Understanding Contributory Negligence in NSW Motor Accident Claims

Contributory negligence in New South Wales refers to a situation where the injured person’s own actions contributed to the motor accident. Under the Motor Accident Injuries Act 2017, this can reduce the amount of compensation they receive, even if the other driver was at fault. The law does not require a claim to be abandoned if the injured person was partly at fault, instead, the compensation is adjusted proportionally. This applies to drivers, passengers, pedestrians, cyclists and motorcyclists involved in motor accidents across Greater Sydney.

How Contributory Negligence Affects Your Claim

If a court or insurer finds that you contributed to the accident, your entitlement to compensation may be reduced. For example, if you were not wearing a seatbelt, were distracted by a mobile phone, or failed to stop at a red light, these actions may be considered in assessing your share of responsibility. The reduction is not automatic, it depends on the evidence and the degree of fault assigned. The Motor Accident Injuries Act 2017 allows for a proportionate reduction in damages, meaning you may still receive compensation, but less than the full amount.

Evidence and Records to Keep After a Motor Accident in Greater Sydney

To support your claim and to defend against a potential contributory negligence finding, it is essential to preserve and collect the following evidence immediately after the accident:

  • A detailed record of the accident scene, including photographs of vehicle damage, road conditions, traffic signs, and weather conditions. Use your mobile phone to capture images from multiple angles.
  • A written account of the events, including the time, location, weather, and sequence of actions leading up to the collision. Write this as soon as possible while details are fresh.
  • Contact details and statements from any witnesses present at the scene. Ask them to write down what they saw and provide their contact information.
  • Official accident report, if a police officer attended the scene. Request a copy from the NSW Police Force.
  • Medical records from the time of the accident onwards, including emergency department notes, follow-up appointments, and any diagnostic imaging such as X-rays or MRIs.
  • Records of lost income, including payslips, employer letters, and any correspondence about work absence.
  • All correspondence with your insurer, including emails, letters, and call logs. Keep a record of who you spoke to and when.

Time Limits and Procedural Steps

Under the Motor Accident Injuries Act 2017, you must notify your insurer of a claim within 6 months of the accident. Failure to do so may result in a loss of rights to claim benefits. You must also provide medical evidence to support your injury claim within 12 months of the accident. These time limits apply across Greater Sydney and are strictly enforced.

If your insurer disputes your claim or questions your level of fault, you may request a review under the Motor Accident Injuries Regulation 2017. You can also apply to the NSW Civil and Administrative Tribunal (NCAT) for a determination on liability or compensation if an agreement cannot be reached.

When to Seek Legal Advice

A claim involving contributory negligence can become complex, particularly if there is a dispute over the degree of fault. The outcome depends on the strength of the evidence, the nature of the injury, and the specific circumstances of the accident. For instance, if you were crossing the road at a designated crossing but were hit by a driver who was speeding, the court may find that your fault was minor, resulting in a small reduction in compensation.

A hypothetical example: A pedestrian in Sydney CBD was struck by a car while crossing at a pedestrian light. The driver was speeding and failed to stop. The pedestrian was looking both ways before crossing and had no visible fault. However, the driver’s insurer argues that the pedestrian stepped into the road without checking again. The court would assess the evidence, such as traffic camera footage, witness statements, and the pedestrian’s medical records, to determine whether the pedestrian’s actions contributed to the accident and to what extent.
