Vehicle insurance

Vehicle insurance (or Auto insurance, car insurance, motor insurance) is insurance consumers can purchase for cars, trucks, and other vehicles. Its primary use is to provide protection against losses incurred as a result of traffic accidents. An insurance company may declare a vehicle totally destroyed ('totaled' or 'a write-off') if it appears replacement would be cheaper than repair.

Coverage levels

Insurance can cover some or all of the following items:

1. The insured party
2. The insured vehicle
3. Third parties

Different policies specify the circumstances under which each item is covered. For example, a vehicle can be insured against theft, fire damage, or accident damage independently.

Public policy

In many countries it is compulsory to purchase auto insurance before driving on public roads. In the United States, penalties for not purchasing auto insurance vary by state, but often involve a substantial fine, license and/or registration suspension or revocation, as well as possible jail time in some states. Usually the minimum required by law is third party insurance to protect third parties against the financial consequences of loss, damage or injury caused by a vehicle. Typically, coverage against loss of or damage to the driver's own vehicle is optional - one notable exception to this is in Saskatchewan, where SGI provides collision coverage (less a $700 deductible) as part of its basic insurance policy. In South Australia Third Party Personal insurance from the State Government Insurance Corporation (SGIC) is included in the license registration fee. South Africa allocates a percentage of the money from petrol into the Road Accidents Fund, which goes towards compensating third parties in accidents. Most countries relate insurance to both the car and the driver, however the degree of each varies greatly.

Basis of premium charges

Depending on the jurisdiction, the insurance premium can be either mandated by the government or determined by the insurance company in accordance to a framework of regulations set by the government. Often, the insurer will have more freedom to set the price on physical damage coverages than on mandatory liability coverages.

When the premium is not mandated by the government, it is usually derived from the calculations of an actuary based on statistical data. The premium can vary depending on many factors that are believed to have an impact on the expected cost of future claims. Those factors can include the car characteristics, the coverage selected (deductible, limit, covered perils), the profile of the driver (age, gender, driving history) and the usage of the car (commute to work or not, predicted annual distance driven).

Gender

Several insurance companies offer a lower premium to female drivers as statistically they are involved in fewer accidents. UK statistics show that men consistently committed more than 85% of serious motoring offences, including 97% of dangerous driving offences. This is one of many factors affecting premiums. However, an EC proposal would make it illegal to consider gender in assessing insurance premiums.

Age

Teen drivers who have no driving record will have higher car insurance premiums. However young drivers are often offered discounts if they undertake further driver training on recognised courses, such as the Pass Plus scheme in the U.K. In the U.S. many insurers offer a good grade discount to students with a good academic record and resident student discounts to those who live away from home. Generally insurance premiums tend to become lower at the age of 25. Senior drivers are often eligible for retirement discounts.

Distance

Some car insurance plans do not differentiate in regard to how much the car is used. However, methods of differentiation would include:

Reasonable estimation

Several car insurance plans rely on a reasonable estimation of the average annual distance expected to be driven which is provided by the insured. This discount benefits drivers who drive their cars infrequently but has no actuarial value since it is unverified.

Odometer-based systems

Cents Per Mile Now(1986) advocates classified odometer-mile rates. After the company's risk factors have been applied and the customer has accepted the per-mile rate offered, customers buy prepaid miles of insurance protection as needed, like buying gallons of gasoline. Insurance automatically ends when the odometer limit (recorded on the car’s insurance ID card) is reached unless more miles are 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.

Critics point out the possibility of cheating the system by odometer tampering. Although the newer electronic odometers are difficult to roll back, they can still be defeated by disconnecting the odometer wires and reconnecting them later. However, as the Cents Per Mile Now website points out: "As a practical matter, resetting odometers requires equipment plus expertise that makes stealing insurance risky and uneconomical. For example, in order to steal 20,000 miles of continuous protection while paying for only the 2,000 miles from 35,000 miles to 37,000 miles 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 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."

Under the cents-per-mile system, rewards for driving less are delivered automatically without need for administratively cumbersome and costly 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.

GPS-based system

In 1998, Progressive Insurance started a pilot program in Texas in which volunteers installed a GPS-based technology called Autograph in exchange for a discount. The device tracked their driving behavior and reported the results via cellular phone to the company. Policyholders were reportedly more upset about having to pay for the expensive device than they were over privacy concerns.

In 1996, Progressive filed for and obtained a US patent (US patent 5,797134) on their process. Progressive has also filed corresponding patent applications in Europe and Japan. UK auto insurer, Norwich Union, has obtained an exclusive license to Progressive's European patent application. They have recently completed a successful pilot test of the technology and it is now available commercially under the tradename "Pay As You Drive™"

OBDII-based system

In 2004, Progressive launched another pilot program to allow policyholders to earn a discount on their premiums by consenting to use its TripSense device. TripSense connects to a car's OnBoard Diagnostic(OBD-II) port, which exists in all cars built after 1996. The discount is forfeited if the device is disconnected for a significant amount of time.
