When people read about a crash involving a semi-truck and multiple vehicles, like the one reported on I-25 near Northglenn, one of the first questions they often ask is: What exactly went wrong here? And perhaps more importantly, how do we get answers when the public details are this limited?

At this point, the basic facts raise more questions than they answer. We know a semi-truck and three other vehicles were involved. We also know the truck was leaking fuel afterward and that three people were hospitalized. What we don’t know is what led to the crash or how the truck’s role shaped the outcome. Was the truck moving or stopped at the time? Was it struck by another vehicle or did it strike them? The answers to those questions change everything.

In my experience litigating these kinds of accidents, the first step in getting clarity is preserving physical and electronic evidence. That includes data from the truck’s engine control module (ECM), which tells us key details like speed, braking and throttle use in the seconds leading up to the crash. If the truck had forward- or driver-facing cameras, those recordings could show whether traffic patterns or driver behavior played a role. Cell phone records may also shed light on whether the driver was distracted.

There’s also a practical reason to press for answers now: once cleanup crews tow away the vehicles and the insurance companies begin posturing, the evidence can start to disappear. Even though authorities are investigating, that doesn’t always mean all the relevant questions are being asked, particularly about the trucking company’s role. What was their policy on driver hours? Was this driver properly screened, trained, and rested? Those are not just technicalities; they’re often the difference between a crash that was preventable and one that wasn’t.

We can’t say at this point whether the truck driver caused this crash, contributed to it or was simply caught in the middle. But accountability begins with facts, and those facts live in the data; black boxes, maintenance records, logbooks, and more. Until that information comes to light, speculation isn’t helpful. Evidence is.

Key Takeaways:

• It’s unclear how the crash happened or what role the semi-truck played.
• Electronic data and camera footage from the truck could clarify critical details.
• Cell phone records and driver logs are essential to rule out distraction or fatigue.
• Questions remain about the trucking company’s policies and oversight.
• A thorough investigation must go beyond surface-level reports to find the truth.
