Fault in a motor vehicle accident is a legal finding that a driver was negligent under Queensland law and that the negligence caused the collision and the injured person's injuries. Fault is not determined by who apologised at the scene, who received a traffic infringement, or who the police officer believed was responsible. Fault is determined by applying the legal test of negligence set out in the Civil Liability Act 2003 (Qld) to the evidence of how the motor vehicle accident occurred.
The fault determination process in a motor vehicle accident begins when the injured person lodges a Notice of Accident Claim Form with the at-fault driver's Compulsory Third Party (CTP) insurer. The CTP insurer investigates the motor vehicle accident, reviews the available evidence, and issues a liability notice accepting or denying fault. The CTP insurer's decision is not final. A fault denial can be challenged through additional evidence, a compulsory conference, or court proceedings where a judge makes the binding determination. Research commissioned by the Motor Accident Insurance Commission found that claimants represented by a personal injury lawyer received an average settlement of $93,000 compared to $13,000 for unrepresented claimants.
Each type of motor vehicle accident produces a recognisable fault pattern based on the Queensland Road Rules that applied to the situation. Rear-end collisions, T-bone collisions, head-on collisions, roundabout collisions, and lane change collisions each carry a default fault presumption that the CTP insurer uses as the starting point for its analysis. Fault in a motor vehicle accident can be shared between both drivers. Where the injured person's own actions contributed to the motor vehicle accident or to the severity of the injuries, the CTP insurer applies contributory negligence and reduces the compensation by the percentage of fault attributed to the claimant.
A motor vehicle accident involving an unidentified or uninsured driver is handled through the Nominal Defendant, a government entity that acts as the insurer of last resort under the Motor Accident Insurance Act 1994 (Qld). Claims against the Nominal Defendant have shorter lodgement deadlines than standard CTP claims. The entire motor vehicle accident compensation claims process, from lodgement through to settlement or court judgment, depends on establishing fault as the threshold question.
What does fault mean in a motor vehicle accident?
Fault in a motor vehicle accident means a driver was negligent, and that negligence caused the collision and the claimant's injuries. Negligence is a legal concept with a specific meaning in Queensland personal injury law. A driver is negligent when they owe a duty of care to other road users, they breach that duty by failing to drive safely, that breach causes an accident, and the accident causes compensable injuries. All four elements must be established for fault to exist.
Every driver on Queensland roads owes a duty of care to every other road user - other drivers, passengers, pedestrians, cyclists, and motorcyclists. That duty requires the driver to comply with the Queensland Road Rules, maintain a proper lookout, keep a safe following distance, adjust their driving to the conditions, and take reasonable care to avoid causing harm. The duty of care is not limited to avoiding deliberate acts. A momentary lapse in concentration, a failure to check a blind spot, or a misjudgment of distance is enough to constitute a breach if a reasonable driver in the same circumstances would have acted differently.
The legal framework governing fault in motor vehicle accidents in Queensland is the Civil Liability Act 2003 (Qld), which sets out the test for negligence, the standard of care, and the rules for contributory negligence. The Queensland Road Rules, prescribed under the Transport Operations (Road Use Management - Road Rules) Regulation 2009 (Qld), define the specific obligations every driver must follow. A breach of the road rules is strong evidence of fault, but fault is ultimately a legal assessment of negligence made by reference to all of the circumstances of the accident - not just whether a road rule was broken.
Fault is a legal conclusion, not a moral judgment. A driver who made an honest mistake is still at fault if that mistake fell below the standard of care expected of a reasonable driver. Fault can also be shared between multiple drivers where both contributed to the accident or to the severity of the injuries.
How is fault defined in a motor vehicle accident compensation claim?
Fault in a motor vehicle accident compensation claim is defined by the legal test of negligence, representing a failure to take reasonable care to avoid causing injury or loss to another person. Under the Civil Liability Act 2003 (Qld), negligence consists of 4 elements (duty of care, breach of duty, causation, and damage) which must all be present to establish fault after a road accident.
More information on the 4 elements of negligence required to establish fault in a motor vehicle accident claim is outlined below.
- Duty of care: Every driver on Queensland roads owes a duty of care to every other road user. That duty requires the driver to take reasonable care to avoid causing harm to other drivers, passengers, pedestrians, cyclists, and motorcyclists
- Breach of duty: A breach occurs when the driver fails to meet the standard of care expected of a reasonable driver in the same circumstances. Running a red light, tailgating, speeding, and driving while distracted are all examples of a breach of the duty of care. In a motor vehicle accident, the Queensland Road Rules provide the primary benchmark for assessing whether a driver breached their duty of care
- Causation: The breach must have caused the accident. The standard test is whether the accident would have occurred "but for" the driver's breach. A driver who ran a red light but would have been hit regardless by a vehicle running the cross street may not satisfy the causation element
- Damage: The accident must have caused compensable injuries or losses. A breach that caused a collision but no injury does not give rise to a fault-based compensation claim under the CTP scheme
The same 4 elements apply across all personal injury claim types in Queensland, not just motor vehicle accidents. A personal injury claim is a legal process that allows an injured person to seek financial compensation for physical or psychological harm caused by another party's negligence. The motor vehicle accident fault determination is one application of that broader negligence framework, with the Queensland Road Rules providing the specific benchmark against which a driver's conduct is measured.
Does breaking a road rule automatically mean you are at fault?
No, breaking a road rule does not automatically mean you are at fault in a motor vehicle accident, but it is evidence that you potentially breached your duty of care as a driver. The CTP insurer and the court treat a road rule breach as a significant factor in the fault assessment, but fault is ultimately determined by looking at all of the circumstances of the motor vehicle accident.
For example, a driver who ran a red light and caused a collision will almost certainly be found at fault because the breach of the road rule is directly connected to the motor vehicle accident. A driver who was slightly exceeding the speed limit but was struck by another vehicle that failed to give way may not be at fault for the collision itself, even though they breached a road rule. The fault determination in a motor vehicle accident turns on whether the road rule breach caused or materially contributed to the collision and the claimant's injuries, not simply whether a breach occurred. The specific driving obligations that form the baseline for this assessment are the Queensland Road Rules prescribed under the Transport Operations (Road Use Management - Road Rules) Regulation 2009 (Qld).
A driver can also be found at fault in a motor vehicle accident without breaking any specific road rule. The Queensland Road Rules set a minimum standard of driving conduct, but the duty of care can require a higher standard depending on the conditions. A driver who was technically complying with the speed limit but was travelling too fast for wet roads, poor visibility, or a congested road environment may still have breached their duty of care in the motor vehicle accident. The test is what a reasonable driver would have done in the same circumstances, and that test can exceed what the road rules prescribe.
Who determines fault after a motor vehicle accident in Queensland?
Fault after a motor vehicle accident in Queensland is determined initially by the Compulsory Third Party (CTP) insurer of the at-fault vehicle, and finally by the court if the claim does not settle. These are two separate decision-makers applying the same legal test at different stages of the claim.
More information on the two parties who determine fault after a motor vehicle accident is outlined below.
- CTP insurer (initial determination): The Compulsory Third Party (CTP) insurer makes the first fault determination after the injured person lodges a claim. The insurer reviews the available evidence, assesses whether its insured driver was negligent, and issues a liability notice accepting or denying fault. That CTP insurer decision is not a final legal ruling - it is the insurer's assessment based on the evidence available at the time, and it can be challenged. The role of CTP insurance in Queensland is to fund compensation for people injured in motor vehicle accidents caused by the insured vehicle
- Court (final determination): The court makes the final fault determination if the claim proceeds to litigation. The court applies the balance of probabilities standard, meaning the claimant must show that it is more likely than not that the other driver was negligent. The court's fault determination is binding on both parties
Queensland Police do not determine fault for the purpose of a motor vehicle accident compensation claim. Police investigate whether any criminal traffic offences occurred, and the police report is an important piece of evidence in the fault assessment. A traffic infringement notice issued by police is strong evidence of a breach of the road rules, but a police finding is not the same as a determination of civil fault. The police role in the fault determination process is covered in detail below.
How does the CTP insurer determine fault after a motor vehicle accident?
The CTP insurer determines fault after a motor vehicle accident by investigating the circumstances of the accident, reviewing all available evidence, and assessing whether its insured driver breached their duty of care under Queensland law. The investigation is a structured process that begins when the injured person formally lodges a claim and ends when the insurer issues a liability notice stating whether fault is accepted, partially accepted, or denied.
The CTP insurer is not a neutral party in the fault determination. The insurer represents the at-fault driver's interests and pays the compensation from its own funds if fault is accepted. That financial interest means the insurer's investigation is focused on minimising its exposure - testing whether the evidence genuinely supports the claim, whether the claimant contributed to the accident, and whether the injuries claimed were actually caused by the collision.
Legal representation significantly affects the outcome of a CTP insurer's fault determination. Research commissioned by the Motor Accident Insurance Commission (MAIC) found that claimants represented by a lawyer received an average settlement of $93,000 compared to $13,000 for unrepresented claimants. A lawyer ensures that the insurer's assessment is based on the full body of evidence, not just the evidence that favours the insurer's position, and challenges any attempt to deny or reduce liability without proper justification.
What triggers the CTP insurer's fault investigation after a motor vehicle accident?
The CTP insurer's fault investigation after a motor vehicle accident is triggered by the lodgement of a Notice of Accident Claim Form with the at-fault vehicle's CTP insurer. The Notice of Accident Claim Form is the formal document that begins the CTP claim process. The form is a sworn declaration that provides details of the motor vehicle accident, the injuries sustained, the medical treatment received, and the identity of the at-fault driver and their vehicle.
The CTP insurer has no obligation to investigate a motor vehicle accident until the Notice of Accident Claim Form is lodged. Once lodged, the CTP insurer is required under the Motor Accident Insurance Act 1994 to investigate the claim within statutory timeframes and issue a liability notice responding to the claim. The CTP insurer will typically request additional information during the investigation, including the police report, medical records, and in some cases a recorded statement from the claimant.
Early lodgement of a motor vehicle accident claim benefits the claimant in two ways. The evidence is fresher and more complete closer to the date of the accident. The CTP insurer is also obligated to fund reasonable medical treatment and rehabilitation once the claim is lodged and liability is accepted, which means the claimant does not have to pay for ongoing treatment out of pocket while the fault determination is being made.
The Notice of Accident Claim Form must be lodged within strict deadlines. The standard deadline is 9 months from the date of the motor vehicle accident or 1 month after first consulting a lawyer, whichever comes first. Different time limits for car accident claims in Queensland apply depending on the circumstances, and claims involving uninsured, unregistered, or unidentified vehicles have significantly shorter deadlines.
What is the CTP insurer's response to the notice of claim?
The CTP insurer's response to the notice of claim is the formal written response issued by the CTP insurer after completing its fault investigation into a motor vehicle accident claim. The response is required under section 39 of the Motor Accident Insurance Act 1994 and must be issued within the statutory timeframe after the Notice of Accident Claim Form is lodged.
The CTP insurer's response communicates 1 of 3 outcomes for the fault determination, as outlined below.
- (Option 1) Liability accepted: The CTP insurer accepts that its insured driver was at fault for the motor vehicle accident and agrees to pay compensation for the claimant's injuries. The CTP insurer is then obligated to fund reasonable medical treatment and rehabilitation while the claim is ongoing
- (Option 2) Liability accepted with contributory negligence: The CTP insurer accepts that its insured driver was at fault but asserts that the claimant's own actions contributed to the motor vehicle accident or to the severity of the injuries. The compensation is reduced by the percentage of fault attributed to the claimant
- (Option 3) Liability denied: The CTP insurer denies that its insured driver was at fault for the motor vehicle accident. The insurer must provide reasons for the denial. A denial does not end the claim - the claimant can dispute the CTP insurer's decision through further evidence, a compulsory conference, or court proceedings
The CTP insurer's response to the notice of claim is not a final legal determination of fault. It is the CTP insurer's position based on the evidence reviewed during the investigation. That position can change if new evidence emerges, and it can be overturned by a court if the motor vehicle accident claim proceeds to litigation.
What evidence is used to determine fault in a motor vehicle accident?
The evidence used to determine fault in a motor vehicle accident includes the police report, dashcam and CCTV footage, witness statements, vehicle damage analysis, medical records, and in complex cases, accident reconstruction expert reports. The CTP insurer reviews all available evidence to establish how the motor vehicle accident occurred, which driver breached their duty of care, and whether that breach caused the claimant's injuries.
No single piece of evidence determines fault on its own. The CTP insurer builds a picture of the motor vehicle accident by combining multiple evidence sources, each of which contributes a different perspective on what happened. The strongest fault determinations are supported by independent evidence that corroborates the claimant's version of events.
There are 8 types of evidence commonly used in motor vehicle accident fault determinations.
- Police report: The police report records the details of the drivers, vehicles, scene description, and any traffic offences identified by the attending officer. The police report is the foundation of most fault determinations because it is created by an independent party shortly after the motor vehicle accident
- Dashcam and CCTV footage: Video footage is the most objective form of evidence in a motor vehicle accident fault determination because it records what happened without relying on memory or interpretation. Dashcam footage from the vehicles involved and CCTV footage from nearby buildings, service stations, or traffic cameras can confirm or contradict the accounts given by each driver
- Witness statements: Independent witnesses who observed the motor vehicle accident provide accounts that are not influenced by a personal stake in the outcome. Witness statements are particularly valuable when the drivers give conflicting versions of how the motor vehicle accident occurred
- Vehicle damage analysis: The location, direction, and severity of damage to each vehicle involved in the motor vehicle accident reveals the angle of impact, the relative speed of the vehicles, and the point of collision. Vehicle damage patterns can confirm or contradict the accounts given by the drivers
- Medical records: Medical records document the nature and severity of the claimant's injuries and the mechanism of injury described to the treating doctor. The medical evidence links the injuries to the motor vehicle accident and helps establish whether the collision was forceful enough to cause the injuries claimed
- Accident reconstruction expert reports: An accident reconstruction expert analyses the physical evidence from the motor vehicle accident scene (skid marks, debris patterns, vehicle damage, road geometry) and produces a technical report on how the collision occurred. Accident reconstruction is typically used in complex or high-value motor vehicle accident claims where the physical evidence is ambiguous
- Mobile phone records: Mobile phone records can establish whether a driver was using their phone at the time of the motor vehicle accident. A call, text message, or app usage timestamped at the moment of collision is strong evidence of distracted driving
- Blood alcohol and drug test results: Blood alcohol concentration and drug test results taken by police after a motor vehicle accident establish whether a driver was impaired at the time of the collision. Impairment is strong evidence of a breach of the duty of care
How do insurers assess conflicting evidence in a motor vehicle accident fault determination?
When the evidence in a motor vehicle accident fault determination is conflicting, the Compulsory Third Party (CTP) insurer assesses the reliability, independence, and consistency of each piece of evidence to determine which version of events is more likely to be accurate. Conflicting evidence is common in motor vehicle accident claims because each driver has a personal interest in presenting their version of events favourably.
Independent evidence carries more weight than evidence from the parties involved. Dashcam footage, CCTV recordings, and traffic light camera records are treated as the most reliable evidence in a motor vehicle accident fault determination because they are not influenced by memory, bias, or self-interest. Witness statements from people who have no connection to either driver are given more weight than statements from passengers or family members.
Physical evidence is assessed against the accounts given by each driver. The vehicle damage patterns, skid mark locations, and debris field in a motor vehicle accident must be consistent with the driver's description of how the collision occurred. A driver who claims they were stationary when hit, but whose vehicle shows damage consistent with forward movement at speed, faces a credibility problem that weakens their entire account.
Where the evidence is evenly balanced and fault cannot be determined conclusively, the CTP insurer may deny liability and leave the fault determination to the court. The court applies the balance of probabilities standard, meaning the claimant must show that it is more likely than not that the other driver was at fault. A finding of 51% probability is sufficient.
What role do police play in determining fault after a motor vehicle accident?
Queensland Police do not determine civil fault for the purpose of a motor vehicle accident compensation claim. Police investigate whether any criminal traffic offences occurred at the scene of the motor vehicle accident, and the police report is an important piece of evidence in the fault assessment. However, the police investigation and the civil fault determination are two separate processes governed by different legal standards.
Police assess whether a driver committed a traffic offence under the Queensland Road Rules, such as running a red light, exceeding the speed limit, or driving under the influence of alcohol or drugs. A traffic infringement notice issued by police after a motor vehicle accident is strong evidence that the driver breached their duty of care, but it is not the same as a finding of civil fault. The Compulsory Third Party (CTP) insurer and the court make the civil fault determination separately by applying the negligence test under the Civil Liability Act 2003 (Qld).
The police report remains one of the most important pieces of evidence in a motor vehicle accident fault determination. The report records the details of the drivers, vehicles, road conditions, witness accounts, and any offences identified at the scene. The police report is created by an independent party shortly after the motor vehicle accident, which gives it significant evidentiary weight compared to accounts provided by the drivers themselves weeks or months later.
Can you be found at fault without being charged with a traffic offence?
Yes, you can be found at fault in a motor vehicle accident compensation claim without being charged with any traffic offence. The criminal standard for charging a driver with a traffic offence is higher than the civil standard for establishing fault in a compensation claim. Police may decline to issue an infringement notice because the evidence does not meet the criminal threshold, while the CTP insurer or the court may still find fault on the balance of probabilities.
A common example is a motor vehicle accident at an uncontrolled intersection where both drivers claim they had right of way. Police may attend the scene and determine that there is insufficient evidence to charge either driver with failing to give way. The CTP insurer can still assess the available evidence (vehicle damage patterns, witness statements, road layout) and conclude that one driver was more likely at fault than the other.
The reverse is also true. A driver who is charged with a traffic offence after a motor vehicle accident is not automatically found at fault for the purpose of a compensation claim. A speeding infringement, for example, does not establish civil fault if the speed was not a contributing factor in the motor vehicle accident. The CTP insurer must still establish that the breach of the road rule caused or contributed to the collision and the claimant's injuries.
How is fault determined in common types of motor vehicle accidents?
Fault in common types of motor vehicle accidents is determined by applying the negligence test to the specific road rules and driving obligations that govern each accident scenario. Each motor vehicle accident type has a default fault presumption based on the Queensland Road Rules that applied to the situation. The presumption identifies which driver is most likely at fault based on the collision mechanic, but it is a starting point for the CTP insurer's fault analysis rather than an automatic conclusion.
The 7 most common car accident types each produce a recognisable fault pattern in a motor vehicle accident.
- Rear-end collisions: Fault in a rear-end collision is presumed to rest with the driver of the rear vehicle because every driver has a legal obligation to maintain a safe following distance from the vehicle ahead. The fault presumption can shift where the lead vehicle reversed unexpectedly, changed lanes into a gap that was too short, or had no functioning brake lights
- T-bone collisions at intersections: Fault in a T-bone collision at an intersection is attributed to the driver who failed to obey the traffic control or give way rule governing the intersection. The fault determination becomes contested where both drivers claim to have entered on a green light, or at uncontrolled intersections where the give way to the right rule applies
- Head-on collisions: Fault in a head-on collision is presumed to rest with the driver who crossed onto the wrong side of the road. The fault presumption is strong because a driver has no legitimate reason to be in the opposing lane unless overtaking where permitted. Fault can be disputed where road conditions or a third vehicle forced evasive action
- Roundabout collisions: Fault in a roundabout collision is attributed to the driver entering the roundabout without giving way to vehicles already circulating. Fault disputes in roundabout collisions arise where a circulating driver changed lanes without indicating, or where two vehicles exited a multi-lane roundabout into the same lane
- Lane change and sideswipe collisions: Fault in a lane change or sideswipe collision is presumed to rest with the driver who initiated the lane change because a lane-changing driver must give way to any vehicle already in the target lane. Fault in a sideswipe collision can be shared where both vehicles changed lanes simultaneously into the same space
- Reversing collisions: Fault in a reversing collision rests almost always with the reversing driver because a reversing driver must ensure the path behind the vehicle is clear before and during the manoeuvre. The fault presumption can shift where the other vehicle or pedestrian moved into the reversing path after the manoeuvre had commenced
- Multi-vehicle collisions: Fault in a multi-vehicle collision is assessed against each driver individually based on their contribution to the collision sequence. A driver who was stationary or travelling safely and was pushed into the vehicle ahead by a rear impact is not at fault for the forward collision. Fault in a multi-vehicle collision can be distributed across multiple drivers in different proportions
What happens if both drivers are at fault in a motor vehicle accident?
Where both drivers are at fault in a motor vehicle accident, the compensation is reduced by the percentage of fault attributed to the claimant rather than denied entirely. This principle is called contributory negligence. A claimant who is found 20% at fault for the motor vehicle accident receives 80% of the total compensation. A claimant who is found 50% at fault receives 50%. The percentage is assessed by the Compulsory Third Party (CTP) insurer during the fault determination, or by the court if the claim proceeds to litigation.
Contributory negligence does not change who the at-fault driver is for the purpose of the CTP claim. The claimant still lodges the claim against the other driver's CTP insurer, and the other driver is still found at fault for causing the motor vehicle accident. The contributory negligence finding reduces the compensation paid, but the CTP insurer remains liable for the reduced amount. A claimant who contributed to the motor vehicle accident is not required to make a separate claim against their own CTP insurer. The rules governing contributory negligence in Queensland are set out in sections 23 and 24 of the Civil Liability Act 2003 (Qld).
The CTP insurer assesses contributory negligence as part of the same fault investigation that determines primary liability. The CTP insurer reviews the evidence to decide whether the claimant's own actions fell below the standard of care expected of a reasonable road user, and whether those actions contributed to the motor vehicle accident or to the severity of the injuries. The contributory negligence percentage is stated in the CTP insurer's liability notice alongside the primary fault finding.
What are the most common examples of contributory negligence in motor vehicle accidents?
The most common examples of contributory negligence in motor vehicle accidents are not wearing a seatbelt, speeding at the time of the collision, failing to keep a proper lookout, and drink driving or travelling with an intoxicated driver.
There are 4 examples of contributory negligence that arise frequently in motor vehicle accident fault determinations.
- Not wearing a seatbelt: Failure to wear a seatbelt does not cause the motor vehicle accident, but it increases the severity of the injuries sustained. The CTP insurer reduces the compensation to reflect the additional injuries that would not have occurred if the claimant had been wearing a seatbelt at the time of the collision.
- Speeding at the time of the collision: A claimant who was exceeding the speed limit at the time of the motor vehicle accident may be found partly at fault even where the other driver caused the collision. The speeding contributed to the severity of the impact or reduced the claimant's ability to take evasive action.
- Failing to keep a proper lookout: A claimant who was distracted, using a mobile phone, or otherwise not paying attention to the road may be found partly at fault for failing to see and avoid the collision. The CTP insurer assesses whether a reasonable driver in the same position would have been able to take evasive action.
- Drink driving or travelling with an intoxicated driver: A claimant who was driving while intoxicated can have their compensation reduced where the intoxication contributed to the motor vehicle accident or to the severity of the injuries. A driver whose blood alcohol concentration exceeded the legal limit has a reduced capacity to react, and that impairment is treated as a failure to take reasonable care even where the other driver was primarily at fault. A passenger who voluntarily travelled with a driver they knew or should have known was intoxicated can also have their compensation reduced for accepting the risk.
What happens if the CTP insurer denies fault?
A fault denial by the Compulsory Third Party (CTP) insurer means the insurer has assessed the evidence and concluded that its insured driver was not at fault for the motor vehicle accident, and the insurer will not pay compensation on the claim. A fault denial does not end the claim. The claimant can dispute the CTP insurer's decision by obtaining further evidence, requesting a compulsory conference, or commencing court proceedings to have the fault determination decided by a judge.
The CTP insurer must provide written reasons for the fault denial in its liability notice. The reasons identify the evidence the CTP insurer relied on and explain why the insurer concluded that its insured driver did not breach their duty of care or that the breach did not cause the motor vehicle accident. The written reasons are important because they reveal the specific gaps or weaknesses in the claimant's case that need to be addressed to challenge the denial.
A fault denial is the CTP insurer's position on liability, not a legal finding. The CTP insurer is not a court and does not have the authority to make a binding determination of fault. The insurer's denial reflects its assessment of the evidence available at the time, and that assessment can be wrong - particularly where the CTP insurer did not have access to all relevant evidence, relied on its insured driver's account without independent corroboration, or applied an unreasonable interpretation of the road rules to the circumstances of the motor vehicle accident.
How do you challenge a CTP insurer's liability decision?
A CTP insurer's liability decision is challenged by obtaining additional evidence that addresses the reasons for the denial, then escalating the dispute through a compulsory conference or court proceedings. The challenge process has 3 stages, and a motor vehicle accident claim can resolve at any stage.
- Gather additional evidence to address the denial: The first step is to identify what evidence the CTP insurer relied on to deny fault and what evidence is missing. A denial based on conflicting driver accounts can be challenged by obtaining independent witness statements, dashcam footage, CCTV recordings, or an accident reconstruction report that supports the claimant's version of events. A denial based on the claimant's alleged contributory negligence can be challenged by evidence showing the claimant's actions did not cause or contribute to the motor vehicle accident.
- Request a compulsory conference: A compulsory conference is a mandatory settlement meeting between the claimant's personal injury lawyer and the CTP insurer, required under the Motor Accident Insurance Act 1994 (Qld) before court proceedings can commence. The compulsory conference gives the claimant's personal injury lawyer an opportunity to present the additional evidence directly to the CTP insurer and negotiate a resolution. Many fault denials are reversed or revised at the compulsory conference stage when the CTP insurer is confronted with evidence it did not have during the initial investigation.
- Commence court proceedings: The claimant can file court proceedings if the CTP insurer maintains its fault denial after the compulsory conference. The court makes the final determination of fault by applying the balance of probabilities standard, meaning the claimant must show it is more likely than not that the other driver was negligent. The court's fault determination is binding on both parties and overrides the CTP insurer's denial.
How is fault determined when the other driver cannot be identified?
Fault when the other driver cannot be identified is determined through the same negligence test that applies to all motor vehicle accident claims, but the claim is lodged against the Nominal Defendant, a government entity that acts as the insurer of last resort (instead of the missing CTP insurer). The claimant must still establish that an unidentified driver was negligent and that the negligence caused the collision and the injuries. In Queensland, the available evidence (the police report, witness statements, dashcam footage, and vehicle damage analysis) is used to reconstruct how the motor vehicle accident occurred and establish that a second vehicle was involved.
The Nominal Defendant is established under the Motor Accident Insurance Act 1994 (Qld) and investigates the claim and assesses fault in the same way a CTP insurer would. The claimant faces a higher evidentiary burden in practice because they must prove the unidentified vehicle existed and caused the collision. The Nominal Defendant will scrutinise whether the motor vehicle accident was genuinely caused by another vehicle or whether it was a single-vehicle accident. Independent evidence such as vehicle damage patterns consistent with a two-vehicle collision, paint transfer from the other vehicle, and witness statements are critical to establishing that an unidentified driver was at fault.
Claims against the Nominal Defendant have shorter lodgement deadlines than standard CTP claims. The Notice of Accident Claim Form must be lodged within 3 months of the motor vehicle accident, compared to the standard 9 month deadline. The shorter deadline exists because evidence of the unidentified vehicle's involvement deteriorates rapidly, and early investigation gives the Nominal Defendant the best chance of identifying the at-fault vehicle.
What evidence should you collect to help prove fault after a motor vehicle accident?
The evidence you should collect to help prove fault after a motor vehicle accident includes photos of the accident scene and vehicle damage, the other driver's details and registration number, witness contact information, and dashcam footage. The evidence that strengthens a fault determination is the same evidence the claimant should prioritise collecting at the scene of the motor vehicle accident. The quality and completeness of the evidence gathered immediately after the collision directly affects the Compulsory Third Party (CTP) insurer's ability to determine which driver was at fault.
Collecting evidence at the scene is the single most effective thing a claimant can do to support the fault determination in a motor vehicle accident. The most important steps to take after a car accident for evidence collection are photographing the vehicle damage and road layout before anything is moved, exchanging details with the other driver, noting the names and phone numbers of independent witnesses, and saving any dashcam footage before it is overwritten. A written account of exactly what happened should be recorded as soon as possible after the motor vehicle accident while the details are fresh, because evidence that is not preserved at the scene is often impossible to recover later.
Can you claim compensation if you are not at fault in a motor vehicle accident?
Yes, a claimant who is not at fault in a motor vehicle accident is entitled to claim full compensation for their injuries through the at-fault driver's Compulsory Third Party (CTP) insurance. The fault determination establishes that the other driver was negligent, and the CTP insurer of the at-fault vehicle is liable for the claimant's compensation. The claimant does not need to have their own CTP insurance or any other insurance to make the claim.
The claim follows the same process as any other motor vehicle accident compensation claim. The claimant lodges a Notice of Accident Claim Form with the at-fault driver's CTP insurer, the CTP insurer investigates and issues a liability notice, and the claim is resolved through negotiation, a compulsory conference, or court proceedings. A claimant involved in a not-at-fault car accident receives 100% of their assessed compensation with no reduction for contributory negligence.
How many motor vehicle accidents happen in Queensland each year?
Queensland records approximately 20,000 to 30,000 police-reported road crashes per year, including crashes causing property damage, injury, and death. In 2024, 302 people were killed in road crashes in Queensland according to Queensland Government Transport and Main Roads data. Not all of these crashes result in a CTP compensation claim, because the CTP scheme only covers claims where another driver was at fault and the claimant sustained a personal injury.
The most common motor vehicle accident types involved in fault disputes are rear-end collisions, intersection collisions, and roundabout collisions, because these are the scenarios where the give way rules and following distance obligations are most frequently breached. Queensland road accident statistics broken down by crash type, location, and driver demographics show that young drivers aged 17 to 24 and provisional licence holders are the most overrepresented group in casualty crash data.
