Janesville, WI — January 10, 2025, one person was killed in a truck accident at about noon on Interstate 39.
Authorities said a semi-truck crashed into a Rock County Highway Department snowplow that had been clearing snow from the shoulder near the median. The collision forced the truck to jackknife, blocking the southbound lanes of the highway.
The truck’s driver, whose name has not been released at this time, was pronounced dead at the scene, according to authorities.
The snowplow driver was not injured, authorities said.
The crash is still being investigated.

A crash like this one highlights the unique dangers that arise when large vehicles operate in close proximity on snowy highways. The loss of the truck driver is a reminder of how critical it is for all parties — drivers, road crews and policymakers — to prioritize safety in these challenging conditions.
The first question that comes to mind is how the semi-truck collided with the snowplow. Snowplows, by their nature, often travel at slower speeds and may obstruct part of the roadway as they clear snow. Was the truck driver aware of the plow’s presence and properly adjusting his speed and position? Visibility is often limited in snow-clearing operations due to blowing snow and poor weather conditions, making it harder for drivers to see and react to road crews. Investigators should explore whether the snowplow was adequately marked with lights or reflective materials to ensure it was visible.
Another important aspect to examine is whether road conditions contributed to the crash. Snow and ice can significantly reduce traction and make stopping distances much longer, particularly for semi-trucks carrying heavy loads. Was the truck traveling at a speed appropriate for the conditions? Investigators should also look into whether the truck’s braking and tire systems were in good condition, as these are critical for safe operation in winter weather.
The location of the snowplow’s operation is also worth scrutiny. Was the plow positioned in a way that allowed enough room for other vehicles to pass safely? While snowplows are essential for clearing highways, their work can inadvertently create hazards if they’re not operating in well-planned areas or if other drivers aren’t adequately warned. If the snowplow’s placement played a role, it might point to the need for changes in how and where snow-clearing operations are conducted.
Finally, the trucking company’s policies and practices should not be overlooked. Was the driver operating under tight schedules or conditions that might have pressured them to maintain higher speeds despite the weather? Did the company provide adequate training for winter driving and ensure their vehicles were prepared for icy conditions? These systemic factors often contribute to crashes involving commercial trucks.
This crash underscores the inherent risks of winter highway operations and the need for both drivers and road crews to exercise extra caution during snow-clearing activities. As the investigation unfolds, I hope it provides a clear understanding of what led to this tragic event, not only for the truck driver’s loved ones but also for the broader community. Learning from this crash can inform improvements in winter road safety and help prevent similar losses in the future.
