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.
Consumer Reports offers an extremely helpful guide that highlights the steps you can take to find the best policy for your needs. Even if you’re fairly happy with your policy, they suggest shopping around to compare rates at least every two or three years. That way, you have a good idea of where car insurance rates are headed and how much you could save if you switch. Plus, it never hurts to shop around. Based on your age, your driving record, and other factors, the policy you have now could be considerably cheaper if you switched firms.
Insurance for a collectible automobile works much like traditional automobile insurance. The policy typically has a term of 12 months and includes coverage for liability, collision, comprehensive, medical payments, and uninsured/underinsured motorists. State-mandated liability coverages extend to collectible cars as well as regular private-passenger vehicles. In terms of optional coverage, apart from the standard ones such as collision and comprehensive, there are also some options unique to classic cars. Examples of options offered by most classic car insurers are:
We love classic cars as much as you do. If the love of your life is a 1957 Bel Air or a 1966 Pontiac GTO, we know your vintage beauty deserves special treatment.

Farmers Insurance fell just shy of the benchmark we set for financial stability. It took earned an “A” from A.M. Best (passing), and an “A” from S&P Global (two steps below the required “AA-”). These scores mean that Farmers has strong financials, and offers solid backing for your policy — it’s just a little less likely to weather a major financial crisis than other companies. This is why, like Liberty Mutual, we don’t rank it among the best of the best.
Nationwide’s coverage selection is more or less on par with companies like Progressive, Allstate, and GEICO. It includes all the core coverage options — from liability to uninsured motorist — as well as some add-ons that may be hard to find elsewhere, like GAP insurance, rideshare coverage, and accident forgiveness. Like other top companies, Nationwide also offers plenty of discounts. Customers can save by bundling home and auto insurance, installing safety devices on their car, taking a defensive driving course, staying accident free, and more.

Also, we accept most cars and drivers. (Yes, that means you too!) We offer free auto insurance quotes for drivers that have had a history of driving violations or accidents (in most cases considered high-risk drivers), have let their insurance expire, or have less than perfect credit. We always offer the same flexible rate plans and outstanding customer service, regardless of your driving record.

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.
The company’s discounts are numerous, varied, and designed to reward you, not just your car. It offers deductions for paying your premium on time, signing up for a policy early, and it even offers discounts for continuous coverage (renewing your policy before it expires). These types of discounts are less common than you might think, and they demonstrate that Travelers doesn’t just want to save money for its new customers — it’s concerned with keeping its old ones happy, too.

"After being with my insurance company for just shy of 10 years, and after having shopped at companies that everyone around my hometown swore were the cheapest (including unadvertised "bargain" companies and giant comparison shopping brands), I decided to shop here at Cheap Car Insurance and ended up saving just under $1,100 off my annual insurance bill, which is a lot more than I ever could have imagined anyone saving, especially me, an avid online shopper and extreme bargain hunter [...]
