This study estimates the effectiveness of passenger vehicle daytime running lights in reducing two-vehicle opposite direction crashes, pedestrian/bicycle crashes, and motorcycle crashes. The authors chose the generalized simple odds, a conventional statistical technique, to analyze the data. Results based on simple odds indicate that from 1995 to 2001: DRLs reduced opposite direction daytime fatal crashes by 5 percent; DRLs reduced opposite direction/angle daytime non-fatal crashes by 5 percent; DRLs reduced non-motorists, pedestrians and cyclists, daytime fatalities in single-vehicle crashes by 12 percent; and DRLs reduced daytime opposite direction fatal crashes of a passenger vehicle with a motorcycle by 23 percent. Reviewers of this paper required the inclusion of results using the odds ratio technique. The estimated the effect of DRLs are -6.3 percent, -7.9 percent, 3.8 percent, and 26 percent, respectively. None of these results were statistically significant.
