Multiple Wisconsin State Patrol WSP troopers and motor carrier inspectors responded to a series of crashes involving approximately 20 vehicles and four semi-tractor trailer units Sunday.
The crashes occurred on I-39/90 north bound at Mile Marker 167 (north of Janesville) at approximately 1:50 p.m. Throughout the entire incident, two, non-life threatening injuries were reported by WSP.
State Patrol Sgt. Michael Vasquez told Adams Publishing Group that slippery road conditions and motorists driving too fast for those conditions were the primary factors that lead to multiple vehicle crashes.
The preliminary WSP investigation indicates the chain of events began as a tow truck operator was attempting to clear the roadway from an initial crash.
