Commentary by Attorney Michael Grossman
When people read about a crash like this, the first questions are simple and fair: How did this happen? Who made the mistake? Are we being told enough to understand what really went on? Right now, the answers to those questions are missing.
We know a semi-truck and a Ram pickup collided early in the morning on northbound I-25. What we don’t know is why they came together. That gap matters. Until it’s filled, it’s impossible to understand who may be responsible.
It’s not clear which vehicle changed lanes, drifted or failed to see the other. We don’t yet know whether the semi-truck was moving steadily in its lane, slowing or making some kind of maneuver. We also don’t know what the pickup driver saw, or didn’t see, in the moments before impact. At 4:30 a.m., visibility, lighting and driver alertness all become important unanswered questions.
A proper truck crash investigation goes beyond the roadway. One of the first things I would want to know is what the truck’s engine control module shows. That data can tell investigators the truck’s speed, braking and throttle use right before the collision. If the truck has in-cab or outward-facing cameras, those recordings may show lane position, traffic conditions and whether the driver was paying attention.
Another unanswered question is distraction. Was the truck driver using a cell phone? Were there incoming or outgoing calls or data use at the time of the crash? That’s not something police reports usually answer, but phone records can. The same question applies to the pickup driver.
I’d also want to know about the truck driver’s background. Was the driver properly trained? Had there been prior safety issues? Was the driver working within legal hours, or could fatigue have played a role? Those questions aren’t meant to assign blame; they’re meant to find facts. In my experience, crashes often make more sense only after those records are reviewed.
Right now, authorities say the crash is under investigation, which is appropriate. But investigations only work when all available evidence is preserved and examined. Without that, the public is left guessing, and accountability becomes harder to reach.
Key Takeaways
- We don’t yet know how or why the semi-truck and pickup collided.
- Early-morning conditions raise questions about visibility, fatigue and attention.
- Black box data, cameras and phone records are critical to understanding what happened.
- A full investigation looks at driver actions, vehicle data and company practices, not just the crash scene.
