Vehicle Classifications

An important factor in CTP greenslip prices

Vehicle class is one of the important factors used by insurers for setting CTP greenslip prices.

Insurers are required to set CTP green slip prices on the basis of guidelines issued by State Insurance Regulatory Authority (SIRA). Part 1 of Motor Accident Guidelines is Premiums Determination (PD) and this is updated each year. The PD is based on vehicle classes and rating regions (geographic zones) that insurers must apply. Classifications are the same for all insurers.

The table below shows a simplified version of the main vehicle classes from Schedule of Premium Relativities.

  • Passenger vehicles are generally Class 1. There is no differentiation within Class 1 on the basis of performance or engine capacity. A small four cylinder sedan is treated in the same way as a high performance sports car and a passenger carrying four wheel drive.
  • Motorbikes are Class 10. There are five subclassifications within Class 10, differentiating motorbikes on the basis of engine capacity. Other than engine capacity, there is no further differentiation within Class 10, ignoring motorbike style, use and pillion capacity.
