Commentary by Attorney Michael Grossman

I’ve handled hundreds of commercial vehicle accident cases, and head-on collisions are often the most complex ones. Not only does the severe impact create a rather chaotic accident scene, but the serious and fatal injuries that often result make it challenging to get all sides of the story. Authorities aren’t always equipped for such challenging investigations, which is why it’s often more prudent to ensure there are independent investigators looking things over. At worst, they can simply confirm what authorities already know. At best, they can catch mistakes or oversights and help set the record straight.

I recall one case we had a while back where authorities ultimately blamed the driver of a car for losing control and crossing the center line. That person wasn’t around to tell their side of the story, though, so the family wanted a second opinion. Through more rigorous independent investigations, the evidence ultimately showed that authorities got the facts wrong. It was the truck that initially drifted left of center, and the victim swerved trying to avoid the collision. Unfortunately, the truck veered back in the same direction, leading to the collision.

I’m not trying to suggest anything like that happened here, but that example is often a stark reminder that families should trust their gut if they feel they’re not getting the answers they deserve. Families should feel confident they’re getting the whole story. If authorities leave too many unanswered questions, it’s only reasonable that a second set of eyes may be necessary to finally get a proper resolution. It wouldn’t be all that unusual if similar steps were taken here.
