Why the Official Report Matters

The official accident report documents key facts—who was involved, where and when it happened, the officer's fault determination, and witness statements. Insurance companies rely on it to process claims.

Without this report, proving fault becomes significantly harder. Even if you don't plan to file a lawsuit, having the official record protects you if the other party's insurance disputes your account.
