When a car belonging to an owner is insured with the insurance company and it is being driven by a driver employed by the insured, when it meets with an accident, the primary liability under law for payment of compensation is that of the driver. Once the driver is liable, the owner of the vehicle becomes vicariously liable for payment of compensation. It is this vicarious liability of the owner that is indemnified by the insurance company. A third party for whose benefit the insurance is taken, is therefore entitled to show, when he moves under Section 166 of the Motor Vehicles Act, that the driver was negligent in driving the vehicle resulting in the accident; that the owner was vicariously liable and that the insurance company was bound to indemnify the owner and consequently, satisfy the award made. Therefore, under general principles, one would expect the driver to be impleaded before an adjudication is claimed under Section 166 of the Act as to whether a claimant before the Tribunal is entitled to compensation for an accident that has occurred due to alleged negligence of the driver. Why should not a Tribunal insist on the driver of the vehicle being impleaded when a claim is being filed?
