BLACK RIVER FALLS, Wis. – A tractor-trailer driver was pronounced dead following a rollover crash on Interstate 94 in Jackson County on Saturday afternoon, according to the Wisconsin State Patrol. The incident, which occurred on the westbound lanes near Black River Falls, has prompted a multi-agency investigation into the potential involvement of a second commercial vehicle.
The crash took place at approximately 12:27 p.m. near Mile Marker 115.5. Preliminary reports from the Wisconsin State Patrol indicate that the tractor-trailer veered off the roadway, rolled over into a ditch, and struck several trees. Authorities confirmed that the driver did not survive the injuries sustained in the collision.
Investigators are currently focusing on the role of a second commercial motor vehicle that may have contributed to the accident. According to law enforcement officials, this second vehicle did not stop at the scene but was subsequently located near Menomonie. The Jackson County Sheriff’s Department assisted State Patrol troopers at the crash site as evidence was collected.
Investigative Outlook
The focus of the inquiry now shifts to forensic collision reconstruction to determine if the second vehicle’s maneuvers directly precipitated the rollover. In complex commercial vehicle investigations, authorities typically rely on electronic control module (ECM) data, dashcam footage, and physical roadway evidence to establish causation. As the investigation remains active, the specific degree of involvement of the second driver is still under review, and authorities have not yet announced whether citations or criminal charges regarding the failure to stop will be filed.
