Immediate actions after a T-bone collision

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).

After a T-bone side impact collision in Greater Sydney, the most important steps are to seek medical attention, report the incident, and preserve evidence. Injuries from side impacts can be severe even if the vehicle appears undamaged. You must contact a medical practitioner as soon as possible to document your condition and begin treatment. This is critical for establishing a link between the accident and any injury, which is required under the Motor Accident Injuries Act 2017.

You must also report the accident to the insurer of the vehicle that caused the collision. If you are not sure which insurer to contact, you can use the SIRA claims portal to identify the correct CTP insurer. You should notify the insurer within 28 days of the accident to avoid delays in processing your claim. Failure to report within this timeframe may affect your eligibility for benefits, although exceptions may apply if there was a reasonable excuse.

How SIRA handles T-bone collision claims in NSW

The State Insurance Regulatory Authority (SIRA) oversees all Compulsory Third Party (CTP) claims in New South Wales, including those arising from T-bone collisions at intersections and driveways. SIRA ensures that claims are processed under the Motor Accident Injuries Act 2017, which sets out the framework for compensation.

If you were injured as a driver, passenger, pedestrian, cyclist, or motorcyclist, you may be entitled to statutory benefits under the CTP scheme. These include treatment and care benefits, weekly income payments, and, in some cases, damages. The type of benefit available depends on the nature and severity of your injuries, whether you have a threshold injury, and whether you have a whole person impairment.

SIRA does not determine fault for the purpose of benefits. Under the CTP scheme, you can receive benefits regardless of who was at fault, as long as you were injured in a motor vehicle accident that occurred in NSW. However, fault may still be relevant if you later seek damages through a common law claim.

What to do with evidence and records

Preserving evidence is essential to support your CTP claim. Collect and keep the following items:

  • Medical records from every visit, including diagnosis, treatment plan, and any assessment of impairment
  • Photographs of the accident scene, vehicle damage, and any visible injuries
  • A copy of the police report, if one was prepared
  • Contact details for any witnesses
  • A record of all out-of-pocket expenses related to the injury, such as transport to appointments or medical supplies
  • Correspondence with the insurer, including emails and letters

These documents help establish the cause of your injury, the extent of your harm, and the impact on your daily life. SIRA advises that the more complete your record, the stronger your claim will be.

Time limits and claim deadlines

There are time limits that apply to reporting and making a claim after a T-bone collision. You must notify the insurer of the vehicle that caused the accident within 28 days of the incident. This deadline is strict and must be met unless there was a reasonable excuse.

If you are claiming damages, you must start legal proceedings within three years of the accident date. This is a statutory deadline under the Limitation Act 1969. Missing this deadline means you may lose your right to claim damages, even if you have a valid injury and a strong case.

For statutory benefits, such as weekly income payments or treatment and care benefits, there is no time limit to apply. However, if you have a threshold injury (such as a soft-tissue injury that meets the definition in the Motor Accident Guidelines), and your only injuries are threshold injuries, your weekly benefits and treatment and care benefits are generally limited to 52 weeks under the Motor Accident Injuries Act 2017.

When to seek independent advice

If you are unsure about your rights, the type of benefits you may be entitled to, or whether you should pursue a damages claim, it is advisable to seek independent legal advice. This is particularly important if:

  • Your injuries are complex or ongoing
  • You have a whole person impairment of 10% or more
  • You believe the insurer has denied or delayed your claim
  • You are considering a common law damages claim

A solicitor can help you understand whether you meet the threshold injury criteria, assess the value of your claim, and assist with the formal process of making a claim through SIRA.

Hypothetical example

A cyclist in Sydney was struck by a car in a T-bone collision at a busy intersection. The cyclist sustained a whiplash injury and a minor fracture to the wrist. They sought medical treatment within 24 hours and kept all medical records. They reported the accident to the insurer within 10 days and collected photos of the scene and vehicle damage. After 12 weeks, the cyclist was still unable to return to work and applied for weekly income payments. Their claim was approved under the CTP scheme because they had a threshold injury and were not at fault.
