In the United States, insurance is regulated by the states under the McCarran-Ferguson Act, with "periodic proposals for federal intervention", and a nonprofit coalition of state insurance agencies called the National Association of Insurance Commissioners works to harmonize the country's different laws and regulations.[46] The National Conference of Insurance Legislators (NCOIL) also works to harmonize the different state laws.[47]
When comparing car insurance quotes, it helps to compare apples to apples; in other words, you want to be sure that the quotes you get are for identical - or at least very similar - auto insurance policies. Once you have a better idea of the type of coverage you’re looking for in a policy, this will be easy. To better understand coverage types start here

Social insurance can be many things to many people in many countries. But a summary of its essence is that it is a collection of insurance coverages (including components of life insurance, disability income insurance, unemployment insurance, health insurance, and others), plus retirement savings, that requires participation by all citizens. By forcing everyone in society to be a policyholder and pay premiums, it ensures that everyone can become a claimant when or if he/she needs to. Along the way, this inevitably becomes related to other concepts such as the justice system and the welfare state. This is a large, complicated topic that engenders tremendous debate, which can be further studied in the following articles (and others):
Defense Base Act (DBA) insurance provides coverage for civilian workers hired by the government to perform contracts outside the United States and Canada. DBA is required for all U.S. citizens, U.S. residents, U.S. Green Card holders, and all employees or subcontractors hired on overseas government contracts. Depending on the country, foreign nationals must also be covered under DBA. This coverage typically includes expenses related to medical treatment and loss of wages, as well as disability and death benefits.

There are also companies known as "insurance consultants". Like a mortgage broker, these companies are paid a fee by the customer to shop around for the best insurance policy amongst many companies. Similar to an insurance consultant, an 'insurance broker' also shops around for the best insurance policy amongst many companies. However, with insurance brokers, the fee is usually paid in the form of commission from the insurer that is selected rather than directly from the client.

In managing the claims handling function, insurers seek to balance the elements of customer satisfaction, administrative handling expenses, and claims overpayment leakages. As part of this balancing act, fraudulent insurance practices are a major business risk that must be managed and overcome. Disputes between insurers and insureds over the validity of claims or claims handling practices occasionally escalate into litigation (see insurance bad faith).
Any risk that can be quantified can potentially be insured. Specific kinds of risk that may give rise to claims are known as perils. An insurance policy will set out in detail which perils are covered by the policy and which are not. Below are non-exhaustive lists of the many different types of insurance that exist. A single policy that may cover risks in one or more of the categories set out below. For example, vehicle insurance would typically cover both the property risk (theft or damage to the vehicle) and the liability risk (legal claims arising from an accident). A home insurance policy in the United States typically includes coverage for damage to the home and the owner's belongings, certain legal claims against the owner, and even a small amount of coverage for medical expenses of guests who are injured on the owner's property.
Retrospectively rated insurance is a method of establishing a premium on large commercial accounts. The final premium is based on the insured's actual loss experience during the policy term, sometimes subject to a minimum and maximum premium, with the final premium determined by a formula. Under this plan, the current year's premium is based partially (or wholly) on the current year's losses, although the premium adjustments may take months or years beyond the current year's expiration date. The rating formula is guaranteed in the insurance contract. Formula: retrospective premium = converted loss + basic premium × tax multiplier. Numerous variations of this formula have been developed and are in use.
At the same time, the first insurance schemes for the underwriting of business ventures became available. By the end of the seventeenth century, London's growing importance as a center for trade was increasing demand for marine insurance. In the late 1680s, Edward Lloyd opened a coffee house, which became the meeting place for parties in the shipping industry wishing to insure cargoes and ships, and those willing to underwrite such ventures. These informal beginnings led to the establishment of the insurance market Lloyd's of London and several related shipping and insurance businesses.[6]
An entity which provides insurance is known as an insurer, insurance company, insurance carrier or underwriter. A person or entity who buys insurance is known as an insured or as a policyholder. The insurance transaction involves the insured assuming a guaranteed and known relatively small loss in the form of payment to the insurer in exchange for the insurer's promise to compensate the insured in the event of a covered loss. The loss may or may not be financial, but it must be reducible to financial terms, and usually involves something in which the insured has an insurable interest established by ownership, possession, or pre-existing relationship.
Insurers will often use insurance agents to initially market or underwrite their customers. Agents can be captive, meaning they write only for one company, or independent, meaning that they can issue policies from several companies. The existence and success of companies using insurance agents is likely due to improved and personalized service. Companies also use Broking firms, Banks and other corporate entities (like Self Help Groups, Microfinance Institutions, NGOs, etc.) to market their products.[30]
Please note that this website provides only a summary of auto insurance, written to illustrate in general terms how auto insurance works. Your insurance policy is the legal contract that contains the terms and limitations of your coverage. You should carefully review the contents of your policy. All products and coverages are subject to availability and limitations. Whether an accident or other loss is covered is subject to the terms and conditions of your insurance policy.
In the United States, the most prevalent form of self-insurance is governmental risk management pools. They are self-funded cooperatives, operating as carriers of coverage for the majority of governmental entities today, such as county governments, municipalities, and school districts. Rather than these entities independently self-insure and risk bankruptcy from a large judgment or catastrophic loss, such governmental entities form a risk pool. Such pools begin their operations by capitalization through member deposits or bond issuance. Coverage (such as general liability, auto liability, professional liability, workers compensation, and property) is offered by the pool to its members, similar to coverage offered by insurance companies. However, self-insured pools offer members lower rates (due to not needing insurance brokers), increased benefits (such as loss prevention services) and subject matter expertise. Of approximately 91,000 distinct governmental entities operating in the United States, 75,000 are members of self-insured pools in various lines of coverage, forming approximately 500 pools. Although a relatively small corner of the insurance market, the annual contributions (self-insured premiums) to such pools have been estimated up to 17 billion dollars annually.[40]
