Gap insurance protects you by paying the shortfall amount owed to the credit provider in the event that you have a total loss due to accident, theft or damage and the amount received from the comprehensive insurer is inadequate to finalise the loan on the vehicle. When you borrow money to purchase a vehicle you may be exposed to this insurance shortfall or gap. This gap is the difference between the insured value of the vehicle and the remaining balance required to finalise the loan or lease.
