Your Compulsory Third Party (CTP) insurance is paid at the same time as your motor vehicle registration. Just as registration of your vehicle is compulsory, so is CTP insurance.

Your CTP insurance premium provides cover under a compulsory Policy of Insurance under the Motor Vehicles Act 1959. The minimum terms and conditions of the CTP insurance policy are set by the CTP Regulator.

What is covered?

The Policy of Insurance protects you (and other people who use your registered and insured vehicle, with or without your consent) against the financial impact of causing injury or death to other road users through the use of your vehicle anywhere in Australia.

You are not able to make a claim if you were the driver entirely at fault for the accident. However, most accidents involve some sharing of fault between drivers. If you are unsure, you can lodge a claim with the insurer of the other driver you believe contributed to the accident.

If an unknown or unregistered (and therefore uninsured for CTP) vehicle is involved, the Regulator will provide cover under the Nominal Defendant Scheme and allocate management of your claim to one of the CTP Insurers.

Different coverage for a child's claim

The CTP Scheme provides at fault cover for a child under 16 years of age for an accident that occurs in South Australia (for example when the child is an underage driver) for their necessary and reasonable treatment, care and support. This cover also applies when the vehicle is registered interstate.

What is not covered?

CTP insurance does not cover:

  • damage to property (including to a vehicle or its contents)
  • an at-fault cyclist who injures themselves or another road user
  • causing injury or death to another participant in a road race
  • the driver of a single car accident, for example if you hit a tree (with the exception of very serious, lifelong injuries which may be covered under the Lifetime Support Scheme).

Lifetime Support Scheme

If you sustain very serious, lifelong injuries in a motor vehicle accident in South Australia, you may be eligible for necessary and reasonable treatment, care and support under the Lifetime Support Scheme (LSS), regardless of fault.

Depending on your circumstances, you may be eligible to lodge a CTP claim for compensation if you were not at fault for the accident as well as a claim under the LSS.
