Another important factor in determining car-insurance premiums involves the annual mileage put on the vehicle, and for what reason. Driving to and from work every day at a specified distance, especially in urban areas where common traffic routes are known, presents different risks than how a retiree who does not work any longer may use their vehicle. Common practice has been that this information was provided solely by the insured person, but some insurance providers have started to collect regular odometer readings to verify the risk.
Two of the most important factors that go into determining the underwriting risk on motorized vehicles are: performance capability and retail cost. The most commonly available providers of auto insurance have underwriting restrictions against vehicles that are either designed to be capable of higher speeds and performance levels, or vehicles that retail above a certain dollar amount. Vehicles that are commonly considered luxury automobiles usually carry more expensive physical damage premiums because they are more expensive to replace. Vehicles that can be classified as high performance autos will carry higher premiums generally because there is greater opportunity for risky driving behavior. Motorcycle insurance may carry lower property-damage premiums because the risk of damage to other vehicles is minimal, yet have higher liability or personal-injury premiums, because motorcycle riders face different physical risks while on the road. Risk classification on automobiles also takes into account the statistical analysis of reported theft, accidents, and mechanical malfunction on every given year, make, and model of auto.
There are many factors such as IDV, deductibles, seating capacity, cubic capacity, previous insurance history etc. that affect the insurance premium that you would pay. For comprehensive insurance plans, premium charges vary insurance provider per insurance provider on the basis of the coverage provided. Compare insurance premiums so that you get the best quote.
In South Australia, since July 2016, CTP is no longer provided by the Motor Accident Commission.The government has now licensed four private insurers - AAMI, Allianz, QBE and SGIC, to offer CTP insurance SA.

Motor insurers in the UK place a limit on the amount that they are liable for in the event of a claim by third parties against a legitimate policy. This can be explained in part by the Great Heck Rail Crash that cost the insurers over £22,000,000 in compensation for the fatalities and damage to property caused by the actions of the insured driver of a motor vehicle that caused the disaster. No limit applies to claims from third parties for death or personal injury, however UK car insurance is now commonly limited to £20,000,000 for any claim or series of claims for loss of or damage to third party property caused by or arising out of one incident.
