Why Are Tractor-Trailer Crashes More Complex to Investigate?
The size and weight difference between a tractor-trailer and a passenger vehicle plays a significant role in how a crash unfolds, leaving the smaller vehicle with more damage relative to its size. Investigators typically examine both vehicles closely to understand how the disparity affected the outcome.
Tractor-trailers also carry additional data through onboard systems that can record speed, braking, and other details leading up to a crash. This information becomes an important part of piecing together exactly what happened in the moments beforehand.
Overnight crashes on interstates add another layer of difficulty, since fewer witnesses are typically around and reduced visibility can complicate initial assessments. Investigators rely more heavily on physical evidence and vehicle data in these cases to reconstruct an accurate account of the crash.
