When a passenger vehicle and an 18-wheeler collide, people naturally want to know: What exactly happened here? Who’s responsible? Are we getting the full picture? Those are fair questions, and based on the details released so far about the crash on U.S. Highway 67, there are more questions than answers.

We know that a Lincoln MKX was heading north on FM 1434 and collided with an eastbound semi-truck on Highway 67, causing the Lincoln to overturn. What’s not clear is how that collision occurred. Did one of the vehicles run a stop sign? Was one turning or crossing the highway? Did either driver fail to yield the right of way? Depending on whether the truck or the Lincoln had the right-of-way, entirely different questions about fault come into play.

The real challenge in a case like this is that we can’t rely on assumptions. Trucks are large and dangerous, yes, but that alone doesn’t answer how or why this crash happened. The key to finding out lies in evidence.

For instance, the semi-truck’s engine control module (ECM), sometimes called the “black box,” likely contains hard data on speed, braking and throttle use. That’s not speculation; it’s something we routinely analyze in the cases I work on. If the truck had in-cab cameras, those may show the moments before the crash. And if the truck driver was using a cell phone at the time, that could be determined through call records or data logs.

Even beyond what happened on the road, we have to ask: Was the truck driver properly trained? Did the company follow proper hiring procedures? I’ve handled cases where the driver wasn’t the only one responsible; the company that put him behind the wheel without adequate vetting had even more to answer for. In one recent case, a driver who had already been fired from multiple jobs was allowed to drive again after nothing more than a quick 20-minute test. That’s not diligence. That’s a lawsuit waiting to happen.

Until an independent investigation is done — one that looks at driver records, vehicle data and company policies — there’s no way to know where accountability lies. But that’s exactly why this process matters. Without a full and fair review of the evidence, there’s a risk that crucial facts will be missed and that the wrong people will be blamed, or worse, no one at all.

Key Takeaways:

  • It’s still unclear how the collision between the Lincoln and the semi-truck occurred or which vehicle had the right-of-way.
  • Critical evidence like ECM data, in-cab video and cell phone records can help reconstruct the moments before the crash.
  • Driver history and company hiring practices may also play a role in determining liability.
  • Independent investigation, not assumptions, is the only way to fairly determine fault.
  • Truck accident cases often involve more than just the driver; trucking companies can bear significant responsibility too.
