Motor Vehicle (Third Party Insurance) Act 1943

The Act’s reach is broad. Owners of motor vehicles (defined in s 3(1) to include hirers under hire-purchase or hiring agreements, part-owners, and, in limited circumstances, persons in possession under a bill of sale) must ensure a policy is in force. Drivers (anyone in charge of the vehicle) are covered whether or not they have the owner’s consent. Employers are protected when an employee uses a vehicle in the employer’s business with acquiescence (s 22(1)), but not if the use is without knowledge or contrary to instructions (s 22(2)). The Crown in right of the State or Commonwealth is generally exempt from the obligation to insure but is placed in the same position as an insurer for uninsured State vehicles (s 3(3)–(3A)).

Injured persons (or their dependants) who suffer death or bodily injury directly caused by, or by the driving of, a motor vehicle are the primary beneficiaries. They may claim against the insured driver/owner or, in the case of uninsured or unidentified vehicles, directly against the Commission (ss 7–8). However, their recoverable damages are heavily regulated by the thresholds and caps in ss 3C–3F and 3EA–3FB.

The Commission itself is both insurer and regulator. It assesses premiums annually on an actuarial basis (s 3T), issues policies, investigates and settles claims, and exercises recovery rights against insured persons, owners, drivers and unauthorised users. The Director General (CEO under the Road Traffic (Administration) Act 2008) performs licensing and policy-issuance functions on the Commission’s behalf and may delegate or contract out those functions (ss 3Q–3QB).

Legal practitioners are constrained in the costs they may charge for motor-accident claims (s 27A) and are prohibited from soliciting instructions on a contingency basis (s 27). Visiting motorists from prescribed interstate jurisdictions may rely on their home-state insurance instead of obtaining Western Australian cover (s 3(4)). Manufacturers and dealers holding general identification plates are deemed owners for insurance purposes (s 3(5)).

Finally, the Act affects courts (Supreme, District and Magistrates) by limiting their power to award damages contrary to the statutory caps (s 3B) and by declaring the caps to be substantive law (s 3FA). Interstate courts applying Western Australian law must apply the same restrictions.

Owners and drivers must:

• Ensure a complying policy is in force whenever the vehicle is on a road (s 4(1)).
• Give immediate written notice to the Commission of any accident causing death or bodily injury, with full particulars (s 10(1)–(2)).
• Notify the Commission of any claim and supply particulars (s 10(3)).
• Refrain from admitting liability, settling, or incurring litigation expense without the Commission’s written consent (s 10(5)).
• Submit to medical examination by a health professional nominated by the Commission (s 30).

Injured persons have the right to recover from the Commission where a judgment against an insured person remains unsatisfied (s 7(1)), or directly against the Commission where the driver is dead, unidentifiable or uninsured (ss 7(2)–(3), 8). They must, however, give notice of claim “as soon as practicable” (s 29(1)) and may be required to undergo medical examination (s 30). Rights to damages are subject to the thresholds in ss 3C–3F and the CISS rules in s 3EA.

The Commission enjoys extensive rights:

• To conduct, control and settle claims on behalf of insured persons (s 11).
• To recover from insured persons, owners or unauthorised drivers any sums paid where policy breaches have occurred (ss 7(5), 15).
• To recover from the owner or driver of an uninsured vehicle any amount paid to a judgment creditor (s 8(3)).
• To defend claims on the basis of the statutory caps even if an interstate court has awarded a non-conforming sum (s 3FA(4)–(5)).

Employers have a right to the benefit of the policy when an employee’s vehicle is used in the employer’s business with acquiescence (s 22(1)). The Commission has a right of recovery against unauthorised drivers who cause injury (s 15).

Courts are prohibited from awarding damages contrary to the restrictive provisions (ss 3B, 3EA(6), 3F(3), 3FB(4)) and must treat those provisions as substantive law (s 3FA(2)).

Driving or causing or permitting the driving of an uninsured vehicle carries a penalty of $400 for a first offence and $800 thereafter (s 4(3A)). Conviction ordinarily triggers a 12-month disqualification from holding a driver’s licence or vehicle licence (s 4(4)). Failure to produce evidence of insurance attracts a $200 penalty (s 4(7C)).

Breach of the notice and cooperation obligations in s 10 carries a $20 penalty (s 10(4)), although the Commission may also recover any moneys it has paid or costs incurred (s 10(6)). General offences under the Act attract a maximum penalty of $400 where none is otherwise prescribed (s 28(2)).

False or misleading information given in connection with the Act attracts a fine of $10,000 (s 27B). Obstructing a Commission officer attracts the same penalty (s 27C). Soliciting instructions in breach of s 27 renders any agreement to pay for those services void and the money recoverable (s 27(3)). Costs agreements exceeding the permitted scale under the Legal Profession Uniform Law Application Act 2022 are likewise void (s 27A).

The Commission may apply to the Magistrates Court for disqualification of a person likely to endanger the public (s 18). Licence suspension or cancellation powers exist independently under road traffic legislation.

Enforcement of civil liabilities occurs primarily through actions against the Commission (ss 7–8). Judgments may be enforced as debts. The Commission’s recovery actions against owners, drivers or insured persons may be brought separately or by third-party procedure (ss 7(5), 8(3)).

The Act is expressly supplementary to the Road Traffic (Vehicles) Act 2012 (s 2). Vehicle licensing and the incorporation of the insurance policy into the licence document are integrated (s 4(8)–(8B)). Definitions in the Vehicles Act are adopted unless the contrary intention appears (s 2(2)).

It interacts intimately with the MVWA(CI) Act 2016. Catastrophic injuries are removed from the common-law damages system and channelled into the CISS (ss 3EA, 3FB, 6A). The Commission’s premium assessment must now take account of CISS liabilities referable to motor vehicle injuries (s 3T(1A)). The definitions of “catastrophic injury”, “CISS”, “assessed treatment, care and support needs” and “treatment, care and support needs” are imported directly from the MVWA(CI) Act (s 3(1)).

The Workers Compensation and Injury Management Act 2023 intersects via s 3G. Where an injury gives rise to workers’ compensation liability, the Act and the policy do not cover the owner’s liability for negligence other than negligent driving. Section 3C(7) preserves the operation of that Act’s damages limitations.

The Insurance Commission of Western Australia Act 1986 continues the Commission, establishes the Third Party Insurance Fund, and confers additional powers (ss 3, 3S). Actuarial reporting and premium-setting processes cross-reference the Commission’s funds (s 3T(2)).

The District Court of Western Australia Act 1969 and Supreme Court rules govern jurisdiction and procedure. The abolition of the former Third Party Claims Tribunal in 1972 transferred jurisdiction to the ordinary courts with transitional savings (s 16).

Interstate recognition is facilitated by s 3(4), which exempts visiting motorists from prescribed jurisdictions that have “substantially similar” legislation. Section 3FA ensures that Western Australian damage caps travel with the substantive law even when another Australian court hears the claim.

The Sentencing Act 1995 (s 105) and Road Traffic (Authorisation to Drive) Act 2008 interact with the disqualification powers in ss 4(4) and 18.

The most significant recent amendments were introduced by the Motor Vehicle (Catastrophic Injuries) Act 2016, which commenced on 14 May 2016. That Act inserted ss 3EA, 3FA, 3FB and 6A, amended the definition section, and added transitional provisions (s 34). The purpose was to remove the most seriously injured claimants from the fault-based damages system and place them on a no-fault lifetime care scheme funded through the same premium pool. This reduced long-term liabilities for the Fund, stabilised premiums and provided certainty of care for catastrophically injured persons.

The Workers Compensation and Injury Management Act 2023 (commencing 1 July 2024) updated cross-references throughout (ss 3C(7), 3G, 3EA, 3FB) but did not alter the substantive operation of the motor-vehicle scheme.

Earlier, the Motor Vehicle (Third Party Insurance) Amendment Act 2006 inserted the earning-capacity cap (s 3F) and the employer-liability clarification (s 3G) to control rising claims costs, particularly large future-economic-loss awards.

The 1994 amendments (Act No 17 of 1994) introduced the original non-pecuniary loss thresholds and gratuitous-services restrictions (ss 3A–3E) in response to a perceived “compensation culture” and rapidly increasing premiums. Annual indexation machinery was added to keep thresholds aligned with wages.

Section 21 (extension of policy cover during short licence-renewal grace periods) was inserted in 2016 to address administrative anomalies after the move to integrated licensing.

These changes reflect a consistent legislative policy of containing the cost of compulsory insurance while maintaining a safety net for injured persons. Each round of reform has been driven by actuarial advice that the Fund faced unsustainable liabilities.

Although the Act itself has not generated a large body of constitutional litigation, its damages caps have been tested in the Supreme Court and Court of Appeal on questions of construction and application. The indexed thresholds in s 3C have required repeated judicial calculation of “most extreme case” valuations; courts have emphasised that only the gravest injuries attract Amount A (see the statutory text itself at s 3C(3)).

The interaction between the Act and the MVWA(CI) Act has produced disputes about whether a particular injury meets the statutory definition of “catastrophic injury” and whether a person remains an “interim participant” for the purposes of the s 3EA bar on damages. Section 3FA’s declaration that the restrictive provisions are substantive law has been invoked to resist enforcement of interstate judgments that ignore the Western Australian caps.

Controversy has surrounded the Commission’s recovery rights under ss 7(5) and 15. Insured persons have argued that the Commission must act reasonably when deciding whether to settle or defend claims; the proviso in s 7(5) limits the Commission’s recovery where it unreasonably refuses a settlement request. Courts have read this as importing an objective standard of reasonableness.

The prohibition on soliciting instructions (s 27) and the costs scale (s 27A) have been criticised by plaintiff lawyers as restricting access to justice, yet the provisions have been upheld as valid regulation of the claims industry.

The abolition of the specialist Third Party Claims Tribunal in 1972 and the transfer of jurisdiction to the District Court generated transitional litigation about practice and procedure (s 16(5)–(6)). More recently, the shift to the CISS has raised questions about the extent to which common-law damages for gratuitous services are truly extinguished (s 3EA(2) expressly includes them).

No High Court challenge has struck down the scheme, and the courts have consistently treated the damage limitations as a legitimate exercise of the State’s power to regulate the compulsory-insurance bargain.

Most practitioners assume that once a policy is issued the Commission’s liability is absolute. Section 7(4) removes many traditional policy defences, but the Commission retains a statutory right of recovery from the insured under s 7(5) where mis-statement, non-disclosure or breach of warranty has occurred. The “reasonableness” proviso is often overlooked; an insured who makes a timely written settlement request can limit the Commission’s recourse.

The s 3F earning-capacity cap is calculated at the date of award, not the date of injury. In long-tail claims the cap can therefore bite harder than expected. Few realise that the cap applies to both past and future economic loss and that “average weekly earnings” is defined by reference to the most recent Australian Statistician figure available to the court.

Section 3EA is a trap for the unwary: even if a person exits the CISS as an interim participant and never becomes a lifetime participant, damages for treatment, care and support needs during the interim period are permanently barred, whether or not the Commission actually paid for those services and whether or not they were provided gratuitously.

The notice-of-claim requirement in s 29(1) is not satisfied by mere correspondence; the regulations prescribe a particular form. Failure to comply bars the action unless the court grants leave under s 29A. Courts have been relatively generous where there is no prejudice, but late notice can still lead to contested satellite litigation.

The integration of the policy with the vehicle licence (s 4(8A)) means that a lapsed licence automatically renders the vehicle uninsured after the 15-day grace period in s 21. Many fleet operators have been caught by short administrative delays.

Finally, the “most extreme case” test in s 3C(3) is not a tariff; each case must be assessed on its own facts against the statutory maximum. Appellate courts have warned against mechanical application of percentages.

Vehicle owners must ensure that, before or at the time a vehicle licence is granted or renewed, the appropriate premium is paid to the Director General (s 4(8)). The licence document itself will contain the statutory explanation of cover. Owners should retain evidence of insurance and produce it to police on request (s 4(7A)–(7B)).

Drivers must carry their licence and be aware that they are covered only while the policy remains in force. Any accident causing injury must be reported to the Commission “forthwith” with full particulars (s 10(1)).

Claims professionals and lawyers must give written notice of intention to claim “as soon as practicable” using the prescribed form (s 29(1)). Late notice should be accompanied by an immediate application under s 29A if proceedings are contemplated. When acting for a claimant, do not enter costs agreements exceeding the applicable scale (s 27A) and avoid any conduct that could be characterised as soliciting instructions (s 27).

Insured persons faced with a claim must immediately notify the Commission and must not admit liability, settle or incur expense without written consent (s 10(5)). All correspondence should be forwarded to the Commission, which will assume conduct of the defence (s 11).

Fleet operators and employers should verify that every vehicle is licensed and insured and should obtain written acknowledgments from employees that private use is outside policy cover where appropriate. Where an employee’s vehicle is regularly used in business with the employer’s knowledge, the policy will extend to the employer (s 22(1)); this should be factored into risk assessments.

Medical and allied health practitioners providing emergency treatment should give written notice to the Commission within one month (s 12(1)(b)) to secure payment of their charges.

The Commission must undertake annual actuarial reviews (s 3T(2)), submit premium recommendations to the Minister, and publish Gazette notices of the indexed Amounts A–D by 1 July each year (ss 3C(11), 3D(10)). Claims handlers must comply with the statutory time limits for notice and must act reasonably when an insured requests settlement within policy limits.

All parties should maintain detailed records of notifications, as the Commission’s direct liability under s 7(1) is conditional on it having knowledge of the action before hearing in certain cases (s 7(1A), 8(1B)).

Compliance is best achieved by integrating insurance checks into licensing workflows, training drivers and managers on post-accident protocols, and seeking early legal advice on the interaction between the Act, the MVWA(CI) Act and workers’ compensation legislation. Regular review of the latest Gazette notices for the indexed thresholds is essential for accurate quantum advice.
