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 
An excess payment, also known as a deductible, is a fixed contribution that must be paid each time a car is repaired with the charges billed to an automotive insurance policy. Normally this payment is made directly to the accident repair "garage" (the term "garage" refers to an establishment where vehicles are serviced and repaired) when the owner collects the car. If one's car is declared to be a "write off" (or "totaled"), then the insurance company will deduct the excess agreed on the policy from the settlement payment it makes to the owner.
To reduce the insurance premium, the insured party may offer to pay a higher excess (deductible) than the compulsory excess demanded by the insurance company. The voluntary excess is the extra amount, over and above the compulsory excess, that is agreed to be paid in the event of a claim on the policy. As a bigger excess reduces the financial risk carried by the insurer, the insurer is able to offer a significantly lower premium.
More commonly purchased is third party, fire and theft. This covers all third party liabilities and also covers the vehicle owner against the destruction of the vehicle by fire (whether malicious or due to a vehicle fault) and theft of the insured vehicle. It may or may not cover vandalism. This kind of insurance and the two preceding types do not cover damage to the vehicle caused by the driver or other hazards.
The registration number of the vehicle shown on the insurance policy, along with other relevant information including the effective dates of cover are transmitted electronically to the UK's Motor Insurance Database (MID) which exists to help reduce incidents of uninsured driving in the territory. The Police are able to spot-check vehicles that pass within range of automated number plate recognition (ANPR) cameras, that can search the MID instantly. It should be noted, however, that proof of insurance lies entirely with the issue of a Certificate of Motor Insurance, or cover note, by an Authorised Insurer which, to be valid, must have been previously 'delivered' to the insured person in accordance with the Act, and be printed in black ink on white paper.
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.
