Liability Of Insurer In Case Of Death On An Attached Trailer: A Legal Analysis

Posted On - 10 June, 2025 • By - Smita Paliwal

Introduction:

The case of The Royal Sundaram Alliance Insurance Company Limited v Smt. Honnamma & Ors[1] addresses a legal dispute arising from a motor vehicle accident involving a tractor and an attached trailer. The core issue is whether an insurance company can be held liable under the Motor Vehicles Act, 1988, when a person traveling on a trailer meets with an accident due to the negligent operation of the insured tractor. The matter concerns interpretation of Section 147 of the Motor Vehicles Act and the extent of coverage under an insurance policy.

Brief Facts:

On 29 February 2012, a person named Nagarajappa was working as a laborer and was traveling in a tractor and trailer for the purpose of unloading soil. During this process, the vehicle overturned. As a result, Nagarajappa sustained injuries that led to his death. The deceased’s wife and two minor daughters (Respondents No.1 to 3) filed a claim petition under Section 166 of the Motor Vehicles Act before the Motor Accident Claims Tribunal (MACT), being M.V.C. No.121/2012, seeking compensation of ₹10,00,000.

Arguments:

Appellant insurance company vehemently submitted that High Court grossly erred in reversing well-reasoned order passed by Motor Accidents Claims Tribunal. Coverage wasn’t extended by insurance policy to passengers riding in trailer apparently. Appellant claimed policy didn’t cover trailer employees of owner or unauthorized passengers because additional coverage options for such risks weren’t bought. Appellant contended High Court erred gravely in overlooking MACT findings and failed utterly in appreciating that both vehicle owner and driver had tacitly accepted MACT’s findings without launching any challenge. Compensation granted by High Court vastly exceeded amount originally claimed in petition starkly contravening fundamental judicial principles inherently. Respondent claimants failed to appear before Court despite being duly served notice. Insurance company alone pursued appeal after driver Respondent No 5 was removed by earlier order dated 20 February 2024.

Analysis:

In the present case, the claimants supported their case by examining the wife of the deceased as PW1 and produced ten documentary exhibits. The appellant, being the insurer of the tractor, examined two witnesses and marked seven documents, which included the insurance policy schedule, registration certificates, charge sheet, and other relevant documents. The MACT awarded compensation of ₹9,50,000 with 6% interest per annum from the date of filing of the petition until realization. However, the Tribunal held that the insurance company could not be held liable since the deceased was traveling on a trailer, which was not covered under the policy. The liability was placed on the owner (Respondent No.4) and the driver (Respondent No.5).

Dissatisfied with the amount awarded, the claimants filed an appeal before the High Court (MFA No.3659/2014) seeking enhancement of compensation. The High Court partly allowed the appeal and enhanced the award to ₹13,28,940 with 6% interest and shifted the liability to the insurance company. Aggrieved by this change in liability, the insurance company filed the present appeal.

The matter revolves around the legal question of whether an insurance company, which has issued a policy for a tractor, can be held liable for an accident that occurred while the tractor was pulling a trailer and a person traveling on that trailer suffered fatal injuries. The MACT had initially ruled that since the trailer was not separately insured, and because the deceased was traveling on the trailer as a labourer, the insurer could not be held liable under Section 147(1)(b) of the Motor Vehicles Act. This provision mandates compulsory insurance for motor vehicles, but the MACT interpreted that it does not extend to trailers unless explicitly covered.

However, the High Court interpreted the statutory provisions differently. The Court emphasized the causal link between the insured tractor’s movement and the accident. Since the trailer was attached to the tractor and moved by its operation, the accident was held to have arisen out of the use of the insured motor vehicle. The Court noted that the trailer had no independent mechanism for movement and could not have caused the accident without the tractor’s operation. Therefore, the trailer and tractor were treated as a single operational unit.

The Court rejected the insurance company’s argument that a trailer requires separate insurance, stating that a trailer is not a “motor vehicle” as defined under the Act since it is not self-propelled. The requirement of insurance under Section 147 pertains to “motor vehicles,” and thus, negligence cannot arise from the independent operation of a trailer. The Court further observed that the purpose of Section 147 is to ensure coverage for death or injury arising from the use of a motor vehicle in a public place. Since the trailer was being used in conjunction with the insured tractor, and the accident arose from that use, the insurance company was held liable.

The Court’s analysis included reference to precedent from other High Courts. It cited United India Insurance Co. Ltd. v. Koduru Bhagyamma[2], a case from the Andhra Pradesh High Court, where it was held that a trailer being towed by an insured tractor does not require separate insurance. Similarly, in Gunti Devaiah v. Vaka Peddi Reddy[3], it was held that a trailer, not being a self-propelled vehicle, does not fall within the scope of independent motor vehicles and does not require individual insurance. The High Court held that the trailer had an independent role in causing the accident, whereas in the present matter, the trailer’s movement was solely dependent on the insured tractor.

Judgment:

Court ruled that insurer of tractor can be held liable under Section 147 of Motor Vehicles Act when trailer attached during accident arising out of tractor operation. A non-motorized trailer forms part of same operational unit and liability arises without separate insurance being necessarily required. Court confirmed High Court’s award of ₹13,28,940 with 6% annual interest and shifted liability squarely onto insurance company thereafter. Denying compensation on basis of technical separation between tractor and trailer contravenes statute’s objective rather starkly it seems. Acknowledging decisions cited by appellant Court found those cases turned on facts starkly dissimilar from present highly contentious matter.

Conclusion:

The judgment emphasizes that insurance liability should be based on how a vehicle is actually used, not just technical classifications. When a trailer is hitched to an insured tractor and both operate as a single unit, the insurer of the tractor is liable for any accident involving that combination—even if the trailer isn’t separately insured. This approach aligns with the purpose of the Motor Vehicles Act, 1988, which aims to ensure compensation for victims of road accidents. The court made it clear that Section 147 covers the entire vehicle setup, and what matters most is the real cause of the accident.
