Commentary

When a passenger vehicle becomes disabled in the travel lanes of an interstate and is then struck by an 18-wheeler, it's easy to frame the event as an unavoidable consequence of being in the wrong place at the wrong time. But in my experience, particularly with late-night highway crashes involving commercial vehicles, the reality is often more complex. These collisions raise critical questions about visibility, reaction time, and whether the commercial vehicle was being operated in a way that accounted for the conditions on the road.

One of the most pressing issues in this kind of situation is how much time, space, and visibility the truck driver had to recognize the disabled vehicle and respond. At around midnight, visibility is limited, and fatigue can start to set in for drivers on long hauls. That’s why commercial drivers are trained to maintain appropriate following distances and scan the road ahead with particular care during night driving. If the truck was traveling too fast for the conditions or following too closely, the margin for avoiding a disabled vehicle shrinks considerably.

It also matters how the Jetta came to a stop and whether other drivers would reasonably have been able to see it. Was the car in a straightaway or a curve? Was it dark-colored, making it harder to spot under poor lighting? Did the hazard lights come on, or was it left entirely unmarked in a high-speed lane? None of this excuses the dangers of a disabled car in an active lane, but it does help determine whether a professional driver had a meaningful opportunity to avoid the collision.

If the 18-wheeler was being operated under a commercial carrier, then the company’s role also comes into play. Did they provide their driver with the training and tools necessary to recognize and react to sudden hazards at night? Were they monitoring for compliance with hours-of-service rules to ensure the driver wasn’t fatigued? And was the vehicle equipped with functioning headlights, dash cameras, or collision mitigation systems that could shed light on how the crash unfolded?

From where I sit, a fatal crash involving a disabled vehicle and an 18-wheeler deserves a full investigation—not just into the actions of the person who lost control, but into how the truck was operated in the critical seconds that followed. Whether or not the crash could have been avoided depends on many moving parts, and it’s only by examining all of them that we can determine where accountability lies and whether those affected by the wreck receive the clarity and closure they deserve.
