What automobile insurance companies do
An automobile insurance company is a business that sells you a contract — called a policy — that promises to pay certain costs if you have a car accident, your car is stolen, or someone is injured in a crash involving your vehicle. You pay the company a regular fee, called a premium, usually every month or every six months. In return, the company agrees to cover specific types of damage or injury up to the limits you choose when you buy the policy.
The company makes money by collecting premiums from many customers and paying out claims only when accidents or other covered events actually happen. They employ adjusters who investigate claims, underwriters who decide what price to charge you based on your driving history and the car you drive, and customer service representatives who handle your questions and process your paperwork.
Automobile insurance is required by law in every U.S. state if you drive on public roads. The state sets a minimum amount of coverage you must carry, but you can buy more protection than the minimum if you want it.
Key Takeaways
- Every state requires a minimum amount of liability coverage, which pays for damage or injury you cause to someone else, but the minimum varies by state and is often not enough to protect your own assets.
- Collision and comprehensive coverage protect your own car but are optional; collision covers crashes and comprehensive covers theft, weather, and vandalism.
- Your premium depends on your age, driving record, the type of car you drive, how much you drive, and where you live — not on how safe a driver you are in the future.
- Insurance companies use credit scores, zip codes, and gender as pricing factors in most states, which means two drivers with identical driving records may pay different rates.
- You can lower your premium by raising your deductible, bundling policies, maintaining a clean driving record, or asking about discounts for safety features or low mileage.
The types of coverage insurance companies offer
Liability coverage is the foundation of every auto policy. It pays for damage or injuries you cause to someone else — their medical bills, their car repair, their lost wages if they cannot work. It does not pay for your own injuries or your own car. Every state sets a minimum liability limit you must carry. That minimum is written as three numbers, like 25/50/25, which means $25,000 per person injured, $50,000 total per accident, and $25,000 for property damage. Your state's minimum is lower or higher than this example.
Collision coverage pays to repair or replace your car if you crash into another vehicle, a tree, a guardrail, or any other object. It does not cover theft or weather damage. You choose a deductible — the amount you pay out of pocket before the insurance company pays the rest. A higher deductible ($1,000 instead of $500) means a lower premium.
Comprehensive coverage pays for damage to your car from events other than collisions: theft, vandalism, weather like hail or flooding, hitting an animal, or broken glass. Like collision, you choose your deductible. Collision and comprehensive are optional if you own your car outright, but if you have a loan or lease, the lender usually requires you to carry both.
Uninsured and underinsured motorist coverage protects you if you are hit by a driver who has no insurance or not enough insurance to cover your injuries. This coverage pays your medical bills and lost wages. It is required in some states and optional in others.
How insurance companies set your premium
Insurance companies use a formula that weighs many factors. Your driving record — accidents, traffic violations, and claims you have filed — is usually the largest factor. A clean record means a lower rate. Your age matters significantly; drivers under 25 and over 75 typically pay more because statistics show they have more accidents. Your gender affects your rate in most states, with young male drivers paying more than young female drivers.
The type of car you drive changes your rate. A sports car costs more to insure than a sedan because it is more expensive to repair and is involved in more accidents. A car with safety features like automatic braking may may have access to for a discount. Your location — your zip code and whether you live in a city or rural area — affects your rate because some areas have more accidents, theft, or weather damage.
Your credit score influences your rate in most states. Insurance companies have found a correlation between credit score and the likelihood of filing a claim, so they use it as a pricing factor even if you have never missed a payment on a car loan. Your annual mileage matters too; someone who drives 5,000 miles a year pays less than someone who drives 20,000 miles.
One important thing to understand: your premium is based on your past and your circumstances, not on how safely you will drive in the future. A company cannot charge you more because they predict you will have an accident. They can only charge you more based on what has already happened or on statistical patterns in your group.
How to compare insurance companies
Insurance companies vary in price, customer service, and the discounts they offer. Getting quotes from at least three companies is the most direct way to find a lower rate. When you request a quote, you will provide the same information to each company — your driving history, the car you drive, the coverage limits you want, and your deductible. The companies will then calculate what they would charge you.
Quotes are free and do not commit you to anything. Most companies offer quotes online in minutes, by phone, or through an agent. When comparing quotes, make sure you are comparing the same coverage limits and deductibles across all three, or the prices will not be truly comparable.
Beyond price, consider the company's customer service reputation. You can read reviews on the National Association of Insurance Commissioners (NAIC) website, which collects complaints filed against insurance companies. You can also check ratings from J.D. Power or Consumer Reports. Some companies are known for fast claims processing; others for difficult claims experiences. If you have a claim, you want to know the company will handle it smoothly.
Many companies offer discounts you may not know about. Common discounts include bundling your auto policy with home or renters insurance, maintaining a clean driving record for three to five years, completing a defensive driving course, having safety features on your car, paying your premium in full rather than monthly, or driving fewer miles than average. Ask each company what discounts you might receive.
What happens when you file a claim
If you have an accident or your car is damaged or stolen, you contact your insurance company to file a claim. You will provide details about what happened, when it happened, and where. If another person was involved, you will provide their name, phone number, and insurance information. If police responded, you will provide the police report number.
The insurance company will assign an adjuster to your claim. The adjuster's job is to investigate — they may ask you questions, review photos or video, talk to witnesses, and inspect the damage to your car. They are trying to determine whether the damage is covered under your policy and, if so, how much it will cost to repair or replace.
Once the adjuster has finished their investigation, the company will make a decision: approve the claim and pay, deny the claim, or approve it for a lower amount than you requested. If you disagree with their decision, you can file an appeal or, in some cases, pursue a complaint with your state's insurance commissioner.
Why insurance companies deny claims
Insurance companies deny claims for specific reasons. The most common is that the damage is not covered under your policy — for example, you filed a collision claim but you only have liability coverage. Another reason is that you did not pay your premium, so your policy was not active when the accident happened. A third reason is that the company believes you caused the accident intentionally, which is never covered.
Sometimes a company denies a claim because they believe you misrepresented information when you bought the policy. For example, if you said you drive your car to work only occasionally but your records show you drive it daily, the company might deny a claim and say you committed fraud. This is rare, but it is why it is important to answer questions honestly when you buy insurance.
If your claim is denied, you have the right to appeal within your insurance company and, if that does not work, to file a complaint with your state's insurance commissioner. Your state's insurance commissioner's office can investigate whether the denial was fair.
How to lower your insurance premium
Raising your deductible is the fastest way to lower your premium. If you move from a $500 deductible to a $1,000 deductible on collision and comprehensive, your premium will drop when ready. The trade-off is that if you have a claim, you will pay more out of pocket. This strategy makes sense if you have savings set aside for emergencies.
Bundling your auto policy with home, renters, or other insurance policies usually earns you a discount of 10 to 25 percent, depending on the company. Maintaining a clean driving record for three to five years without accidents or violations will lower your rate when your policy renews. Some companies offer a discount for completing an approved defensive driving course, which you can often take online.
Installing safety features on your car — like anti-theft devices or collision avoidance systems — may lower your premium. Driving fewer miles than average can lower your rate; some companies offer usage-based programs where they monitor your actual driving and adjust your premium based on how safely you drive. Paying your premium in full upfront rather than in monthly installments sometimes earns a small discount.
Shopping around every two to three years is also important. Insurance companies change their rates, and a company that was cheapest last year may not be cheapest this year. Getting new quotes periodically ensures you are still getting a competitive rate.
Frequently Asked Questions
Do I have to use the insurance company's repair shop?
No. You can take your car to any repair shop you choose. The insurance company will pay the shop directly based on their estimate of the repair cost. Some shops are on the insurance company's preferred network and may have agreements about pricing, but you are not required to use them.
What is a deductible and how do I choose one?
A deductible is the amount you pay toward a claim before your insurance company pays the rest. If you have a $500 deductible and your repair costs $2,000, you pay $500 and the company pays $1,500. Higher deductibles lower your premium but mean you pay more if you have a claim. Choose based on what you can afford to pay out of pocket in an emergency.
Can my insurance company drop me or refuse to renew my policy?
Yes, but only for specific reasons: non-payment of your premium, fraud, or a significant increase in risk (like multiple accidents). They cannot drop you straightforward because you filed a claim. If your policy is not renewed, the company must tell you why and give you time to find new coverage.
Does my credit score really affect my insurance rate?
In most states, yes. Insurance companies use credit scores as a pricing factor because they have found a statistical link between credit score and claims. However, some states limit how much weight companies can give to credit scores, and a few states prohibit using them entirely. Check your state's insurance commissioner's website to learn your state's rules.
What should I do if I think my insurance company treated me unfairly?
First, contact the company's customer service department and explain your concern. If they do not resolve it, file a complaint with your state's insurance commissioner. The commissioner's office investigates complaints and can order the company to take action if they find wrongdoing. Filing a complaint is free and does not require a lawyer.
