Statistics Enumerate Risk of Being Unprepared for Winter
Being better prepared for winter not only makes sense from the standpoint of vehicle uptime, but also accident avoidance.
According to the Federal Highway Administration, an analysis of 10-year averages from 2007 to 2016 shows that there were about 5.9 million vehicle crashes each year. Approximately 21% of those crashes — 1,235,145 — are weather-related. And of those 1.2 million weather-related crashes:
18% or nearly 220,000 occur during snow or sleet conditions, resulting in 54,839 people injured and 688 people killed;
13% or 156,000 occur on icy pavement, resulting in 41,860 people injured and 521 killed;
And 16% or 186,000 occur on snowy or slushy pavement resulting in 42,036 injuries and 496 fatalities.
A study by University of Georgia researchers Alan Black and Thomas Mote published in the Journal of Transport Geography in 2015 examined federal motor vehicle crash data from 1975 to 2011 and compared the crash data to meteorological data from 1996 to 2010. The comparisons helped to determine how the expected number of deaths in 13 U.S. cities involving winter precipitation compared to the actual numbers.
Among their findings, Black and Mote determined that heavy snowfall regions in northern California, Nevada, and Arizona, the Upper Peninsula in Michigan, and near lakes Erie and Ontario in Upstate New York experienced higher than expected fatalities.
“In general, (the study found) crash risk increases 19% during winter weather,” Black said.
Black, who now serves as an assistant professor at Southern Illinois University’s Department of Geography, says that the risk of crash is greater regardless of vehicle type or size.
Through their comparison, they also determined that the U.S. National Weather Service significantly underreports the threat posed by winter weather in its weather injuries and fatality report.
Among some of their other findings, Black and Mote note:
In terms of precipitation type, 84% of crashes could be attributed to snowfall, with the remaining 16% attributed to sleet or freezing rain;
January had the most fatalities and collisions and December the second-most fatalities and crashes;
Only 45% of winter-related fatal accidents occur at night, which the researchers found surprisingly lower than expected since daylight hours are shortest in the winter months. By comparison, 51% of non-winter-related fatal crashes occur at night. Researchers surmised that the higher fatality rate during the day could be attributable to more adults commuting to work regardless of weather.
