T-bone side impacts, common mistakes to avoid

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).

T-bone collisions at intersections or driveways often result in significant injuries. In regional NSW, claimants must navigate the Compulsory Third Party (CTP) scheme under the Motor Accident Injuries Act 2017. This article explains common errors to avoid when pursuing CTP claims after side-impact collisions.

Key CTP rules for T-bone collisions

SIRA applies the CTP scheme uniformly across NSW, including regional areas. Key principles include:

  • Statutory benefits cover treatment, income loss, and care costs for injuries meeting the 'threshold injury' definition in the Motor Accident Guidelines.
  • Fault does not affect CTP claims, the at-fault driver’s insurer pays regardless of who is at fault.
  • Time limits apply: claims must be submitted within 3 years of the accident date (s 4.4 of the Motor Accident Injuries Act 2017).

Practical steps and evidence to avoid errors

Claimants in regional NSW should take these steps to avoid mistakes:

  • Document the accident scene, take photos of vehicle damage, road conditions, and any visible injuries. A lack of evidence can delay claims.
  • Seek immediate medical attention, injuries from T-bone collisions may not show symptoms immediately. Delayed treatment can affect eligibility for statutory benefits.
  • Report the claim to SIRA, failure to notify the insurer within 3 years may result in a claim being rejected.
  • Keep records of income and expenses, weekly income payments depend on proof of lost wages, while treatment benefits require medical records.

Time limits, disputes and when to seek advice

CTP claims must be submitted within 3 years of the accident. Regional claimants should note that processing times may vary due to limited access to SIRA offices or legal services. If disputes arise over injury severity or benefits, claimants should:

  • Review SIRA’s guidelines, the Motor Accident Guidelines define 'threshold injuries' and outline how benefits are calculated.
  • Seek independent medical assessment, disputes over injury severity may require a second opinion from a registered medical practitioner.
  • Contact SIRA directly, claimants can request a review of their case through the insurer’s internal process.

A common mistake is assuming all injuries qualify for benefits. For example, a claimant who suffered a soft-tissue injury without neurological signs may not meet the threshold injury definition under the Motor Accident Guidelines. This can lead to denied claims for treatment and income support.

When to seek legal advice

While SIRA provides resources for self-claiming, regional claimants may benefit from legal assistance to:

  • Navigate complex evidence requirements.
  • Challenge disputes over injury severity.
  • Ensure compliance with time limits.

Every claim depends on its own facts. To request contact about your circumstances, complete the quick, no obligation enquiry form.
