Commentary by Attorney Michael Grossman

When I hear about a crash between a box truck and an 18-wheeler, especially one involving a rollover, my first thought isn’t simply about who ran into who. Instead, I think about the complex web of legal issues that can come into play when two commercial vehicles collide.

One of the first questions investigators will need to answer is whether either driver failed to yield the right of way. Determining fault isn’t always as simple as looking at vehicle damage or skid marks at an intersection. Real crash investigations involve gathering much deeper evidence. That includes things like reviewing dashcam footage, obtaining traffic signal data if the intersection had cameras, and checking for possible distractions like cell phone use.

Another important part of this investigation should be looking at both drivers’ hours of service logs and vehicle maintenance records. Fatigue is a major cause of crashes involving commercial vehicles, and poor maintenance can lead to mechanical failures that make collisions more likely. These are not things you can spot just by standing at a crash scene — they require digging into the background of the drivers and the companies that put them on the road.

Additionally, it’s important to consider whether the size and weight of the vehicles, especially an 18-wheeler pulling two trailers, played a role. Handling a double-trailer rig requires specialized skills and proper training. If the driver wasn’t adequately trained or if the load was improperly balanced, those failures could have made the truck harder to control, particularly during turns or emergency maneuvers.

From my experience handling truck accident cases, crashes like this rarely have a single cause. They often involve a combination of driver decisions, company policies, and vehicle conditions. That’s why a proper investigation can’t just look at what happened in the few seconds before the crash — it has to go back days, weeks, or even months to see if warning signs were missed along the way.

At the end of the day, the main thing to remember is that getting to the truth requires more than a quick review at the crash scene. It demands a careful and thorough examination of all the evidence. Otherwise, it’s easy to end up blaming the wrong person or missing who really bears responsibility for what happened.
