2017 Wisconsin Traffic Crash Facts


The Wisconsin Department of Transportation’s Wisconsin Traffic Crash Facts report serves as a resource for traffic safety professionals and those interested in making Wisconsin’s roadways, sidewalks, and bicycle paths safe for all who travel them. It contains statewide information about traffic crashes and the related behavioral factors.

In 2017, Wisconsin saw 139,870 crashes and 594 people killed in those crashes, many of which could have been prevented by avoiding risky behaviors like impaired driving, speeding, and not wearing a seat belt.

An impaired or speeding driver was involved in 46% of the 539 fatal crashes. Factors can often overlap; both an impaired and speeding driver was a factor in 13% of fatal crashes.
