A commercial vehicle is usually insured up to its IDV. This is the vehicle’s ex-showroom price, minus depreciation. In case the vehicle is stolen or damaged beyond, the insurance company will provide the IDV of the vehicle to the insured. Do note that depreciation can reduce the IDV of the vehicle considerably. For instance, after just 4 years, the value of your vehicle would have reduced by 50% due to depreciation.
Therefore, if you wish to remove depreciation from the equation, you can opt for the return to invoice add-on. This will ensure your vehicle is insured up to its current listing price in case of theft or damage that results in total loss of the vehicle.
