Gap Insurance
Optional coverage for the difference in the amount owed on a vehicle and its replacement value. For example, if your car's replacement value is $4,000, but you still owe $5,000 on it and it's totaled, your insurance company will only pay you $4,000 (unless you have gap insurance). The company that lent you the money for your car will require an immediate payment of $5,000. Gap insurance makes up this difference.
