Commentary by Attorney Michael Grossman
As open-and-shut as these initial reports may seem, people often find there are obstacles to overcome that require a lot more than a basic summary of the crash. That's why it's often important to ensure investigations are thorough even if the details seem straight-forward.
1. Did the authorities thoroughly investigate the crash?
When one vehicle crosses the line, it’s easy to assume fault and move on. But that shortcut leaves a lot unchecked. Did officers map the scene, review what each driver was doing beforehand, or consider less obvious factors? Often, they’re working with limited time and resources, and deeper investigation gets pushed aside.
2. Has anyone looked into the possibility that a vehicle defect caused the crash?
A sudden lane departure could point to more than just distraction. Steering or brake failure, faulty sensors—any of these could explain the drift. Additionally, serious injuries can sometimes be the result not of a crash but of faulty airbags or seatbelts. Unless someone inspects the vehicle closely, that possibility stays off the radar.
3. Has all the electronic data relating to the crash been collected?
Both vehicles likely have black box data showing speed, braking, and steering before the crash. Phone and GPS records can also help confirm key facts. If that data wasn’t pulled, the investigation may be missing some of the clearest evidence available.
Even when a crash looks simple, skipping steps means missing the truth. A thorough look makes all the difference.
Key Takeaways:
- Even clear-cut crashes need detailed investigation to avoid missed facts.
- Mechanical issues can explain sudden lane departures and often go unchecked.
- Onboard and phone data offer hard proof—if someone takes the time to review it.
