Contributory Negligence in Queensland Personal Injury Claims

Contributory negligence is a legal principle in Queensland personal injury law that reduces the compensation a claimant receives when the claimant's own actions contributed to the accident or worsened the injuries. Contributory negligence does not prevent a claim from being made. A claimant who is found partly at fault still receives compensation, reduced by the percentage of fault attributed to them. For example, a claimant found 30% at fault for a motor vehicle accident receives 70% of the total assessed compensation.

The most common examples of contributory negligence in motor vehicle accident claims are not wearing a seatbelt, speeding, failing to keep a proper lookout, and driving or travelling with a driver who is intoxicated. The Civil Liability Act 2003 (Qld) imposes statutory presumptions of contributory negligence for intoxication, with a minimum 25% reduction for intoxicated drivers and passengers who travel with an intoxicated driver, increasing to a minimum 50% reduction where the driver's blood alcohol concentration was 0.15 or above.

The onus of proving contributory negligence rests on the defendant. In a motor vehicle accident compensation claim, the Compulsory Third Party (CTP) insurer of the at-fault vehicle must prove on the balance of probabilities that the claimant failed to take reasonable care and that the failure contributed to the accident or the injuries. The CTP insurer states the contributory negligence percentage in its liability notice, and the claimant can accept or dispute that percentage through negotiation, a compulsory conference, or court proceedings.

Contributory negligence can defeat a claim entirely in Queensland under section 24 of the Civil Liability Act 2003 (Qld), which allows the court to reduce compensation to zero if the claimant is found 100% responsible. Contributory negligence applies across all personal injury claims, including motor vehicle accidents, workplace injuries, public liability claims, and medical negligence claims. Children under 5 cannot be found contributorily negligent, and children aged 5 and above are assessed against the standard of a reasonable child of the same age.

What is contributory negligence?

Contributory negligence means your compensation is reduced by the percentage of fault attributed to you, but you do not lose the right to claim. A claimant who is found partly at fault for a motor vehicle accident still receives compensation through the at-fault driver's Compulsory Third Party (CTP) insurer. For example, a claimant found 20% at fault receives 80% of the total compensation, and a claimant found 50% at fault receives 50%.

Contributory negligence does not mean the claimant caused the accident. It means the claimant's actions fell below the standard of care expected of a reasonable person in the same circumstances, and those actions played a role in what happened or how badly the claimant was hurt. Common examples of contributory negligence in motor vehicle accidents include not wearing a seatbelt, speeding at the time of the collision, driving while intoxicated, and travelling as a passenger with a driver the claimant knew was intoxicated.

Contributory negligence is a defence raised by the defendant. In a motor vehicle accident compensation claim, the Compulsory Third Party (CTP) insurer of the at-fault vehicle asserts contributory negligence if the evidence shows that the claimant's own conduct contributed to the motor vehicle accident or worsened the injuries. The onus of proof for establishing contributory negligence is on the CTP insurer, which must prove it on the balance of probabilities. The claimant does not need to disprove contributory negligence.

The legal framework governing contributory negligence in Queensland is set out in section 10 of the Law Reform Act 1995 (Qld), which allows a court to reduce damages by an amount it considers fair and equitable having regard to the claimant's share of responsibility for the harm.

The Civil Liability Act 2003 (Qld) sections 23 and 24 set the standard of care for assessing contributory negligence and confirm that contributory negligence can defeat a claim entirely in Queensland if the claimant is found 100% responsible. Contributory negligence applies across all personal injury claim types, including motor vehicle accidents, workplace injuries, public liability claims, and medical negligence claims.

How does contributory negligence reduce compensation?

Contributory negligence reduces compensation by applying a percentage reduction to the total assessed damages that reflects the claimant's share of responsibility for the accident or the injuries. The contributory negligence percentage is assessed by the Compulsory Third Party (CTP) insurer during the fault investigation, or by the court if the claim proceeds to litigation. The contributory negligence reduction applies to the total compensation across all heads of damage, including general damages, economic loss, medical expenses, and care and assistance.

The motor vehicle accident claim is still lodged against the at-fault driver's CTP insurer. The other driver remains at fault for causing the motor vehicle accident, and the CTP insurer remains liable for paying the compensation. Contributory negligence only affects the amount the CTP insurer pays, not who pays it. The claimant does not need to make a separate claim against their own CTP insurer for the reduced portion.

The CTP insurer states the contributory negligence percentage in its liability notice alongside the primary fault finding. A liability notice that reads "liability accepted with 25% contributory negligence" means the CTP insurer accepts that its insured driver was at fault but asserts the claimant was 25% responsible for the motor vehicle accident, and the compensation will be reduced by 25%. The claimant can accept the contributory negligence percentage or dispute it through negotiation, a compulsory conference, or court proceedings. The process for how fault is determined in a motor vehicle accident governs both the primary liability finding and the contributory negligence assessment.

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, driving while intoxicated, and travelling as a passenger with a driver known to be intoxicated. Each example of contributory negligence involves the claimant failing to take reasonable care for their own safety in a way that contributed to the motor vehicle accident or worsened the injuries sustained.

There are 6 examples of contributory negligence that arise frequently in motor vehicle accident compensation claims, as outlined below.

• Not wearing a seatbelt: Not wearing a seatbelt does not cause the motor vehicle accident, but not wearing a seatbelt increases the severity of the injuries sustained in the collision. The Compulsory Third Party (CTP) insurer reduces the compensation to reflect the additional injuries that would not have occurred if the claimant had been wearing a seatbelt. Typical contributory negligence reductions for not wearing a seatbelt range from 10% to 25% depending on the circumstances.
• 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. Speeding increases the severity of the impact and reduces the claimant's ability to take evasive action. The contributory negligence percentage for speeding depends on how far the claimant exceeded the speed limit and how directly the speeding contributed to the motor vehicle accident.
• Failing to keep a proper lookout: A claimant who was distracted, using a mobile phone, or not paying attention to the road may be found partly at fault for failing to see and avoid the motor vehicle accident. The CTP insurer assesses whether a reasonable driver in the same position would have been able to take evasive action to avoid the collision.
• Driving while intoxicated: A claimant who was driving with a blood alcohol concentration above the legal limit has a reduced capacity to react, and that impairment is treated as a failure to take reasonable care. The Civil Liability Act 2003 (Qld) imposes a statutory presumption of contributory negligence for intoxicated drivers, with a minimum reduction of 25% and a minimum of 50% where the blood alcohol concentration is 0.15 or above.
• Travelling as a passenger with an intoxicated driver: A passenger who voluntarily travels with a driver they knew or should have known was intoxicated can have their compensation reduced for accepting the risk. The Civil Liability Act 2003 (Qld) section 48 imposes a statutory presumption of at least 25% contributory negligence for passengers who relied on the care and skill of a person they knew was intoxicated.
• Pedestrian entering the road without looking: A pedestrian who steps onto the road without checking for traffic may be found partly at fault for the motor vehicle accident. The contributory negligence percentage for a pedestrian depends on the circumstances, including the visibility, the speed of the traffic, and whether the pedestrian was at a designated crossing.

What is the statutory presumption of contributory negligence for intoxication?

The statutory presumption of contributory negligence for intoxication is a mandatory reduction in compensation that applies automatically when the claimant was intoxicated at the time of the motor vehicle accident and the intoxication contributed to the accident or the injuries. The presumption of contributory negligence for intoxication is set out in sections 47 and 48 of the Civil Liability Act 2003 (Qld) and shifts the onus onto the claimant to rebut it.

The statutory presumption of contributory negligence for intoxication applies in 2 circumstances.

• Intoxicated driver (minimum 25% reduction): An intoxicated driver's compensation is reduced by a minimum of 25%, increasing to a minimum of 50% where the driver's blood alcohol concentration was 0.15 or above or the driver was so affected by alcohol or drugs as to be incapable of exercising effective control of the vehicle. These minimum reductions for intoxicated driver contributory negligence are prescribed by section 47 of the Civil Liability Act 2003 (Qld). The court can impose a higher reduction than the minimum if the circumstances warrant it. The claimant can rebut the presumption of contributory negligence by proving that the intoxication did not contribute to the motor vehicle accident or to the severity of the injuries, but the practical reality is that most intoxicated drivers face a significant reduction in compensation.
• Passenger travelling with an intoxicated driver (minimum 25% reduction): A passenger who was at least 16 years old, relied on the care and skill of a driver who was intoxicated, and knew or ought to have known the driver was intoxicated faces a minimum 25% reduction in compensation under section 48 of the Civil Liability Act 2003 (Qld). The passenger can rebut the presumption of contributory negligence by proving they could not reasonably have been expected to avoid relying on the intoxicated driver's care and skill. A passenger in a remote location with no alternative transport may successfully rebut the presumption. A passenger who had other transport options available and chose to travel with a driver they knew had been drinking heavily is unlikely to rebut it. Section 48 specifically provides that the common law defence of voluntary assumption of risk does not apply where this statutory presumption of contributory negligence applies.

Can contributory negligence defeat a claim entirely in Queensland?

Yes, contributory negligence can defeat a claim entirely in Queensland if the claimant is found 100% responsible for the accident or the injuries sustained. Section 24 of the Civil Liability Act 2003 (Qld) confirms that contributory negligence is not limited to a partial reduction. The court can reduce the compensation to zero if the evidence establishes that the claimant's own negligence was wholly responsible for the harm.

This is a significant feature of Queensland's contributory negligence law. In some other Australian jurisdictions, contributory negligence can only reduce compensation, not eliminate it entirely. In Queensland, a defendant who proves that the claimant was entirely responsible for their own injuries can defeat the claim in full through a 100% contributory negligence finding.

A 100% contributory negligence finding is rare in motor vehicle accident claims because the claim is lodged against the other driver's Compulsory Third Party (CTP) insurer, which means another driver was involved and their conduct is also being assessed. A finding of 100% contributory negligence effectively means the other driver was not negligent at all, which is more accurately described as a liability denial rather than a contributory negligence finding. The practical significance of section 24 for contributory negligence is that it removes any floor on the reduction, meaning claimants with very high levels of fault (80%, 90%) cannot rely on a guaranteed minimum payout.

How is the percentage of contributory negligence determined?

The percentage of contributory negligence is determined by comparing the conduct of both parties and assessing how far each departed from their respective duty of care. The court considers the relative seriousness of each party's breach and the causal potency of each party's actions in contributing to the motor vehicle accident and the injuries sustained.

The assessment for determining contributory negligence (CN) is not a mathematical formula. The court examines the entire conduct of both parties leading up to the motor vehicle accident, not just the moment immediately before the collision. A driver who was speeding for 10 minutes before a motor vehicle accident is assessed on the full course of conduct, not just the final second of impact. The High Court of Australia confirmed this approach to contributory negligence assessment in Joslyn v Berryman (2003), where the court emphasised that the entire course of conduct leading to the accident must be considered when apportioning responsibility.

The Compulsory Third Party (CTP) insurer makes the initial assessment of the contributory negligence percentage during the fault investigation and states the percentage in the liability notice. The claimant can accept the CTP insurer's contributory negligence assessment or dispute it. If the parties cannot agree on the contributory negligence percentage, the court makes the final determination. The court's assessment of contributory negligence is binding on both parties.

Typical contributory negligence percentages in motor vehicle accident claims fall within recognisable ranges depending on the type of conduct involved.

• Minor lapse (momentary distraction): Contributory negligence reductions for a minor lapse typically range from 10% to 25%.
• Not wearing a seatbelt: Contributory negligence reductions for not wearing a seatbelt typically range from 10% to 25%.
• Speeding or failing to keep a proper lookout: Contributory negligence reductions for speeding or failing to keep a proper lookout typically range from 25% to 40%.
• Intoxication or serious recklessness: Contributory negligence reductions for intoxication or serious recklessness typically range from 40% to 60% or higher, subject to the statutory minimums prescribed by the Civil Liability Act 2003 (Qld).

The dollar impact of any contributory negligence percentage on a specific claim can be modelled by some personal injury compensation calculators, which apply the CN reduction to the assessed total of each head of damage to produce a net claim figure.

Who has to prove contributory negligence?

The defendant has to prove contributory negligence, not the claimant. In a motor vehicle accident compensation claim, the Compulsory Third Party (CTP) insurer of the at-fault vehicle bears the onus of proving contributory negligence on the balance of probabilities. The CTP insurer must prove that the claimant failed to take reasonable care for their own safety and that the failure contributed to the motor vehicle accident or the severity of the injuries.

The claimant does not need to disprove contributory negligence. The claimant does not need to prove they were driving carefully or that their actions were reasonable. The CTP insurer must affirmatively establish that the claimant's conduct fell below the standard expected of a reasonable person in the same circumstances for the contributory negligence defence to succeed.

Contributory negligence cannot be raised as a defence if the defendant's conduct was intentional or malicious. The contributory negligence defence is only available where the defendant's liability arises from ordinary negligence, not from deliberate wrongdoing.

Does contributory negligence apply to children?

Yes, contributory negligence applies to children, but children aged 5 and above are assessed against the standard of a reasonable child of the same age and life experience, not against an adult standard. Children under 5 cannot be found contributorily negligent at all. The lower standard of care for contributory negligence involving children recognises that children have less developed judgment, hazard awareness, and impulse control than adults.

The reasonable child standard for contributory negligence was established by the High Court of Australia in McHale v Watson (1966). The court held that the standard of care expected of a child must take into account the child's age, experience, and developmental stage. A 7-year-old who runs onto the road is not assessed against the same standard of contributory negligence as an adult pedestrian.

In motor vehicle accident claims involving children, contributory negligence is most commonly raised where the child was a pedestrian or cyclist who entered the road without looking. The CTP insurer must prove that the child's conduct fell below the standard expected of a reasonable child of the same age, which is a more difficult threshold to meet for contributory negligence than the adult standard. Younger children are rarely found contributorily negligent because the court recognises that children under a certain age cannot reasonably be expected to assess traffic risks. The same age-based assessment applies across all personal injury claims for children, with the contributory negligence standard adjusted for developmental capacity rather than calendar age.

How do you dispute a contributory negligence finding?

A contributory negligence finding is disputed by challenging the evidence the CTP insurer relied on, presenting additional evidence that the claimant acted reasonably, or arguing that the contributory negligence percentage attributed to the claimant is too high. The Compulsory Third Party (CTP) insurer's assessment of contributory negligence is not a final legal determination. It is the insurer's position on contributory negligence and it can be challenged at every stage of the claim.

There are 3 grounds on which a contributory negligence finding can be disputed.

• The claimant's actions did not contribute to the accident or the injuries: The claimant can argue that their conduct, while potentially a breach of the road rules, did not actually cause or contribute to the motor vehicle accident. A claimant who was slightly exceeding the speed limit but was hit by a driver who ran a red light may argue that the speeding played no role in the collision occurring and that no contributory negligence should apply.
• The claimant acted reasonably in the circumstances: The claimant can present evidence that their conduct was reasonable given the specific circumstances of the motor vehicle accident. A pedestrian who crossed mid-block on a quiet suburban street with clear visibility may argue that their actions were reasonable even though they were not at a designated crossing, and that the contributory negligence finding is not justified.
• The contributory negligence percentage is too high: The claimant can accept that some contributory negligence applies but dispute the percentage. A CTP insurer asserting 40% contributory negligence for not wearing a seatbelt may be challenged with evidence that the typical contributory negligence reduction for that conduct is 10% to 25% based on comparable cases.

A compulsory conference is required before court proceedings can commence. The format of a compulsory conference gives the claimant's personal injury lawyer an opportunity to present additional evidence and negotiate a revised contributory negligence percentage directly with the CTP insurer. Court proceedings are commenced if the parties cannot agree on the contributory negligence percentage, and the court makes a binding determination.

Does contributory negligence apply to claims other than motor vehicle accidents?

Yes, contributory negligence applies to all personal injury claim types in Queensland, not just motor vehicle accidents. The same legal principles of contributory negligence, the same standard of care, and the same statutory framework under the Law Reform Act 1995 (Qld) and the Civil Liability Act 2003 (Qld) govern contributory negligence across every claim type.

The most common examples of contributory negligence outside motor vehicle accidents include:

• Workplace injuries: A worker who fails to follow safety procedures, refuses to wear required protective equipment, or ignores safety warnings may be found contributorily negligent in a workers' compensation common law claim. The contributory negligence assessment considers whether the worker's conduct fell below the standard expected of a reasonable worker in the same role and circumstances.
• Public liability claims: A person who slips and falls in a shopping centre but was looking at their phone, wearing inappropriate footwear, or ignoring wet floor signage may be found contributorily negligent in a public liability claim. The contributory negligence assessment considers whether the claimant took reasonable care for their own safety in the environment.
• Medical negligence claims: A patient who fails to follow prescribed treatment, does not disclose relevant medical history, or misses scheduled follow-up appointments may have their compensation reduced through a contributory negligence finding in a medical negligence compensation claim if those failures contributed to the worsening of the condition.

The principles of contributory negligence are identical across all claim types. The defendant must prove on the balance of probabilities that the claimant's conduct fell below the standard of a reasonable person and that the conduct contributed to the harm. The court reduces the compensation by a contributory negligence percentage that reflects the claimant's share of responsibility.
