Liberty Mutual offers a few hard-to-find discounts, including savings for newly married couples, new graduates, retirees or drivers over 50, and certain drivers under 18. Some of its coverage options are on the rare side, too — like options for mechanical breakdown coverage, vanishing deductibles, or new car replacement that reimburses you for the car’s original worth (rather than its depreciated value). In short: Liberty Mutual has some niche offerings, so it may be worth speaking with an agent about specialized or customizable coverage needs.
We can help you figure out if you need rental car insurance. The short take: If you don't have auto insurance, yes, you most likely need coverage. If you have robust car insurance, you might simply need a collision damage waiver as it’s the only way to ensure you won’t pay the rental company any damages in case of an accident. Of course, it gets more complicated from there. For the long take on car rental insurance, head here.

The auto insurance market in the U.S. is dominated by a few key players. In fact, the top ten auto insurance companies control more than 72% of the market. While the top ten insurance companies underwrite a large number of policies, they have very distinct characteristics. To help you choose the best insurance company for your situation, we created a list of the top ten largest auto insurance companies in the U.S. and discuss what makes each of them unique.


The Hartford is only the nation’s 11th largest insurer, but it still packs a punch. In fact, it had the highest score in my 12-category feature evaluation (92 out of 100). It also offers a wide range of policy options and benefits (including rates based on how much you actually drive your car and a new car replacement program for cars totaled shortly after purchase) and was the only insurer to score a perfect 100 in our vehicle-discount evaluation.

Auto insurance companies attempt to predict and price the risk you and your vehicle pose in order to reduce their exposure. Keeping in mind the factors we just covered, the more risky you appear to your insurance company, the more you will be charged. Factors like age, marital status, and homeowner status, are less easy to change. Avoiding unnecessary claims, being smart with your coverage needs, and shopping around for car insurance quotes every so often are great ways to save on car insurance.

Many companies advertise free auto insurance quotes. Any car insurance quote you receive is and should be completely free. Insurance companies want to incentivize you to purchase a car insurance policy from them, so they’re not going to charge you for an upfront assessment (the quote). When shopping around for insurance, remember you can find free car insurance quotes from a variety of sources.
Amica was the strongest company overall in our research, and ranked number two in J.D. Power’s 2018 customer satisfaction report — that means out of 44,622 surveyed drivers, it had the second highest satisfaction rating among more than 20 different companies. It also received the highest Consumer Reports rating among auto insurance providers — as it has every year since at least 1999. Consumer Reports even noted that an overwhelming number of customers reported “relatively few” problems during the claims process.

Like regular car insurance, there are several parts with classic and collector car insurance. Some insurers like J.C. Taylor require your classic car be at least 19 years old, while others like Grundy will insure a car of any age. Availability of discounts should also be a consideration, as Safeco gives you a percent off your premium if you bundle your classic car policy with a regular auto policy. Another underrated feature is an inflation guard, which will increase your protection limits as your car appreciates in value. You can see a full list of each company's benefits below.
Young drivers — aged between 16 and 25 — pay very high car insurance rates, with those aged 16-19 paying the most expensive premiums of all. Because of the risk presented by inexperienced drivers, teen drivers pay more than three times the national average for car insurance. In Tennessee, teen drivers pay insurance rates in line with the national average: $4,741 per year.
This is in contrast to standard car insurance, which typically reimburses you for the car's actual cash value - the original value, minus the amount it's depreciated over time. If, for example, you purchased your car for $25,000, but 5 years later it's now worth $9,000, then that's the amount your insurer would likely pay out if it's totaled. Guaranteed Value™ coverage helps assure this isn't the case for your beloved ride.
GEICO, well known for its animated gecko, has served as an underwriter to more than 16 million auto policies, which insure more than 24 million vehicles. The company’s size allows it to employ more than 36,000 people across nine regional offices, three service centers and three claims centers. GEICO’s original customer base consisted of U.S. government employees and military personnel. Today, the insurance company’s customer base has expanded to include people in the private sector.
When shopping for affordable car insurance quotes, come in with a good idea of your vehicle's value via Kelley Blue Book and NADA. If you determine your vehicle is worth more than $4,000 but you need to save money, consider raising your deductible. Because your car insurance deductible and premium are inversely related, you can lower your bill by raising your deductible. Looking at the chart below, you can see how your premium is affected by adjusting your deductible.

By contrast, classic auto insurance usually covers your collectible vehicle for an agreed (often called “guaranteed”) value that is mutually agreeable to you and the insurance company – an amount the automobile is worth based on respected collectible car valuation guides like the Old Cars Report Price Guide, an appraisal by a professional, research conducted by the underwriter, or some form of documentation. For instance, if you own a 1957 Chevrolet Bel Air with an 8-cylinder engine and 162 horsepower, Hagerty, a leading insurer of collectible cars, would value that at about $61,000. If you have a collectible car insurance policy in place and that vehicle suffers a total loss, the insurer will compensate you the full $61,000.
Progressive impressed us with a solid array of discounts, including deductions for simple things like signing a new policy early and opting for paperless billing. The company has historically been known for insuring "riskier" drivers than many of its competitors, and it shows: Progressive is our only contender that offers a near unheard-of discount for drivers under 18 (who have a crash rate that’s almost nine times higher than that of middle-aged drivers).

Large insurance companies analyze a huge amount of customers’ personal data (like social media posts, credit scores, and even your web shopping habits). Then, they churn the data through a proprietary algorithm that estimates how likely you are to shop around or just renew your existing policy each year. By doing so, they can increase your premium just enough to raise their profit margins without attracting your attention and prompting you to shop for a new policy.
There are many reasons you may be seeking the cheapest auto insurance option. Your household finances may be tighter than usual. Or maybe you don't drive a lot. Whatever the reason, a low-cost policy doesn't have to mean a no-frills experience with the insurance company. As you compare quotes from cheap car insurance companies, consider more than just price. Policies from leading carriers, such as Nationwide, may be exactly what you need. Here's what to look for:

Like State Farm and Progressive, Allstate also offers an app that tracks your driving. Instead of getting a premium discount, Allstate’s Drivewise program gives you up to 25% cash back every six months. If you complete Drivewise challenges, such as going three days without any hard braking, you can earn Allstate Rewards points that can be redeemed for savings on top brands, like Nike or the Gap. The Allstate Rewards program is available to everyone, not just Allstate policyholders.

Since most people choose one of these large insurers, NerdWallet compared quotes from the five largest auto companies in ZIP codes across the country. Rates are for policies that include minimum coverage required in each state, plus collision and comprehensive coverage. Our “good driver” profile is a 30-year-old with no moving violations and credit in the “good” tier. Use the tabs to see rates for drivers with credit in the “poor” tier and those with one at-fault accident as reported to the insurer.

All insurers base their rates on risk. We're talking car insurance, so the company is primarily trying to determine how likely you are to get into an accident. Obviously, if you have a poor driving record or you're on the road all the time, the odds are less in your favor. But statistics show women get into fewer accidents than men as do married individuals versus single ones. Younger drivers, conversely, get into more accidents than older drivers. All that data on your demo can influence what insurers charge.


Many insurance companies offer a discount for enrolling in their telematics program, which means they’ll monitor your driving through either a phone app or small, installable tool. Some companies will offer a discount just for allowing them to track your driving, while others will monitor while you drive and offer price reductions based on your skills.
