Two-Party Accident

A two-party accident (Two-Party Accident / Multi-Party Accident) refers to a road traffic incident involving two or more motor vehicles, non-motorised vehicles, or pedestrians. This includes direct contact such as collisions or side-swipes, as well as non-contact incidents where one party's driving behaviour causes loss or damage to another party, resulting in bodily injuries, fatalities, or property damage. Two-party accidents represent the most common and legally complex scenario in Third-Party motor insurance claims.

Principles of Liability Apportionment in Two-Party Accidents

In a two-party accident, establishing liability is crucial in determining insurance payout ratios and how claims are processed. Under road traffic laws and regulations, liability is generally classified into the following statutory tiers:

Total Liability and Zero Liability: 

Occurs when one party’s traffic violation is the sole cause of the accident, making them 100% liable while the other party bears zero fault. In insurance claims, the non-fault party is typically compensated via the at-fault driver's compulsory traffic insurance and commercial Third-Party policy. 

Primary Liability and Secondary Liability: 

Applicable when both parties commit traffic violations that contribute unequally to the incident. The party primarily responsible bears major liability (typically around 70%), while the other party bears minor liability (typically around 30%). 

Equal Liability:

Occurs when both parties' traffic violations contribute equally to the accident, with each bearing 50-50 liability. Insurers will apportion and cover 50% of the opposing party's losses within their respective liability policy limits. 

Key Features of the Claims Process in Two-Party Accidents

Unlike single-vehicle accidents, claims for two-party accidents involve traffic police findings, liability apportionment, and cross-compensation procedures: 

Mandatory Police Reporting and Scene Preservation:

When an accident occurs, both drivers are required to preserve the scene and lodge a police report immediately. Except for minor collisions eligible for expedited settlement, traffic authorities must inspect the scene and issue an official Road Traffic Accident Liability Determination Certificate, serving as the legal foundation for civil liability and compensation.

Cross-Settlement Between Compulsory and Commercial Third-Party Insurance:

Payouts adhere to the "compulsory coverage first, commercial coverage second" rule. Claims are settled first under the compulsory traffic insurance limits without apportioning liability percentages. Any remaining losses exceeding compulsory policy limits are then calculated and borne by the commercial Third-Party Liability insurance based on the liability proportions specified in the official accident report.

Application of the Right of Subrogation:

If the at-fault party unreasonably refuses or fails to compensate the victim, the non-fault (or partially liable) policyholder can claim under their Own Damage (Comprehensive) cover first. The insurer will settle the claim and subsequently exercise its legal right of subrogation to recover the losses from the third-party driver.

Impact of Two-Party Accidents on Premiums and NCD

The determination of fault in a two-party collision directly affects future motor insurance renewal premiums: 

At-Fault Claims and Premium Revisions: 

If the insured vehicle is held liable (whether primary, equal, or secondary fault) and a claim payout is made under the commercial policy, the vehicle’s No Claim Discount (NCD) will be adjusted downwards, resulting in higher renewal premiums for the following year or the forfeiture of cumulative discount privileges.

Protection of NCD for Non-Fault Parties:

If traffic authorities confirm that the policyholder carries zero liability in the collision and no payout is incurred under their own commercial policy, the accident will not affect their NCD. This safeguards the discount entitlements and premium rates of non-fault drivers upon renewal.
