When a commercial truck sideswipes a car during a lane change, it may seem like a clear-cut case: the driver didn’t check their blind spot, or they changed lanes when it wasn’t safe. But in commercial vehicle crashes like this one, the most important question isn’t just what happened—it’s why.

Why did the driver of a fully loaded 18-wheeler make an unsafe lane change in the first place? Were they distracted, fatigued, or rushing to stay on schedule? Were they properly trained and qualified? Was the company that put them on the road even monitoring how safely they were driving?

In my experience, those “why” questions almost always lead to bigger answers. I’ve seen companies that pressure drivers with impossible deadlines, cut corners on training, or fail to use basic tools like in-cab cameras and driver safety monitoring. And when a company treats safety as optional—or simply doesn’t pay attention—drivers are more likely to make dangerous decisions behind the wheel.

It’s good that authorities are citing the truck driver for an unsafe lane change. But that’s just one piece of the puzzle. A proper investigation should look into driver logs, dispatch timelines, training records, and internal communications. Because if this wreck happened under pressure from poor company practices, that’s something the citation alone won’t uncover—but the victims still deserve answers.

Key Takeaways

• Unsafe lane changes by truck drivers often stem from pressure, distraction, or lack of training.
• It's not enough to know what happened—a full investigation should uncover why it happened.
• Companies that fail to train or monitor their drivers can be directly responsible for crashes.
• Driver citations are only one step; deeper review of employer practices is critical.
• True accountability means looking beyond the driver to the system that enabled the mistake.
