Of all fatalities recorded nationally, NHTSA data shows that a third occur at night in unlighted conditions, while a slightly higher percentage happen at night in roadways with at least some lighting. But there are stark differences in individual jurisdictions’ crash statistics, largely reflecting their lighting systems. In Clark County, home to Las Vegas, the City of Lights, just 6 percent of all pedestrian and cyclist traffic deaths over the three-year period occurred in dark, unlit areas. Denver and Minneapolis reported similarly low tallies. The situation is much different in other large counties. Two-thirds of pedestrian and cyclist fatalities in Greenville County, S.C., and 73 percent in Montgomery County, Texas, outside of Houston, occurred in dark, unlit areas.
