Fatal motorcycle crashes in the United States from 1975 to 1983 were analyzed. In the 14 states that had motorcycle headlight-use laws during the study period, about 600 daytime crashes of the type included in the study were prevented by these laws. This reduction corresponds to a 13 per cent reduction in fatal daytime crashes and to an average reduction of about five fatal crashes per year for each of the 14 states. About 30 states did not have motorcycle daytime headlight laws in effect during the study period. If all of these states had such laws, in an average year, approximately 140 additional fatal motorcycle crashes would have been prevented.
对1975年至1983年美国致命摩托车事故进行了分析。在研究期间有摩托车头灯使用法律的14个州，这些法律预防了约600起本研究涵盖类型的白天事故。这一减少相当于致命白天事故减少了13%，且这14个州平均每年约减少5起致命事故。研究期间约有30个州没有实施摩托车白天头灯法律。如果所有这些州都有此类法律，平均每年大约可额外预防140起致命摩托车事故。
