When a claim is filed against your car insurance, it's routine for your insurance company to contact you quickly. This immediate communication is part of the standard procedure to keep you informed.
Your insurance company is unlikely to move forward with a claim without informing you. They operate as a for-profit entity and their bottom line matters. This means they won't hastily payout a claim. Even if there's a police report, your insurance provider will typically involve an adjuster and conduct a thorough investigation before making any decisions.
