Right now, additional details can't be confirmed. However, the most up to date images of this intersection I can find clearly show a stop sign for vehicles on Hemlock. So was this all due to a truck driver failing to yield? If so, it would likely warrant consequences, but investigations would need to consider not just the driver's actions but also the actions of their employer. Otherwise, someone who had a role in this young man's death might slip through the cracks.
Let me give an example of what I mean by this. I had a case a while back involving a trucking company known for its strict delivery schedules. They penalized drivers for late deliveries, even when delays were beyond the drivers' control. Drivers who failed to meet these ridiculous timelines often found themselves at the bottom of the list for future assignments, which could significantly affect their earnings. This policy put immense pressure on drivers to prioritize speed over safety.
Inevitably, this led to disaster. A driver was nearing the end of his route with a delivery deadline looming. Fearful of the repercussions of a late delivery, he chose to skip a scheduled break. Fatigued and under pressure, he lost control of his vehicle, leading to a catastrophic collision. The investigation revealed that the driver had been on the road for an extended period without adequate rest. That was the driver's mistake, without a doubt, but it was also a direct consequence of his employer's negligent policy.
Simply put, when people are quick to put all of their focus on drivers, they can miss serious issues like that. A driver who makes a mistake obviously should face whatever consequences are appropriate. But if that mistake happened due to a dangerous work environment, it's only a matter of time before that company finds another driver to pressure until they, too, get people hurt or killed. Dragging those companies out into the light allows for them to also be held accountable.
So when I read about a crash like this, I'm thinking the same thing everyone else is: What actually went wrong? Also important, though, is the question that comes after that: Who's responsible for it?
