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. The scheme allocates one provider for 3 years as part of vehicle registration. After July 2019, vehicle owners can choose a different CTP insurer and new insurers may also enter the market. 
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.
In Norway, the vehicle owner must provide the minimum of liability insurance for his/her vehicle(s) – of any kind. Otherwise, the vehicle is illegal to use. If a person drives a vehicle belonging to someone else, and has an accident, the insurance will cover for damage done. Note that the policy carrier can choose to limit the coverage to only apply for family members or person over a certain age.
Liability insurance pays for damage to someone else’s property or for injury to other persons resulting from an accident for which the insured is judged legally liable; collision insurance pays for damage to the insured car if it collides with another vehicle or object; comprehensive insurance pays for damage to the insured car resulting from fire or theft or many other causes; medical-payment insurance covers medical treatment for the policyholder and his passengers.
You might have a roommate or family member on your policy that no longer drives your vehicles. Or maybe you have a vehicle on your policy that is no longer being driven. Making sure driver and vehicle information is up to date may save you money. Keep in mind, if you do go down to just one car on your policy, you will lose the multi-vehicle discount.
Several Canadian provinces (British Columbia, Saskatchewan, Manitoba and Quebec) provide a public auto insurance system while in the rest of the country insurance is provided privately [third party insurance is privatized in Quebec and is mandatory. The province covers everything but the vehicle(s)]. Basic auto insurance is mandatory throughout Canada with each province's government determining which benefits are included as minimum required auto insurance coverage and which benefits are options available for those seeking additional coverage. Accident benefits coverage is mandatory everywhere except for Newfoundland and Labrador. All provinces in Canada have some form of no-fault insurance available to accident victims. The difference from province to province is the extent to which tort or no-fault is emphasized. International drivers entering Canada are permitted to drive any vehicle their licence allows for the 3-month period for which they are allowed to use their international licence. International laws provide visitors to the country with an International Insurance Bond (IIB) until this 3-month period is over in which the international driver must provide themselves with Canadian Insurance. The IIB is reinstated every time the international driver enters the country. Damage to the driver's own vehicle is optional – one notable exception to this is in Saskatchewan, where SGI provides collision coverage (less than a $1000 deductible, such as a collision damage waiver) as part of its basic insurance policy. In Saskatchewan, residents have the option to have their auto insurance through a tort system but less than 0.5% of the population have taken this option.
In 1998, the Progressive Insurance company started a pilot program in Texas, in which drivers received a discount for installing a GPS-based device that tracked their driving behavior and reported the results via cellular phone to the company. The program was discontinued in 2000. In following years many policies (including Progressive) have been trialed and successfully introduced worldwide into what are referred to as Telematic Insurance. Such 'telematic' policies typically are based on black-box insurance technology, such devices derive from a stolen vehicle and fleet tracking but are used for insurance purposes. Since 2010 GPS-based and Telematic Insurance systems have become more mainstream in the auto insurance market not just aimed at specialised auto-fleet markets or high value vehicles (with an emphasis on stolen vehicle recovery). Modern GPS-based systems are branded as 'PAYD' Pay As You Drive insurance policies, 'PHYD' Pay How You Drive or since 2012 Smartphone auto insurance policies which utilise smartphones as a GPS sensor, e.g. . A detailed survey of the smartphone as measurement probe for insurance telematics is provided in 
The cheapest car insurance, period, will likely carry the minimum coverage required in your state. In most states, this is liability insurance only, which covers property damage and medical bills for others due to accidents you cause. Some states also require uninsured and underinsured motorist coverage, which pay for your injuries or damage if an at-fault driver doesn’t have enough insurance.
There are three states that do not have a private CTP scheme. In Victoria, the Transport Accident Commission provides CTP through a levy in the vehicle registration fee, known as the TAC charge. A similar scheme exists in Tasmania through the Motor Accidents Insurance Board. A similar scheme applies in Western Australia, through the Insurance Commission of Western Australia (ICWA).
