There are additional coverages you can buy. You can purchase towing coverage, which will pay the costs if your car needs to be transported after an accident. If you're a member of an auto club, you probably don't need this coverage.
You can buy rental reimbursement, which will pay for a rental car you use while your vehicle is being repaired. (If the accident was not your fault, the cost of the rental car should be picked up by the other person's insurance company.)
