A motorcycle collision can leave several injuries that affect daily life together: a wrist that limits lifting, a leg that makes standing difficult and scarring that remains after the wounds heal. It is understandable to ask whether each injury attracts its own amount.
For general damages, the assessment is not a shopping list of separate payouts. The legal rules aim to reflect the injury’s adverse impact on the person, including the combined effect where there is more than one injury. Understanding that process makes a valuation explanation easier to assess.
Which part of the claim does the ISV assess?
The Civil Liability Act 2003 defines general damages by reference to pain and suffering, loss of amenities or expectation of life, and disfigurement. Section 61 requires a court assessing general damages within its scope to assign an ISV from zero to 100 under the prescribed rules.
That assessment does not calculate wages already lost, future earning capacity, medical expenses or assistance. Those heads of loss need their own legal and evidentiary assessment. A person may have a substantial supported earnings loss without the ISV being a percentage multiplier for that loss.
The motorcycle claim-amount guide explains the wider valuation. This companion develops the particular multiple-injury rules, rather than estimating the whole settlement from a medical label.
Does this framework apply to every injured rider?
No. The claim’s governing law must be identified before using the scale. Section 5 excludes specified liabilities and damages from the Act, including relevant work injuries, with qualifications. Actual compensation payments are not the only consideration in that provision.
A person injured while riding for work, commuting or performing a delivery needs the work and motor-claim interaction assessed. Do not assume that choosing to submit only a CTP claim makes the Civil Liability Act apply. The WorkCover and CTP guide explains why the routes and payments need coordination.
The accident date and legislative version also matter. The current Civil Liability Regulation 2025 sets out the ISV rules and ranges. Applying current wording to an older event is a legal question to check, rather than an assumption supplied by this guide.
What does the dominant-injury approach mean?
Schedule 2, section 3 of the Regulation directs the court to consider the range for the dominant injury when assessing multiple injuries. It permits a higher assessment within that range than would be appropriate for the dominant injury alone, to reflect the combined adverse impact.
The approach recognises that another injury can matter without requiring every individual value to be added. For example, a restriction affecting one hand may have a greater practical effect when a leg injury also limits mobility and the person cannot compensate in their usual way.
Identifying the dominant injury and the appropriate point in its range requires legal assessment informed by the medical and functional evidence. The most dramatic initial diagnosis, largest scar or highest impairment percentage should not simply be assumed to answer those questions.
| Information | What it can help explain | What it does not decide alone |
|---|---|---|
| Diagnosis and treatment history | The nature, severity and course of each injury | A fixed payout for that diagnosis |
| Medical impairment assessment | Supported permanent functional impairment | The ISV or a percentage of total damages |
| Combined daily-life restrictions | How the injuries interact and affect usual activities | An automatic addition of each injury’s individual value |
| Earlier health and function | The accident-related change or aggravation | Compensation for every pre-existing difficulty |
Can the combined assessment exceed the dominant injury’s range?
Yes, in the circumstances addressed by schedule 2, section 4. If the combined adverse impact is so severe that the maximum dominant ISV is inadequate, the court may assess an ISV above that maximum.
The rule says the combined ISV must not exceed 100 and should rarely be more than 25 per cent higher than the maximum dominant ISV. If the increase exceeds that 25 per cent level, the court must give detailed written reasons.
This is not a standard 25 per cent bonus for having two injuries. Nor is 25 per cent expressed as an absolute ceiling in every case. The inadequacy of the maximum dominant ISV, severity of the combined impact and reasons for the assessment are central. Ask how the particular evidence supports the approach proposed for your claim.
Is whole person impairment the same as the ISV?
No. Schedule 2 expressly makes whole person impairment an important consideration, but not the only one. It also addresses the weight given to specified medical assessments and the information an impairment report must contain.
For example, the report requirements include explaining the clinical findings and calculation, and applicable AMA 5 criteria where used. Under section 11, a report stating a whole person impairment percentage must not identify the schedule 3 injury item or assign an ISV.
The roles are different: medical evidence describes the condition and impairment, while the legal assessment applies the statutory framework to that evidence and the person’s adverse impact. Asking a doctor to certify a desired payout or ISV confuses those tasks.
How are psychological consequences and earlier conditions treated?
Schedule 2 distinguishes an adverse psychological reaction to a physical injury from a mental disorder for which the psychiatric impairment rating provisions are relevant. The former must be treated as a feature of the physical injury. The latter involves requirements for expert assessment and a compliant PIRS report before the rating can be accepted by the court.
This is a legal assessment distinction, not a reason to minimise symptoms or diagnose yourself. Describe changes in sleep, mood, confidence and usual activities accurately to your treating practitioner. A separate diagnosis should not be assumed from ordinary distress, nor should genuine symptoms be hidden because another physical injury is prominent.
For an aggravated pre-existing condition, section 7 allows regard only to the extent it was made worse by the injury. The pre-existing conditions guide explains the before-and-after evidence. A complete history helps distinguish accident-related change from an earlier restriction.
What evidence explains the combined impact?
Describe the activities that changed and how the injuries interact. A statement that “everything hurts” is less informative than explaining that limited grip and difficulty standing together prevent a usual household task, or that assistance is needed where the person previously managed independently.
Keep the account accurate over time. Improvement, remaining difficulty and the methods used to manage a task all matter. Returning to one activity does not necessarily resolve every restriction, but an assessment should not ignore activities that have resumed.
Separate the consequences within general damages from expenses or work losses assessed elsewhere. Missing an enjoyable activity and losing wages while unable to perform a job can both be relevant, but the legal assessment must explain each component and avoid counting the same loss twice.
How does the ISV become a dollar amount?
Section 62 provides for the general-damages calculation using the base amount, if any, and variable amount fixed by the relevant ministerial notice for the period in which the injury arose. The ISV is therefore a step in a statutory calculation, not itself a cash figure.
Check which period the calculation uses before comparing tables or estimates. A table currently displayed online should not automatically be applied to an older accident merely because the claim is being discussed today. This guide deliberately does not reproduce an indexed dollar table or provide a personal calculation.
Even a properly explained general-damages figure is not the final settlement or net recovery. Other losses, any contribution finding, applicable repayments and legal costs remain separate questions in the overall assessment.
Two injuries affecting one task: a hypothetical example
Illustration only: In this hypothetical example, a rider has continuing wrist and leg restrictions after a collision. Each affects daily activities, and their combination makes some tasks harder than either restriction would alone.
The assessment would consider the relevant injury ranges, dominant injury and supported combined impact. It would not simply add two guessed ISVs. The example assigns no diagnosis, score, percentage increase or damages amount.
What should you do next?
- Step 1 Identify the claim route, accident date and whether work-related circumstances affect the governing law.
- Step 2 Keep an accurate record of diagnoses, treatment, earlier conditions and changes over time.
- Step 3 Describe the practical interaction of the injuries, including activities that have improved or resumed.
- Step 4 Obtain appropriate medical evidence without asking a practitioner to select an ISV or payout.
- Step 5 Ask how the dominant-injury range, combined impact and any proposed increase have been assessed.
- Step 6 Separate general damages, other losses and estimated net recovery when reviewing an offer.
Frequently Asked Questions
Do I add the ISVs for all my injuries?
No. The prescribed multiple-injury approach uses the dominant injury’s range and the combined adverse impact, with a separate provision where the maximum dominant ISV is inadequate. Each injury can be relevant without producing a simple arithmetic total of separate injury values.
Does having two injuries guarantee a 25 per cent increase?
No. The 25 per cent wording concerns the particular assessment above the maximum dominant ISV under schedule 2, section 4. It is neither an automatic uplift nor an absolute ceiling in every case. The statutory conditions and reasons for any increase need to be addressed.
Does a 10 per cent impairment mean ISV 10?
They are different assessments. Whole person impairment is important evidence, but the rules require other relevant matters to be considered. A medical percentage should not simply be relabelled as an ISV or applied to the total damages as a settlement percentage.
Can my doctor give me the correct ISV?
The Regulation distinguishes the medical report from the legal ISV assessment. Its requirements for a report stating whole person impairment expressly prohibit identifying a schedule 3 injury item or an ISV. Your doctor can provide the appropriate clinical findings and impairment explanation; the statutory valuation needs separate assessment.
Will psychological symptoms always be added separately?
No automatic separate addition follows. The rules distinguish a psychological reaction to physical injury from a mental disorder assessed under the relevant psychiatric provisions. Report symptoms to an appropriate practitioner and obtain advice about their legal treatment rather than assuming either category applies.
Does the general-damages figure tell me what I receive?
No. It is one component of an injury assessment. Other supported losses, liability or contribution issues, applicable repayments and legal costs affect the overall settlement and net recovery. Ask for each stage of the calculation to be explained separately.
