The immediate impounding of an apparently uninsured vehicle replaces the former method of dealing with insurance spot-checks where drivers were issued with an HORT/1 (so-called because the order was form number 1 issued by the Home Office Road Traffic dept). This 'ticket' was an order requiring that within seven days, from midnight of the date of issue, the driver concerned was to take a valid insurance certificate (and usually other driving documents as well) to a police station of the driver's choice. Failure to produce an insurance certificate was, and still is, an offence. The HORT/1 was commonly known – even by the issuing authorities when dealing with the public – as a "Producer". As these are seldom issued now and the MID relied upon to indicate the presence of insurance or not, it is incumbent upon the insurance industry to accurately and swiftly update the MID with current policy details and insurers that fail to do so can be penalised by their regulating body.
Most existing no-fault plans are limited in the sense that they usually permit the insured party to sue the party at fault for damages in excess of those covered by the plan and permit insuring companies to recover costs from each other according to decisions on liability. Total no-fault insurance, on the other hand, would not permit the insured to enter tort liability actions or the insurer to recover costs from another insurer.
When the premium is not mandated by the government, it is usually derived from the calculations of an actuary, based on statistical data. The premium can vary depending on many factors that are believed to affect the expected cost of future claims. Those factors can include the car characteristics, the coverage selected (deductible, limit, covered perils), the profile of the driver (age, gender, driving history) and the usage of the car (commute to work or not, predicted annual distance driven).
CTP insurance is compulsory in every state in Australia and is paid as part of vehicle registration. It covers the vehicle owner and any person who drives the vehicle against claims for liability for death or injury to people caused by the fault of the vehicle owner or driver. CTP may include any kind of physical harm, bodily injuries and may cover the cost of all reasonable medical treatment for injuries received in the accident, loss of wages, cost of care services and, in some cases, compensation for pain and suffering. Each state in Australia has a different scheme.
