A serious multi-vehicle crash involving a semi-truck occurred Wednesday afternoon in Denmark Township, Minnesota, just outside Cottage Grove. The Minnesota State Patrol responded to the scene around 1:50 p.m. at the intersection of Highway 95 and 70th Street. According to preliminary reports, a semi-truck allegedly struck a pickup truck, which then caused a chain reaction involving a third vehicle. Authorities have confirmed that the driver of the pickup truck sustained life-threatening injuries. The cause of the crash remains under investigation.

Whenever a semi-truck is involved in a crash, especially one with multiple vehicles, I think about how crucial it is to determine what actually triggered the sequence of events. In my experience, large commercial vehicle crashes often unfold in a matter of seconds, and the key to understanding them lies in collecting and analyzing every piece of available evidence.

What Actions Happened Before the Collision?

With limited details about how the crash began, it’s important for investigators to determine what actions were taken by each driver. Was the pickup stopped or slowing at an intersection? Was it turning or crossing lanes? At the same time, was the semi-truck following too closely? These are the kinds of situational questions that can’t be answered without a detailed reconstruction of the crash.

Could Fatigue or Distraction Have Played a Role?

While it’s too early to know what led to the initial impact, investigators should consider whether the semi-truck driver was fully alert and attentive at the time of the crash. Fatigue and distraction are well-documented concerns in commercial trucking, and even a brief lapse in concentration can have serious consequences.

What Evidence Should Investigators Review?

To determine how this crash unfolded, investigators should review the semi-truck’s Engine Control Module (ECM) for pre-collision data like speed, braking, and throttle activity. If available, dash cam footage and surveillance video from nearby intersections could offer visual confirmation of vehicle movements. Scene evidence, including skid marks, impact angles, and damage patterns, will help reconstruct the collision. Eyewitness accounts may also help clarify whether one of the vehicles stopped, turned, or changed lanes unexpectedly.

Why Fact-Based Investigation Matters in Semi-Truck Crashes

In my experience handling commercial vehicle cases, I’ve seen how critical it is to avoid speculation when serious injuries are involved. These are often high-stakes situations, and it’s only through a methodical, fact-based investigation that the full story comes to light. Whether the key issue in this crash turns out to be driver error, vehicle condition, or something else entirely, the investigation will provide the answers needed to determine how and why it happened.
