If the younger driver is covering his own costs, it might be cheaper for him to take out his own policy but include one of the older, lower risk drivers from the household as a named driver (as long as the older drive will use the car). However, if the older driver is footing the bill for both policies, multi-car insurance may still work out cheaper.
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.
Cents Per Mile Now (1986) advocates classified odometer-mile rates, a type of usage-based insurance. After the company's risk factors have been applied, and the customer has accepted the per-mile rate offered, then customers buy prepaid miles of insurance protection as needed, like buying gallons of gasoline (litres of petrol). Insurance automatically ends when the odometer limit (recorded on the car's insurance ID card) is reached, unless more distance is bought. Customers keep track of miles on their own odometer to know when to buy more. The company does no after-the-fact billing of the customer, and the customer doesn't have to estimate a "future annual mileage" figure for the company to obtain a discount. In the event of a traffic stop, an officer could easily verify that the insurance is current, by comparing the figure on the insurance card to that on the odometer.
The 12-month policy will generally start on the date that the last car insurance is up for renewal, with short-term cover used to protect the other cars in the interim. For example, if you have one car that needs to be insured from February and another in June, the February car will be insured first but the policy will actually renew in June when both cars are covered. After the last car has been insured for a full 12 months, the policy will renew each year until you choose another policy.
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 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 
For instance, if your automobile is registered in Chennai, the applicable charges for Zone A would be charged. Even if you shift to another town or city, the same charges would be applied. Likewise, if an automobile is registered in a town, Zone B premium charges are applicable. Later on, in case the vehicle own moves to a metro city, he would be charged the rate of the Zone B only
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).
A lot goes into an auto insurance rate quote, including your ZIP code, coverage levels, marital status, annual mileage, driving history and vehicle make, year and model. In most states, your gender and credit history are also used to determine rates. And again, the reason auto insurance comparison shopping is so important is because rates between companies are different for each person, too.
