If you cause a multiple-car accident resulting in several injuries that racks up 1 million dollars in hospital bills. The problem? Your auto insurance policy will cover a maximum of $300,000 per incident. You are found legally obligated to cover the remaining $700,000. Don’t have an extra $700K lying around? That’s where umbrella insurance can help. Umbrella insurance may cover the cost of personal liabilities beyond your current auto, home and/or condo insurance policies.
