When people read about a crash between a car and an 18-wheeler on a major highway like I-35, the first thing they usually want to know is: How exactly did this happen? Was the truck changing lanes? Was it stopped in the roadway? Did it merge into the Mustang’s path? The report doesn’t say, and until we have that information, we can’t begin to sort out who’s responsible.
The fact that authorities haven’t identified the semi-truck yet only adds to the list of unanswered questions. Does that mean the truck kept going after the crash? Was it even aware of the collision? Or was the truck parked or disabled in a dangerous spot? Each of those scenarios raises different legal and investigative concerns.
Depending on whether the truck was moving or stopped, different questions arise. If it was moving, we’d want to know what the driver was doing just before the crash. Was he distracted? On his phone? Was there dash cam or in-cab camera footage that might show whether he made an unsafe maneuver? If the truck was stopped, then it’s critical to determine why. Was it disabled without hazard lights or warning triangles? Was it parked illegally?
I’ve handled plenty of cases where a trucking company failed to maintain its vehicles, leading to breakdowns that exposed unsuspecting motorists to serious danger. I’ve also seen cases where drivers lost control due to fatigue, speeding or simple inattention. But we can’t guess. That’s why it’s so important to secure engine control module (ECM) data, driver logs and call records, evidence that can help clarify what role, if any, the truck played in causing the crash.
We also have to consider the possibility that the truck wasn’t directly responsible. For instance, if the Mustang driver lost control for reasons unrelated to the truck — say, mechanical failure or impairment — then the legal picture would look very different. But again, we don’t yet know.
The key is a full investigation. That includes locating the truck involved (if it hasn’t been identified yet), preserving digital evidence from both vehicles, and interviewing any witnesses who saw how this all unfolded.
Key Takeaways:
- It’s not clear yet how the truck was involved or whether it was moving or stopped at the time of the crash.
- Identifying the truck and securing ECM, dash cam and cell phone data are essential first steps.
- Depending on the truck’s role, legal responsibility could lie with the driver, the trucking company or neither.
- A full investigation is needed to uncover the facts and hold the right parties accountable.
