When I see that someone ran into the back of a stopped semi-truck, the knee-jerk reaction from many people is to blame the driver who rear-ended the truck. But in my experience, that kind of thinking skips over the most important question: Was the truck supposed to be stopped there in the first place?
The report says the truck was stopped in traffic. If that’s accurate, then we need to understand why it was stopped, where it was stopped and how visible it was to approaching drivers. Was this part of a traffic slowdown that affected the whole highway, or was the truck stopped in a lane unexpectedly? Was the truck clearly visible, or was it around a curve, over a hill or in a shaded area that made it harder to see?
I’ve handled cases where trucks were stopped due to mechanical issues but didn’t activate hazard lights or place warning triangles. I’ve also seen trucks at the back of traffic jams with faded or dirty taillights, which made it nearly impossible for a following driver to spot them in time. That’s why evidence like dashcam footage, traffic camera recordings and the truck’s engine control module data matter so much in cases like this.
The truth is, crashes like this are more about timing and visibility than anything else. If the truck was stopped in a way that left the following driver with no time to react, then the responsibility may lie with the truck driver, or even the company that put that vehicle on the road. That’s not something you can determine just by looking at who hit whom. It takes a real investigation, one that goes beyond the crash scene and digs into the details that really matter.
