In 1930, the UK Government introduced a law that required every person who used a vehicle on the road to have at least third-party personal injury insurance. Today, this law is defined by the Road Traffic Act 1988, (generally referred to as the RTA 1988 as amended) which was last modified in 1991. The Act requires that motorists either be insured, or have made a specified deposit (£500,000 in 1991) and keeps the sum deposited with the Accountant General of the Supreme Court, against liability for injuries to others (including passengers) and for damage to other persons' property, resulting from use of a vehicle on a public road or in other public places.
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 
While most of us are eager in availing no-claim bonuses (a discount in premium at renewal if no claim is made during the policy term), but we hardly pay attention towards other smaller discounts which can add up to a substantial amount. All comprehensive insurance plans offer reward for good claim history, with a discount which could be 50% of the premium.
Cash in on major life changes. Certain life events could translate to cheaper car insurance, so shop for quotes whenever something major changes in your life. For instance, many companies offer a lower rate for married couples or domestic partners. Or perhaps you moved to a suburb with lower accident and crime rates. If your risk for accidents goes down, your rates just might, too.
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.
Senior drivers are often eligible for retirement discounts, reflecting the lower average miles driven by this age group. However, rates may increase for senior drivers after age 65, due to increased risk associated with much older drivers. Typically, the increased risk for drivers over 65 years of age is associated with slower reflexes, reaction times, and being more injury-prone.
