When a commercial truck shifts into another lane without warning, the results can be catastrophic. The causes are rarely straightforward. A truck driver may misjudge a blind spot, drive beyond safe hours, carry unstable cargo that shifts weight unpredictably, or operate with poorly maintained mirrors and sensors. Determining exactly why a lane change collision happened requires careful examination of multiple layers of evidence.
The challenge is that critical information begins disappearing almost immediately after the crash. Skid marks are covered by new traffic. Surveillance cameras in nearby businesses often erase or overwrite footage within days. Most commercial trucks have an Electronic Control Module, or black box, that records speed, braking, steering input, and throttle data before and during the impact. Once the truck returns to service, that data can be permanently overwritten. Federal Motor Carrier Safety Administration rules also allow trucking companies to discard driver logs, maintenance records, and training files after limited retention periods, in some cases only six months. Without prompt legal action, valuable records that explain the cause of the crash can be lost forever.
Experienced Truck Accident Attorneys often work with accident reconstruction specialists to collect and analyze this evidence. Black box data may reveal that the driver failed to signal a merge or was traveling too fast for road conditions. Driver qualification files can uncover gaps in blind spot safety training. Cargo loading reports sometimes show that poorly balanced freight made the truck unstable during the lane change. These technical details help explain what went wrong.
At the same time, evidence must also show how the collision affected the people involved. Immediate medical evaluations connect injuries to the side-impact forces typical in lane change crashes. Lost wage documentation and vehicle damage assessments reveal the economic consequences for families who are suddenly left without transportation or income. Together, these elements form the foundation of personal injury cases involving commercial trucks.
A personal injury lawyer can issue preservation notices to stop companies from discarding important data. They can also work with investigators to locate nearby surveillance footage and speak with witnesses before memories fade. Without these steps, proving negligence in a lane change truck accident can become significantly more difficult.
