Add-On Cover (Rider)

An add-on cover (or insurance rider) refers to an optional insurance policy that a policyholder can voluntarily attach to a primary policy (main contract) according to their specific protection needs. It cannot exist independently and strictly requires an active and valid primary policy as its prerequisite. In motor insurance, add-on covers serve as a supplement and extension to the primary policy (such as Comprehensive Own Damage cover), primarily catering to vehicle owners seeking tailored risk protection against specific natural perils, special usage scenarios, or designated property losses.

Core Attributes and Underwriting Rules

The provision and operation of add-on covers adhere strictly to legal insurance principles and market regulatory standards: 

Principle of Dependency and Subordination:

Add-on covers cannot be purchased as standalone products; their coverage period and validity are entirely contingent upon the primary policy. If the main policy contract lapses, is cancelled, or terminated, the corresponding add-on cover will automatically lapse or terminate as well. 

Voluntary Selection and Customised Configuration:

Unlike statutory compulsory coverage (such as mandatory third-party liability insurance), add-on covers are entirely optional. Vehicle owners can flexibly mix and match different endorsements based on their vehicle usage frequency, parking environment, travel routes, and individual risk appetite to construct a more comprehensive protection package.

Common Motor Add-On Covers and Scope of Protection

Under the current comprehensive motor insurance framework, several liabilities that previously required standalone endorsements have been partially integrated into the comprehensive own damage policy, though multiple specialised add-ons for specific risks remain available:

Absolute Excess Add-On: 

Allows policyholders to lower their commercial motor insurance premium by agreeing to a designated absolute excess rate (such as 5% or 10%). In the event of an accident claim, the insurer will assess and disburse compensation only after deducting the agreed absolute excess.

Goods in Transit Liability Add-On: 

Covers the statutory compensation liability borne by the insured when cargo carried on the insured vehicle sustains direct damage or total loss due to a road accident during transit. This is widely utilised for commercial freight and logistics transport vehicles. 

Mental Anguish Indemnity Liability Add-On: 

In the event of a road traffic accident causing third-party bodily injury or death where compensation for emotional distress is legally awarded, the insurer provides indemnification up to the stipulated policy limit.

Public Holiday Double Limit Add-On:

Designed for peak holiday periods characterised by heavier traffic volumes and elevated accident risks, this endorsement automatically doubles or increases the liability limit of specified primary or third-party policies during gazetted public holidays.

Claims and Compliance Governance Requirements 

Claim Preconditions and Liability Determination:

When filing a claim under an add-on cover, the cause of the accident must strictly fall within the defined insured perils specified in the endorsement wording. If the primary policy denies liability, the add-on cover will generally not indemnify the claim either.

Duty of Disclosure and Confirmation of Exclusion Clauses:

When a policyholder opts for an add-on cover, the insurer is obligated to provide clear explanations regarding policy exclusions, liability limits, and compensation calculation methods. If the insured vehicle undergoes a change in vehicle usage (such as converting a private car for commercial hire/e-hailing use) without prompt notification to the insurer, resulting in a material increase in risk, the insurer reserves the right to repudiate liability under the add-on cover.
