Single-vehicle crashes on interstates often get written off as driver error. But when a car suddenly veers off course and slams into a guardrail, there are plenty of unanswered questions that deserve more than just a passing glance.

1. Did the authorities thoroughly investigate the crash?
Losing control on a highway isn't always straightforward. Investigators need to ask whether the vehicle swerved to avoid something, if speed was a factor, or if any pre-impact maneuvering was attempted. Was the scene mapped in detail? Did anyone examine tire marks or gather data to reconstruct what happened? Without that level of work, important context—like whether the driver was reacting to something—can easily get lost.

2. Has anyone looked into the possibility that a vehicle defect caused the crash?
When a car unexpectedly leaves its lane or spins out, mechanical failures should always be on the table. Tire blowouts, steering issues, or electronic stability system malfunctions can all produce the same results as a mistake behind the wheel. If no one inspected the vehicle’s systems closely after the crash, any such issue could go unnoticed, especially in a case where the driver is unable to describe what happened.

3. Has all the electronic data relating to the crash been collected?
The Accord likely has event data recorders that captured key information—steering angle, brake pressure, speed, and even whether any alerts were active before the crash. Reviewing that data could help confirm whether the driver attempted to avoid something or if the vehicle acted on its own. Investigators should also look into any phone usage or traffic camera footage to round out the timeline.

It's not just about what’s seen at the scene—it’s about what might be hiding underneath. Without a thorough investigation, this crash risks being labeled as “just another accident” when the truth might tell a different story.

Takeaways:

• One-car crashes on interstates should still be deeply investigated.
• Mechanical problems can mimic driver mistakes unless ruled out.
• Vehicle data often provides the only clues when the cause isn't clear.
