Zador's preceding study estimates a 13 percent reduction in fatal daytime motorcycle crashes for states which enacted daytime headlight-use laws during the late 1960s and early 1970s. This finding is not noteworthy, since prior research using similar data challenges the effectiveness of these laws. The purpose of the following research is to point out major discrepancies between Zador's and Muller's findings and to examine critically key assumptions made by both researchers. New evidence suggests that the effect attributed to headlight-use laws may, indeed, be spurious.
