How insurers assess liability in motorcycle lane filtering incidents
A threshold injury under the Motor Accident Injuries Act 2017 (NSW) includes a soft tissue injury and a psychological or psychiatric injury that is not a recognised psychiatric illness (adjustment disorder and acute stress disorder are the usual examples; s 1.6 and Motor Accident Guidelines Part 5).
In New South Wales, insurers assess liability in motorcycle lane filtering incidents by applying the Motor Accident Injuries Act 2017 (MAIA) and the Motor Accident Injuries Regulation 2017. Liability is determined based on the circumstances of the accident, not the mode of travel. Insurers examine whether the motorcyclist’s actions were reasonable and safe under the prevailing conditions, including traffic speed, visibility, and road layout. In Greater Sydney, where traffic congestion is common, lane filtering is often undertaken in slow-moving or stopped traffic. Insurers assess whether the motorcyclist maintained a safe speed, kept a reasonable distance from other vehicles, and used appropriate caution when changing lanes. The presence of a clear lane or designated motorcycle lane may also be considered.
Legal framework for lane filtering in NSW
Lane filtering is not explicitly prohibited under the Road Transport Act 2013 or the Road Rules 2014. However, the practice must comply with the general duty to drive safely under the Road Transport Act 2013, which requires drivers to act with reasonable consideration for the safety of others. The Motor Accident Injuries Act 2017 governs all CTP claims in NSW, including those involving motorcyclists who filter between lanes. Under this law, a claim may still be made regardless of fault, but entitlement to damages depends on whether the injury meets the threshold for a claim. Insurers assess whether the motorcyclist’s actions contributed to the accident, and if so, whether that contribution affects the claim’s outcome.
Factors insurers consider in liability assessment
Insurers assess liability by reviewing several key factors. These include:
- The speed and behaviour of the motorcyclist during filtering
- Whether the filtering occurred in a designated or safe area
- The presence of traffic signals, road markings, or signage
- Whether the motorcyclist had a clear view of surrounding vehicles
- The actions of other drivers involved, including whether they changed lanes unexpectedly
Insurers may review video footage from dash cameras, traffic cameras, or mobile phones. Witness statements, police reports, and medical records are also examined. In Greater Sydney, where road networks are complex and traffic density varies, insurers often rely on technical assessments to reconstruct the sequence of events. The motorcyclist’s compliance with road rules, including the use of lights and signals, is also evaluated.
What happens if the motorcyclist is found to be at fault
If a motorcyclist is found to have contributed to the accident, their claim may still proceed under the CTP scheme. Under the MAIA, a claimant may still receive treatment and care benefits and weekly income payments, even if they are partially at fault. However, if the injury is a threshold injury, the right to claim damages is limited. The motorcyclist must still meet the threshold for a claim, which includes a permanent impairment of at least 10% of the whole person, or a permanent loss of a body function. If the injury does not meet this threshold, the claimant may only receive benefits for treatment and care and up to 52 weeks of weekly payments, regardless of fault.
Practical steps and evidence to preserve
If you were involved in a lane filtering incident in Greater Sydney, you should:
- Seek medical attention immediately, even if injuries seem minor
- Report the incident to the police if there was damage, injury, or dispute
- Collect and preserve evidence such as photos of the scene, video from a dash cam or mobile phone, and contact details of witnesses
- Keep a record of all medical treatment, including dates, diagnoses, and prescribed care
- Notify your insurer as soon as possible, even if you are unsure whether you are at fault
These steps help ensure that your claim is not compromised by a lack of evidence. Insurers may reject a claim if critical evidence is not provided within a reasonable time.
Time limits and dispute options
There is a time limit to make a CTP claim in NSW. You must notify your insurer within 3 months of the accident, or within 12 months of when you first became aware of the injury. If you miss this deadline, you may still be able to apply to the Civil and Administrative Tribunal (NCAT) for an extension, but this is not guaranteed. If your claim is rejected or you disagree with the insurer’s assessment of liability, you may request a review or apply to NCAT for a determination. The SIRA provides guidance on how to make a claim and what to expect during the process.
Hypothetical example
A motorcyclist in Sydney’s inner west was filtering between slow-moving vehicles during peak hour when a car suddenly changed lanes without signalling. The motorcyclist collided with the car’s side mirror, resulting in a neck injury. The insurer reviewed dash cam footage, confirmed the motorcyclist was travelling at a moderate speed and had a clear view of the surrounding traffic. The car driver was found to have failed to check their blind spot. The insurer accepted liability and approved treatment and care benefits. The motorcyclist later met the threshold for a claim and was awarded damages for pain and suffering.
