Case question

Why can an EDR contain evidence of events that a conventional vehicle-history source does not show?

What the evidence showed

In a Corolla matter, the EDR contained multiple stored events while the vehicle-history section reported no accident records. The two sources answer different questions: one reflects data preserved by the vehicle; the other reflects externally reported history.

Practical takeaway

Vehicle history and EDR memory are complementary, not interchangeable. Absence from a history database does not erase a valid vehicle-resident event, and a stored event still requires authentication.

The source evidence exhibit is provided below.
