Commentary by Attorney Michael Grossman

When two commercial trucks collide—especially a septic truck and an 18-wheeler—the physical damage alone can be extensive. But the legal analysis goes beyond twisted metal. It’s about understanding which driver made the wrong move, and whether either had the chance to prevent the outcome, even after the first mistake was made.

At this point, it’s not clear what caused the collision. Was one truck stopped or merging at the exit? Did a lane change go wrong? Was one driver following too closely or not paying attention? The only way to answer those questions is through engine control module (ECM) data, dash cam footage, and in-cab video, if available. That evidence will show what the drivers were doing—how fast they were going, whether they braked, and how much time passed between hazard and impact.

Entrapment cases like this usually involve a high-speed impact or significant structural damage, which often points to one driver either reacting too late or not reacting at all. That opens the door to questions about distraction, fatigue, or even whether one of the trucks was illegally parked or improperly positioned at or near the off-ramp.

Both vehicles being commercial also brings both companies into focus. Did they equip their trucks with the safety tools available—dash cams, proximity sensors, blind spot mirrors? Were their drivers adequately trained to operate in merging or exit-lane traffic at highway speeds? These are not afterthoughts; they often turn out to be the difference between a crash that was preventable and one that wasn’t.

In my experience, crashes between two trucks are rarely the result of a single mistake. They’re usually the final link in a chain of decisions—made by drivers, dispatchers, and management—that didn’t account for the conditions on the road that day.


Key Takeaways:

  • The cause of the crash is still unclear, but ECM data and dash cam footage will be crucial to determining fault.
  • Entrapment suggests a high-force impact, raising concerns about driver reaction time and vehicle positioning.
  • Factors like distraction, fatigue, and improper merging may have contributed and must be investigated.
  • Both companies’ training, safety equipment, and oversight practices should be examined.
  • Responsibility in dual-truck crashes often lies in a series of preventable missteps—not just a single bad move.
