Commentary by Attorney Michael Grossman

When a vehicle crashes without warning, hits fixed objects, and overturns—especially without any other vehicles involved—it often points to a deeper mechanical or situational failure. The aftermath is visible, but the cause isn’t always so obvious.

1. Did the authorities thoroughly investigate the crash?
A crash involving a vehicle striking a concrete wall, flipping, and hitting a pole calls for a detailed reconstruction. Investigators should have looked at the Civic’s movement across lanes, signs of attempted correction, and whether there was any mechanical hesitation before the crash. Without that, it’s unclear whether the driver lost control—or if the vehicle did.

2. Has anyone looked into the possibility that a vehicle defect caused the crash?
A single-vehicle crash like this can often be traced to unexpected mechanical failure. A tire issue, suspension problem, or even a malfunction in steering or stability control could all lead to a sudden veer or rollover. For a car like the Honda Civic, these systems are critical at highway speeds. If no mechanical inspection was performed, the true cause may still be unknown.

3. Has all the electronic data relating to the crash been collected?
Modern vehicles typically log critical information in the seconds leading up to a crash—speed, throttle, braking, and steering activity. That data helps determine whether the driver tried to react, and whether the vehicle responded properly. If those logs haven’t been accessed, it’s difficult to know whether this was a case of driver misjudgment or something the driver couldn’t control.

When a crash this severe happens without a second vehicle involved, it’s not enough to chalk it up to error. The responsibility lies in finding out what actually failed—driver, machine, or both.

Takeaways:

  • Solo crashes involving fixed objects and rollovers demand full scene analysis and path reconstruction.
  • Vehicle systems like steering, tires, and stability control must be inspected for failures.
  • Pre-crash data provides key insight into driver inputs and vehicle behavior just before impact.
