In the case of cars being swept away due to torrential rains, you will have to file an FIR for loss of vehicle. Typically, the vehicles will be located after a few days. If not, this will be treated as a total loss and insurers will pay out the insured declared value (IDV) of the car. If it is located and the cost of repairs is more than 75 percent of the IDV, again, amount equal to the IDV will be paid out.
