I’m so sorry you totaled your car, and I hope everyone is okay! When your car is totaled, your insurance provider will usually send it to an auction or salvage yard, so your first step is to contact your insurer to see if they’ve officially sent it off yet.
If you want to keep the car, some companies will skip the auction process and turn the car over to you immediately. If this is the case, they will still pay you the value of the car, but they may deduct the amount that the car would have sold for at the auction.
