Abstract

Abstract Many states in the United States have passed the primary enforcement seat-belt law. Though there is strong evidence from previous studies that enhanced seat-belt enforcement interventions can substantially increase seat-belt use, thereby reducing fatalities. It is still necessary to evaluate the long-term effects of implementing the primary seat-belt law. In this study, changes in fatalities over time after the primary seat-belt law enactment are investigated using before-and-after study with the comparison group methods for fatality modification factors (FMFs). This study confirms that the number of adult fatalities without seat-belt has significantly decreased by 17.29%. Another key finding is that the fatality rates in states with a higher maximum fine amount are significantly lower than those with a lower one, however, the decrease in fatality trend is not as effective above about $100 fine. Implementing the primary seat-belt law is significantly effective in reducing fatalities without seat-belt in the long-term. Meanwhile, the relationship between fatalities reduction and the maximum fine amount is not positively linear related. It is imperative that states with the secondary seat-belt laws must reform their seat-belt laws to the primary seat-belt law. An appropriate fine amount can be determined to maximize the effectiveness of the primary seat-belt law.

主安全带法的长期安全性评价
摘要:美国许多州都通过了强制性安全带法。虽然以前的研究有强有力的证据表明,加强安全带执法干预可以大大增加安全带的使用,从而减少死亡人数。仍然有必要评估实施初级安全带法的长期影响。在本研究中,使用死亡修正因素(FMFs)的前后比较组方法,调查了主要安全带法律颁布后死亡人数随时间的变化。该研究证实,没有安全带的成人死亡人数显著下降了17.29%。另一个重要发现是,在最高罚款金额较高的州,死亡率明显低于最高罚款金额较低的州,但在100美元左右的罚款中,死亡率下降趋势并不有效。从长远来看,实施主要安全带法在减少无安全带死亡事故方面显着有效。同时,死亡人数减少与最高罚款金额之间不存在正线性关系。有二级安全带法的州必须将其安全带法改革为一级安全带法。可以确定适当的罚款数额,以最大限度地发挥主要安全带法的效力。
