漏洞是不必要的，基于这些数据进行适当修正可挽救生命。
