When a crash involves a passenger vehicle and an 18-wheeler, and someone doesn’t make it out alive, people naturally want to know—how did these two vehicles end up in each other’s path? Was someone speeding? Did one of them run a stop sign? Did the truck make a wide turn without checking for oncoming traffic? The answers to those questions aren’t available yet, which means the picture we have right now is incomplete.

That may not seem like a big deal to people reading a short news blurb, but from a legal standpoint, it matters a great deal. In fatal truck accidents, the burden is on investigators to go beyond the scene and dig into the conditions that led up to the crash. Did either vehicle have the right of way? Were there visibility issues? Was the truck driver alert and properly rested? Those answers can’t be guessed—they have to come from hard data.

One of the most valuable sources of that data is the truck itself. An engine control module, if preserved, can show whether the driver braked, accelerated, or swerved in the moments before the collision. In-cab cameras, GPS data, and even the trucker’s cell phone records can add layers of clarity that simple witness statements often can't provide.

But technology isn’t the only angle worth exploring. The trucking company’s role may also come into play. Was the driver properly trained on how to approach intersections safely, especially in low-visibility hours? Did the company do its due diligence before sending that driver out on the road? In more than one case I’ve worked on, a fatal crash looked like simple driver error—until we found out the company had cut corners on training or ignored warning signs in the driver’s record.

Until more evidence comes to light, we can’t know what really happened at that intersection or why. But what we do know is that cases like this don’t resolve themselves. It takes a serious, methodical investigation to answer the questions that matter most—not just for the sake of clarity, but for the sake of accountability.

Key Takeaways:

• No clear explanation has been provided for how the crash occurred or who had the right of way.
• Truck black box data, in-cab video, and driver cell records are key to reconstructing events accurately.
• Trucking company training and oversight may be relevant depending on the circumstances of the crash.
• Fatal truck accidents require more than a surface-level investigation to ensure the right parties are held accountable.
