EFFECTS OF SNOWFALLS ON MOTOR VEHICLE COLLISIONS, INJURIES, AND FATALITIES

This study estimates the effects of snowfalls on U.S. traffic crash rates by linking all recorded fatal crashes (1.4 million) from 1975 to 2000 to daily state weather data. For a subsample including 17 states during the 1990s, the authors also linked all recorded property damage-only crashes and nonfatal injury crashes to daily weather data. The authors investigated the effect of snowfall on crash counts using negative binomial regression. Fixed effects and other controls were included to address potential confounders. The results showed that snow days had fewer fatal crashes than dry days, but more nonfatal-injury crashes and property damage crashes. The first snowy day of the year was substantially more dangerous than other snow days in terms of fatalities, particularly for elderly drivers. These results can be used to help estimate the potential benefits of safety innovations aimed at reducing the injury and property damage toll of weather-related crashes.
