Kansas City, MO — June 17, 2025, One person was injured following an 18-wheeler accident that occurred around 4:00 A.M. on US 71.
According to reports, an 18-wheeler was traveling south on US Highway 71 near 75th Street when it drifted lanes and struck a Ford Mustang. The impact caused the 18-wheeler to strike some cable barriers and overturn.
When first responders arrived on the scene they found the semi driver critically injured and transported them to the hospital where they are reported to be in stable condition. No one else was injured in the crash.
Commentary by Attorney Michael Grossman
When an 18-wheeler drifts out of its lane and hits a passenger vehicle, the natural question is: Why did the driver lose control? That’s the core issue in this crash on U.S. Highway 71 near 75th Street, where a southbound semi drifted over and struck a Ford Mustang before hitting the cable barriers and overturning.
At this point, we know the truck driver was critically injured and taken to the hospital, and that no one else was hurt. But the circumstances behind the lane drift haven’t been explained—and that’s where the investigation needs to start.
Lane Drift Crashes Are Rarely Random
An 18-wheeler doesn’t just drift out of its lane without a reason. In my experience, there are usually a handful of causes worth investigating: distraction, fatigue, medical episodes, mechanical failures, or overcorrection in response to traffic. Each one carries a different legal and operational implication.
For instance, if the truck driver was on a cell phone, that’s a problem not only for the driver, but possibly for the company if they didn’t enforce rules against it. If the driver was fatigued or had exceeded the number of allowable driving hours, that could point to hours-of-service violations. And if something failed on the truck—steering, suspension, tires—then the issue might trace back to poor maintenance.
These aren’t theoretical possibilities. I once handled a case where a truck drifted over and sideswiped a vehicle. The driver claimed he had a “momentary lapse,” but his logs and dispatch records showed he’d been on the road well beyond his legal hours. It wasn’t just a mistake—it was a predictable outcome of being pushed too hard by his employer.
The Role of Technology and Evidence
Most commercial trucks today carry valuable electronic evidence that can shed light on what happened. Engine control modules (ECMs), dash cams, and GPS logs can provide minute-by-minute insights into speed, steering, and driver activity. If those systems were in place here, they could help determine whether the truck driver reacted too late—or didn’t react at all.
It’s also worth noting that the truck overturned after hitting cable barriers. That suggests the truck wasn’t just drifting—it was still under momentum after the impact, which may speak to the driver’s speed or reaction time.
Key Takeaways
- The cause of the lane drift that led to the collision has not yet been identified.
- Common causes of lane drift include distraction, fatigue, mechanical failure, or improper driving behavior.
- ECM data, dash cams, and driver logs can offer vital clues about what led to the crash.
- The fact that the truck struck barriers and overturned points to continued momentum and possibly delayed reaction.
- A full investigation is needed to determine what caused the lane departure and whether it could have been prevented.
