Currently, 17 states mandate the daytime use of motorcycle headlights. The purpose of these laws is to make the motorcyclists more conspicuous and reduce the number of daytime multi-vehicle collisions. The effectiveness of the laws is examined by comparing the proportion of daytime fatal, front, and side-angle collisions between states with and without such laws. The comparison is based on all motorcycle fatalities recorded by NHTSA for the years 1975-80. The analysis shows no statistically significant difference between states with and without such laws, suggesting that daytime headlight laws are ineffective. Several explanations of this negative finding are explored.
目前，有17个州规定摩托车在白天必须使用前灯。这些法律的目的是让骑摩托车的人更醒目，减少白天多车相撞事故的数量。通过比较有此类法律和没有此类法律的州之间白天致命、正面和侧面碰撞事故的比例，来检验这些法律的有效性。该比较基于美国国家公路交通安全管理局（NHTSA）记录的1975年至1980年期间所有摩托车死亡事故。分析表明，有此类法律和没有此类法律的州之间在统计上没有显著差异，这表明白天前灯法律无效。本文探讨了这一负面结果的几种解释。
