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. [6]
As a practical matter, resetting odometers requires equipment plus expertise that makes stealing insurance risky and uneconomical. For example, to steal 20,000 miles [32,200 km] of continuous protection while paying for only the 2000 in the 35000 to 37000 range on the odometer, the resetting would have to be done at least nine times, to keep the odometer reading within the narrow 2,000-mile [3,200 km] covered range. There are also powerful legal deterrents to this way of stealing insurance protection. Odometers have always served as the measuring device for resale value, rental and leasing charges, warranty limits, mechanical breakdown insurance, and cents-per-mile tax deductions or reimbursements for business or government travel. Odometer tampering, detected during claim processing, voids the insurance and, under decades-old state and federal law, is punishable by heavy fines and jail.
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.
Multi car insurance is designed for households with more than one car, and you can usually cover up to a maximum of five cars on one policy. You can think of it as a family car insurance policy, where each additional vehicle on the policy earns a further multi car discount from the insurer. While some insurers will only cover cars registered to the same address, the best multi car insurance policies will also allow you to cover cars driven by your immediate family, even if they live elsewhere.
Metromile also uses an OBDII-based system for their mileage-based insurance. They offer a true pay-per-mile insurance where behavior or driving style is not taken into account, and the user only pays a base rate along with a fixed rate per mile.[53] The OBD-II device measures mileage and then transmits mileage data to servers. This is supposed to be an affordable car insurance policy for low-mileage drivers. Metromile is currently only offering personal car insurance policies and is available in California, Oregon, Washington, and Illinois.[54]
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.
The Progressive Corporation launched Snapshot to give drivers a customized insurance rate based on recording how, how much, and when their car is driven.[52] Snapshot is currently available in 46 states plus the District of Columbia. Because insurance is regulated at the state level, Snapshot is currently not available in Alaska, California, Hawaii, and North Carolina.[52] Driving data is transmitted to the company using an on-board telematic device. The device connects to a car's OnBoard Diagnostic (OBD-II) port (all petrol automobiles in the USA built after 1996 have an OBD-II.) and transmits speed, time of day and number of miles the car is driven. Cars that are driven less often, in less-risky ways, and at less-risky times of day, can receive large discounts. Progressive has received patents on its methods and systems of implementing usage-based insurance and has licensed these methods and systems to other companies.
For example, a 50-year-old woman with 30 years' driving experience and a squeaky clean licence is in a prime position for one of the cheapest insurance policies available. Her 18-year-old daughter on the other hand, recently unleashed onto the roads, will be considered a far higher risk for the insurer, consequently increasing the overall cost.

The use of non-intrusive load monitoring to detect drunk driving and other risky behaviors has been proposed.[57] A US patent application combining this technology with a usage based insurance product to create a new type of behavior based auto insurance product is currently open for public comment on peer to patent.[58] See Behavior-based safety. Behaviour based Insurance focusing upon driving is often called Telematics or Telematics2.0 in some cases monitoring focus upon behavioural analysis such as smooth driving.

We aim to show you car insurance quotes from as many insurance companies as possible, so that you can find the right policy for you. Unfortunately, we can’t promise to show quotes from every insurance provider, because not all companies want to be included on comparison websites. We won’t offer you advice or make a recommendation, but we will provide you with all the information you need to help you decide which is the right policy for you. You can find out more about how we work here.
[1] Availability varies. Enrollment discount applies during data collection; final discount is calculated on driving behavior and could be zero. Discounts do not apply to all coverage elements; actual savings vary by state, coverage selections, rating factors and policy changes. Final discount applies at the next policy renewal and remains until drivers or vehicles on the policy change.

Insurance companies have started using credit ratings of their policyholders to determine risk. Drivers with good credit scores get lower insurance premiums, as it is believed that they are more financially stable, more responsible and have the financial means to better maintain their vehicles. Those with lower credit scores can have their premiums raised or insurance canceled outright.[55] It has been shown that good drivers with spotty credit records could be charged higher premiums than bad drivers with good credit records.[56]

Under the cents-per-mile system, rewards for driving less are delivered automatically, without the need for administratively cumbersome and costly GPS technology. Uniform per-mile exposure measurement for the first time provides the basis for statistically valid rate classes. Insurer premium income automatically keeps pace with increases or decreases in driving activity, cutting back on resulting insurer demand for rate increases and preventing today's windfalls to insurers, when decreased driving activity lowers costs but not premiums.
It’s important to note that every company considers credit very differently, and even among insurers this factor fluctuates by state. For example, NerdWallet’s 2019 car insurance rate analysis indicates that while State Farm charges higher rates for poor credit in many states, it doesn’t seem to do so in Maine. Similar variations are true for many other companies as well.
