Commentary

The first thing I think about in a crash where an 18-wheeler bursts into flames is not just what caused the wreck—it’s what caused the fire. Most people assume a crash is a crash, but a fire makes it something different. When a commercial vehicle catches fire after an impact, that usually points to a second layer of legal questions beyond what happened on the road.

One reason I say that is because most vehicles, even big ones, don’t just catch fire without something going very wrong. That could mean a defect in how the vehicle was designed. It could mean that parts of the truck, like the fuel system or battery, weren’t protected the way they should’ve been. If that’s the case, the fire itself may have been preventable—and that makes it a legal issue, not just a mechanical one.

Something else worth pointing out is that truck fuel tanks are often mounted in places where they’re exposed—what we call "side-saddle" tanks. That’s a risk that shows up in crashes like these. I’ve litigated cases where just a small shift in how the vehicle was built would have made the difference between a fire and no fire. But the only way to find that out is to examine the truck itself. That takes experts, tools, and time—things that aren't always part of the basic crash investigation.

So far, there’s no word on what caused the truck to lose control. But even without that answer, I’d argue that a proper investigation has to look beyond the road. What was going on with the truck’s equipment? Was it well-maintained? Were the tanks intact before the crash? Was there any damage that should’ve kept the vehicle out of service?

All of those questions have legal weight. They speak to whether the company that owned the truck did what the law expects them to do—keep the vehicle in safe condition and put a safe piece of equipment on the road. And when someone dies in a crash that involves fire, these questions only grow more important.In a crash like this, it’s not enough to ask what led the truck to hit a barrier. You also have to ask what caused the fire. That part of the case may uncover whether the vehicle had design problems or whether it was in poor condition when it hit the road. These aren’t just side issues—they’re central to figuring out who, if anyone, failed to live up to their legal duties.
