The week of Nov. 8 was among the most dangerous times of the year for folks traveling Wisconsin's roads and highways as white-tailed deer, consumed with their annual mating season, increasingly ran into traffic.
In 2017, Nov. 8 was the peak day for vehicle vs. deer crashes, with 213 across the state, according to a Milwaukee Journal Sentinel analysis of Wisconsin Department of Transportation data. The year before, the peak was Nov. 10.
While the number of crashes peaks during that time of year, no day is safe: For the second straight year, not a single day passed in 2017 without a motorist striking a deer somewhere in Wisconsin, the DOT data shows.
The lowest number of deer crashes was on New Year's Day, when only seven deer crashes occurred in the state.
From the forested north to the densely populated south and from Lake Michigan in the east to the Mississippi River in the west, 19,899 vehicles crashed into deer on Wisconsin roads and highways last year.
During the past five years, the number of deer crashes in Wisconsin has remained fairly steady between 18,300 and 20,400, according to state DOT numbers.
Most of the deer crashes involve damage to vehicles, but some have resulted in people dying or being injured.
In 2017, nine people were killed and 604 were injured in crashes with deer.
Motorcyclists are particularly vulnerable. Of the nine people killed in 2017 deer crashes, six were motorcyclists. All of the 11 people killed in deer crashes in 2016 were motorcyclists.
Dane County had the most deer crashes in 2017 at 934, followed by Waukesha County at 855 and Manitowoc County at 784.
Accident Costs Are Rising
Beyond the human toll, the crashes are taking an increasing financial toll.
Cars are increasingly likely to have safety technology that helps reduce death or injury for humans. But all that technology also makes repairing deer collisions more complicated and costly.
