Insurer Held Liable Where Insured Tractor Causes Death on Attached Trailer; Recovery from Owner Permitted

A bench of Justices Sudhanshu Dhulia and Ahsanuddin Amanullah heard an appeal by an insurer challenging a Karnataka High Court order that enhanced motor-accident compensation and fastened liability on the insurer where the deceased was travelling on a trailer attached to an insured tractor. The appeal contested whether the insurer of the tractor was liable when the trailer was not separately insured and whether the compensation awarded by the tribunal and upheld by the High Court exceeded policy limits and statutory liability.

The Court dismissed the appeal subject to specified adjustments and directions, upholding the High Court’s enhancement of compensation from Rs.9,50,000 to Rs.13,28,940 with interest at 6% per annum. The Court held that where the tractor — which was insured — was the "root cause" of the accident while pulling the trailer, the liability of the tractor’s insurer extended to the death caused "through the trailer", and technical distinctions requiring separate trailer insurance did not apply to the facts of the case. The Court, in its reasoning, observed: “Thus, the liability of the tractor/its insurer extended to the accident caused by the tractor resulting in the death of the deceased, through the trailer. This being the position in the present case, the principles emanating from the decisions where the Courts have held that the trailer has to be separately registered with the insurance company to make it liable, would not be applicable. To that extent, the facts in the present case are clearly distinguishable from the ones cited by learned counsel for the appellant. The legislation i.e., the MV Act, being beneficial and welfare-oriented in nature [Ningamma v United India Insurance Co. Ltd., (2009) 13 SCC 710; K Ramya v National Insurance Co. Ltd., 2022 SCC OnLine SC 1338, and; Shivaleela v Divisional Manager, United India Insurance Co. Ltd., 2025 SCC OnLine SC 563] and ultimately the root cause of the accident being the tractor, which was insured, this crucial fact cannot be lost sight of. For further clarification, we might illustrate: if an insured vehicle hits another vehicle which in turn hits a third vehicle, then for the entire chain of accidents, the liability would pass on to the vehicle which was the root cause of the accident because it is the result of the action in the same chain of events which cannot be segregated or compartmentalized. Moreover, this Court is duty-bound to be mindful of the ground realities of our nation and cannot let practicality be overshadowed by technicality.” The Court also reiterated that "the Appellant ought not to be saddled with payment of compensation exceeding what the insurance policy provides for or the limit, if any, set under any law for the time being in force," and therefore allowed recovery of any differential from the vehicle owner.

Background The deceased, Nagarajappa, died on 29 February 2012 when a trailer attached to a tractor toppled; the tractor’s driver was found to have driven rashly. The claimants — the wife and two minor daughters — filed a petition before the Motor Accident Claims Tribunal (MACT), which awarded Rs.9,50,000 with 6% interest and held that the risk to an employee on the trailer was not statutorily covered under Section 147(1)(b) of the Motor Vehicles Act, fixing liability on the owner and driver. The claimants appealed to the Karnataka High Court, which enhanced compensation to Rs.13,28,940 and fastened liability on the insurer of the tractor. The Royal Sundaram Alliance Insurance Company challenged the High Court order in this appeal.

The insurer argued that the policy did not specifically cover the trailer or persons carried on it, that the MACT’s decision had been accepted by the owner/driver who had not appealed, and that established precedents limited insurer liability to policy terms and statutory caps (citing C M Jaya and New India Assurance decisions). The Court examined Section 147 of the Motor Vehicles Act, the policy clauses (which limited liability to amounts required by the Act and specified small premium entries for trailers and coolies), and precedents including Dhondubai and the five-judge decision in C M Jaya. The Court distinguished authorities holding that separate trailer registration/insurance was necessary where the trailer itself was the proximate cause, concluding that where an insured tractor was the root cause, insurer liability attached for the resultant chain of events. The Court directed payment of the enhanced award within two months after adjusting amounts already paid and granted the insurer liberty to recover from the owner the differential between the award and the insurer’s maximum contractual or statutory liability. No costs were awarded.
