When serious accidents occur, it’s easy to assume the cause is obvious based on initial reports. However, after over 30 years of representing crash victims and their families, I know that understanding what really happened often depends on asking three critical questions—questions that should guide every investigation.

First, did authorities conduct a thorough investigation into the crash? It’s not uncommon for single-vehicle accidents to be quickly attributed to driver error without examining all the facts. A detailed investigation should include documenting the scene, inspecting the vehicle, interviewing witnesses, and considering environmental conditions. Without that diligence, important clues about why a vehicle rolled over or why safety systems might not have worked could go unnoticed.

Second, has anyone looked into whether a vehicle defect contributed to the crash? Reports in this case mention that the Nissan’s airbags did not deploy. That’s a serious red flag that demands a closer look. Airbags are supposed to protect occupants during rollovers and collisions. If they failed to deploy as intended, there may be a deeper issue with the vehicle’s safety systems that needs to be thoroughly investigated by qualified experts.

Third, has all available electronic data been secured? Modern vehicles store critical information about speed, braking, steering, and safety system performance in the moments leading up to and during a crash. Accessing this data could reveal whether the airbags malfunctioned or if other factors played a role. If investigators don’t act quickly to preserve this data, key evidence could be permanently lost.

Asking these questions isn’t about complicating the investigation—it’s about ensuring the full truth comes to light. It’s the least that can be done to make sure those affected by this crash receive the clarity and closure they deserve.
