When people hear that a car and an 18-wheeler collided during a lane change, the first question on their mind is usually, Who moved over, and why did they do it when it wasn’t safe? But the harder truth is that we don’t know yet, and that missing piece makes all the difference.

According to the report, one of the vehicles changed lanes, but it doesn’t say which one. That’s a major gap in the facts. If the car moved into the truck’s lane, we’d want to know whether the driver had enough space, or if the truck was speeding or lingering in a blind spot. If the truck changed lanes, we’d want to know whether the driver checked their mirrors, used their turn signal or simply expected smaller vehicles to get out of the way. Either scenario raises very different legal questions, and very different responsibilities.

Without specifics, it’s impossible to say who’s at fault. But that doesn’t mean investigators are out of options. Far from it.

The truth is likely hiding in the data. Modern 18-wheelers carry electronic control modules (ECMs) that log key vehicle functions — speed, braking, steering and more — before, during and after a crash. If the truck had in-cab cameras, those may show what the driver was seeing and doing at the time of impact. Cell phone records can answer whether anyone was distracted. And physical evidence — like the location of the damage or marks on the roadway — can help reconstruct exactly how this happened.

I’ve handled crashes that looked ambiguous at first glance, where everyone assumed fault would be hard to pin down. But once the data was collected and examined, the facts became clear. That’s why a proper investigation is so important—it’s the only way to move past assumptions and get to the truth.

Key Takeaways:

• The report says one vehicle changed lanes, but doesn’t specify which; an essential detail for understanding fault.
• Critical evidence may include ECM data, in-cab video, phone records and physical damage analysis.
• The truck’s black box can reveal speed, braking and steering data that may clarify who caused the collision.
• Without a thorough investigation, it’s impossible to hold the right party accountable.
• Ambiguous crashes often become clear once all the evidence is in, but only if someone takes the time to look.
