An Exposition of Section 166 of the Motor Vehicles Act, 1988: Principles, Procedures, and Judicial Interpretations in India

Introduction

Section 166 of the Motor Vehicles Act, 1988 (hereinafter "M.V. Act") stands as a cornerstone of motor accident compensation jurisprudence in India. It provides a statutory framework for claiming compensation for death or bodily injury arising out of the use of a motor vehicle, predicated on the principle of fault liability. This provision empowers victims or their legal representatives to approach the Motor Accidents Claims Tribunal (MACT) to seek "just compensation." Over the decades, the interpretation and application of Section 166 have been significantly shaped by judicial pronouncements, particularly from the Supreme Court of India, which have aimed to ensure fairness, adequacy, and a degree of uniformity in compensation awards. This article undertakes a comprehensive analysis of Section 166, delving into its foundational principles, procedural intricacies, the judicial methodology for determining compensation, aspects of liability, its interplay with other legal provisions, and the impact of recent legislative amendments.

I. The Foundation of Section 166: Fault Liability and 'Just Compensation'

A. The Principle of Fault Liability

Unlike Section 163-A of the M.V. Act, which provides for compensation on a structured formula basis without the need to prove fault (no-fault liability), a claim under Section 166 is rooted in tortious principles, primarily requiring the claimant to establish negligence on the part of the driver or owner of the offending vehicle. The Supreme Court, in cases like Deepal Girishbhai Soni And Others v. United India Insurance Co. Ltd., Baroda (2004 SCC CRI 1623), has emphasized this distinction, clarifying that Section 163-A is a separate code and an award thereunder is final, precluding a subsequent claim under Section 166. This was reiterated in Ningamma And Another v. United India Insurance Company Limited (2009 SCC 13 710), where it was held that if a claim cannot be sustained under Section 163-A (e.g., the deceased driver not being a third party), the claimants may pursue a remedy under Section 166, provided they can prove negligence. The Jharkhand High Court in ADITYA BIRLA CHEMICALS INDIA LIMITED v. X (2025) explicitly stated that accepting an argument that negligence is not required to be proved under Section 166 would obliterate the distinction between Section 163-A and Section 166.

B. The Overarching Goal: 'Just Compensation'

Section 168 of the M.V. Act mandates that the MACT shall make an award determining the amount of compensation which appears to it to be "just." The concept of "just compensation" is the bedrock of Section 166. The Supreme Court in Rajesh And Others v. Rajbir Singh And Others (2013 SCC 9 54) and Sarla Verma (Smt) And Others v. Delhi Transport Corporation And Another (2009 SCC 6 121) elaborated that "just compensation" means what is fair, equitable, and reasonable, and should be commensurate with the loss suffered. It is not intended to be a windfall nor a pittance. The judiciary has continuously strived to interpret this term dynamically to reflect socio-economic realities and ensure victims are adequately restituted.

C. Locus Standi: Who Can Apply?

Section 166(1) of the M.V. Act specifies who can make an application for compensation. An application can be made by: (a) the person who has sustained the injury; or (b) the owner of the property (where damage to property is caused); or (c) where death has resulted from the accident, by all or any of the legal representatives of the deceased; or (d) by any agent duly authorised by the person injured or all or any of the legal representatives of the deceased, as the case may be. The provision ensures that those directly affected by the accident have the right to seek redressal.

II. Procedural Framework for Claim Adjudication

A. Initiation of Claim Proceedings

A claim under Section 166 is initiated by filing an application before the MACT having jurisdiction over the area where the accident occurred, or where the claimant resides or carries on business, or where the defendant resides. The application must contain prescribed particulars, including details of the accident, vehicles involved, injuries sustained or death, and the amount of compensation claimed.

B. The Role of Accident Information Report (AIR) and Section 166(4)

Section 158(6) of the M.V. Act (now Section 159 post-2019 amendment) mandates the police to forward a copy of the accident information report (AIR) to the concerned MACT and the insurer within a specified period. Section 166(4) further provides that the MACT shall treat any report of accidents forwarded to it under Section 158(6) as an application for compensation under Section 166. The Supreme Court in Jai Prakash v. National Insurance Company Limited And Others (2009) directed Claims Tribunals to register such reports as applications for compensation and deal with them without waiting for formal claim applications. This proactive approach was also emphasized in General Insurance Council And Others v. State Of Andhra Pradesh And Others (2010 SCC 6 768), aiming to expedite relief to victims.

C. The Imposition of Limitation: Section 166(3) and its Implications

Prior to the Motor Vehicles (Amendment) Act, 2019, there was no period of limitation prescribed for filing a claim petition under Section 166. However, the 2019 Amendment introduced sub-section (3) to Section 166, which stipulates: "No application for compensation shall be entertained unless it is made within six months of the occurrence of the accident." This has been a significant procedural change. The applicability of this amendment to accidents occurring before its enforcement has been a subject of judicial scrutiny. For instance, the Sikkim High Court in AITA MAYA GURUNG AND ORS. v. RATNA KUMAR PRADHAN AND ORS. (2023 SCC ONLINE SIKK 31) considered a case where the accident occurred in 2010 and the claim was filed in 2019, after the amendment. The court noted the notification appointing the date for the amendment to come into force. Recent judgments from the Himachal Pradesh High Court, such as SBI GENERAL INSURANCE COMPANY LTD v. SHER ALI AND ANOTHER (2025), SBI GENERAL INSURANCE COMPANY LTD v. DHUMAN AND ANOTHER (2025), and others, have also grappled with claims filed after six months, emphasizing that the MACT is a creature of statute and must adhere to its provisions.

III. Judicial Determination of 'Just Compensation' under Section 166

A. Standardisation of Assessment: The Path Forged by the Apex Court

The determination of "just compensation" under Section 166, while inherently fact-dependent, has been significantly streamlined and standardized through landmark pronouncements of the Supreme Court. The objective has been to bring uniformity, consistency, and predictability to compensation awards, minimizing subjectivity.

B. Calculation of Pecuniary Damages

Pecuniary damages are awarded for actual monetary losses suffered by the claimants.

1. Loss of Dependency and the Multiplier Method

In death cases, the primary component of compensation is "loss of dependency." This is calculated by determining the multiplicand (annual contribution of the deceased to the family) and multiplying it by an appropriate multiplier. The Supreme Court in Sarla Verma (Smt) And Others v. Delhi Transport Corporation And Another (2009 SCC 6 121) laid down a standardized multiplier table based on the age of the deceased (or the claimant, whichever is higher, in certain contexts, though *Sarla Verma* primarily focused on the deceased's age). This was further affirmed and refined in National Insurance Company Limited v. Pranay Sethi And Ors. (2017 SCC ONLINE SC 1270), which endorsed the *Sarla Verma* multiplier table.

2. Ascertainment of Income and Future Prospects

The multiplicand is determined based on the deceased's established income at the time of death. A crucial element in this calculation is the addition for "future prospects." In Sarla Verma, the Court suggested additions for future prospects for those with permanent jobs. This was expanded in Rajesh And Others v. Rajbir Singh And Others (2013 SCC 9 54) to include self-employed and fixed-salary earners. The Constitution Bench in Pranay Sethi (2017) provided definitive percentages for addition towards future prospects based on the age and nature of employment of the deceased (e.g., 40% for permanent job if deceased below 40 years; 25% for self-employed between 40-50 years). The Chhattisgarh High Court in Savitry Dahriya And Others v. Shailendra Kumar Vaishnav And Others (2020) clarified that these principles of future prospects apply to Section 166 claims, not Section 163-A claims which follow a structured formula.

3. Deductions for Personal Expenses

From the deceased's income, a deduction is made for personal and living expenses that the deceased would have incurred. Sarla Verma (2009) standardized these deductions: 1/2 for a bachelor, 1/3 if the deceased was married with 2 to 3 dependent family members, 1/4 with 4 to 6 dependents, and 1/5 if more than 6 dependents. *Pranay Sethi* (2017) largely upheld these deductions.

C. Non-Pecuniary Damages (Conventional Heads)

In addition to pecuniary damages, claimants are entitled to non-pecuniary damages under conventional heads. Pranay Sethi (2017) standardized these amounts: Rs. 15,000 for loss of estate, Rs. 40,000 for loss of consortium (spousal, parental, and filial), and Rs. 15,000 for funeral expenses. It also provided for a 10% increase in these amounts every three years. These were built upon earlier guidelines in cases like Rajesh (2013).

IV. Establishing Liability in Section 166 Claims

A. The Indispensability of Proving Negligence

As stated earlier, proof of negligence on the part of the driver of the motor vehicle is a sine qua non for a successful claim under Section 166. The burden of proving negligence rests on the claimant, based on the preponderance of probabilities. In Oriental Insurance Co. Ltd. v. Meena Variyal And Others (2007 SCC 5 428), the Supreme Court emphasized the necessity of proving negligence for establishing liability under the M.V. Act. The principle was reiterated by the Jharkhand High Court in ADITYA BIRLA CHEMICALS INDIA LIMITED v. X (2025).

B. Composite Negligence: Joint and Several Liability

In cases of "composite negligence," where the accident is caused by the wrongful act or neglect of two or more persons (joint tortfeasors), the liability of these tortfeasors is joint and several. The Supreme Court in Khenyei v. New India Assurance Company Limited And Others (2015 SCC 9 273) clarified that the claimant can sue any one or all of the joint tortfeasors and recover the entire compensation from any of them. The apportionment of liability between the tortfeasors is for them to settle inter se and does not affect the claimant's right to recover the full amount from any chosen tortfeasor.

C. Liability of the Insurer and Available Defences

The insurer's liability is statutory, arising from the insurance policy issued under Chapter XI of the M.V. Act. The insurer steps into the shoes of the insured (owner of the vehicle) to indemnify the third-party victim. However, the insurer can avail of statutory defences available under Section 149(2) of the M.V. Act, such as breach of policy conditions (e.g., driver not holding a valid driving licence, use of vehicle for an unauthorized purpose). In Oriental Insurance Co. Ltd. v. Meena Variyal And Others (2007), the Supreme Court held that an insurance policy does not automatically cover employees of the insured unless specifically stated or liability arises under the Workmen's Compensation Act, 1923, thus limiting the insurer's liability in such specific contexts even in a Section 166 claim.

D. Relevance of Driver's Conduct Post-Accident

Section 134 of the M.V. Act imposes a duty on the driver of a vehicle involved in an accident causing injury or damage to take reasonable steps to secure medical attention for the injured and report the accident to the police and insurer. Failure to comply with these duties is punishable under Section 187 of the M.V. Act, as discussed in Basappa v. State Of Karnataka (2014) and State Of Arunachal Pradesh v. Ramchandra Rabidas Alias Ratan Rabidas And Another (2019). While these are penal provisions, a driver's conduct post-accident, such as fleeing the scene or failing to provide aid, can sometimes be considered by the MACT as circumstantial evidence reflecting on the issue of negligence in a Section 166 claim.

V. Section 166 in Conjunction with Other Legal Provisions

A. The Distinct Regimes of Section 166 and Section 163-A

The M.V. Act provides two distinct channels for claiming compensation: Section 166 (fault-based) and Section 163-A (no-fault, structured formula). As established in Deepal Girishbhai Soni (2004), these are independent provisions, and a claimant cannot pursue both simultaneously or sequentially for the same cause of action. An award under Section 163-A is final. The choice depends on factors like the ability to prove negligence and the income of the deceased/injured (Section 163-A has an income cap for its applicability, as noted in Savitry Dahriya (2020) referencing Deepal Girishbhai Soni). In New India Assurance Co. Limited v. Rukhminibai W/O Ashok Gore Others (Bombay High Court, 2007), where the deceased driver himself was allegedly responsible, the court indicated that a Section 163-A claim might be untenable, implying Section 166 (if negligence of another could be shown) would be the path, though more arduous.

B. Section 140: Interim Relief and its Bearing on Final Adjudication

Section 140 of the M.V. Act provides for interim compensation on a no-fault basis in case of death or permanent disablement. This amount is deductible from the final compensation awarded under Section 166. The Gujarat High Court in Oriental Insurance Company Limited v. Legal Heirs (2013 SCC ONLINE GUJ 2055) clarified that an order passed under Section 140 will not operate as constructive res judicata and will not influence the MACT's decision while adjudicating the main claim petition under Section 166 on merits.

C. Interaction with Employee Welfare Legislations

Questions sometimes arise regarding the maintainability of a Section 166 claim if the injured person is also covered under employee welfare statutes like the Employees' State Insurance Act, 1948 (ESI Act). The Kerala High Court in K.P Kuriakose v. G. Santhosh Kumar & Others (2009 SCC ONLINE KER 6396) held that Section 53 of the ESI Act, which bars receiving compensation under any other law for an employment injury, does not bar a claim in tort under Section 166 of the M.V. Act against a stranger/tortfeasor who is not the employer. The bar operates primarily against claiming from the employer under multiple statutes for the same employment injury.

D. Survival of Cause of Action for Personal Injury Claims

The principle actio personalis moritur cum persona (a personal right of action dies with the person) has exceptions. Section 306 of the Indian Succession Act, 1925, generally excludes causes of action for personal injuries not causing death from surviving the deceased. However, regarding motor accident claims, the legal position has evolved. The Karnataka High Court in Uttam Kumar (Deceased) v. Madhav And Another (2002 SCC ONLINE KAR 219), while referring the matter to a larger bench, noted the need to reconsider earlier views in light of amended M.V. Act provisions. Section 166(1) itself allows legal representatives to claim compensation where death has resulted from the accident. For injuries not resulting in death, if the claimant dies during the pendency of the proceedings due to reasons unrelated to the accident, the claim for pecuniary losses (like medical expenses already incurred, loss of earnings up to death) may survive to the legal representatives, though claims for purely personal losses (like pain and suffering) might not. The Motor Vehicles (Amendment) Act, 2019, inserted Section 166(5), which states: "Notwithstanding anything in this Act or any other law for the time being in force, the right of a person to claim compensation for injury in an accident shall, upon the death of the person injured, survive to his legal representatives, irrespective of whether the cause of death is relatable to or had any nexus with the injury or not." This is a significant clarification impacting the survival of claims.

VI. Conclusion

Section 166 of the Motor Vehicles Act, 1988, remains a vital provision for victims of road accidents seeking redressal based on fault. The judiciary, through a catena of decisions, has meticulously sculpted the contours of "just compensation," striving for a balance between adequacy for the victim and fairness to the defendant/insurer. Landmark cases like Sarla Verma, Rajesh, and Pranay Sethi have infused a significant degree of objectivity and standardization into the assessment process. The recent introduction of a limitation period under Section 166(3) and the clarification on the survival of claims under Section 166(5) by the 2019 Amendment reflect the ongoing evolution of this law. While the fault-based regime of Section 166 presents its own challenges, particularly in proving negligence, it continues to be the primary avenue for comprehensive compensation that aims to restore the claimants, as far as money can, to the position they were in before the accident. The diligent application of established principles by the MACTs, guided by the Supreme Court, is crucial for the effective realization of the socio-welfare objectives underpinning this legislation.
